Published: July 2021

Abstract
Non-invasive cancer treatment has the potential to eliminate infection and scar formation associated with surgery to minimize side effects. Light stimulation can use for treatment to increase efficiency, reduce treatment costs, eliminate infection, etc. Magnetic fields can improve blood circulation in tissues and stimulate the body’s metabolism. The magnetic field can induce joule heating and expand the blood vessels of cancerous tumors. These blood vessels increase the possibility of excess oxygen to enter the tumor creating obstacles to the survival of oxygen-rich cancers. In this study, we investigate finite difference times domain (FTDT) simulation of magnetic field in normal and blood cancer. The low frequency with range 10-106 is used in this study. The maximum magnetic field for normal blood and CLL1 is 400 nm and 250 nm in 125 cm electrode size. While for 50 nm electrode size, the maximum magnetic field in normal blood and CLL 1 is 400 nm and 300 nm. But there The maximum magnetic field for normal blood and CLL1 is 400 nm and 250 nm in 125 cm electrode size. While for 50 nm electrode size, the maximum magnetic field in normal blood and CLL 1 is 400 nm and 300 nm. But there is no peak for blood cancer in final stage CLL2.

Quantum teleportation of two-qubit states via W-State and GHZ-like States
Authors: Nusur F 
Published: July 2021

Abstract
We investigate the criteria for two-qubit states that could be transmitted via W-state. The appropriate criterias are entangled states which have maximum number of terms equal to number of channel terms and maximum of two different constants. We have also shown quantum teleportation of a particular type of two-qubit state via three-qubit GHZ-like states, with Alice possesses the first qubit of the channel and the rest belongs to Bob. GHZ-like state is an entangled state which has different characteristic from GHZ state. It is stronger against particle loss than GHZ state. Furthermore, GHZ-like states which can teleport a particular type of two-qubit state are GHZ-like states which have two terms.

Published: July 2021

Abstract
We characterize single- and few-electron backgrounds that are observed in dual-phase liquid xenon time projection chambers at timescales greatly exceeding a maximum drift time after an interaction. These instrumental backgrounds limit a detector's sensitivity to dark matter and cosmogenic neutrinos. Using the ∼ 150 g liquid xenon detector at Purdue University, we investigate how these backgrounds, produced after 122 keV 57Co Compton interactions, behave under different detector conditions. We find that the rates of single- and few-electron signals follow power-laws with time after the interaction. We observe linearly increasing rates with increased extraction field. The relationship of the rates in the single-electron background with increased drift field is unclear. Normalizing the rates to the primary interaction's measured ionization signal, the rates increase linearly with the depth of the interaction. We test the hypothesis that infrared photons (1550 nm) would stimulate and accelerate electron emission via photodetachment from impurities, but find that even 1 Watt of infrared light fails to reduce these backgrounds. We thus provide a characterization that can inform background models for low-energy rare event searches.

Abstract
It is well known that greenhouse gas effects are one of the main factors driving global warming. Substances that play a role in this phenomenon include Carbon dioxide (CO2), Methane (CH4) and Nitrous oxide (N2O) which is commonly called as Carbon Substances. The higher the levels of these substances in the air, the greater and faster impact of the greenhouse phenomenon can cause. The current status of global warming has encouraged us to make efforts to reduce and mitigate climate change. Calculation of the addition of carbon substances (Carbon Footprint Inventory - CFI) is the first step in an effort to deal with climate change. It is therefore, as one form of participation in the mitigation of global warming, the calculation of carbon production (carbon footprint) in Tunas (Tuna, Mackerel Tuna and Skipjack) fisheries has been done. The research was subject to Tunas production captured using Pole and Line and landed at Bitung fisheries port. This research utilized primary data collected by field survey, questionnaire, expert adjustment, and secondary data from various data sources both online and offline. The number of respondents were 16 fleets of Pole and Line based in Bitung fisheries port, including its captains, engine master and fishing master in each fleet. Several companies such as ice factories, processing and fuel dealers were also subjected as respondents. Flow charts and Life Cycle Analysis (LCA) are used to map the needs and availability of data which are then applied to CFI based on ISO / TS 14067. CFI ISO/TS 14067 internationally has been published specifically to calculate the CFI of products. The result shows CFI of Tunas product in Bitung was 1.41 ± 0.80 kgCO2/kg of Tuna. This number is considered low compared to the CFI tuna fisheries on an international scale reported by the environmental working group - Americans for Prosperity (AFP) which is about 6.1 kg CO2/kg of fish. Unfortunately the report from AFP was stated in the general without recognizing the fishing gear whereas in this research it had only calculated the CFI on Pole and Line fisheries.

Abstract
A study on the water quality in a body of water is an important thing to do, especially for the waters that are vulnerable to contamination and classified as the productive waters area. Nolloth Village has conservation waters that are managed by the local community based on local wisdom, i.e. Labuang Sasi with an area of 23.85 hectares. It is used by the people of Nolloth Village for fishing. However, managing coastal resources is also inseparable from the low understanding of the local community concerning the true value of coastal resources as a whole. The extraction of natural resources by coastal communities still leaves waste. Therefore, this study aimed to determine the condition of the water quality in Labuan Sasi Waters, Nolloth Village, Central Maluku. The employed parameters in this study included pH, DO, salinity, and temperature at 4 observation stations. The applied method in this study was the direct measurement on the surface of Labuan Sasi Waters in Nolloth Village. The obtained results of measurements indicated that in-situ DO in Labuang Sasi Waters ranged from 4.87 to 4.89 mg/l; in-situ pH ranged from 7.21 to 7.67; the in-situ temperature ranged from 29.30 to 30.500C; and in-situ salinity ranged from 4.87 to 4.89‰. Overall, the results of measurement and the analysis of water quality parameters in Labuang Sasi Waters indicated that the waters are in good condition and can support the life of the marine biota.

Abstract
Maluku is one of the provinces which has extensive fishery potential. However, the utilization of fishery potency in the District of Seram Bagian Barat’s maritime territory as one of the fishery management areas in Maluku, only reaches 40%. It shows that there is a huge opportunity for the development of capture fisheries business in the District of Seram Bagian Barat. The output determinants of the purse seine capture fisheries business are running cost, shore cost, and labor cost. The number of samples in this research is 60. Using the purposive sampling method, the samples are collected from the data of 20 business units for 3 consecutive years (2016-2018). This research is a Descriptive research with quantitative approach, which profitability is measured by ROI (Return On Investments) and the data analysis technique applied is the multiple linear regression with the smart PLS 3.0 program. The research is resulted in several conclusions. First, running cost variable has a positive and significant influence towards profitability (ROI), which proves that the District of Seram Bagian Barat’s maritime territory is still in the state of under exploited for small pelagic fish. Second, shore cost variable has a negative and significant influence towards profitability (ROI) which describes that the distance between fishing based to the target market is considerable obstacle. Third, the labor cost variable has a positive influence towards profitability (ROI), which shows that the amount of catch is not only determined by the number of crews and the size of the net but also by the skills and abilities of each crew to perform their respective duty correctly.

Authors: Novarianto H , Tulalo M A , Mawardi S 
Published: July 2021

Abstract
One alternative coconut product of high economic value is coconut sugar. Coconut sugar is processed from tapped sap collected from bunches. Nationally, coconut sugar production reaches around 300,000 tonnes / year. The demand for coconut sugar in Indonesia, especially as a raw material for sweet soy sauce production, increasing by 10% every year. Due to sluggish demand, raw materials for the coconut sugar soy product has been decreasing in recent years. The shortage of coconut climbers collecting coconut sap is the cause of this issue, which is caused by a number of factors, including the fact that young tappers are less interested in climbing tall coconut palms. To solve this problem, it is important to determine the potency of dwarf coconuts, which have a shorter trunk and bear fruit earlier. This study was aimed to evaluate and conduct selection of Dwarf coconut varieties that have high yield potential as a producer of sap and coconut sugar. The research was conducted in North Sulawesi Provinces by evaluating nine Dwarf coconut varieties. The results of research on the production of coconut sap and sugar from nine Dwarf coconut varieties with different plant ages, obtained mixed results among coconut varieties. The time length of tapping sap varies between 31.42 and 43.21 days/bunch, the amount of sap varies between 1.1 and 3.3 liters/tree/day, the sap pH ranges from 6.49 to 7.86, Brix ranges from 14.01 to 17.64, sugar yield ranges from 14.54 to 18.95%, and sugar production ranges from 0.16 to 0.42 kg/tree/day. Waingapu Red Dwarf (WRD), Salak Green Dwarf (SGD), and Nias Yellow Dwarf (NYD) are the Dwarf coconut varities with the highest potential sap and sugar yields, with potential sugar yields of 2.09 tons, 1.64 tons, and 1.56 tons/month/ha, respectively. These Dwarf coconut are hoped to be grown in several provinces that produce coconut sugar to assist coconut farmer.

Abstract
This Study aims to determine the effect of the application of liquid organic fertilizer (LOF) combined with various levels of basic fertilizer in an effort to improve growth and increase soybean production. The research used 2 factorial randomized block design (RBD). The first Factor K (LOF) concentration consisted of ; K1 = 10.7%; K2 = 14.3% and K3 = 17.9%. The second factor is D (ratio of inorganic fertilizer N, P2O5, K2O), D1 = 30: 80: 30, D2 = 40: 90: 40, D3 = 50: 100: 50. The treatment was repeated 3 times. Data was analyzed using analysis of variance. The results showed that there was no significant difference between the treatments for the observed parameters. The combination of K2D3 treatment resulted in soybean production reaching 3.2 tons / ha which was not significantly different from other treatment combinations. TThis research showed that Anjasmoro variety was able to produce 2.09 - 3.20 ton / ha, there are up to 42.2% higher than the description of the this variety, which only had a yield of 2.03-2.25 ton / ha. The results showed that the use of LOF in soybean plants could reduce the use of chemical fertilizers, thereby reducing production cost and increasing farmers’ income. In the future, processing organic waste into LOF can be used to increase land productivity, prevent land degradation, and be a solution in overcoming the problem of organic waste.

Abstract
The hand is one of the pathways for spreading disease through bacterial contamination, so an antibacterial agent must be applied as a handwashing agent. A practical alternative to washing hands is to use an antiseptic gel. Nutmeg contains active compounds as antibacterial agents. This research aimed to obtain the most suitable formulation of nutmeg oil antiseptic gel as a hand sanitizer. Nutmeg oil antiseptic gel preparations were made in three different formulations with concentrations of 15% (F1), 20% (F2), and 25% (F3). The physical properties stability test of gel included freeze-thaw for stability test, pH, homogeneity, organoleptic, spreadability, and adhesion test. The results showed that the gel was white and had a peculiar smell of nutmeg, the gel form was semisolid, and the pH value was 6. Based on the freeze-thaw test, the preparation is stable in 3 cycles. The results of the spreadability and adhesion tests were influenced by differences in nutmeg oil concentration. That the nutmeg oil concentration of 25% (F3) was found to be the optimal formulation because it meets all the requirements for the physical properties of the gel.
