Abstract

Indonesia is a tropical country located on the equator with high sun exposure, so sunscreen is needed to reduce the risk of exposure to ultraviolet (UV) light. In this research, a sunscreen was developed that uses natural active ingredients in the form of lignin made from coconut coir. The aim of this research is to determine the comparison between the mass of coconut coir and the volume of ethanol solution that produces the highest lignin content, as well as the concentration comparison between lignin nanoparticles and commercial sunscreen that produces the highest SPF value. The synthesis of lignin from coconut coir was carried out using an extraction method using ethanol solvent, followed by a hydrolysis process with NaOH and acidification with H2SO4, while lignin nanoparticles were made using a pH shifting method using ammonia and HCl. The lignin nanoparticles formed are then added to the sunscreen's active ingredient. The variables used were the ratio of the mass of coconut coir to the volume of 80% ethanol solvent (1:5, 1:10, 1:15, and 1:20 (w-v)) and the concentration of lignin in commercial sunscreen cream (2%, 4%, 6%, 8%, and 10% (w-w)). The results of the research show that the higher the solvent ratio, the more lignin is produced, but will decrease after reaching the optimum point. The optimal solvent volume occurs at a ratio of 1:15 (w-v) with a yield of 12.94% (w-w). In addition, the higher the lignin concentration, the resulting SPF value will also increase. The best concentration is 10% (w-w) at a solvent ratio of 1:15 (w-v) with an SPF value of 22.23.

Abstract

Rice bran has the potential to become a nutritional component that reduces disease risk and improves physical health. In addition, rice bran is a hypoallergenic (allergen-free) component which is a good source of dietary fiber. Rice bran oil extraction (RBO) is one of the most popular uses of rice bran. Judging from the health benefits and healthier composition, rice bran oil is very appropriate. The most unsaturated fatty acids are found in rice bran oil which has a composition of 80% unsaturated fatty acids. In taking yields, the extraction method is a practical and effective technique. This research aims to understand the effect of temperature, mesh size, and extraction time on the yield value and FFA RBO content. This Soxhlet uses several variables, with temperature variables of 60°C, 65°C, 70°C, 75°C, 80°C while time variables of 1, 2, 3, 4, and 5 hours with variations in mesh size of 100 and 60. The research results show that soxhletation extraction at mesh 100 optimum increases at a temperature of 70°C within 4 hours. Where the yield of oil produced was 11.62%. Meanwhile, for mesh 60, the optimum increase occurred at a temperature of 65°C within 4 hours with an oil yield of 12.90%. Rice bran oil extraction, the content of in rice bran oil extraction, the content of alkenes, aldehydes, and alkene bending.

Abstract

Fly ash, as waste from burning coal, contains dominant amounts of silica (SiO2), so it can be used as a source of silica. Silica synthesis can be done by reacting fly ash with an alkaline solution and precipitating the silica with an acidic solution. In this research, the variables used are the type of reactant, process temperature and the mass ratio of the raw material to the reactant, with the aim of knowing the silica yield produced. Silica synthesis was carried out using 3M NaOH and KOH with variations in temperature (75, 85, 95, 105 oC), mole ratio of fly ash to NaOH (1:10.09; 1:12.61; 1:15.13) and KOH ( 1:7.34; 1:9.17). The initial fly ash content was carried out by XRF analysis and the silica resulting from the extraction process was calculated by % yield and SEM analysis. The research shows that the highest % yield at a temperature of 950C and mole ratio of 1:15.13 is 105.6% using NaOH solvent and a raw material: reactant ratio of 1:11 of 1.184 grams with yield of 43.05% using KOH solvent, Yields that exceed 100% are caused by impurities that are taken in during the silica extraction process. The silica results in both reactant type variables have an average particle size of 36 -77 nm.

Abstract

Azadirachta indica, Acalypha indica, and Muntingia calabura are wild plants with antioxidant content capable of treating various diseases. This study aims to evaluate phytochemical compound screening using qualitative tests and to characterize them using FT-IR (Fourier Transform Infrared Spectroscopy) in Azadirachta indica, Acalypha indica, and Muntingia Calabura, as well as to assess total phenolic content (TPC), flavonoid content (TFC), and antioxidant potential. The results showed that Azadirachta indica and Acalypha indica contained alkaloids, flavonoids, tannins, saponins, phenols, glycosides, steroids, and carbohydrates but lacked proteins and triterpenoids. In contrast, Muntingia Calabura leaf extract lacked glycosides, triterpenoids, and carbohydrates. The highest TPC content in Muntingia Calabura extract was 269.88±0.00 mg GAE/gr extract, and the highest TFC was found in Azadirachta indica extract at 676.34±21.85 mg CE/gr extract. The ethanol extract of Azadirachta indica and Muntingia Calabura leaves has very strong antioxidant activity, with IC₅₀ values of 32.76 ± 3.02 ppm and 31.16 ± 1.96 ppm, respectively, while Acalypha indica had an IC₅₀ value of 107.71 ± 3.55 ppm, indicating a moderate level of antioxidant activity. These results support the potential of the three medicinal plants as sources of natural antioxidants. The findings can stimulate further research to isolate key bioactive compounds and perform toxicity tests to support potential applications in the pharmaceutical and food industries.

Abstract

Penurunan kualitas air sungai ditandai oleh meningkatnya kesadahan total dan kekeruhan yang dapat mengganggu pemanfaatannya sebagai sumber air baku. Penelitian ini bertujuan untuk membandingkan efektivitas karbon aktif dan batu apung sebagai adsorben dalam menurunkan kesadahan total dan kekeruhan air sungai menggunakan sistem adsorpsi kolom kontinu. Air sungai dengan nilai awal kesadahan total sebesar 373 mg/L CaCO3 dan kekeruhan 30,4 NTU dialirkan melalui kolom adsorpsi dengan variasi massa adsorben sebesar 200, 250, 300, 350, 400, dan 450 gram. Hasil penelitian menunjukkan bahwa peningkatan massa adsorben cenderung meningkatkan efisiensi penurunan kedua parameter kualitas air. Karbon aktif menunjukkan kinerja paling optimal, dengan efisiensi penurunan kekeruhan mencapai 87% dan kesadahan total sebesar 77% pada massa adsorben 450 gram. Sementara itu, batu apung menghasilkan efisiensi penurunan kekeruhan sebesar 83% dan kesadahan total sebesar 67% pada kondisi yang sama. Perbedaan kinerja kedua adsorben dipengaruhi oleh karakteristik fisik dan kimia material, khususnya luas permukaan dan struktur pori, yang berperan penting dalam mekanisme adsorpsi. Berdasarkan hasil tersebut, karbon aktif dinilai lebih efektif dibandingkan batu apung dalam sistem adsorpsi kolom kontinu, meskipun batu apung tetap memiliki potensi sebagai adsorben alternatif yang lebih ekonomis untuk pengolahan air sungai skala kecil hingga menengah.

Abstract

This study aims to determine whether there is an influence between financial literacy, financial behavior, and income on investment decisions of rural communities during the Covid-19 pandemic. This type of research is quantitative research with data obtained from distributing questionnaires to 110 village residents. The data analysis used included descriptive analysis and multiple linear regression analysis with the help of the SPSS version 25 program. This study concludes that financial literacy has a positive and significant effect on investment decisions. Unlike the case with financial behavior which has a negative and significant influence on investment decisions. Similar to financial literacy, income also has a positive and significant influence on investment decisions. People should improve their investment decisions because they can be used for savings in preparing for future needs. This can be done by setting aside a portion of the income received, studying and understanding various kinds of financial information and how to manage finances.
