Published: December 2021

Abstract
In this research work several high rise buildings were analyzed using CSI ETABS under the influence of the response spectrum analysis over it. Several different shaped high rise buildings such as H shaped, O shaped and C shaped buildings were taken into consideration for carrying out the research work. All three shaped buildings were of different storey that is of 12 storey and of 16 storey. For proper seismic analysis of all the above discussed buildings, response spectrum method of seismic analysis were taken into consideration. The results of all the buildings for response spectrum analysis were quite different from one another and it was found that the H-shaped building showed better results as compared to the other shaped buildings. It was also seen that the 12 storey building results were quite impressive as compared to the results of the 16 storey building. With the transference of heavy mass, very little effect was seen in latera sway i.e. variation in maximum displacement was negligible. Again, for 16 storey building, maximum displacement was found in the case L-Shaped 16 storey building with the value of 87.804 mm. Again, the transference of heavy masses had a minimal effect on total quantity and cost of the 16 Storey building. In the gist, it was concluded that, bending moments and shear forces were increased from 1.17% to 1.84%. Maximum variation in B.M and S.F. can be seen in O-shaped Building. L-shaped Building produces maximum displacement from all the three irregular shapes i.e. H-shape, L-shaped and O-shaped.

Authors: Manmeet Kaur 
Published: December 2021

Abstract
Air quality Index (AQI) is a tool which is implemented to assess the qualitative and quantitative status of air pollutants. Four distinctive pollutants; PM10, PM2.5, SO2 and NO2 were used to compare the prevailing ambient air quality in the study region-Ludhiana, the industrial city in the north Indian state of Punjab. The AQI for Ludhiana has been compared and, the ambient air quality data for the same has been obtained for Punjab Agricultural University, Ludhiana from Central Pollution Control Board (CPCB). The data has been compared for fifteen days before and after the lockdown amid COVID-19. Air quality information uncovers that during lockdown period PM10 and PM2.5 levels were decreased by around 35 to 40%, which might be clarified as conceivable decrease from production sector, transportation, and residue. AQI of Ludhiana revealed that the primary reason for the poor air quality is P.M 10 and P.M 2.5 which significantly reduced to around 10 to 35 percent during pandemic lockdown.

Abstract
Urban stormwater that flows through all the manmade structures contains high levels of BOD TSS, orthophosphate, surfactants etc. It raises concerns of water quality in the receiving natural water courses. Bio-retention is one of the prominent methods of stormwater management for the removal of contaminants from stormwater. In this esxperimental study, a column containing mulch, blast furnace slag, sand, silt etc. was used to assess the removal of suspended solids and nutrients (nitrate and phosphate) from stormwater. The tests were conducted with a flow through period of 3, 7 and 15 days. Removal efficiency of 80% total suspended solids for 15 day, 60% nitrate for 7 days and 70% phosphorous for 3 and 7 days was observed through the column. pH variation was found to be insignificant in the range of 6-7.5.

AbstractIntercropping with peanuts was reported to increase yield of cereal crops. The objective of this study was to examine the effect of peanut-intercropping and organic waste application on some soil chemical characteristics and red-rice yield under aerobic irrigation systems. The experiment was conducted from May to August 2020 in West Lombok (Indonesia), under Split Plot design, testing two factors, namely intercropping (T1=monocropped rice; T2=rice+peanut intercropping) in the main plots, and organic waste application (L0=without organic waste, L1=application of rice husk, L2=rice husk ash, L3=rice husk ash and cattle manure) in the subplots. Results showed that intercropping did not affect soil chemical properties but it significantly increased number of panicles and filled-grains, 100 grain weight, and grain yield of red rice per clump (31.27 g/clump under monocrop and 41.50 g/clump under intercropping with peanut). In contrast, organic waste application significantly influenced soil chemical characteristics and red-rice yield (the highest yield of 43.52 g/clump under L3). The significant interaction between factors on 100 grain weight indicated that the highest weight (2.89 g) was on intercropped red-rice under L3 treatment and the lowest one (2.18 g) was on monocropped red-rice under L2 treatment.

Abstract
The objective of this study was to evaluate the effect of organic waste application on some soil physical properties, growth and yield of red rice between conventional and aerobic irrigation systems on permanent raised-beds. The experiment was carried out in May to August 2020, under Split Plot design with two factors namely techniques of rice cultivation (conventional, T1; aerobic irrigation system, T2) as main plots, and organic wastes (L0=without organic waste, L1=rice husk, L2=rice husk ash, L3=rice husk ash and cattle manure) as the subplots. Results indicated that both treatment factors affected some physical properties of the soil, growth, and yield of red rice. Some variables showed significant interaction namely soil bulk density, red-rice height, leaf number and dry straw weight. Changing rice cultivation technique from conventional to aerobic irrigation system significantly reduced soil bulk density, especially under application of rice husk ash together with cattle manure or without cattle manure, resulting in the highest red rice grain yield of 37.78 g/clump whereas under conventional without organic wastes, grain yield was only 21.27 g/clump. On average, changing from conventional technique to aerobic irrigation system could increase red rice grain yield by 40.13%.

Abstract
Wild cassava (Manihot glaziovii Muell. Arg) is one of the varieties of cassava that contains toxic compounds cyanogenic glucosides, which cause unmarketable food products more suitable to be processed into bioethanol. This wild cassava plant produces tubers four times in weight compared to that of ordinary cassava, and the flesh contains about 40–70% starch by dry weight. This study aimed to determine the effect of the microbial types and fermentation times on bioethanol production from M. glaziovii Muell. Arg crude starch and to determine the type of microbes and fermentation time that can produce the highest bioethanol product from M. glaziovii Muell. Arg crude starch. This study consists of two factors using a factorial randomized block design (RBD). The first factor was the type of microbe which consists of 2 different microbes, namely R5I3 isolates and Saccharomyces cerevisiae ATCC 9763. The second factor was the fermentation time which consists of 4 levels, namely 3, 4, 5 and 6 days. The observed parameters were total dissolved solids value, pH value, reducing sugar content, and ethanol content. The data obtained were analyzed using analysis of variance (ANOVA) and continued with Tukey’s HSD post hoc tests. The results showed that fermentation using R5I3 isolates with a fermentation time of 5 days was the best treatment to obtain a maximum ethanol of 21.64±3.03 g/L, with a final pH value of 4.70±0.14, total dissolved solids 4.10±0.14°Brix and reducing sugar content of 0.91±0.02 g/L. Therefore, the new isolate R513 was highly potential for producing bioethanol from wild cassava crude starch.

Abstract
Amylase has an important role in biotechnology development and occupies an important position in the world enzyme market, as a biocatalyst in various industrial fields. This study has the goal to find microbial isolates that have the ability to produce amylase enzymes. The study was conducted in two stages, namely: 1) Isolation and selection of microbes that can produce amylase enzymes using starch as substrate, was incubated for 4-7 days at 30°C. Microbial isolates that can produce amylase enzymes are characterized by the presence of clear zones around the colony after the addition of an iodine solution of 1% in the overgrown media of microbes, 2) Test the activity of amylase enzymes using a dinitrosalicylic acid reagent test. The activity of the amylase enzyme is determined by measurement using a spectrophotometer at a wavelength of 540 nm. The sample used comprised of 7 types of ragi tape and 2 samples from cassava tape that has been fermented for 5-7 days. The results obtained in the first stage were 65 microbial isolates, 16 of which had clear zones, consisting of 7 isolates from ragi tape samples and 9 isolates from cassava tape samples. In the enzyme activity test, there are several isolates that have the potential to produce amylase enzymes, these include R5I4 (0.897 ± 0.018 U/mL), R2I5.1 (0.814 ± 0.011 U/mL), R5I3 (0.727 ± 0,042 U/mL) (derived from cassava ragi tape samples) and T2I2.2 (0.812 ± 0.013 U/mL), T2I6.1 (0.817 ± 0.010 U/mL), T2I2.1 (0.735 ± 0.023 U/mL), T1I4 (0.755 ± 0.020 U/mL) (derived from cassava tape samples). The isolate with the highest enzyme activity is the R5I4 which has the value enzyme activity of 0.897 ± 0.018 U/mL and with a fairly high or moderate category, while the lowest enzyme activity is the T1I1.1 isolate of 0.284 ± 0.020 U/mL.

Published: December 2021

Abstract
Anurans are important organisms as components of faunal community structure in ecosystems because of their roles as secondary and tertiary consumers in food webs. Anurans are opportunistic organisms that will consume any resources in their habitat. In this study, we dissected thirty-nine specimens of anurans from Museum Universitas Mataram (MUM) reference collection, it consists by three endemic (Ingerophrynus biporcatus, Limnonectes dammarmani and L. kadarsani) and one introduced species (Duttaphrynus melanostictus) of anurans. These reference collections were collected by authors during herpetofauna survey at Pusuk Forest, western Lombok in 2018. Based on stomach content analysis, both endemic and introduced anurans are generalist arthropod predators where hymenoptera, coleoptera, orthoptera and chilopoda are the most important food. In this study, we found positive correlations between body size and dietary niche breadth in which each anuran species has a high overlap of dietary niches. Anurans with large body size have a variety of prey than the small one.

Abstract
The Final Disposal Site (TPA) is where waste is disposed of at the end of its life cycle. The contamination of groundwater and surface water caused by leachate is one type of pollution generated by TPA. The goal of this research is to determine the level of groundwater and surface water pollution, as well as the correlation of leachate to groundwater and surface water in West Lombok’s Final Disposal Site, which is located in Kebon Kongok Hamlet, Suka Makmur Village, Gerung District. The analysis method utilized in this research is the pollution index method and the analysis which consists of a correlation test. The results of the analysis of groundwater pollution levels from samples of resident wells were classified as adequate condition, lightly polluted, and moderate polluted. Meanwhile, surface water is classified as moderately polluted. The results of the TSS correlation test analysis on groundwater turbidity have a positive direction and a strong correlation with a value of 0.643. The results of leachate TSS analysis against surface water TSS have a positive direction and a moderate correlation with a value of 0.357 as well as the COD of leachate against COD of surface water with a value of 0.257. The results of the analysis of leachate BOD to surface water BOD indicate that there is a moderate correlation with a value of 0.475. This is in line with the pollutant index which has a moderate polluted value. Referring to the findings, it is recommended that the urgency of zero waste should be implemented by all parties, not only the government but also all levels of society.

Abstract
Corn and sugarcane-base bioethanol dominantly contributes to the 25 billion gallons of bioethanol worldwide. Recent researches focused on the potential microbes and biomasses for optimum production. This study is, therefore, aimed to screen the bioethanol generating yeast strains of Biotechnology Culture Collection (BTCC), isolated from chocolate fermentation in several medium containing various carbon sources. A total of 72 yeast strains were grown in the media containing sugarcane juice, sorghum juice, and molasses, which served as carbon sources. Based on 26S rDNA gene analysis, these species were included in 9 genera, encompassing Saccharomyces (63.9%), Hanseniaspora (9.7%), Candida (0.7%), Torulaspora (0.4%), Pichia (0.8%), Issatchenkia (0.1%), Wickerhamomyces (0.3%), Metschnikowia (0.1%), and Rhodotorula (0.1%). Therefore, spectrophotometer UV-Vis was used to analyze cell growth, while the fermentation products (sugars and ethanol) were evaluated using the HPLC, and about 70 strains produced bioethanol. The highest yields were obtained during fermentation, using sugarcane juice, molasses, molasses waste, and sorghum juice, at concentrations of 43, 50, and 7 g/L, respectively. Furthermore, the Saccharomyces cerevisiae strain were the most significant producers, as the genus was able to generate various concentrations from several carbon sources. However, the only genus without the ability to yield any related products during fermentation was Pichia (0.8%). Based on these results, it is necessary to further develop the yeast strains from chocolate fermentation, due to the potential for bioethanol production from biomasses.

Published: December 2021

Abstract
In this study, the custom-built pipette-tip solid phase extraction (PT-SPE), was used for pre-concentrating the selenium (Se) in green tea samples. The PT-SPE was prepared using a pipette tip and C18 as the adsorbent that was placed between glass wool. This method afforded several advantages in terms of efficiency of extraction time (8 min), sample (2 mL), and solvent (1 mL) volumes with less wastage of solvent. Under optimal conditions of extraction, this method yielded good linearity (r2=0.998) for the Se calibration curve and good limit of detection (0.2 μg/L) and quantification (0.6 μg/L). The standard addition method was used to remove the matrix effect. The recovery percentages of tea samples spiked with different Se concentrations ranged from 97.7 to 106.0%, indicating that the proposed method would be suitable for the determination of Se in green tea samples.

Abstract
Algae are a photosynthetic organism, affordable and naturally rich in nutrients and a valuable source of bioactive substances such as natural pigments. Bulung sangu (Gracilaria sp.) is red macroalgae that wildly grows and distributes in Bali. The aim of this work was to optimize the solvent to extract the chlorophyll content of Bulung sangu. The pigment extraction was carried out using different solvents (100% methanol, 100% ethanol, and 90% acetone). The chlorophyll contents including chlorophyll a,b,c,d and total chlorophyll were measured using spectrophotometry UV-VIS and expressed in µg/g of algae. The results showed that chlorophyll c could not be extracted using all used solvent, while chlorophyll b can only be extracted using acetone. Acetone produced the highest concentration of chlorophyll a (717.52 ± 9.71 µg/g), chlorophyll b (7.23 ± 0.24 µg/g), chlorophyll d (21.93 ± 1.07 µg/g), and chlorophyll total (746.67 ± 8.99 µg/g) compared to other solvent, that were significantly different (p<0.05). The second solvent to produce the highest concentration of chlorophyll a, d, and total chlorophyll was methanol which produced 578.77 ± 9.74 µg/g, 5.50 ± 0.12 µg/g and 584.27 ± 9.62 µg/g of chlorophyll content, respectively, followed by ethanol which produced 520.98 ± 2.52 µg/g of chlorophyll a, 3.56 ± 0.25 µg/g for chlorophyll d, and 524.54 ± 2.30 µg/g for total chlorophyll. Acetone is considered the most effective solvent to extract the chlorophyll content of Bulung sangu.

Authors: Arini L A 
Published: December 2021

Abstract
Reproductive organ cell damage due to oxidants can cause problems in female fertility, this situation can be prevented and overcome by consuming antioxidants such as algae. Green algae Chlorophyta also contains a steroid that is thought to be useful for normal reproductive health in women. The purpose of this study was to determine the compounds of sex steroid hormones in green algae which are important for female fertility. The systematic review method was used in this study. Based on the results of studies, it shows that green algae contain sterols which through biochemical mechanisms will form sex steroid hormones in the target organ. These hormones play an important role in the regulation of the female reproductive system and the balance of these hormones is crucial for normal fertility in women. Based on this, women should be able to maintain their reproductive health well by consuming foods that contain lots of vitamins and natural fibers that are good for the body such as green algae. Women must also be able to maintain a healthy lifestyle, change bad lifestyles, and avoid environmental risk factors that can cause infertility.
