<![CDATA[The increasing volume of household waste has occurred in parallel with population growth and rising household activities. Limited public knowledge regarding household waste management has resulted in waste being disposed of without further processing, leading to environmental pollution. At the same time, the intensive use of chemical fertilizers has contributed to declining soil fertility and increased production costs for smallholder farmers due to rising prices of non-subsidized fertilizers. This community service program aimed to empower the Sumber Tani Farmer Group in Arjasa Village, Jember Regency, through training on the production of eco-enzymes from household organic waste as a strategy to improve soil fertility and enhance farm cost efficiency. The program was implemented using a participatory approach (learning by doing), consisting of three main stages: preparation and coordination, implementation (counseling, demonstrations, and hands-on practice), and evaluation. Conducted from August to October 2025, the activity involved 30 members of the farmer group. The results demonstrated an increase in participants’ knowledge and skills in processing organic waste into eco-enzymes and applying them to agricultural land. Overall, the program successfully promoted farmer self-reliance in the provision of liquid organic fertilizers, reduced dependence on chemical inputs, and supported the development of environmentally friendly and sustainable agricultural systems.ABSTRAKPeningkatan volume limbah rumah tangga terjadi seiring peningkatan populasi dan aktivitas rumah tangga. Minimnya pengetahuan masyarakat tentang pengelolaan limbah rumah tangga sehingga limbah terbuang tanpa diolah lebih lanjut yang berdampak pada pencemaran lingkungan. Di sisi lain, penggunaan pupuk kimia secara intensif telah menyebabkan penurunan tingkat kesuburan tanah, serta meningkatkan biaya produksi bagi petani skala kecil akibat kenaikan harga pupuk nonsubsidi. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberdayakan Kelompok Tani Sumber Tani di Desa Arjasa, Kabupaten Jember, melalui pelatihan pembuatan eco-enzyme dari limbah organik rumah tangga sebagai solusi perbaikan kesuburan tanah dan efisiensi biaya usaha tani. Metode pelaksanaan kegiatan dilakukan melalui pendekatan partisipatif (learning by doing) yang meliputi tiga tahapan utama: persiapan dan koordinasi, pelaksanaan (penyuluhan, demonstrasi, dan praktik langsung), dan evaluasi. Kegiatan yang dilaksanakan pada bulan Agustus–Oktober 2025 ini diikuti oleh 30 orang anggota kelompok tani. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan mitra dalam mengolah limbah organik menjadi eco-enzyme serta mampu mengaplikasikannya pada lahan pertanian. Program ini telah berhasil mendorong kemandirian petani dalam penyediaan pupuk organik cair, mengurangi ketergantungan pada bahan kimia, serta mendukung terciptanya sistem pertanian berkelanjutan yang ramah lingkungan.]]>
