The continuous use of chemical fertilizers in agricultural systems has led to soil degradation, environmental pollution, and adverse effects on human health. One sustainable solution to reduce dependence on chemical fertilizers is the utilization of agricultural waste as raw material for liquid organic fertilizer (LOF). This activity aimed to enhance farmers' knowledge and skills in producing LOF using locally sourced organic waste through a participatory training approach. The training was conducted in Rawang Subdistrict, Padang City, involving 15 farmers in hands-on practice for LOF production using materials such as banana stems, rice straw, Chromolaena odorata (kirinyu), Leucaena leucocephala (lamtoro), and the EM-4 bioactivator. Evaluation was carried out through pre-tests, post-tests, and field practice observations. The results showed a significant improvement in participants' understanding, with average scores increasing from 45.3 to 82.7. Most participants were also able to independently produce LOF following the taught procedures. This activity demonstrates that hands-on, practice-based training is effective in building farmers' capacity and promoting the use of agricultural waste as an environmentally friendly and sustainable plant nutrient source.
