ABSTRACT Pranan Village has great potential in water guava production, but its waste is often unused. This community service aims to enhance farmers’ knowledge through training on producing liquid organic fertilizer (LOF) from water guava waste. The methods include socialization, demonstration, and hands-on practice with pretest and posttest evaluation. Results showed an increase in participants’ understanding, with average scores rising from 51 to 84. The program successfully improved farmers’ skills and encouraged sustainable utilization of water guava waste. Keywords: Liquid Organic Fertilizer, Water Guava Waste, Farmer Group.
