This study aimed to analyze the effect of Moringa (Moringa oleifera) leaf addition on the nutrient content of liquid organic fertilizer (LOF) derived from cattle manure, and to evaluate farmers' acceptance through an extension program. Using a Completely Randomized Design with four treatments (0, 50, 100, and 150 g Moringa leaves per 3 kg manure) and four replications, the mixtures were fermented for 29 days. Results showed that Moringa supplementation significantly increased nitrogen (N), phosphorus (P), and potassium (K) levels. Treatment P3 (150 g leaves) yielded the highest nutrient content (N: 0.49%, P: 3.73%, K: 3.22%), with P and K meeting national fertilizer standards. The accompanying extension program significantly improved farmers' knowledge, skills, and attitudes, with an effectiveness rate of 71.98%. These findings demonstrate that Moringa-enriched LOF is a viable, sustainable fertilizer option, well-received by farmers through participatory training
