The continuous use of synthetic chemical fertilizers in Saenam Village, West Miomaffo District, North Central Timor Regency, has led to soil degradation and increased agricultural operational costs. On the other hand, the potential of local organic materials such as household liquid waste in the form of rice washing water has not been optimally utilized. This Community Service Program aims to increase the knowledge, skills, and independence of the Saenam Village community in producing and applying liquid organic fertilizer (LOF) based on local materials. The activity was held on August 7, 2026, attended by 20 participants including village government officials and local farmer groups. The method used was a participatory approach involving preparation, implementation (counseling, technical demonstration, and hands-on practice), as well as mentoring and evaluation phases. The LOF production process utilized rice washing water, molasses, and EM4 activators fermented anaerobically for 14 days. The results showed a significant increase in the community's technical knowledge and skills in processing rice washing water into LOF independently. All participants were able to demonstrate the LOF production workflow from material measuring, mixing, stirring, to setting up the fermentation container. This program successfully introduced an applicable and environmentally friendly appropriate technology.
