<![CDATA[Vegetable waste, a form of organic matter, poses a risk of environmental pollution when not properly managed. This waste is produced in substantial quantities by communities and can contribute to environmental degradation. A viable solution to this issue is the conversion of vegetable waste into organic fertilizer through fermentation. This community service initiative was designed to enhance participants' knowledge and skills in producing organic fertilizer from vegetable waste and promoting eco-friendly waste management practices. The activity was conducted at the Universitas Sulawesi Barat Greenhouse and involved students from the 2023 cohort of the Agroecotechnology Study Program. The methodology included demonstrations followed by practical sessions, which encompassed the preparation of tools and materials, the preparation of the EM4 bioactivator, the mixing process, and fermentation. The findings indicate that participants effectively comprehended and executed the steps necessary for organic fertilizer production. An improvement in participants' knowledge was demonstrated by evaluation results, with the average pre-test score increasing from 2.00 to 4.18 in the post-test. In addition to knowledge enhancement, the training provided participants with technical skills in organic waste processing and heightened their awareness of the importance of the "reduce, reuse, and recycle" principles in supporting sustainable agriculture. Thus, training on the production of organic fertilizer from vegetable waste has proven to be an effective educational tool and a strategy for sustainable environmental management.]]>
