Sambiganen Village has significant potential in the coffee plantation sector; however, its management remains suboptimal due to farmers' limited knowledge of proper cultivation techniques, particularly regarding strategic planting locations, pruning, and pest control. In addition, the village faces challenges related to the accumulation of household and garden organic waste, as well as a lack of learning assistance for elementary school-age children. This community service program addressed these three issues through an integrated approach: (1) extension services on coffee cultivation; (2) training in producing Local Microorganisms (MOL), which serve two functions once fermentation succeeds direct application to planting media as a liquid bio-fertilizer, and use as a natural bioactivator that replaces EM4 in producing liquid and solid composted fertilizer using a modified, filter-equipped drum; and (3) a creative learning class for elementary school-age children. The program used a Community Based Research (CBR) approach consisting of four stages: laying the foundation, planning, information gathering, and acting on findings, in partnership with the Agricultural Extension Officer (PPL) of Ngrayun Sub-district. Results showed increased farmer understanding of coffee cultivation techniques, growing community self-reliance in organic waste processing, and improved learning engagement among children.
