Abstract

Tofu is a source of vegetable protein that has high nutritional value for Indonesian Tofu, which is made from soybeans, produces waste from production, one of which is tofu dregs which cannot be stored for long and can pollute the environment. In general, the protein content in tofu dregs is still high, while until now its use is still relatively simple, namely only as animal feed. The content of tofu dregs which is still high in nutrition needs to be optimized for its use as an alternative functional food by processing it into tofu dregs flour, where in 100% tofu dregs flour contains 66.24% carbohydrates, 17.72% protein, 3.23% crude fiber, and 2.62% fat. However, the lack of knowledge about tofu dregs management, knowledge about nutrition and the benefits of tofu dregs, as well as the lack of innovation that can be applied from tofu dregs, causes most of the tofu manufacturing entrepreneurs to still consider the economic value of tofu dregs to be low. The solutions that have been provided include (1) Counseling on the nutritional content that is still present in tofu dregs (2) Socialization on methods that can be applied to process tofu dregs into flour and the benefits of tofu dregs flour. The result of this service activity is that partners get additional knowledge about the management of tofu dregs into high-fiber and low-fat food flour.

Abstract

Daun kelor (Moringa oleifera) adalah bagian dari tumbuhan yang memiliki bentuk seperti daun dengan berbagai manfaat kesehatan dan gizi yang tinggi, serta terdapat kandungan vitamin, mineral, protein, dan senyawa bioaktif, serta memiliki sifat antioksidan dan antiinflamasi. Penelitian ini bertujuan untuk mempelajari ekstrasi, mengetahui keberadaan kandungan tannin pada daun kelor dan mengetahui model kinetika ekstraksi pada ekstrak yield daun kelor meggunakan metode Microwave Assisted Extraction (MAE). Proses ekstraksi daun kelor dilakukan dengan menggunakan pelarut etanol 96% dan menggunakan metode Microwave Assisted Extraction (MAE) dapat membantu memaksimalkan rendemen ekstraksi. Proses ekstraksi dilakukan dengan variasi daya 150 watt, rasio bahan terhadap pelarut 1:15 b/v dan waktu ekstraksi 2, 4, 6, 8, dan 10 menit. Hasil penelitian menunjukkan nilai rendemen tertinggi didapatkan pada waktu ekstraksi di menit ke 10 yaitu 10,25%. Model kinetika ekstraksi yang sesuai untuk mengekstraksi senyawa tanin dari daun kelor adalah orde 2, dimana nilai R2 lebih tinggi dibandingkan orde 1 dan nilainya hampir mendekati 1.

Abstract

Essential oil is compounds that contained in plants and have many benefits. Basil is an aromatic plant that can produce essential oils. Essential oils can be extracted from basil leaves using Microwave Assisted Hydrodistillation (MAHD) method. To determine the efficiency of the MAHD method, it’s necessary to study the kinetics of the extraction method. It’s because kinetic studies can be used to identify the optimal point in the process where the highest efficiency is obtained, so the extraction process can be optimized. The aim of this research is to evaluate the suitable kinetic model for the basil leaf extraction process using the MAHD method. This extraction using 100 grams of basil leaves and 200mL aquadest, heated at various microwave power 150W, 300W, and 450W. The extractions were carried out for 70 minutes with 10 min intervals. The results showed that the largest oil yield was obtained when using 450W power, which was 0.190 grams. Based on the experimental data obtained, the most suitable kinetic model is second-order model. This can be analyzed from the highest R2 (0.9946 – 0.9999) and the lowest RMSE (0.0062 – 0.0349). Increasing the irradiation power will affect the extraction rate and parameter values of each kinetic model.

Abstract

Ulva sp. is a green alga commonly found in Indonesian waters. It contains approximately 60% carbohydrates, 10–47% protein, and 1–3% lipids. This study aimed to determine the optimum conditions for lipid extraction from Ulva sp. A pre-treatment step was carried out by adding a Deep Eutectic Solvent (DES) and distilled water. The DES used was a mixture of zinc chloride and urea in a 1:2 molar ratio. The sample was then mixed with a chloroform-methanol solvent (2:1 v/v) and subjected to Microwave-Assisted Extraction (MAE). The variables investigated in this study included microwave power (150, 300, and 450 W), extraction time (10, 15, and 20 min), and solvent volume (45, 60, and 75 mL). The organic phase obtained from the extraction process was separated and evaporated to determine the lipid yield. The highest yield, 15.8%, was achieved under conditions of 20 min extraction time, 75 mL solvent volume, and 300 W of power. GC-MS analysis of the highest-yield sample revealed the presence of fatty acids including palmitic acid, oleic acid, and palmitoleic acid. This optimized method supports future applications in biodiesel production and green extraction processes for algae-based bioresources.

Abstract

AbstrakKrisis energi akibat kelangkaan minyak mentah telah menyebabkan kenaikan harga bahan bakar minyak dan gas secara signifikan. Untuk menanggulangi dampak tersebut, pemerintah memberikan subsidi LPG kepada masyarakat berpenghasilan rendah. Namun, realisasinya masih kurang efektif karena tidak tepat sasaran, sehingga menyebabkan keterbatasan ketersediaan LPG bersubsidi. Di sisi lain, limbah biomassa seperti jerami padi dan kotoran sapi yang melimpah di wilayah pedesaan belum dimanfaatkan secara optimal, padahal memiliki potensi besar sebagai sumber energi terbarukan.Kegiatan pengabdian ini dilakukan di Desa Sumber Jeruk, Kabupaten Jember, dengan tujuan memberikan solusi pemanfaatan limbah biomassa menjadi energi alternatif berupa biogas, sekaligus sebagai upaya mengurangi ketergantungan terhadap LPG. Metode yang digunakan dalam produksi biogas adalah fermentasi fed-batch dengan penambahan EM4 sebagai aktivator mikroorganisme.Hasil kegiatan menunjukkan bahwa kombinasi jerami padi dan kotoran sapi mampu menghasilkan biogas yang dapat dimanfaatkan sebagai bahan bakar alternatif. Selain membantu mengurangi limbah organik, inovasi ini juga berkontribusi dalam mendukung ketahanan energi di tingkat rumah tangga. Pengolahan limbah biomassa menjadi biogas merupakan solusi tepat guna yang ramah lingkungan dan berkelanjutan dalam menghadapi keterbatasan energi fosil. Kata kunci: biogas; LPG; limbah jerami padi; kotoran sapi; fermentasi fed-batch. AbstractThe energy crisis due to the scarcity of crude oil has caused a significant increase in the price of fuel oil and gas. To overcome this impact, the government provides LPG subsidies to people with low incomes. However, its realization is still ineffective because it is not on target, resulting in limited availability of subsidized LPG. On the other hand, biomass waste such as rice straw and cow dung which are abundant in rural areas have not been optimally utilized, even though they have great potential as renewable energy sources. This community service activity was carried out in Sumber Jeruk Village, Jember Regency, with the aim of providing a solution for utilizing biomass waste into alternative energy in the form of biogas, as well as an effort to reduce dependence on LPG. The method used in biogas production is fed-batch fermentation with the addition of EM4 as a microorganism activator. The results of the activity show that the combination of rice straw and cow dung is able to produce biogas that can be used as an alternative fuel. In addition to helping reduce organic waste, this innovation also contributes to supporting energy security at the household level. Processing biomass waste into biogas is an appropriate solution that is environmentally friendly and sustainable in overcoming the shortage of fossil fuel energy. Keywords: biogas; LPG; rice straw waste; cow manure; fed-batch fermentation
