<![CDATA[Community service is a program designed to enhance community knowledge and skills in processing catfish aquaculture wastewater into liquid organic fertilizer (LOF) by utilizing pond wastewater and shrimp shell soaking water. This program includes field observation, socialization, demonstrations of liquid organic fertilizer production, and community assistance during the fermentation process, as well as the environmentally friendly utilization of organic waste. The program is intended to increase public awareness that catfish farming wastewater and shrimp shell waste have the potential to be utilized as raw materials for liquid organic fertilizer, thereby supporting the implementation of a circular economy within the community. The objective of this community service activity is to improve community knowledge, skills, and awareness in managing organic waste into value-added products while reducing environmental pollution. The method employed is technology transfer using a participatory approach, consisting of observation, socialization, demonstration, and evaluation stages. The results showed that participants gained a better understanding of the liquid organic fertilizer production process, acquired practical skills in converting aquaculture waste into alternative fertilizer, and developed greater awareness of the importance of sustainable waste management. This community service program is expected to promote community self-reliance in utilizing organic waste, increase its economic value, and support environmental sustainability.]]>
