<![CDATA[TPS3R Kalanganyar Village has considerable potential in waste management and Nile tilapia (Oreochromis niloticus) farming. However, limited farming capacity, high feed costs, and restricted marketing access have hindered the optimization of its economic potential. This community service program aimed to strengthen food security by implementing a circular economy-based community empowerment model. The program consisted of developing fish and Black Soldier Fly (BSF) maggot farming infrastructure, implementing digital technologies, and conducting community training and assistance. The program resulted in the construction of two biofloc-based Nile tilapia ponds, one modular maggot cultivation rack, a water quality monitoring system, a digital marketing platform, and an aquaculture learning center. Training provided to 15 TPS3R managers increased participants' knowledge by 58.5%, with an overall satisfaction rate of 87.5%. Economic analysis indicated that the developed aquaculture system has the potential to generate a gross income of approximately IDR 4,320,000 per production cycle, while BSF maggot cultivation could substitute approximately 4.3% of commercial fish feed requirements. These findings demonstrate that integrating circular economy principles with digital technologies can enhance aquaculture capacity and contribute to strengthening community-based food security.]]>
