Water naturally contains various minerals, one of them is fluoride ion. Fluoride in water with suitable amounts give good benefits for health, but give the opposite result in excessive amounts. The purpose of this study was to determine the levels of fluoride contained in bottled drinking water and some well water samples in Banda Aceh. The fluoride amount in bottled drinking water and the well water was analyzed using UV-Vis Spectrophotometry at 570 nm wavelength. The measurement results show that the six samples have fluoride ion levels below 1 mg/L. This proves that the water is suitable for consumption and use because it meets the quality standards of SNI 01-3533-2006 (maximum 1 mg/L for bottled drinking water) and the Health Minister Regulation of Republic Indonesia Number 32 Year 2017 (maximum 1,5mg/L in water for hygiene and sanitation purposes).

Telah dilakukan penelitian dengan tujuan untuk mengetahui pengaruh penambahan tawas Al2(SO4)3 dan soda ash Na2CO3 terhadap turbiditas dan pH air baku pada instalasi pengolahan air bersih (IPA). Dari penelitian ini diperoleh bahwasanya tawas Al2(SO4)3 dan soda ash Na2CO3 dapat membantu proses koagulasi-flokulasi sebagai penyangga pH. Pengaruh penambahan tawas dan soda ash pada air baku yaitu dapat menurunkan kadar turbiditas dan mempertahankan pH pada air baku (yang telah diolah). Sehingga menghasilakan air bersih yang sesuai standar baku mutu menurut Permenkes No. 32 Tahun 2017.

Essential oil is a type of oil that is produced from various parts of the plant, is a thick liquid at room temperature, and evaporates easily, giving it a distinctive aroma. One of the essential oils is used as an antibacterial compound. This study aims to measure the variation in the deposition of various types of essential oils as an inhibitor of the growth of Staphylococcus aureus bacteria. This research method is a Literature Review by examining the use of various concentrations of various types of essential oils to inhibit the growth of Staphylococcus aureus bacteria. The best inhibition of growth of Staphylococcus aureus bacteria was obtained in the essential oil of basil leaves at a concentration of 4% with inhibition of 40.35 mm. Meanwhile, the lowest inhibition of growth of the Staphylococcus aureus bacteria for black fungus isolates was obtained at a concentration of 0.5% with an average inhibition zone of 1.16 mm.

The technology transfer program for processing Thok fish sausages has been implemented for the fisherwomen in Gampong Neuheun. Based on interviews, the main issues faced are the lack of skills in using materials, tools, and technology for processing Thok fish products. Additionally, the absence of a coordinating business entity for fish processing reduces community motivation. The aim of this activity is to provide Thok fish sausage processing technology to the fisherwomen in Gampong Neuheun. The implementation methods include surveys, socialization, and training, with evaluations through pre-tests and post-tests. Results show a 90% increase in skills and knowledge, as well as an 85% increase in motivation. This training facilitates the management of fish catches during the harvest season.

Castor seed oil (Ricinus communis L) can be utilized for the manufacturing of membranes reacted with toluene diisocyanate (TDI). The aim of this study was to examine the effect and membrane characteristics of castor seed oil with a combination of silica used as an adsorbent, with a combination of silica (SiO2) 0.5 mg, 1 mg, 1.5 mg, and 2 mg. The initial analysis of the membrane was carried out with a swelling test of 1.5 mg of silica variation to obtain the most ideal result of 200%. The best chemical resistance characterization occurred at a variation of 1.5 mg of silica. Further characterization, particularly the FTIR test, thermal test, mechanical test, and SEM test, showed that there were Si-O groups and amine groups (NH2), and on the membrane there were groups OH, C=O, and NH. The thermal characterization of the silica membrane (1.5 mg) gave the greatest residue concentration, measuring 3.2%. In mechanical terms, the silica membrane has a higher elongation value than the membrane. In SEM characterization, the silica membrane has holes and is solid. This study indicated that the highest drop in Fe metal occurred at an immersion period of 6 hours with a combination of silica with a flux value of 9.25 L/m2 hour and a rejection value of 0.098%.

This study utilised molecular docking to predict the binding affinity of various fatty acids (FAs) found in Swietenia humilis to the sortase A (SrtA) protein target from Staphylococcus aureus. Binding energies, measured in kcal/mol, indicated the strength and stability of ligand-protein interactions, with lower values signifying stronger binding. The binding affinities of eight FAs as the active constituents in n-hexane extract of S. humilis and the positive control, gentamicin, were compared to assess their theoretical antibacterial activity. Palmitoleic acid exhibited the strongest binding affinity (-5.6 kcal/mol) among the FAs, suggesting the highest potential antibacterial activity, followed by linoleic, palmitic, linolenic, arachidic, tricosanoic, stearic, and oleic acids in decreasing order of affinity. Despite having weaker binding energies than gentamicin, a common gram-positive inhibitor from aminoglycoside derivative, FAs showed multiple hydrogen bonds and van der Waals interactions with key residues like ARG197, VAL168, VAL166, and ILE182, contributing to their binding stability. Palmitoleic acid formed multiple hydrogen bonds (ARG197 and GLY119) and significant van der Waals interactions, highlighting its strong theoretical binding. Stearic and oleic acids, although having higher binding energies, also formed critical hydrogen bonds, suggesting moderate potential activity. Gentamicin's single hydrogen bond suggests a highly specific binding site, which may result in high antibacterial activity despite fewer interaction points. The study indicated that FAs like palmitoleic and oleic acid show substantial potential as supplementary antibacterial agents, especially in the context of combating antibiotic resistance. This finding can pave a path for drug design and development to address the S. aureus's resistance.

This study investigates the potential of natural stimulants, specifically ecdysteroids, in accelerating the molting process in mangrove crabs. The research was conducted by analyzing various plants containing ecdysterone and their effects on the crabs. The results indicate that forest fern leaves and mulberry leaves are effective sources of ecdysterone in stimulating molting and growth in crabs. The use of such natural stimulants has the potential to enhance productivity and reduce reliance on synthetic hormones in crab cultivation. However, further research is needed to determine the optimal dosage and to understand the mechanisms of ecdysterone action in crabs in more detail. The main challenge in implementation is adjusting the dosage and frequency of natural stimulant administration to achieve optimal results without disrupting the balance of the cultivation ecosystem. This approach offers an environmentally friendly alternative for the sustainable development of crab farming.
