Greeting from Organizer

Dear Participants,
Welcome to the Summer Institute of Asia & ASEAN Center for Educational
Research.
We are proud to announce to you the first opening of the Summer
Institute of Asia & ASEAN center for Educational Research. The Asia &ASEAN center for Educational Research was established in February 2018
based on the achievements of the Twin College Envoy Program of student
exchange “TWINCLE”. TWINCLE was started in 2012, and it was designed
to create mutual understanding among students from East andSoutheastern Asia through activities of science and education. More than
1000 undergraduate and graduate students have participated as
exchange students, and more than 25,000 high school students havejoined the science classes over the course of one decade of TWINCLE
activities. To date, 18 universities from eight countries have joined theprograms of the center.
Under the difficulty of the COVID-19 pandemic, part of the TWINCLE
activities this year have moved online. Taking this as an opportunity,
the center has recently developed the Summer Institute Program forhigh school students in East and Southeastern Asia in collaboration
with university students and faculty members. We hope you expand
your knowledge and gain fruitful experiences.

Purpose and Background:
Acne vulgaris, which the major cause is P. acnes [2], is one of the most common problems inadolescence. The chemical or antibiotic treatments used for acne medication can cause skin allergy anddrug resistant-bacteria induction problems. As we find more about the substances that can be used to treat
acne and hypoallergenic, it was found that some proteins and peptides in rice bran can inhibit the growthof bacteria that cause acne. Riceberry rice bran was selected because it has hypoallergenic properties.
Bioinformatics will save time, cost, and resources for study as it can look at upcoming trends and serve as
the base for creating a three-dimensional model of complex molecules. Therefore, we were interested ininvestigating the antibacterial efficacy of Riceberry rice bran hydrolyzed protein using bioinformatics andtesting it against acne-causing bacteria P. acnes. This would be beneficial for product development to treat
acne more effectively.
Materials and Methods:
First, searching and collecting data of proteome from 4 major proteins in riceberry rice bran fromthe Genbank database were required. Computational method microsoft excel was used to predict the
enzymatic cut site and screen for the peptides that consist of 5-50 amino acids and to convert all data into
FASTA format. Next, they were classified into size S (5-20 amino acid sequences), M (21-35 amino acidsequences), and L (36-50 amino acid sequences). Then, iAMP and DBAASP were used to screen for theirantibacterial properties and toxicity with ToxinPred, also used to select for non-toxic antibacterial peptides
candidates. Next, dPABBs, CellPPD, QSPpred programs analyses were performed for anti-biofilm, cell
penetration properties, and anti-quorum sensing properties predictions and separated them into 4 groups
according to abilities. Then, Venny 2.1.0 program analyzed the multifunctionality of the peptides. Finally,
COPid and PEP-FOLD3.5 program analyzed composition analysis and secondary structure prediction.
Results and Discussion
This study shows that antibacterial peptides have a length of 5-22 amino acids, and the secondary
structure of the peptides mostly is random coil or alpha helix. Moreover, most of the antibacterial peptides
which were studied contain hydrophobic amino acid about 21-40% and have a positive net charge.
Before AMPs can interact with the cytoplasmic membrane of Gram-positive bacteria, they have totraverse the cell wall composed of wall- and lipoteichoic acids and peptidoglycan. While interaction of
AMPs with peptidoglycan might rather facilitate penetration, interaction with anionic teichoic acids may
act as either a trap for AMPs or a ladder for a route to the cytoplasmic membrane [1]. So, the peptides
should be positive charge, which can interact with anionic teichoic acid.

Purpose and Background:Purple non-sulfur bacteria (PNSB) are a group of anaerobic bacteria that is capable of photosynthesis. Thesebacteria have many uses in agriculture and for bioremediation and they can tolerate many harsh conditions. Past
research done by Kim et al. (2004) found that PNSB can be used to effectively reduce COD and odorous compounds
in water. This is demonstrated in a swine waste lagoon. However, PNSB suspensions can be expensive, so the ability
to produce more bacterial suspensions using household materials may be useful. This study was carried out to test
various common household ingredients as culture media for PNSB.
Materials and Methods:
In this study, three nutrient sources were tested: chicken eggs, unsweetened soy milk, and bovine milk.
First, 21 grams of chicken eggs, with the yolk and the whites mixed homogenously, 67.4 grams of unsweetenedsoymilk, and 43.0 grams of bovine milk were each added to a 1.5 liter PET water bottle and water was added until
each bottle weighed 1.4 kilograms, after which, 60 milliliters of a PNSB suspension were added to each bottle. Twosets of each media were made. The OD660 of each bottle was recorded daily, starting from two days after eachbottles were prepared, for a total of 7 days.
Results and Discussion
Figure 1 shows the changes to the OD660 value of each media compared to the first day of measurement. It
can be seen that only the egg media showed a change in the turbidity of the media. The soymilk media did not show
any noticeable signs of PNSB growth. However, on the second and third day the media was producing CO2, a signof yeast growth, which might have outcompeted the PNSB. PNSB growth in a soy milk based medium has been
demonstrated by Wu, Zhang, and Li (2014). Both bovine milk media showed no signs of PNSB growth.

2. Graduate School of Horticulture, Chiba University
Purpose and BackgroundSome researches indicate that Natto (Bacillus subtilis var. natto) has inhibitory effect for plant pathogens.
Bacillus subtilis is used as a control method for pant disease, as exemplified by Botrytis cinerea,
Oidium lycopersici and Sphaerotheca humuli. It’s also applied to biological agrochemicals.
For the above reasons, I want to gain insight into Inhibitory effect of Natto for plant pathogens.
Materials and Methods
We cultivate Lettuce (Lactuca sativa) in hydroponics equipment for 35 days and set 4 experimental plots: Not
vaccinated, Vaccinated with Natto (plot N), Vaccinated with Pythium irregulare (plot P), Vaccinated with
Natto and Pythium irregulare (plot N+P).
In plot N and plot N+P, we added about 10^7cfu/ml Natto isolated from commercial one. The following day,we added P. irregulare in plot P and N+P.
Results and Discussion
After cultivation, we evaluated disease symptoms, root rot. We classified into 5 stage, depending on the
propotion of root rot; 0: none damage, 1: slight damage, 2: 1/3 damage, 3: 2/3 damage, 4: more than 2/3.
The following pictures are the root rot of Lettuce (Lactuca sativa).

Purpose and Background:
Copper oxide (CuO) is an attractive semiconducting material because it can be fabricated from copper
sheets using electrochemical deposition. Nanostructured CuO nanowires have high surface area that is suitable
for many promising applications such as solar cells, light emitting diodes, photo-catalytic, antimicrobial,
electrochemical, electrochromic and sensing applications (Zoolfakar et al., 2014).
Materials and Methods:
In this study, CuO was prepared on Cu substrates. The Cu substrates were cut into a size of 0.2 x 3 cm2 andcleaned by soaking in 37% HCl for 1 minute and in acetone for 1 minute, 3 times each. For theelectrochemical deposition of CuO, chronoamperometry at applied potential of -0.25V was conducted for 5
minutes in a 3-electrode system having the Cu substrate as a working electrode, Pt wire as a counter electrode anda Ag/AgCl as a reference electrode. 3 M KOH was used as an electrolyte. The obtained films on the Cu substrates
were then annealed at 200°C for 3 hours to give CuO films.
Results and Discussion
Figures 1 (a) and (b) show an X-Ray Diffraction pattern and a Scanning Electron micrograph of the CuO films
fabricated, repectively. A capability of electrochemical deposition of CuO nanowires has been demonstrated.

Purpose and Background
Current transportation technology is in the form of vehicles capable of traveling long distances in ashort time so as to accelerate mobilization and also fulfill human needs. However, the transportation
technology that is currently widely used is not environmentally friendly because it produces emission gasesthat pollute the air. By decreasing air quality, it will have an effect on decreasing the level of public health,especially in human respiration. If this is left alone without the right solution, it will have a bad effect on the
future. By seeing that Chlorella is able to reduce air pollution and improve air quality with its photosynthesis
process, as well as roads with many motorized vehicles passing by that produce pollutant emissions, street
light algae air purifying can be a solution.
The purpose of this research to reduce air pollution with the tool that authors make before which isnamed SLAP. After that, a trial was carried out at the Kulon Progo international airport to find out the SLAP's
effectiveness as air pollution purifier technology.
Materials and Method
Based on the formulation of the problem described in the previous sub-chapter, the methodology wechose was quantitative. Data obtained by:
1. Literature study: before making a tool that can reduce air pollution, we collected several references fromboth local and international journals.
2. Experiment: ffter getting a lot of info about algae, an innovative air purifier from algae was created.
3. Research: the research we conducted was to test how much effectiveness of SLAP can do in purifying
the air. In three different places at kulon progo international airport
The tools to make a SLAP are Battery 12 V, Aquarium, Cable, Solar Charge Controller, Solar panel,
Plywood, and Chlorella sp.. To check the effectivenes from SLAP, Air Quality Monitor used.
Results and Discussion
First, the solar panel will absorb light. The solar panel is acomponent of a photovoltaic system that has functions to convert
sunlight into electricity because it is composed of several photovoltaic
cells. The sunlight will be converted into electrical energy and stored
in the battery. When the battery is charged by the solar panel, thecharge controller will prevent overcharging to the battery by cutting off
the DC flow from the solar panel. This prevents damage to the battery
so that it can last longer. When charging is not in progress (at night),
the charge controller prevents the flow of current from the battery backto the solar panel so that power can be stored properly.Then, theelectricity is used to turn on the LED lamp. The lamps are arranged inparallel so that the light produced is brighter and support thephotosynthetic process of algae more optimally. Then the algae will
absorb carbon dioxide, convert it to oxygen, and finally clean the air.
The effectiveness of SLAP was found. At three different places theCO2 level was measured first and then after one day it was measured
again as the effect of the presence of algae as an air purifier. The
measurement results from the table that air purifier is effective to
reduce air pollution, especially from carbon dioxide by lowering thecarbon dioxide level which is in the thousands (yellow color which canbe said to be unhealthy air) to 400-500's (green color which is a signof healthy air).

Purpose and Background:
The difference in flower color of a plant called Oxypetalum was investigated by analyzing the anthocyanin structurethat forms the flower color. Anthocyanins, are pigments that exhibit a wide range of colors from red to blue, and their
hue changes depending on their structure. In general, anthocyanidins, which are the basic skeleton of anthocyanins,determine the basic color, and sugars and organic acids bind to it to change the color tone. The structure of theanthocyanin of the light blue flower Blue Star variety of Oxypetalum used in this study has already been reported in
Saito et al. (2012), and it is known that three structures of anthocyanin are accumulated. Therefore, referring to thisresult, we investigated the anthocyanin structure in other flower colors. As samples, we used a blue star that blooms
light blue flowers, a pink star that blooms pink flowers, and a blue star that changed to purple over time.
Materials and Methods:
After sampling flowers, they were frozen using liquid nitrogen and tissue was grinded with a mortar andpestle. MeOH and TFA were added to suspend. Samples were centrifuged to remove precipitate. Samples
were purified. 3N HCl was added to final concentration. Samples were heated to 100 degrees for30 minutes. Alcohol
was added and samples were centrifuged to separate two layers. The samples were purified for High Performance
Liquid Chromatography analysis. The High-Performance Liquid Chromatography was used to determine thecomposition of each anthocyanin. Each peak in the chromatograph indicates differences in structure.
Results and Discussion:
Each color was determined by different combination and the structures of anthocyanidins. The color variation isdetermined by the structure and combination of anthocyanidins. Cyanidin-3-glucoside can change with A3GXT
to Cyanidin 3-sambubioside, which gives a pink or blue color. But when A7GT exists, the pink color is not possible.
Which determines the blue or purple color. In all flower colors, the accumulated anthocyanidins were confirmed to becyanidins. The main peak in the HPLC was Cyanidin 3-sambubioside. Especially in pink star, the structure modified
to 7th place of cyanidin was not found. An explanation is that there is a enzyme gene that modifies the seventh placeof anthocyanin. There is no difference in the composition of anthocyanins in the blue star and the blue
star purple color change. The difference in flower color between blue star and pink star was considered to
be influenced by the modification of anthocyanins to 7th place. On the other hand, factors other than anthocyanin
structure are inferred in the difference between blue star and blue star color change flower color. Therefore, in the
future, we will investigate why blue stars change color by focusing on the presence or absence of enzyme activity
and pH.
Figure: Each color in thethree types of flowers of
Oxypetalum (blue star, blue
star [purple], and pink star)is determined by different
combinationsofanthocyanins. Standard isshown as reference. Peaks

Metallic Glass Nanotubes Array Fabrication
LU, HSIN-YU/ CHIANG LI-CHI/ YANG, CHIH-HAN
Jingmei Girls High School, Taiwan, Taipei
Purpose and Background
The first-ever metallic glass nanotubes were fabricated in Professor Chu’s lab in 2017. The unique properties ofstrength, toughness, and durability make these nanotubes ideal materials of solar cells, medical instruments and soon. The target of our research is to find a way to build up the complete and neat structure of metallic glass nanotubes
on silicon chips. In order to ensure the nanotubes to be neatly arranged, the silicon chips will be processed with atechnical skill, photolithography process, to coat photoresist with regularized aperture on the silicon chips. Siliconchips after the photolithography process will be called as test pieces to be easily identified. Because of having
photoresist with tiny holes on silicon chips, the last step of building nanotubes on test pieces is to tear off all thephotoresist plus metallic glass thin film that has formed while constructing nanotubes. The reason for tearing off thethin film is to increase the contact area, also to make the nanotubes become independent individuals which can let
each nanotube undisturbed by others.
Materials and Methods
The technique used for coating is based on the theory of sputtering. Sputtering is a kind of physical vapor
deposition, also called PVD. Following is about the principle of sputtering. First of all the sputtering machine needs
to be vacuumed. When it is turned on, the power will produce electric pressure, which generates electric field andfree electrons in the machine. Those free electrons will hit molecules of argon, an inert gas, and cause the ionizationof argon and electrons. Argon ions collide the metallic atoms of the target material, erode the material onto the test
piece and deposit on surfaces in the vacuum chamber. By sputter-depositing a coating of metallic glass over an array
template created in photoresist, metallic glass nanotubes are fabricated. The specific steps are as follows. First, put
the target chosen into the chamber. Then put test pieces into the load lock chamber and start sputtering. When the set
time reaches, stop sputtering and cool down the test piece for a while before taking it out of the machine. Next, soak
the test piece into acetone liquid and wait for about one minute. Last, tear off the metallic glass thin film withphotoresist on it.
FigureResults and Discussion
The photo is what our test pieces look like with metallic glass
nanotubes on it. With the help of a scanning electron microscope, tiny
tubes that are invisible to our naked eyes can be seen. On the picture,
the features of the nanotube array can clearly be seen. It shows the
thickness of the tube wall is almost the same. Also, the arrangement of
the nanotubes is extremely neat and the size of nanotubes are exactly
equal. These details represent that this way of making metallic glass
nanotubes is feasible.

mostly through delivery logistic. Therefore, this study has invented a thermal insulation from sugarcane
bagasse fiber instead of plastic for solving the problem and being a prototype of bio-wasted innovation
for food delivery packaging. The product is made from bagasse and coconut coir as the main materials
both of which can be degraded. Moreover, one of the selected materials; sugarcane, is wasted by anaverage of 6 million tons per year in Thailand. Therefore, the organizers have applied the bagasse as amain material into the product.
Materials and Methods:
The prototype contains bio-based substances which are cellulose, hemicellulose in bagasse, lignin,alpha cellulose in coconut coir. It is made in the form of a thermal insulation pad. We changed the ratioof biomaterials, compared the thermal insulation, and attached the activated materials with glues. This
study tests 3 different ratios of bagasse to coconut coir: 50:50, 70:30 and 80:20 by mass (%w/w) tofigure out the most appropriate ratio.
Results and Discussion:
From the properties testing, it is found that the ratio 70:30 by mass (%w/w) has the most insulating
performance. It can also be degraded naturally and be actually used considering properties such as
hardness, water solubility, etc. in all proportions.

Purpose and Background:
Presently, herbicides, especially Paraquat and Glyphosate, are widely used in the agricultural industry to killweeds because of their effectiveness. However, some of these weed killers are reported to cause skin cancer and canfurther develop into lymphoma and testicular cancer [1]. Furthermore, most herbicides will leave toxic chemicals in
the environment. Therefore, chemicals that are less harmful to both the user and the environment are needed. Mulch
film or weed control fabric is an alternative substance to block weed from receiving sunlight thus inhibiting weed
growth. However, mulch film and fabric can be time-consuming and create more waste in the environment.
With this, we aimed to create a weed killer based on chitosan that is friendly to the environment. Chitosan isa natural polymer that is left over from discarded crustation shells. It can be used to coat the leaf and cover the stomata
which will prevent carbon dioxide exchange and fixation [2]. Adapting the idea of the mulch film as a weed killer,hydrogen peroxide was also added into the substance so that it can cause oxidative stress in plants. Hydrogen peroxide
is a reactive oxygen species usually used on the skin to prevent infection. Hydrogen peroxide can be broken down
into oxygen and water which will not leave any harmful effects on the environment [3]. Our biodegradable mulch
film will be effective and act as a weed growth inhibitor and can help solves the problem in the agricultural industry.
Materials and Methods:
Mulch films applied as weed killer were prepared using 3 different coating materials: Microcrystalline
Cellulose (MCC), tapioca starch (TS), and chitosan (CT). The chitosan with a molecular weight of 265 kDa wasdiluted with 0.5% acetic acid and stirred at room temperature overnight. The 8% (w/v) of each coating materials weremixed with 0.1% (v/v) Silwet 408. The mulch films were prepared with or without 1% (v/v) hydrogen peroxide(H2O2). The spray treatments were divided into 7 following mixtures: MCC, TS, CT, MCC + H2O2 , TS + H2O2 , CT
+ H2O2 , and using water as control treatment. The coating mixture of mulch film was sprayed to run off on the cocograss (Cyperus rotundus). Plant growth was observed and its survival rate was recorded every day for 10 days.
Results and Discussion
After 10 days of spraying each coating material, it was found that the grass sprayed with the microcrystalline
cellulose and tapioca starch alone or combined with hydrogen peroxide did not show any changes similar to thecontrol treatment. In contrast, the weed sprayed with chitosan combined with hydrogen peroxide started to wilt on
the second day and continued to show wilting and leaf yellowing, resulting in 70% plant death. Furthermore, theweed sprayed with only chitosan also showed 30% plant death. The wilting and leaf yellowing could be due tochitosan coating forming a film covering the stomata and inhibit gas exchange. In addition, chitosan was also reported
to induce stomatal closure [2]. Therefore, the photosynthesis capacity of the plants was reduced. Taken together, weconclude that chitosan with hydrogen peroxide is the most effective coating material to use as biodegradable mulch
film inhibiting plant growth. In the future, we planned to mix squid ink in different concentrations to the mulch film
and tested it. When spraying the coating mixture on weed, the black pigment will block the chlorophyll fromabsorbing the light and stop the plant from photosynthesizing. We hope that our biodegradable mulch film with squid
ink will be effective and solve the problem of herbicide danger to people and the environment.

STUDY THE PROTECTIVE EFFECT OF HERBAL EXTRACT ON MYOCARDIAL
INFARCTION
Luu Ngoc Phuong Linh1
1. HES High school, Vietnam
Purpose and Background:We have already known stroke and heart attack are serious diseases that appear when the blood flowing to the tissue ispartially or completely reduced. The reperfusion of blood to the tissue can reduce damage to the brain and heart muscle.
However, replenishment leads to a large-scale oxidation of lipids and protein, resulting an imbalance between free radicals
in the cells; and possibly ultimately causing further muscle depending on oxygen transport by blood and blood flow.In
recent decades, there has been great progress in screening and identifying natural compounds to develop new drugs.
Medicinal plant has played the important role in the Vietnam healthcare system. In which, ginseng extract consists ofconstituents which play the important roles against diseases. Here, we study the protective effect of herbal extract on
myocardial infarction.
Materials and Methods:
In this project, required materials incude: Vu Diep ginseng extract, H9C2 cells, Cobalt Chloride 300µM (CoCl2), CCK-8
assay kit, Plate reader: 450 nm abs, DMSO, 96 well plates, … To achieve our goals, we will be using some following
methods. Firstly, ginseng extract will be extract from ginseng root. Then, we chose Cobalt Chloride to stimulate the
Miocardial infraction (hypoxia/reoxygenatin–HR) model on H9C2 cells. After a period of researching, we made ourexperimental design. Firstly, the H9C2 cells were cultured at 37’ degree Celcius with 5% carbon monoxide. Then we
divided them into 2 groups, control and HR-CoCl2. In the control group, H9C2 cells were cultured at in normal
conditions. On the other hand, in the test group, H9C2 cells were grown in DMEM contain CoCl2 in 24h. Then cells were
continued to culture in DMEM contain DMSO or GE. Finally, the same were analyzed by cell viability (used CCK-8) and
Mitocondrial function (NAO and TMRE kit).
Results and Discussion:
After applying the methods in our study, we came up with two distinct results.The first rresult is disease model
approaches. To start off, the cell is stored in liquid nitrogen, being reactivated in 37’ degree Celcius when needed. Afterbeing cultured, the cells will be transported into the MI model for testing. Finally, the remaining unused cells along withthe cells after testing will be put back into the liquid nitrogen storage. Up next is the research about the MI model.
The second rresult is cell viability and mitochondrial function result we have put out pictures of the cell viability andmitochondrial function of H9C2 cell in the difference conditions.

The cell viability of SVD groups were significantly higher than that of HR group. This indicated SVD strongly protectedcardiomyoctes against myocardial infarction and optimal dose is 10 μg/ml. Therefore, we have chosen a concentration of
10 µg/ml for the next experiments. We continue to evaluate the influence of SVD on mitochondrial function through 2
indicators: Cardiolipin and mitochondrial membrain potential.

The NAO intensity (label Cardiolipin) and TMRE intensity (mitochondrial membrain potential) of SVD group was
dramatically higher than HR group. This indicated SVD effectively preserved mitochondrial function against injury.
Taken all together, our data presented that GE suppressed myocardial infarction by increasing cell viability and preserving
mitochondrial function. Further, evaluating the protective effects of GE against CoCl2 induced oxidative stress targetingto cellular respiratory organelle.

Narumi Ezoe

Ichikawa High school, Japan
Purpose and Background
This research aims to make an effective use of peanut shells to solve the garbage problem. Currently, about 1,600
tons of peanut shells are annually discharged in Chiba Prefecture. Peanuts are roasted after harvest to make them asnack or part of a snack. Therefore, the research materials are a roasted peanut shells because most of the discarded
shells are roasted. Cellulose nanofibers are valuable materials based on various characteristics, such as high water
retention and strength, and are used in diverse applications such as food, medicine, cosmetics, and health care [1].
According to a previous experiment using coffee beans, the cellulose nanofiber contained in the peanut shell ispotentially extractable (2).
Materials and Methods
TEMPO extracted method for peanuts cellulose nanofibers was referred by the spent coffee grounds method [2].
1. Preparing the materials: The roasted peanut shells were crushed in a blender and made into a fine powder. The
powder was washed with hot water to remove contaminants and let dry.
2.TEMPO oxidation treatment: Put the shell powder into distilled water containing TEMPO and NaBr. Stir for 3
hours while controlling pH using NaCl or HC1. The pH was adjusted between 10 and 10.5 during the reaction. Whenthe pH became stable and did not change for more than 10 minutes, ethanol was added to terminate the reaction.
3. Cleaning process: The resulting jelly-like product was filtered with a vacuum and washed two times with distilledwater.
4.Observation: Extracted nanofiber was treated with butanol and lyophilized for six days, and then observed with
Scanning Electron Microscope (SEM).
Results and Discussion

Thick fibers and membranous structures were observed from both materials (Figure1 A and B). But cellulose
nanofibers-like structures were not shown in those pictures. For solubilization of the fiber, Noriko et al. [2] used asonicator. However, after drying, the specimens were directly treated for the SEM observation. This modification
may affect the results. Therefore, extraction and treatment steps will be modified to get a clearer image of the fibers.

USING SOLAR STERILIZATION TO REDUCE THE RISK OF GETTINGDIARRHEA FROM DRINKING WATER
Cao Phương An
1. The Olympia Schools, Hanoi, Vietnam
Purpose and Background:
Water sanitation remains to be a prominent challenge for many developing nations around the world
with 2.2 billion people globally recorded to lack access to safe drinking water. In Vietnam, for example, remotecommunities and ethnic minorities are susceptible to lack of clean water, which leads to multiple serious
consequences such as “diarrhea, pneumonia and parasitic infections”, according to UNICEF. A major cause of
these alarming situations is that water filtration systems are still unavailable, or poorly developed, in multiple
areas due to their high costs.
One prospective solution to the problem is the use of solar sterilization to purify water. This is expected
to be an inexpensive method to yield water that lowers the chance of getting diarrhea in consumers.
Materials and Methods:
Materials required to perform solar water sterilization include clear and clean plastic bottles and lowturbidity water. To perform solar sterilization, one needs to fill bottles and shake them so that the water can
oxygenate. Afterward, place the bottles on a roof and leave them there for 6 hours to 2 days, according to theCenters for Disease Control and Prevention (CDC). The UV lights, heat, and “photo-oxidative destruction”
damage bacteria’s DNA and inactivate the harmful organisms.
To measure whether the water in the bottles is drinkable, tests must be conducted. One can send water
samples from the bottles to laboratories in order to determine the level of bacteria in the water.
Results and Discussion
In the past, solar sterilization has been provento inactivate diarrhea-causing bacteria in thelaboratory, according to the CDC. Moreover,according to BMJ Journals, in ten studies regarding theeffectiveness of solar sterilization conducted in Africa,
Latin America and Asia, which consisted of “5795children aged from 1 to 15 years”, eight studies yieldedsignificant statistical improvements in the risk ofdiarrhea in children, as shown in the figure beside.
Overall, the risk ratio of children getting diarrhea in all
ten studies is 62%, meaning that the chance of getting
diarrhea decreased by 38% when the solar sterilization
method was applied.
The above result suggests that solar
sterilization is an effective, inexpensive measure to temporarily provide relatively safe drinking water for people
in developing countries. However, given its low capacity to filter water at a time and its incomplete eliminationof diarrhea-causing bacteria, qualified water filtration systems are still needed.

Search for foods that inhibit the growth of oral bacteria
Kenta Oguma
Ichikawa High school

Purpose and Background:
Teeth are important for health maintenance. Efforts to protect tooth health, such as brushing and plaque control,
are ongoing. However, some people could not perform or get in touch with those protections. Therefore, find a way
to keep teeth-health from preventing periodontal disease by using common foods is beneficial.
This report examined the ability of fermented foods, Natto and Kimchi, to inhibit the growth of the Mutans
bacteria.
Materials and Methods:
Materials: Mutans selective medium (Dentocult SM, OralCare. Inc), Culture tube, Constant temperature bacteria
incubator, Dental floss, cooked Rice, Natto, and Kimchi.
Methods: Volunteer brushed teeth and then chew Rice with/without Natto or Kimchi evenly and thoroughly in themouth. After eating those foods, the volunteer did not take anything other than water. After more than 6 hours,
plaques were taken from between volunteers’ teeth with dental floss. The ingested plaques were applied on theculture sticks, and then those were placed in a culture tube containing a mutans selective medium, then incubate in aconstant temperature bath at 37 ° C for 48 hours. Microscopic Photographs of colonies were analyzed by using theImageJ (NIH), and then colony numbers and growth areas of mutans were evaluated by SPSS.
Results and Discussion:
The addition of Natto or Kimuchi slightly reduced the number of colonies in the oral cavity after more than 6 hoursof taking foods. However, that suppressive effects were not significant. On the other hand, those fermented foods
significantly reduced the growth area of mutans. These results were shown that eating those foods during the meal
may have the potential to minimize teeth decay. Therefore, it could be used to develop new health foods in the future.

THE ERA OF COVID-19
Aretha Putri1, Masterino Wisam Wannawijaya1
1. SMAN 3 Yogyakarta
Purpose and Background
Coronavirus Disease 2019 (COVID-19), that is caused by the severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) is a disease that aims for the human respiratory system (Murthy, et al. 2020). Weakimmune response will cause viral replication in host cells (Zhu et al., 2020). Sambiloto is one of the plants that canbe used as an immunostimulant. The ethanol extract of Sambiloto (Andrographis paniculata) contains alkaloids,
carbohydrates, saponins, proteins, phytosterols, phenolics, flavonoids and glycosides in phytochemical screening(Rajalakshmi and Cathrine, 2016). Sambiloto leaf extract contains andrographolide, while
14-deoxy-11,12-didehydroandrographolide is immunostimulatory (Chao and Lin, 2010). Therefore, researchers
innovated to investigate the effect of sambiloto extract (A. paniculata) as an immunostimulant using chicken

REVEAL THE SECRETS HIDDEN IN FORAMINIFERA TESTS USING MICROCT-SCANNING TECHNIQUE: GLOBIGERINOIDES FISTULOSUSTRILOBATUS SACCULIFER EVOLUTION SUCCESSIONSLu Chen Han1, Li Lo2, Katsunori Kimoto3
Taichung Girls' Senior High School, Taiwan
Department of Geosciences, National Taiwan University, Taiwan
Research Institute for Global Change, JAMSTEC, Japan
Purpose and Background:Foraminifera is a phylum of Protozoa organisms, and most of them living in the ocean including the seafloor andsurface layer. Their main habitat is tropical seas. Because they have lived for several hundred million years and theirshells are mostly made in calcium carbonate which would not easily dissolve in the sea, foraminifera is used as anarchive that makes many contributions to the research of biostratigraphy. There is a kind of foraminifera called
Globigerinoides fistulosus, its last-appearance datum is around 1.77 million years ago (Ma). However, Chen (2006)
mentioned that there are uncertainties of identifying the two species due to the morphological similarities that G.
fistulosus and Trilobatus sacculifer share. All of them bring up questions when identifying G. fistulosus. Nowadays,
T. sacculifer still can be found in modern ocean, so many studies are using it. But there are only a few studies about
G. fistulosus. To deal with this issue, we would like to understand G. fistulosus by testing their morphologicaldifferences.
Materials and Methods:
The samples of foraminifera were collected from Ocean Drilling Program Core ODP 1115B (9º11'S, 151º34'E; water
depth: 1148.8m). The sediment samples were washed and hand-picked under binocular microscopes. The
foraminiferal tests Micro-CT scanning is performed by Research Institue for Global Change, JAMSTEC, Japan(Iwasaki et al., 2015). Here we use Molcer Plus, a 3D image visualization and processing software (WhiteRbbit
Corporation), to reconstruct the 3D model of the samples. With the 3D model derived by Micro-CT scanning, we canobserve the structure of the samples clearly and measure their characteristic more accurately. Furthermore, thesamples are not damaged and can perform other analyses.
Results and Discussion:
We have initially reconstructed the samples of 4 different morphotypes across the last occurrence datum of G.
fistulosus. Currently, we are working on pretreatment of 3D models. We use different CT-number to test and get ridof impurities such as clay and other microfossils. Through their appearance, we found that these three forms of T.
sacculifer and G. fistulosus are apparently different (please see figures below). The last or second last chamber of G.
fistulosus has an irregular protrusion, but T. sacculifer doesn’t have the protrusion. To explain the result, we have twoworking hypotheses. The first is that they are two different species. The second is that they may be part of the growth
process, and G. fistulosus is the last form. Because the last chamber of Kumar form has a protrusion that is just not
as much as G. fistulosus. The goal of this research is to try to identify which hypothesis could better explain tour
results. We will test the other morphological characteristic (growth rate and thickness of tests) to further address theirevolutional relationships.

1. Mahidol Wittayanusorn School, Nakhon Pathom, Thailand
Purpose and BackgroundGame-Based Learning (GBL) has become one of the widely used methods of studying [1]because of its remarkable ability to motivate players into learning and taking interest in the knowledge[2]. With the fascinating properties of GBL and the importance of elements and compound topic in
chemistry, SciBEAM has been developed as a mobile game on the purpose of promoting education andthought process in the topic of ‘application of elements and compounds in everyday life’, with theconcept of using the Match 3 game to induce the understanding of chemical formula.
Materials and Methods
We developed SciBEAM using Unity game engine. The process includes researching chemicalelements and compounds to apply in each level of the game, developing the game using C# language,
and creating assets for the game. For performance testing, we conducted a study with students from
grade 4 to grade 9 (n = 21) including pre-testing the students with 25 multiple-choice problems in thegame’s topic, letting the students play SciBEAM independently for 2 days, doing a post-test with thesame condition as the pre-test, and also letting the players assess their satisfaction using a survey. Then,
we analyzed the data: the pre-test and post-test scores and the satisfaction survey. Finally, we concluded
the results.
Results and Discussion
The results conclude that students’ post-test scores are higher than their pre-test scores at asignificant level of 0.01, proving that the students significantly gained knowledge in the topic of‘application of elements and compounds in everyday life’ from playing SciBEAM. In the part of thesatisfaction survey, the satisfaction of the students from playing this game is in the range between highand highest. Therefore, this indicates that the students were satisfied with the concept, system andgraphics of the game.

iTRASH: Electronic Trash Management
Gregory Hope Soegiantoro1, Dhestina Syarifiah Berliani1, Eka Ningrum Rakhmawati1
1. 3rd State Senior High school of Yogyakarta, Yogyakarta
Purpose and Background
Only 10 percent of trash is recycled in Indonesia, causing overload in landfills and various health andenvironmental problem, including trash pileup in rivers and sea. Society involvement in reducing, reusing, andrecycling waste often limited by accessibility and easiness of waste management. People often don’t consider
recycling because too much effort spent for little revenue. Waste banks in several cities in Indonesia hasn’t beeffective because less people recycle their waste through waste banks. Therefore, this preliminary research is to create
an app that can encourage society in recycling daily wastes easily through waste banks.
Materials and Methods
This prototype was made using Microsoft Visual Studio, Xamarin Studio, and Apache Cordova. The app was
designed using Unified Modelling Language. Then the system design was implemented by database making,application making, and debugging. The software that has been made then has it function tested.
Results and Discussion
In this preliminary design, the prototype of iTrash has been made. iTrash is an app to connect within people
and waste banks. People can sell their daily waste for recyclement in waste banks, meanwhile waste banks can sell
their recycled products to the users.
The features of this app are trash pickup service, trash selling service, recycled products online shop,
help/customer service, and educational contents about waste management. In this app, user doesn’t have minimum
trash value to be picked up and only need to sort within organic, non-organic, and mixed waste. By simplifying thistrash sorting by the user, it is expected that more people will recycle their waste through waste banks. Hence, wastebanks input expected to increase. Meanwhile, the trash educational contents are expected to increase trash awarenessin society, that also can increase waste banks input.
Waste banks can sell their recycled products through the app and can be bought by users. By selling waste
products through the app, waste banks can expand their marketing and it is expected that waste banks output will
increase.
The increase of waste banks input and output can increase the waste banks capacity and also expand job
opportunities to people around the waste banks. By increasing the waste banks capacity, it is expected that wasted
waste will lessen and problem caused by trash. However, empirical study still needed to determine how much thisapp can affect the society.

Kasetsart University Laboratory School, Center for Educational Research andDevelopment, 50 Ngamwongwan Rd., Ladyao, Chatuchak, Bangkok 10900 Thailand.
Purpose and Background:
The increasing popularity of computers corresponds to the growing number of computer worm
infections and attacks. On account of this, a research on worm type malwares is needed. The purposeof this study is to gain an understanding of the behavior and effects of computer worms through theprocess of basic static and dynamic malware analysis in order to find an effective method of computerworm prevention.
Materials and Methods:
In this study, six computer worm samples including Win32.expiro, Michelangelo,
Win.32.Kido, W.32.CodeRed.Worm, W.32.Hybris.Worm, and Win32.Serab were analyzed. For eachsample, the obtained hash values calculated by HashMyFiles software were entered into VirusTotal
website to find any connection between the malware and IP addresses or website domains. Next, thesample was allowed to run and Process Explorer software was used to find the number of DynamicLink Library files that had been interfered by the malware. After the malware process had been
terminated, the changes in the system’s registry values were displayed by Regshot software. The
entire process was conducted in a virtual computer system made with VirtualBox software.
Results and Discussion
Table 1 shows the number of security vendors that detected the malware as a threat, thenumber of connections made between the malware and IP addresses, the number of Dynamic-Link
Library files interfered by the malware, and the number of registry values added, deleted and modified
by the malware process.

Table 1. The analyzed results of six computer worm samples.
It can be concluded that computer worms are able to damage computer systems by interferingwith Dynamic Link Library files and by modifying the registry values in the system. For preventive
measures, the hash values of a suspicious file can be calculated and entered into virustotal.com tocheck if the file is infected. If a computer is suspected to be infected by worms, Regshot and Process
Explorer can be used to detect the process caused by the computer worm.

Fighting the Infodemic: High School Students vs Adults
Pelangi Savana Puspa Romadoni, Andi Kavi Satyagir
1. SMA Negeri 1 Bandung, Indonesia

Purpose and Background:Around 6000 people have been hospitalized due to misinformation about COVID-19 in the first 3 months of2020. Hoaxes can trap people into believing something that can ultimately cost someone's life. Based onstereotypes of adults (45+), they tend to trust and share more misleading information than younger
generations. The purpose of the research is to compare the digital literacy skills of the older generations andyounger generations.
Materials and Methods:
The method used for this research is a quantitative research method. Google Forms survey is created andcompleted by 280 participants (adults, highschool students) with 2 sets of questions:
1. 1st SET OF QUESTIONS, SELF-ASSESSMENT:- “Do you know the steps to differentiate between fake news and real news?”- “In your opinion, has the Indonesian government done enough to stop the spread of fakenews as well as correct them?”
2. 2nd SET OF QUESTIONS, DIGITAL LITERACY ASSESSMENT:- 7 questions that included screenshots of news from various media.

Results and Discussion
Students and adults achieved similar accuracy percentages. Additionally, the majority of both groups know
the steps to differentiate fake and real news. (57% students, 64% of adults) and the majority of both groups
thought that the Indonesian government hasn’t done enough to stop the spread of fake news as well as
correcting them. (70% of students and 65% of adults).

ThailandSurvey of the existence of Informal Green Spaces (IGS)
in urban areas and awareness of IGS
Yuri Tanaka1
1. Ichikawa High school, Japan
Purpose and BackgroundIn a previous study, informal green spaces were surveyed in Ichikawa City, Chiba Prefecture, Japan. Informal GreenSpaces (IGS) is the Green Space other than official green spaces such as parks and forests. The previous study showedthat citizens, mainly elderly people, were aware of IGS and viewed them as potential auxiliary green spaces. Fromthese facts, the purpose in this study is to investigate whether IGS exist universally in the urban cities and younger
generation see IGS as a potential supplementary green spaces. The purpose in this study is to investigate whether
IGS exist universally in the urban cities and younger generation see IGS as a potential supplementary green spaces.
Materials and Methods
The existence of IGS and their types have been investigated near Chiba University, in the urban area. Then based on
the obtained data, a questionnaire was created, and the responses were collected from Ichikawa Gakuen’s students(junior high school to senior high school) and faculty members. Obtained answers were analysed using spreadsheet
software. How we can utilize the IGS are also considered.

Results and Discussions

IGS are found in the areas near Chiba University. All the nine types of IGS shown in the previous studies were found(Fig.1). From a survey with Ichikawa junior-high and high school students and faculty members, who are living inurban areas, I have concluded that IGS are found universally in several cities throughout urban area. Through theanalysis of the questionnaire, I have reached the conclusion that IGS play a complementary role to formal green
spaces and enrich the lives of people in younger generations (Fig.2). From one of the results, “perspective of whether
IGS make us peaceful” and “the degree of recognition of IGS, in short, number of IGS” are likely to related.

2. Chiang Mai University, Chiang Mai
Purpose and Background:
Climate change is now considered to be asignificant problem in the world including in
Chiang Mai, the northern part of Thailand,
especially agriculture. When the farmers cannot
forecast the weather, their plants end up dying
due to lack of water or flood caused by anenormous amount of rainfall. Consequently,
this research’s purpose is to find the trend ofboth temperature and rainfall change between
2019-2021 and find the correlation between
them and other factors.
Materials
The data was collected from the Thai
Meteorological
Department,
Northern
Meteorological Center, Thai Pollution Control
Department

1. In April, the amount of rainfall increases
every year because the rain cloud has
increased.
2. The rainy season has been shortened
throughout the year due to the rain clouds
gone quicker.
3. Despite the short of the rainy season in 2021,
the overall rain amounts increased especiallyin August. This is also caused by the greaternumber of rain clouds.
4. Over the period, the temperature stayed thesame level. However, in April (2021), thetemperature decreased. This is due to theincreasing of rainfall and the drop of air
pollution (PM2.5)

Methods
1. Determination of study site: Chiang Mai

Bagus Hermanto², and Komang Gede Putra Airlangga²
1. SMA N 4 Denpasar, Bali, Indonesia
2. Udayana University, Bali, Indonesia
Background and Purpose
A number of people died due to lack of concern about health in their own area. Whether it's fromphysical health, mental, or social welfare. Many lives are in danger of leaving because of bodily injuries
and mental disorders.This topic is a problem that is often found in society. And very supportive if things
like this are rarely noticed by people. But are you aware that this will greatly affect your future life? If it
stays like this, human life might not be good for the next few years.
Therefore, I bring up the topic about "Good Health and Well-being" so that all of you can pay more
attention to one of these important things. Starting from the beginning of the problem to the end how theresult. Another goal is that you can better understand health (physical and mental) and also social welfare
so that human life on this earth becomes better.
Materials and Methods
This main problem looks trivial but has a huge impact on the birth rate and death rate in the world.
If physical illness increases, it will require more medical personnel. If many people have mental disorders,many people will commit suicide. If there is a welfare problem, it also results in neglected society and theeconomy.
One of the methods that might be used is to prepare more medical personnel for the sick people,
the existence of public health programs, provide more health services in remote areas, and free medical
check-ups. The second method for mental disorders are socialization about the importance of mental health,and free treatment And lastly, we can do assistance for abandoned children, legal action for violent
treatment, and donate some funds for the welfare of the people who can or cannot afford it.
Result and Discussion
The result is after being advised and monitored continuously by World Health Report (WHR),
countries around the world are experiencing improvements in their health and well-being. World HealthOrganization act in a case like this, and also they have succeeded in urging the countries of the world tocare more about their citizens. However, in conditions of unequal access to services and the need forchanges in people's behavior, the state is still monitoring behavior in the community
In the beginning, people suffer from indifference to themselves. Stress due to social life, physicalabuse, and mental problems. And after being observed by the World Health Organization (WHO), many
people began to realize how important it is to live a healthy and prosperous life. So in conclusion, careabout your health and that of others. That way we can make the world to be a better place.

Biodegradable Nursery Pot from Used Tea Grounds
Nat Wongsirimaetheekul, Bussakorn Wongparn
Kasetsart University Laboratory School, Center for Education Research and Development,
50 Ngamwongwan Rd. Ladyao, Chatuchak, Bangkok, 10900 Thailand.
Purpose and Background
Thailand is an agricultural country. When farmers grow crops from seeds, they often use nurserypots or nursery bags that are single-use plastics for a short time. When the seedlings grow at an appropriate
point, farmers transfer them from nursery pots or bags into the soil. These plastic bags are torn and oftencauses damages to the roots of the seedlings, which might later affect their growth. At the same time, more
and more used tea grounds are discarded from tea shops and researcher’s home as waste. According to K.C.
Willson (1975), tea grounds contain essential nutrients for plants (Nitrogen) and are easily degradable.
Therefore, the researcher would like to use the tea grounds to make nursery pots to cut back theamount of waste, reuse used tea grounds and reduce the plastic problems. This research was to study theprocedure and proper ratio of used tea grounds and binder for making biodegradable nursery pots. Also, thegrowth of the selected plant, basil, that is planted in the nursery pots was observed.
Materials and Methods
The materials used in this research were used tea grounds, tapioca starch, water, octagon shape pot
mold, universal indicator, and basil seeds. First, relevant research from various sources was studied. To
make pots from used tea grounds, the researcher tried different ratios of tea grounds to binder to form thepots. The pH of the pots made from the best ratio was then tested. After that, the effectiveness of the nurserypots was tested by growing basil seeds in them. Finally, the growth of basil seedlings was recorded andreported.
Results and Discussion

Test 3Day 1

Making pots in the mold didn’t work because the pots
broke when taken out. Apart from that, 1 : 1 of used tea
grounds : binder, is the proper ratio to form the pots while
the material from 2 : 1 and 4 : 3 could not be formed.

MovingDay

The proper ratio to form the biodegradable nursery pots is 1:1 of tea grounds and binder when thebinder is made from tapioca starch and water with the ratio 1 :10. The pH of the pots was 7 which is a good
fit to most plants. In every test, the selected plant, basil, could grow in the nursery pots from tea grounds
and the nursery pots can form and keep their shape until the seedlings were transferred.

1. SMA Negeri 1 Lembang, Indonesia
2. Universitas Pendidikan Indonesia, Indonesia
Purpose and Background:
The purposes of this research are making a simple biogas reactor that is affordable, and analyzing thedifference different rate of biogas production from the two reactors.
This research conducted because Lembang is one of the agricultural and livestock areas in Indonesia. The
agricultural and livestock industries carelessly dump most of their waste into the Citarum River, making it one ofthe dirtiest rivers in the world. The waste is also dumped into the surrounding environment causing many problems,
one of which is causing unpleasant odors and dirty water absorption. The solution of this problem is to utilizing thewaste into biogas by making a simple biogas reactor. Based from previous research, biogas from cow dung can beused as alternative fuel in Prabumulih (Oktavia & Firmansyah, 2017).
Materials and Methods:
Several materials that used to create a simple biogas are drum, sok drat out and in, fitting drat, stop faucet,
pressure gauge, iron faucet, car tires, funner, hose clamp, different size pipes, various kind of glue, hose tap watertape.
The methods for making this simple biogas reactor are (1) sketch a biogas reactor; (2) create a stool inlet, gas
inlet, and place a pressure gauge on the drum cap; (3) make a faecal drain next to the drum; (4) glue all the joints
with glue then wait for it to dry, and then the biogas reactor is ready to use.
Results and Discussion
The observations were analyzing the comparison of biogas produced from 2 reactors. Where as reactor 1
contains 45 kg of cow dung waste and reactor 2 contains 15 kg of cow dung and 30 kg of agricultural waste. Hereby the table of pressure observations on tires connected to hoses from each reactor for 9 days.

Based on 9-day observation, reactor 2 produce biogas faster than reactor 1, marked by the higher change ofvolume of tires. It means the tires get more pressure from the gas inside the reactor. In conclusion, making biogas
by mixing cow dung waste with agricultural waste is better than just by cow dung waste.

Results and Discussion

Purpose and Background
Soil is one of the renewable natural
resources. It is the basis of our nation’s
agroecosystems. Healthy soil provides essential
nutrients to forests and crops, filters water andhelps to regulate the earth’s climate. Moreover,
it is vital for human needs, so we can’t deny thathumans gain benefits from soil as a foundation
for cites, a holding facility and other needs.
Nevertheless, there are considerable soil
problems in Chiang Mai which are caused bymany factors, such as shifting cultivation, soil
degradation and retrogression, and a rapid city
development in the past few years. Therefore,
this study aims to find out if Chiang Mai people
use soil proportion appropriately and how
effective the soil has been used.

Methods

1. From the study, most areas in Chiang Mai
are covered by fertile forests (around 70% of
the total areas). However, the potential of
having buildings and communities in urban site
are gradually inclining which might invade thenatural resources in the future according tosatellite image.
2. On the other hand, there are massive ofagricultural lands in rural area (around 24% of
the total areas). Thus, we can conclude that
local people living still rely on agriculture andcultivation. To keep this culture and tradition
persist, we need to pay attention at sustainable
development in soil resources.

Possibility of using informal green space tosupplement urban green space
Yuta Kawaguchi
1, Ichikawa senior high school 11th grade,
2. ASCENT program, Chiba University
Background Today, many new cities are being planned and developed around the world as a result ofindustrialization. In addition, the world's urban population is expected to grow from about 30% in 1950 to 68% by
2050 (United Nations (2018). 2018 Revision of World Urbanization Prospects). Unregulated urbanization will leadto the loss of more greenery (vegetation) and nature. Urban green space is considered essential in urban planning.
However, it costs a lot of money to create, maintain and manage these urban green spaces. On the other hand, there
are green spaces around us that are not managed by the public. Furthermore, due to the spread of coronaviruses,
people are increasingly working and living in their homes and neighborhoods, and the greenery around them has
become essential.
Purpose. We will target the greenery that exists around us (informal green space),what is not usually paid muchattention to, and clarify the awareness that people have of these green spaces, so that local people can reaffirm thevalue of green spaces
Materials and methods
Informal green spaces are defined as naturally occurring vegetation that has not been intentionally planned or
managed.1). For example, road greenery, land, gaps, railroads, brownfields, riparian areas, structures, microsites, andpower lines. In the questionnaire, we used photographs of informal green spaces that actually exist in the target area.
After obtaining the approval of the head of the community association in the Takanodai area, the questionnaire
information was distributed to each dwelling unit, and the format was to be answered online.
We conducted a field survey (including photography) to confirm the existence of unofficial green spaces in the
Takanodai area of Yotsukaido City (area of about 30 ha). Next, we surveyed the citizens residing in the target area
about their awareness of informal green spaces. The figure shows the classification method of informal green spacesin the field survey.
Results
530 copies of the questionnaire were sent to the Takanodai area of Yotsukaido City, and 133 responses were obtained.
This questionnaire was distributed randomly from 1 to 4 block. In terms of the attributes of the respondents, the ratioof males to females was equal, and the ages of the respondents were surveyed from their teens to over 70s. In Graph
1, 77.3% of the respondents felt that informal green space is a good place for living things to live. In Graph 2, 36.3%
of the respondents felt that informal green space were dirty, and 26.5% felt that they were not dirty. In Graph 3, when
asked if they thought it was important to coexist with plants and animals, 94.7% of the respondents thought it was
important.

Discussion
We limited the scope of the survey to the Takanodai area of Yotsukaido City, and obtained responses from avariety of age groups using photographs of informal green space in the target area. As a result, we clarified theattitudes people have toward informal green spaces.
In the Takanodai area of Yotsukaido City, it was found that the majority of people wanted to coexist with plants
and animals and felt that the informal green space was a home for living things. In other words, informal green
space can be an important place to protect ecosystems, and we believe that informal green space has the potential tocontribute to the creation of a healthy and comfortable city to live in, as stated in Goal 11 of the SDGs.
Our future task is to make the results of this survey known to the citizens of the Takanodai area of Yotsukaido City,
so that they will be aware of the existence of informal green space around them.

Purpose and Background
This article has been an academic contribution to conduct partnership within public participationin achieving sustainable development goals. In this context, the partnership would be implemented insolving disruptive conditions caused by Covid-19 pandemic, especially in the educational sector.
Indonesia as the developing countries still committed to implement Sustainable Development Goals(abbreviated as SDGs). The seventeenth SDGs agenda is partnership to achieve SDGs based on acooperation framework in all spheres development agenda.
Indonesia is facing a similar problem due to Covid-19 outbreak. It has taken a toll on the qualityof Indonesia education caused by the paradigm shift and attitude change as the result of migration fromthe offline learning approach to the online learning approach. In fact, the online learning approach is
not enough to fulfill essential study results than the offline learning approach. There are critiques anddebates over implementation of the online learning approach, from the teachers ability, students ability
to understand the lessons, and additional cost that is taken for internet access, especially for remote orouter parts of Indonesia. This article was focused on how partnership within public participation could
become adequate, effective, and ideal ways to tackle Covid-19 impact in the Indonesia educational
process.
Materials and Methods
This article was conducted with application of empirical legal research, focusing on the gap
between law in written and law in action/practice of education, it is commonly referred to qualitative
research. This article uses primary legal sources, and secondary legal sources that are supported withstatutory law approach, legal conceptual approach, and socio-legal facts approach.
Results and Discussion
Education is one of the important international issues, it is related with the placement of theright to education in the UDHR and ICESCR. This recognition reflects the UN members obligation to
fulfill and to ensure good and adequate quality of education. In recent years, many education problems
have been faced, especially after Covid-19 outbreak. The learning paradigm has been changed
drastically from offline to online approach, despite any pros and cons that raises, this article wasproposed to ensure that Covid-19 will not spread at school, with the obligations of everyone wearing
their mask, keeping the social distance and also getting their vaccine. It would be achieved with allparticipation in dealing with these obligations. In this context, there is a need to distribute masks tothose who don’t have it, remind or socialize people about the danger of Covid-19 and to never makepeople around them forget to keep their distance and lastly, everyone getting vaccinated.
Those ways could be implemented with partnership as the part of public participation, by
working together with people and by contributing in solving these problems, it could drive SDGs
achievement, with knowledge sharing and cooperation, promotion of sustainable technologies tostrengthen and empowering national capacity, enhance SDGs capacity, enhance policy coherence forsustainable development, respect national leadership to implement policies, enhance global partnership,
encourage effective partnership and further develop measurements of progress.

The Inequality of Water Distribution Households in Bogor CityINTRODUCTION
Bogor City has a population over than one million with 82.9% of them never having difficulties withsecuring clean water (according to the government survey in 2014). This research has done a survey toillustrate the current situation clearly. According to our survey for Bogor citizen, there are two main things
that are used for clean water sources, 70,4% uses PDAM, 21,5% wells, 10,3% both, the rest is the others.
[1]
PDAM (Perusahaan Daerah Air Minum) is the main governmental organization that runs clean water
distributing sector dedicated for all of Indonesia’s citizen. [2] The recent Indonesia COVID-19 lockdown
named PPKM (July - September) hampered the PDAM productivity of work resulting the poor responds
from PDAM. A city with 118.5 km2 has exceeded the population density ideal which is 8,985 people/km2.
This causes various problems. Firstly, the quality of water. Septic tanks become inseparable between
water pipes. More than 77% pipes are < 15 m length than their household septic tanks. This obviously
reduces the quality of water, explains why clients often complain about their water color and an
unpleasant smell. That will create long-term effects not only Bogor’s environment, but other places that
confront the same issues. The unreliability was made more apparent by the customer who use both wells
and PDAM. 23% of customers also encounter problems once a month or more. Furthermore, there areseveral areas where PDAM water pipes haven’t reached, durability of pipes aren’t great, extreme seasons.
Lastly, the cost of PDAM isn’t worth it. Most people see it as money wasted.
SOLUTIONS• Solutions that have been done:
1) Continuously expanding and improving distribution system. 2) Providing free water from PDAM inemergency. 3) Implementation of several programs that emphasize on the importance of clean water andsanitation. 4) Socialization about clean water and sanitation to the general public.
• Solution that could be done further:
1) Establish a Public-Private Partnership (PPP) in improving and expanding water pipes structure; 2)
Clearing and protecting the environment better from pollution to make wells a viable alternatives formany people. minimize the risk of natural disaster that could damage the pipes; including increase theamount of places/facilities to dispose garbage, widespread cleaner communal toilets, etc.; 3) Increasing
incentives on reducing pollution, protecting the environment, conserving water, improving regional
sanitation, etc.

2. Universitas Pendidikan Indonesia, Indonesia
Purpose and Background:
The purpose of this research is designing a prototype to filter the water so that the water can be reused, and made as
simple as possible to filter both water waste and well water that is problematic so that it can be made to meet household
needs. The background of this research is water problems which are one of the problems that are widely experienced invarious regions, the difficulty of clean water due to polluted water sources. The cause of dirty water in the river is thedisposal of industrial waste slaughter animals, factories, and household waste that is not processed first, so it is polluting
the river. If waste is not treated first it will lead to reduced availability of water, so it is necessary to solve the problem
for water waste treatment.
Materials and Methods:
The materials used to make Kindra filter are (1) Pipe 3 inch 70cm; (2) Water tank nut ½ inch; (3) External drat tight½ inch; (4) Hubcap drat 3 inch; (5) Plain hubcap 3 inch; (6) Glue pipe; (7) Large pebbles; (8) Small pebbles; (9) Sand;(10) Silica sands; (11) Black sands; (12) Palm fiber; (13) Foam; (14) Used bottle water 1 liter.
The methods for making this Kindra filter are; first make a sketch of the water filter's design, and make a hypothesis
about the most effective filter, filter A arrangement will be more efficient and maximal because the filter arrangement
is more systematic. After that create 2 filter tests with the bottle with different filter arrangements, filter ‘A’ (large
pebbles, silica sand, black sand, sand, small pebbles, and each layer is lined with palm fiber 1 cm), filter ‘B’ (large
pebbles, small pebbles, black sand, sand each layer coated with palm fiber 1 cm). The next step is to choose the type offilter to be created, filter to be selected filter ‘A’ because the result is better than filter B. Then, make a hole on the pipe
about 10 cm from under the pipe, then attach it to the tank. Arrange the media filter; large pebbles 10 cm, foam, small
pebbles 5 cm, silica sand 5 cm, sand 7.5 cm, black sand 7.5cm, sand 7.5 cm, gravel 3 cm, each layer is coated by 3 cm
palm fiber. After that the filtered water is ready to be accommodated and reused.

Result of this research Kindra filter successfully filters the water to be clearer and raises the pH, so that the water
waste can be reused. The filter arrangement used is the filter arrangement 'A', because in previous experiments filters'A' and 'B' both increased the pH of water waste from 6.8 to 7.3. But when viewed from the clarity of the water filter'A' is clearer than filter 'B'.
Significant pH differences occur due to the accumulation of impurities both from organic substances and nonorganic filter media will form layer biological. With the formation of this layer, in addition to the screening process
physics can also remove (impurities) bio-chemically. Filtration capability and efficiency can also work effectively inthe process of improving the physical quality of water and the chemical quality of water. When the surface temperatureof the water rises, the solubility of carbon dioxide will decrease so that the pH will rise and the water is alkaline (Astari,
et al., 2013).

Purpose and Background

1. Water quality in Ping River is below thewater standard.
2. Water quality is related to the catchment
site.
• The upstream spot (Doi Saket District)has the best quality, while the districtcloser to the city has the more inferior
quality• Chiang Mai city (Muang District) has
the worst water quality.
3. Our finding is correlated to the previous
studies showing the poorer quality of water
near the city.
4. Raise the campaign• Avoid dumping garbage into the water
system.
• Reduce using
herbicides
andfertilizers.
5. Treat the polluted water by filling theoxygen into the river

The Ping River is one of theheadstreams of the Chao Phraya River and themain river of Chiang Mai province. It was atrade route and has been of great importance toresidents and the surrounding ecosystem. The
faster the city grows; the more polluted water
is. Water monitoring should be done regularly
because when water quality is poor, it affects allof us. The purposes of this study are to evaluate
the physical, biological, and chemical quality ofwater from the Ping River and to compare thewater in the Ping River with the standard
quality.
Materials and Methods
1. Investigate the study site
2. Collect the sample and measured thephysical quality of the Ping River’s water
via temperature, transparency, and thechemical quality of water through dissolved
oxygen and pH by using GLOBE protocols.

Purpose and Background:
The purposes of this research are analyzing students’ knowledge about trash management and designing trash canthat could fulfill people need.
The background of this research is low people awareness about trash management directed to the limited numberof trashes can in public places. People find it hard to disguise each trash can for different type of trash since there is
not any clear instructions, while people have learned about trash management in school. As a part of curriculum,
Environmental Education or PLH help student to learn about environment which trash management also part of its
topic. Based from the previous research which conducted by Istiqomah, Suwondo & Firdaus (2020), it shows thatEnvironmental Education could forming student awareness about environment, especially with monolithic PLH
learning.
Materials and Methods:
Several materials that used to create ASHCAN are (1) used paint bucket; (2) paint; (3) paintbrush; (4) sandpaper;(5) spray guns. Questionnaire are used to collect data about students’ knowledge about trash management.
The methods for making ASHCAN are (1) design sketch for the trash can; (2) prepare a used bucket and rub
sandpaper on the outside of the bucket so that it does not arise when painted; (3) use a spray gun to paint the basecolor of the bucket using a spray gun to speed up the process; (4) after the paint is dry, immediately sketch the trashicons outside the bucket; (5) paint on the trash icons that have been drawn.
Results and Discussion
The research has surveyed in the form of questionnaires to 147 school students regarding trash management. For
the First question about students’ knowledge about trash management, it revealed that 100% of correspondents
responds that they know how to dump trash properly. For the second question, about 95.9% responds that they know
how to separate trash correctly, and most students answer “Take the strewn trash and throw it in the trash canaccording to the type of trash".
On the question number 3 about the act whenever they see trash strewn around, about 135 students answered thatthey can distinguish between organic and inorganic trash correctly. When student asked to give their opinion how tocreate clean environment, most of them give an opinion “do not throw garbage carelessly, and separate type of
garbage to be disposed of in its place”.
Based on the observation, it has been proven that people prefer to throw garbage on "ASHCAN". Moreover, people
who do not know the type of garbage, they dispose the trash while looking at the icons of trash which are drawn on
the surface of "ASHCAN". In conclusion, people know which type of garbage they need to dump into different trashbin, since there are trash icons on ASHCAN. The figure below showed the observation result by placing regular trash
bin and ASHCAN in public places for 15 minutes.

2. IPB University. Bogor, Indonesia
Purpose and Background:
The shift of the learning model from face-to-face between teachers and students to online learning
due to the pandemic through various learning media platforms is not something that can be directly
accepted, both by students and teachers as educators themselves. There are many changes in student
behavior that occur in the online learning process. Initially learning began in school and has now moved
into each student's home. Therefore, this research was conducted to find out if online learning affects
student behavior and what impact online learning will have on student behavior.
Material and Methods:
The method used in this study is a quantitative method. Data were collected through a direct survey
using a questionnaire. There are several questions asked in the questionnaire. Questions in the questionnaire
include extracting data and information on the impact of online schools on students' daily lives. The
question asked in the questionnaire is how online learning affects students' daily lives as students, startingfrom sleep patterns, study patterns, grades, student socialization with friends, and student motivation.
Research respondents consisted of 123 people who were students of SMA Kornita Class X, XI, and XII.
Results and Discussion:

Student daily life that are most affected by online

Furthermore, there is the achievement of scoresas a variable that changes in changes in student behavior (52.8%). Furthermore, students' learning
motivation (52%). Sleep pattern variable is the sector that is least affected by this online learning (47.2%).
The next data shows how the impact of changes in students' daily lives due to online learning so far. Around
66.7% of the 123 students felt the negative impact of online learning, 21.1% felt that online learning had apositive impact, and the remaining 12.2% felt that online learning did not have any impact on them.

The conclusion that can be drawn from the data above is that online
learning has a negative impact on most students. but there are some students
who feel that learning has a positive impact. Many factors cause students to feel
negative and positive impacts. The most important factor is the process of
sudden change so that students find it difficult to adapt to change. For thisreason, several existing solutions must be immediately implemented by teachersand students in order to continue to adapt to current conditions.

Be Creative in the Pandemic Era : Detect Types of Snake Bites
with Augmented Reality
Siti Ramadina Goethe K., Muchammad Zakky A., Sari Narulita,
1. SMA Negeri 1 Bandung, Indonesia
Purpose and Background : During this pandemic, there are many things that we are able to do to fill ourspare time. Utilizing free time to be creative in making augmented reality-(AR)-based applications is one
issue that may change the way we see our world. In addition to having the ability to develop creativity
and skill, the AR technology may also be beneficial to the surrounding people, such as in this case to
avoid unwanted things regarding venomous snakes. The application of AR in detection of venomous andnon-venomous snakes and in guiding first aids after being bitten by a snake is very important, considering
the number of snakebites in Indonesia up to one hundred thirty thousand per year with an unknown
number of deaths.1 Improper handling resulted in the loss of lives that should have been avoided.
Therefore, a required associate application which will share information regarding venomous and nonvenomous snakes as well as education first aid for snake bites, can use an application named ARORAY
which is based on augmented reality technology.
Materials and Methods: Teamwork and general software are needed to support the activities of making
this application. Among these software are:1. 3D designer, using Blender v2.76.
2. 2D designer, using Adobe Illustrator CC 2018.
3. Software engine : version unity 2019.2
4. Social media app, for communication between group members.
We utilized the method of linear sequential model (in software development).2 Application design can bemade in the form of a storyboard which is entirely the development of collaborative ideas. Then
programming is done to translate the design into programming languages (Java and JavaScript), that canbe interpreted by the machine. Once the application has been built, the next steps are testing anddebugging processes to examine for errors that may exist and to affirm that the desired results areachieved. Within the end, software maintenance is still carried out before and after the software islaunched.2
Results and Discussion
To use the application, users need to select an AR snake
marker card. Then the selected snake will be visualized. The
first snake is a king cobra, which is a venomous snake. The
second one is a reticulated python (non-venomous snake).
While the coconut forest picture AR marker card will display
a 3D animation of the person bitten by a snake and a 'start'menu that contains first aid steps that must be carried out.

Purpose and BackgroundAs there are reported cases about patients with poisoning from consumption of; Alocasia
macrorrhizos Schott, Phytolacca americana, and Datura metel L., due to their confusion with the similarmorphological features of those of its edible counterparts which are Colocasia gigantea Hook.f., Talinum
paniculatum and Brugmansia suaveolens subsequently. This study sets out to use DNA Barcode to help
distinguish these three pairs of toxic plants from edible plants having similar morphology features,
determine the most suitable DNA marker, and to contribute as a reference for further research of theseplants.
Materials and Methods
The DNA of sample plants were extracted by C-tab protocol and replicated for specific regions:rbcL, matK472, and ITS2, by PCR. The qualification control of DNA was examined by gel electrophoresis
technique and NanoDrop Spectrophotometer, then all DNA samples were sent to a gene sequencing
company to determine the nucleic acid sequences. Finally, DNA sequences were analyzed and constructed
into phylogenetic trees by using Chromas and MEGA-X program.
Results and Discussion
All phylogenetic trees show the evolutionary relationship between toxic plants andmorphologically similar edible plants, and verify that these toxic plants and edible plants can be
distinguished by using DNA Barcode from rbcL, matK472, and ITS2 regions. Moreover, the result showsthat matK472 region is the most suitable DNA marker for the identification of these plants.

Adsorptive removal of pharmaceutical products using novel
adsorbent based on core-shell CeO2@SiO2 nanoparticles
synthesized from rice husk.
Khanh Linh Vu and Viet Huy Dang
High School of Education Sciences - VNU-

Purpose and Background :The pharmaceutical resistance that is a serious problem. One of the reasons forpharmaceutical resistance is the pharmaceutical residual in the water in the environment.
Therefore, the removal of pharmaceutical residual from aqueous solution is very
important.
-Materials and Methods :There are different methods can be used for the removal of pharmaceutical residual.
Among them adsorption is one of the most effective methods and suitable for developing
countries such as Viet nam using agricultural sub- product like rice husk. CeO2 can beused to coat the nanosilica rice husk to produce the new materials is called as core shell
CeO2@SiO2 materials with high performance for pollutant removal. Amoxicillin(AMX) and Diclofenac (DCF) are widely used pharmaceutical products and high demand resistance.
Therefore, I focus on removal of AMX and DCF by using core shell CeO2@SiO2 nanoparticle. This
project has 4 objectives : firstly is synthesis and characterization of core-shell CeO2@SiO2 nanoparticles
based on rice husk, second is adsorptive removal of AMX and DCF using CeO2@SiO2 nanoparticles,
third is adsorption mechanisms of AMX and DCF using CeO2@SiO2 nanoparticles and finally isapplication potential of CeO2@SiO2 nanoparticles for water real sample.
-

Results and Discussion :In order to complete the objectives, the first experiment is thesynthesis of nano CeO2@SiO2 from rice husk. The CeO2@SiO2
nanoparticles are characterized by the X-Ray diffraction, FTIR
infrared spectrum, TEM image capture and BET specific surface
area. Based on XRD, TEM, FTIR, and BET methods, I confirm
that CeO2@SiO2 nano successful synthesis in laboratory. The
effective conditions for Amoxicillin (AMX) and Diclofenac(DCF) removal using CeO2@SiO2 were studied. Optimum
adsorption time is 120 minute for AMX and 60 minutes for DCF.
The pH 3 was selected for AMX and pH 5 was the best for DCF removal. The best adsorbent dosages
were 5 mg/ml and 20 mg/ml for AMX and DCF respectively. The removal of AMX and DCF using
CeO2@SiO2 reached greater than 90 % under optimum conditions. This results indicate that the core-shell
CeO2@SiO2 nanoparticles synthesized from rice husk is a new and novel adsorbent for removal ofpharmaceutical residues in water environment.

Purpose and BackgroundThe existence of fossil fuels are hazardous to our environment, burning fossil fuels emits anumber of air pollutants that are harmful to the environment and also public health, and as times go by,
it will be decreased. From there we want to make an environmentally friendly and renewable fuel, we
have studied many journals and found that microalgae convert solar radiation energy into chemicalenergy via photosynthesis. It represent alternative and competitive source of biomass. And from there
we can make the purpose of this project which are, produce a biomass from algae oil and decrease air
pollution and dependence of fossil energy.
Materials and Method
Materials that we use in our project are:Phytoplankton starter then the F / 2 XWARP Fertilizer that is given once a week to thealgae cultivation, and there is an aquarium as a place for cultivation, actually you can also use
a pond or used mineral water bottles, aerators and 10-20 watt lamps which are components that
support cultivation, and the last but not least is salt used to make water for cultivation and alsomethanol, alcohol, and sodium hydroxide.
Method that we use in our project is:Transesterification Reaction
Biodiesel is made through a chemical process called transesterification in which
glycerine is separated from vegetable oils. This process produces two products, namely methyl
esters (biodiesel) and glycerine which is a by-product.
Step 1, mixing alcohol for reaction with a catalyst, a strong base such as NaOH
The catalyst is made by mixing methanol(CH3OH) and a strong base such as sodiumhydroxide(NaOH). During preparation, NaOH breaks down into Na+ and OH- ions. OHabstracts hydrogen from methanol to form water and leaves CH3O- available for reaction.
When the OH- ion reacts with the H+ ion, it reacts to form water. Water will increase the chanceof side reactions with free fatty acids (not triglycerides) to form soap, an undesirable reaction.
Step 2, React with fatty acids so that a transesterification reaction occurs.
After the catalyst is prepared, the triglyceride will react with 3 moles of methanol, so
excess methanol must be used in the reaction to ensure a complete reaction. Three carbons
bonded to hydrogen react with OH- ions to form glycerine, while the CH3 group reacts withfree fatty acids to form fatty acid methyl esters.
Results and Discussion
Top layer: hexane + FAME, triglyceride residue, FFA
Bottom layer : mixture of methanol, water, triglyceride residue, FFA andglycerol.
Microalgae are single-cell organisms that convert solar radiationenergy into chemical energy via photosynthesis. Algae possess very highphotosynthetic efficiency, can fast build biomass.
With transesterification method the dry green algae can change into
biomass. it just need 3 material, which are methanol, Sodium hydroxide, andhexane52

The Impact of Inadequate Tuned Mass Damper Design
CHOU, YUN-WEI / CHANG, CHEN-YU
Jingmei Girls High School, Taiwan, Taipei
Purpose and Background
A TMD is a damping device that can reduce the vibration of the structure. The inertial force of the TMD massabates the resonant vibration of the structure by dissipating its energy. While technology nowadays still cannot help
forecast earthquakes and issue alerts long before it happens, so further research is necessary to be conducted byadjusting the damping parameters in hope of finding a better design to reduce the risks and damage brought about by
earthquakes.
Materials and Methods
In the purpose of devising parameters of TMD and observing which works more efficiently, the experiment was
divided into three parts: in the light of the professor, according to the essay, and randomly input data to investigate
the damper design with structure mass(N-s^2/m), structure stiffness(N/m), damper mass(N-s^2/m), damper
stiffness(N/s), damper coefficient(N-s/m) to simulate and make graphs.
Results and Discussion
In these graphs, the x-axis refers to the frequency(rad/sec) and the y-axis refers to the transmissibility. The redline is the original effect after the architecture suffered a sine wave. It shows the maximum vibration of thearchitecture at the frequency of 5.3rad/sec. On the contrary, the blue line means the effect with the damper, thevibration of the architecture is obviously descending. The peak means the max reaction of the structure. The moredifference in the peak between the red line and the blue line, the more effective it is. The figures show that if the data
was randomly inputted, the damper design may be ineffective.
The conclusion is as follows:
1. When the frequency of earthquakes is similar to that of the architecture, the damper will be more effective.
2. If the mass of the damper is heavier than the architecture, it may be ineffective even cause a backfire.
3. Many factors would cause the architecture to vibrate so there is still some room for negotiation.
Figures

The trend of the blue line is stable
and the peaks of the red line andblue line are greatly different, so
this design is effective.

The trend of the blue line is unstable
and the peaks of the red line andblue line are close, so this design
is ineffective.

The trend of the blue line is unstable
and the peak of the blue line ishigher than the peak of the
red line, so this design is ineffective.

PURPOSE AND BACKGROUND

The electricity crisis is one of the major problems faced by the Indonesian state. The
increase in electricity needs is not offset by the increase in generating capacity resulting in a
deficit in electrical energy. This can be seen from the national electricity electrification ratio
which currently only reaches 80% (Anonim, 2014) even though the electrification ratio ofneighboring countries such as Malaysia and Vietnam is already above 90%. Singapore's
electrification ratio has reached 100%. This bio-battery has the same components as a regular
Fuel Cell, covering the cathodic and anodic bodies. Material is oxidized by microorganisms
and produces electrons and protons (Aulenta, 2007). Electrons are transferred to the cathodebody via external circuits and protons are transferred through membranes. Electrons andprotons are combined with oxygen in the cathodic body to form water (Amos, 2008).
The objectives of this study are as follows (1) Utilizing algae (Chlorella sp) as analternative source of electricity that is environmentally friendly and sustainable (can continue
to be produced) as well as one solution to solve the problem of blooming algae. (2) Determine
the voltage generated from the bio-battery created.
II.

MATERIAL AND METHODS

Researchers will also conduct experiments on algae in the laboratory to know more about
what materials are needed for this Bio-Battery to function perfectly and also what can be thecause of the failure factor in this experiment.
Data collection is done from the literature that researchers get online and notebooks, inthe form of journals about Chlorella sp and galvanic cells. And if necessary, field observations
will be made.
III.

RESULT AND DISCUSSION

The resulting voltage value is different for each electrode usage. In the use of Zn//Cu
electrodes, the resulting voltage is 0.937 volts. While the use of Zn//Carbon electrodes has abetter voltage value of 1,083 volts.
When two conductors, such as Cu-Zn and C-Zn, are connected through a solution withan unbalanced concentration of positive and negative charge carriers, one type of charge carrier
will be collected on one conductor and the other will be collected on the other conductor sothat at both ends of the conductor there is a potential difference. This system is known as a
voltaic cell.

The Motion of Meteors in the Atmosphere
Chung, Wei-Hsuan
Taichung Girls' Senior High School, Taiwan
Purpose and Background
Discussing the motion of meteors in the atmosphere is not a new thing. However, I found that two studies using thesame observation method but had different results: one of the studies is from Taitung Girls' Senior High School
students Lin, Chen, and Fu (2011), the other is from Wang (2018). And this study is to compare their researches andinvestigate what makes their results different.
Materials and Methods
In this study, I sort the differences and the similarities in the methods of the two studies, analyzing how the differences
affect their results and list some factors affecting the meteor motion that were pointed out in some studies.
Results and Discussion
The two studies used the same video observation stations and the software to analyze their pictures, but they useddifferent ways to locate the meteors and adopted different amounts of meteors to analyze. In the study by Lin etal.(2011), the results showed that the velocity of meteor was constant. By contrast, in the other, the results showed thatthe horizontal velocity changed with time and the vertical velocity was constant.
I tried to fit the data used in the study by Lin et al.(2011) withthe coefficient of determination (𝑅 2) was much close to 1
(Figure 1). Due to the results, I thought that what kind of theregression they adopted was the main reason to make theirresults different and whether the horizontal velocity of meteor

Purpose and Background:
The purpose of this research is to create a tool to maintain the cleanliness of the fishpond effectively in termsof time and water consumption and to increase the oxygen saturation of the fishpond’s water. The background is thatthe vision as a National Adiwiyata School, leads the SMAN 1 Lembang to create the environment who embrace threeelement, earth, air, and water in a harmony. Water element represented in the form of fish pond which provide a freshand relax environment as well as supporting the students in Biology learning. Preserving habitat needs clean and sustain
environment. However, the maintenance of the fishpond is challenging since it needs lots of water, additional support
staffs as well as time consuming. All of this problem leads us to filter the pond using the tool that we made.
Materials and Methods:
We have a few materials and tools for the research. And it will be divided in 3 groups: Tool, Filter box material, andMaterials. For the materials or filters we have zeolite stone, palm fiber, foam filter, plastic ball, active carbon, blacksand. For the tool we have pipe ½ inch, pipe connector ½ inch, water pump machine. For the Filter Box we have glassparts, glass glue, cutter, black marker, ruler.
To get the final result, we need to make a glass box for the fishpond. Glue the glass parts so it will become a glassbox. Make a hole at the middle of the glass box so the water can flow back to its water source. Place all 6 of the water
filters to the mini box that has been provided. Attach the pipe with the water pump machine.
Place the water pump machine in the water. Test the water pump machine, if it succeeded to pump the water then it
only needs to evenly and nicely flows the water from the mini box to another mini box. There are 2 types of triple filtersthat will be tested. There is filter A (palm fiber, foam, and black sand) and filter B (plastic ball, zeolite stone, and active
carbon). There are going to be 3 types of fish that will be researched (black fish, orange fish, and white fish). The
oxygen saturation of the fishpond will be researched and investigated through the breathing rate of fish per minute. We
are going to see the oxygen saturation from how many times the fish will take a breath. We are going to count how
many times the fishes took a breath in a minute. The hypothesis is that type B is more likely to be the better Filter thantype A. Because the material is more expensive and the materials almost fill the whole mini box
Results and Discussion
The result showed that filter type A is more effective on cleaning the water and increasing the oxygen saturation
than type B. It is because the filters on type A contains better ingredients to increase the oxygen saturation on a fishpond.
From the result turns out, there is a difference on the amount of breath the fishes took in a minute. According to Putra,
Lisdiana & Pribadi (2014), a fish breath 50-150 per minute, based on the temperature of the habitat. The higher thetemperature, the higher as well the fish will take a breath. On this research, the light intensity improves because thewater is clearer, that’s why the temperature is increasing. Based on the table below, it’s proven that type A is more
effective on increasing the oxygen saturation. The table below will feature how many times the fish will take a breath
per minute on day one to three at 2 types of filters.

TITLE: CLAY-SAWDUST COMPOSITE WATER FILTER SYSTEM EXPLAINED
Nguyen Phuong Thuy
The Olympia Schools, Vietnam
Purpose and Background: AFFORDABLE AND PORTABLE SOLUTION“According to the latest available figures, an estimated 2.5 billion people lack improved sanitation facilities,
and nearly one billion people do not have access to safe drinking water.” (WHO 2009) Water related diseases, suchas diarrhea, cholera, and malaria are the leading cause of death, especially with children, in many developing nations.
In Central Vietnam, around August, September and October is the raining season. Heavy storms and long last rain
destroy a lot of water facilities and cut off the residents to essential water access.
There is a huge demand for a water treatment system that is portable, affordable, and user-friendly to tackle
this problem. Thus, clay-sawdust water filter system, composed by only cheap locally available materials and proventhe ability to purify water, is one of the most suitable method.
Materials and Methods: HOW THE SYSTEM IS CREATED
The main raw materials used for the production of the filter are plastic
bucket, water tap, clay, water, and various proportions of burnout materials (sawdustin this case was added to increase small pores in the ceramic material when fired,thus increase porosity). The sawdust and clay then mixed together with water to form
a flexible compounds. The clay is molded then fired in a kiln for furnace.
Once the ceramic is done, arrange the parts as shown beside.
Results and Discussion: STATISTICS AND POTENTIAL IMPROVEMENTS
The result table is from a research made by Faculty of Engineering, University of Nigeria, Nsukka, in which
they mix 5%, 10%, 20%, 30%, 40% of sawdust to a fixed amount of clay (6kg); designated as filter A, B, C, D, andE respectively.
Filtration results for storm water

Quality parameters of raw water used in the study

Note: SS: Suspended solids concentration, BOD: Biochemical oxygen demand, TC: Total bacterial count
The technical advantage of clay filters is that they do not significantly change water taste nor temperature.
Compares to other methods, they do reduce turbidity. They are also stable structures with only one moving part (thetap) and function without the need of any external energy source. Their durability is high: with proper care andmaintenance, they can be used for years. Crucially, this clay composite system works well not only with sawdust,
but also with other materials like coffe-grounds, depends on the local supply. This increase the practicality of the
products for different areas, and therefore able to help more people.

Oil and Grease precipitation process from canteen’s wastewater by
Chitosan and transforming sludge into compost.
Miss Jinjuta Luanglertpaiboon
Miss Chanidapa Luanglertpaiboon
Chulalongkorn University Demonstration Secondary School
Purpose and BackgroundNowadays, water pollution is still a problem getting a lot of attention because it affects us both
directly and indirectly. Of course, consumption is one of the causes of polluted water, especially fromcooking that has not been treated to the standard before being released into natural water and effluent
from the washing equipment. This polluted water consist of organic substances, and chemicals Oils, andfats which are mainly discussed here. Oils and fats are organic substances that are less dense than water,
so they float on top so it obstructs the distribution of oxygen into the water. Then, it causes a bad smell
and low water quality. It’s also a major problem in the polluted water treatment process as it can cause
clogging of sewer pipes. Currently, chitosan is widely used to trap fat in polluted water. Yet the use of
chitosan to filter the water is still has a vulnerability, that is, the sludge formed by the coagulation of
chitosan and fats, which do not have a way to be 100% recycled back to nature. Therefore, this project
found the problem and created this project by bringing chitosan to filter water to reduce pollution
problems, and also bring sediment from the filtered water with chitosan for fermentation. The resulting
fertilizer had a good effect on plants growth as well.
The purposes of this project are 1. To reduce the problem of seafood waste and water pollution 2.To
study the efficiency and results of water purification with chitosan. 3. To bring the sediment from water
filtration with chitosan to develop into fertilizer.
Materials and Methods
The project processis divided into two main parts: First process, Chitosan fat precipitation experiment.
The materials are water, oil, chitosan, calcium carbonate powder, and dishwashing liquid. There were 3
experiments on factors affecting precipitation that is stirring speed, the amount of calcium carbonate
powder, the difference between the polluted water with and without the dishwashing liquid. For thesecond process, bringing the sludge to make compost. The materials are crab claw leaves, n. animal
manure, coconut pulp, and sediment obtained from fat trapping with chitosan.
The steps are: bring 250 g. of manure, natural scraps (crab Claw leaves and coconut pulp) 150 g. mixed
with sediment obtained from filtered water 1 , 1/2 , 2 teaspoon, respectively, to compare the efficiency of
the fertilizer by bringing to plant that is chilli and spring onions.
Results and Discussion
The results of the fat precipitation experiment from chitosan were obtained:
1. The speed of the rotation of the most efficient stirring in 100,200ml of water is 120 rpm. But in500ml
120,180 rpm both the best stirring speed, comparing the clear turbidity of the water and the amount of fat
floating on the water.
2. The amount of calcium carbonate powder, that is, the best amount of powder that can accelerate
sedimentation is 1/2 tablespoon per 100 ml, measured by clearness and sediment volume. after setting it
for 5 minutes.
3. Lastly, the difference between precipitation of chitosan in polluted water with and without dishwashingliquid. The result of the experiment was that the polluted water with dishwashing liquid was clearer andslightly more precipitated.
The fertilization still in the process of operation and follow-up on the results of the experiment.
According to reserch by KKU SCIENCE JOURNAL, Every quantity of Chitosan can increase efficiencyof plant growth ,so we predict our fertilizer will beneficial to plants.

Reo Suzuki
Ichikawa High school, Japan
Purpose and Background
Reducing the amount of waste is essential for reducing environmental stress and achieve SDGs. The disposable hot
pad is a popular portable heating material in Japan. The disposable hot pad produces heat from the oxidization ofiron. The pad is used during the winter season and disposed after one use. Sasaki [1] reported the recycling of usedpads as material for water purification. In the report, releasing iron ions from the purifier made from the used pad
was essential for improving water. The report suggested ionization effect similar to the Voltaic battery mechanism isrelated. In this research, the effect of the ratio of iron and carbon powder on the ionization of iron was analyzed.
Materials and Methods
Material: Iron powder, carbon, micro-pipettor, 50 ml tube, 2.5 ml tube, paper towel, water, iron ion measuring
instrument, electronic scale, beaker, rubber stopper, spatula, pelletizer, medicine wrapping paper.
Method: Mix iron powder with carbon with the following ratio. Iron concentration at 100 percent, 95percent, 90
percent, and 85 percent, respectively. Add approximately 400 micro little of water to 1.5 gram powder. Those
powders were mixed well using a spatula. The mixture was applied inside the pelletizer and pressed to make a pellet.
Those pellets were soaked into 50 ml of pure water. The iron ion concentration was measured at 10, 30, 60, and 120
minutes after soaking using phenanthroline absorption spectrophotometry (Hanna Instruments, Tokyo).
Results and Discussion
Iron concentration in the water increased after soaking pellets according to the duration after the soak. However, theincreasing speeds of the iron concentrations differed among treatments. Pellets with 90 percent of iron powder emited
the most iron ion(Fig.1).

Figure1. The iron and carbon mixed pellets with a different ratio, 85%, 90%, 95%, and 100% iron, were soaked into
pure water. Ionized iron concentrations were determined with phenanthroline absorption spectrophotometry.
