Model Pengolahan Limbah Organik menjadi Eco-Enzyme dan Pupuk Organik di Desa Oelnasi, Kecamatan Kupang Tengah, Kabupaten Kupang

Household organic waste that is burned or discarded carelessly pollutes the environment, yet it can be turned into useful products. This community service aimed to improve the knowledge of residents of Oelnasi Village, Kupang Tengah District, Kupang Regency, about an integrated model that processes organic waste into eco-enzyme, liquid fertilizer, compost, and solid organic fertilizer (pupuk organik padat). Fifty participants, mostly farmers from women’s groups (PKK), micro-business groups, and village representatives, took part in a pretest, material delivery, demonstration and hands-on practice, and a posttest using a 40-statement, five-point Likert questionnaire. The mean total score rose from 79.46 to 160.46 out of 200 (p < 0.001; paired t-test and Wilcoxon test), all 50 participants improved, and the N-gain was 0.67 (moderate). The largest gains were in liquid fertilizer use (0.80) and composting (0.76), while interest in applying the products remained lowest (mean 3.30), so follow-up mentoring and demonstration plots are needed.
