Cinangka District has not yet implemented a system for separating organic and inorganic waste at the household or community level. Therefore, training on the production of organic fertilizer (POC) and compost using a composter is necessary. This activity was held on June 12, 2025, in Kamasan Village, Cinangka District. A follow-up to this fertilizer training was the creation of a tool to measure the NPK content of fertilizers, allowing for the determination of their appropriate use for specific crops. The results of this activity concluded that processing organic waste into organic fertilizer has the following benefits: 1) Reducing the accumulation of organic waste that can pollute the environment; 2) More economical, as it can reduce the cost of purchasing fertilizers and can even be a business opportunity for fertilizer production; 3) Optimal plantation yields are achieved by using organic fertilizers with the appropriate NPK content for the appropriate crop types
