Wiyono Village in Pesawaran Regency is one of the strategic villages in cocoa business development. The poor management of cocoa pod waste has resulted in dirty garden sanitation and many sources of cacao pod rot disease. Lack of knowledge about the utilization of organik waste from cocoa and Trichoderma sp which has the potential as organik fertilizer has become the main topic in the Pengabdian kepada Masyarakat (PKM) activities. The partner's great desire is to make his village a model village, as a clean, healthy and free of waste village through processing organik waste and utilizing Trichoderma as fertilizer. This PKM program aims to develop farmer groups so that they can make organik fertilizer from cocoa plant residues from the garden in the form of leaves, fruit peels and fallen/rotten fruit in partner villages through the composting process. The solution offered is the transfer of technology for making compost organik fertilizer by giving EM4 to speed up the composting process so that it is expected to be able to provide organik fertilizer and make garden sanitation cleaner. The results obtained after the implementation of this PKM are that the Setia Usaha farmer group community is able to produce organik fertilizer with good quality from raw materials for cocoa husk waste and Trichoderma for the needs of their own group or as a side business. The increase in income from the sale of organik fertilizers is not too significant. Knowledge of how to make compost from organik waste raw materials compared to before and after the implementation of PKM increased by 95%
