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
