<![CDATA[Organic waste from siwalan processing in Ngujuran Village, Bancar Subdistrict, Tuban Regency has not been optimally utilized, thus potentially causing environmental pollution. This community service activity aims to improve the knowledge and skills of farmers in processing siwalan fruit peel waste into liquid organic fertilizer (LOF). The applied methods included socialization, demonstration-based training, and evaluation using pre-test and post-test instruments. The results showed increased participants' knowledge and technical skills in making LOF from siwalan waste. This activity produced two main outputs: LOF products and a simple fermentation tool innovation called GALAKSI (Galon Airlock Kulit Siwalan/Siwalan Peel Airlock Gallon), which the community can replicate independently. This program has the potential to support community-based agricultural waste management, reduce dependence on chemical fertilizers, and encourage the realization of a sustainable and environmentally friendly agricultural system.
