According to the Regulation of the Minister of Health No. 32 of 2017, the permissible content of Manganese in dug well water is 0.5 mg/L. The purpose of this study was to determine the concentration of Mn (II) ions in water before and after passing through a Moringa Seeds Powder (MSP)-TiO2 membrane 20:1; 20:3; 20:5; 20:7; 20:9 and measure the percentage decrease in the concentration of Mn (II) ions in water after through the MSP-TiO2 membrane. The object of this research is a 55 ppm Mn (II) ion artificial sample at a flow rate of 0.56 mL/minute for 90 minutes with 90-watt radiation UV. The concentration of Mn (II) ion was measured by visible spectrophotometric method, the morphology of MSP, TiO2, and MSP-TiO2 membranes was characterized by SEM-EDX, and its diffraction spectra by X-Ray diffraction. The results obtained that the initial Mn(II) was 55.06 ± 0.031 ppm, the concentration of Mn (II) ions with the MSP-TiO2 membrane of mass MSP-TiO2 were 20:1; 20:3; 20:5; 20:7; 20:9 respectively 36.47±0.00; 44.16±1.15; 44.31±1.04; 44.94±0.94; 42.27±2.61 ppm. The percentage of decrease concentration of Mn (II) ion are 34.19±0.44%; 21.37±0.43%; 20.94±0.85%; 19.24±0.86%; and 19.66±0.86%. The highest percentage decrease in Mn (II) ion concentration was 34.15±0.44% in the variation of mass MSP-TiO2 20:1.

The use of cellulose acetate is very diverse, such as in the film industry, biodegradable plastics, paper coatings, metals, and glass, as an adhesive for topographic films as the main raw material in membrane synthesis processes. Therefore, it is necessary to characterize cellulose and cellulose acetate from nutmeg shell waste (Myristica fragrance) in South Aceh. The method used is in the form of cellulose isolation using the soxhletation process, then bleaching and hydrolysis processes are carried out, then it is synthesized into cellulose acetate. Characterization of cellulose by determining % yield, cellulose content, ash content, moisture content, FTIR, XRD. Characterization of cellulose acetate by determining the acetyl content and FTIR.

Some bacteria that can cause infection are Escherichia coli, Salmonella typhi, Staphylococcus aureus, and Bacillus subtilis. Infection can be prevented by antibiotic therapy. Excessive use of antibiotics such as misuse of indications, free use in the community, inappropriate doses, and timing of application will cause new problems such as increasing bacterial resistance to antibiotics. The prevalence of drug-resistant bacteria is increasing in many parts of the world. However, this increase is accompanied by a downward trend in the development of new antibiotics. Thus, to overcome this problem new antibiotics have to be developed. This study aimed to synthesize a new antibiotic, namely to test amoxicillin/CuO and its antibacterial activity against E. coli, S. typhi, S. aureus, and B. subtilis. Antibacterial activity test using disc diffusion method. The XRD characterization results showed that the diffraction peaks of amoxicillin/CuO in the image above started from 21.13; 29.54; 30.67; 36.82; 39.5; 42.05; and 47.88. The SEM results of the Amoxicillin/CuO compound showed that the particle size of the compound was still in the form of a graph of 196-345 nm. The results of testing the antibacterial activity of amoxicillin/CuO compounds against E. coli, S. typhi, B. subtilis, and S. aureus showed that amoxicillin/CuO compounds had activity against all bacterial samples.

It was confirmed that there were the changing of molecular interaction between PEC chitosan-alginate films due to presence of kelor extract, indicating that PEC chitosan-alginate films with kelor extract had been formed.

Rich mineral sea salt is a consumption salt with a NaCl content of <50% used to live a low sodium diet for a healthy lifestyle. In general, traditional sea salt was produced with the multistage evaporation method to obtain a NaCl content of ≥ 94.7%, whereas the production of rich mineral sea salt uses a total evaporation method and then removes the salt flower at a certain concentration to get low sodium chlorine and contain other natural minerals. This study aims to analyze the chemical content of the raw material of rich mineral sea salt. The location of seawater used as raw material for rich mineral sea salt is Camplong District, Sampang Regency. Samples were obtained from sea level with a distance of ± 400 m from the coastline and carried out during high tide conditions. The chemical analysis of seawater samples consists of Na, Mg, Ca, K, Fe, Cl− dan SO42−. The analysis method is based on the Indonesian National Standard of environmental quality test. The results of the major mineral analysis showed that the largest mineral content of seawater was calcium (Ca2+) at 492.350±10.395 mg/L and Sodium (Na+) at 482,000±1.979 mg/L.
