Abstract

Many studies have been conducted and developed on cellulose-based battery separator materials, including bacterial cellulose, which has characteristics like plant cellulose. This research aims to synthesize BC/Al2O3 composite and analyze its potential as a battery separator. The synthesis of the composite with the ex-situ method is to immerse BC from tofu liquid waste (fermentation time variation of 6, 7, and 8 days) into Al2O3 suspension. The characterization results showed that the immersion of Al2O3 in BC can increase porosity, electrolyte absorption, and conductivity, indicating that the composite has the potential to be used as a battery separator.

Abstract

Sponges are marine biota that makes up coral reefs that live on the bottom of the waters and have an important role in marine ecosystems. Sponges have bioactive components that have not been widely used by the community. This study aimed to analyze the content of secondary metabolites and the antibacterial activity of the sponge Stylotella sp. antibacterial activity test against Gram-negative (-) Escherichia coli and Gram-positive (+) Staphylococcus aureus was carried out using the good diffusion method. The results of antibacterial testing with various concentrations of 50, 100, and 150 ppm of the isolates showed that the zone of inhibition against E. coli was 11.3; 12; and 13 mm while for S. aureus was 12.3; 13; and 14 mm. The results of antibacterial testing with a concentration of 600 ppm of sponge extract showed an inhibition zone on E. coli and S. aureus in the amount of 13.3 and 14 mm, respectively. The test results showed that the sponge extract and isolate were in the intermediate category and were resistant to E. Coli bacteria. and S. Aureus

Abstract

Stunting is a chronic nutritional problem resulting from a state of malnutrition that lasts long enough. One area in Indonesia that still faces stunting problems is Tirtanadi village, Labuan haji sub-district, East Lombok district, West Nusa Tenggara province. Factors that cause stunting are low understanding of stunting and poor sanitation. Both of these things lead to a lack of nutritional intake for infants, children, and pregnant women. One of the efforts to prevent stunting can be done by utilizing agricultural products to be processed high in nutrition. Tirtanadi Village is a producer of corn as the main agricultural product and has not been used optimally. Corn is processed into various types of food such as pudding and corn nuggets with a high taste. The utilization of corn in processed food with a preferred taste can be done to increase the family's nutritional intake while at the same time increasing the family's economy.

Abstract

Desa Jurit Baru merupakan salah satu desa di kabupaten Lombok Timur yang memiliki hasil perkebunan berupa nira aren. Selama ini nira aren yang didapatkan belum dimanfaatkan secara optimal. Salah satu olahan nira aren yang dapat dijadikan bahan makanan adalah produk nata. Oleh sebab itu dilakukan suatu kegiatan sosialisasi melalui program pengabdian kepada masyarakat yang bertujuan meningkatan pengetahuan, sikap, dan keterampilan masyarakat Jurit Baru tentang pemanfaatan nira aren sebagai bahan baku pembuatan nata serta merangsang minat kewirausahaan peserta. Target khusus program ini berupa produk nata yang menggunakan nira aren sebagai bahan dasarnya. Kegiatan ini terdiri dari 3 tahapan yaitu: (1) penyuluhan mengenai pemahaman secara teoritis mengenai pengertian teknologi fermentasi pada pembuatannya; (2) praktik pembuatan nata dari nira aren; serta (3) pendampingan kegiatan produksi dan pengemasan. Kegiatan pelatihan dan pembinaan perlu dilakukan secara berkesinambungan untuk mencapai tujuan utama dari kegiatan ini yaitu meningkatkan perekonomian masyarakat.

Abstract

Covid-19 has caused more than 14 million confirmed cases and more than 6 hundred deaths as of 21 July 2020 globally. However, there is no approved drug to treat the disease. Xanthone is a potential therapeutic option for the virus that have been tested using molecular docking. There were 12 of xanthone compounds and its derivatives which have been docked against two protein crystals, 2GX4.pdb and 6FV1.pdb, which obtained two potential compounds of hydroxyxanthone derivatives with sulfonate and chloro substitution. These compounds are potentially developed into one of the agents for the treatment of infection COVID-19 disease. Based on energy data and interactions with amino acid residues when compared with its own native ligands, namely NOL and E8E, respectively. Energy docking and energy docking interactions are equal to - 43.3057and - 45.5805 Kcal/mol respectively, during interactions with amino acid residues in the form of Gly 142, His 163, Cys144, Glu166, Gln164 and His 41. Based on these two data, it can be concluded that trihydroxyxanthone compounds 4 and 8 with chloro and sulfonate substitution are very potential to be developed as drug agents for Covid-19 disease therapy through protease inhibition.
