<![CDATA[Abstract: This community service program aimed to enhance the capacity of the Karyo Tomo Farmer Group (Poktan) in Sumberharjo Village, Pacitan District, through the application of an organic waste shredding machine and the implementation of refugia plants to support sustainable agriculture. The partner’s problems included suboptimal utilization of organic waste, limited shredding technology, the absence of refugia, and limited financial management and marketing capabilities. The program was conducted from June to August 2026 through surveys, socialization, training, technology application, refuge planting, mentoring, and evaluation. A shredder with a capacity of 100 kg/hour and a six-blade rotary cutter was used to process waste into raw material for compost and liquid organic fertilizer (LOF) through aerobic composting with EM4/MOL bioactivators. A total of 40 members were trained and became capable of producing compost and LOF that met the standards (C/N ratio of 15–20, moisture content of 30–40%), with 3–6 members serving as machine operators. Three hundred refugia seedlings (sunflower, cosmos caudatus, and marigold) were planted on a 1,000 m² demonstration plot as habitat for natural enemies of pests. The program also produced a digital financial recording system based on Excel and expanded marketing through social media. The impacts included improved skills and independence among members, reduced waste disposal, new business opportunities in compost and LOF production, and increased awareness of natural pest control. This technology is projected to reduce chemical fertilizer costs by 40–50% and increase the selling price of compost from IDR 500–800/kg to IDR 2,000–3,000/kg, indicating the development of the partner’s initial capacity toward independent and sustainable organic farming. Keywords: chopping machine; organic waste; farmer groups; refugia; organic fertilizer; sustainable agriculture Abstrak: Kegiatan pengabdian ini bertujuan meningkatkan kapasitas Kelompok Tani (Poktan) Karyo Tomo, Desa Sumberharjo, Kecamatan Pacitan, melalui penerapan mesin pencacah limbah organik dan tanaman refugia untuk mendukung pertanian berkelanjutan. Permasalahan mitra meliputi belum optimalnya pemanfaatan limbah organik, keterbatasan teknologi pencacahan, belum diterapkannya refugia, serta keterbatasan pengelolaan keuangan dan pemasaran. Kegiatan dilaksanakan pada Juni-Agustus 2026 melalui survei, sosialisasi, pelatihan, penerapan teknologi, penanaman refugia, pendampingan, dan evaluasi. Mesin pencacah berkapasitas 100 kg/jam dengan pisau rotary enam mata digunakan untuk mengolah limbah menjadi bahan baku kompos dan pupuk organik cair (POC) melalui pengomposan aerobik berbioaktivator EM4/MOL. Sebanyak 40 anggota dilatih dan mampu memproduksi kompos-POC sesuai standar (C/N 15-20, kadar air 30-40%), dengan 3-6 anggota sebagai operator mesin. Refugia (bunga matahari, kenikir, marigold) sebanyak 300 bibit ditanam pada demplot 1.000 m² sebagai habitat musuh alami hama. Program juga menghasilkan pencatatan keuangan digital berbasis Excel dan perluasan pemasaran melalui media sosial. Dampaknya mencakup meningkatnya keterampilan dan kemandirian anggota, berkurangnya limbah terbuang, terbukanya peluang usaha kompos-POC, serta tumbuhnya kesadaran pengendalian hama alami. Teknologi ini diproyeksikan menekan biaya pupuk kimia 40-50% dan meningkatkan nilai jual kompos dari Rp500-800/kg menjadi Rp2.000-3.000/kg, menunjukkan terbentuknya kapasitas awal mitra menuju pertanian organik yang mandiri dan berkelanjutan.
