Conventional melon cultivation often faces challenges such as limited productive land and high input costs driven by dependency on synthetic chemical fertilizers, which potentially degrade soil fertility. This community service program aims to enhance the knowledge and skills of residents in Biting Hamlet, Seloliman, in implementing sustainable melon cultivation independently by utilizing alternative used gallon containers and applying leaf-based Liquid Organic Fertilizer (LOF) and goat manure maceration. The program methods included theoretical socialization, practical demonstrations of organic fertilizer production, and field-based technical guidance. Evaluation results using a Likert scale questionnaire demonstrated significant program success, with the majority of participants (86.7%) finding the practical demonstrations highly accessible, 60% experiencing a drastic increase in technical knowledge, and most participants (80%) expressing high interest in applying these methods in their own home gardens. It can be concluded that this integrative approach effectively provides a solution for agricultural cost efficiency, optimizes limited land use, and supports soil ecological sustainability at the household level.
