Shallot and garlic peel waste are household and market organic wastes that are relatively abundant; however, their utilization as agricultural production inputs remains limited. This community service activity aimed to improve the literacy and skills of the target community in processing onion peel waste into an organic plant growth regulator (PGR) through simple fermentation techniques. The program was conducted using participatory educational methods, product-making demonstrations, packaging practices, and evaluations employing pre-test and post-test instruments administered to 40 participants from the Mandiri Farmer Group in Mojoagung Village, Nganjuk Regency. The core materials included concepts of organic waste, the potential bioactive compounds contained in onion peels, fermentation procedures using yeast, dilution guidelines, and safe application methods for plants. The activity resulted in a prototype of liquid organic PGR packaged in 1-liter containers, a product label design, and usage guidelines recommending the dilution of 10 ml of PGR solution in 1 liter of water before application to planting media or root zones. Quantitative descriptive evaluation showed an average increase of 49.7% in participants’ understanding based on comparisons between pre-test and post-test scores. Educational activities on the utilization of onion peel waste into organic PGR have the potential to become an appropriate, economical, environmentally friendly technology relevant to supporting sustainable agriculture at the household and farmer-group levels.
Limbah kulit bawang merah dan bawang putih merupakan limbah organik rumah tangga dan pasar yang jumlahnya relatif banyak, tetapi pemanfaatannya sebagai sarana produksi pertanian masih terbatas. Kegiatan pengabdian ini bertujuan meningkatkan literasi dan keterampilan masyarakat sasaran dalam mengolah limbah kulit bawang menjadi zat pengatur tumbuh (ZPT) organik berbasis fermentasi sederhana. Metode kegiatan disusun dalam bentuk edukasi partisipatif, demonstrasi pembuatan produk, praktik pengemasan, dan evaluasi menggunakan instrumen pre-test dan post-test terhadap 40 peserta Kelompok Tani Mandiri Desa Mojoagung, Kabupaten Nganjuk. Materi inti meliputi konsep limbah organik, potensi senyawa bioaktif kulit bawang, prosedur fermentasi menggunakan ragi, aturan pengenceran, serta keamanan aplikasi pada tanaman. Hasil kegiatan menghasilkan prototipe ZPT organik cair berkemasan 1 liter, rancangan label produk, dan panduan penggunaan 10 ml larutan ZPT yang diencerkan dalam 1 liter air sebelum diaplikasikan pada media tanam atau area perakaran. Evaluasi secara kuantitatif deskriptif menunjukkan rata-rata peningkatan pemahaman peserta sebesar 49,7% berdasarkan perbandingan skor pre-test dan post-test. Edukasi pemanfaatan limbah kulit bawang menjadi ZPT organik berpotensi menjadi teknologi tepat guna yang ekonomis, ramah lingkungan, dan relevan untuk mendukung pertanian berkelanjutan berbasis rumah tangga atau kelompok tani.
