Abstract

Water is essential to human life because it is the main foundation for survival. The service aims to collaborate with Gemulak Sayung Village, Demak Regency, and Jawa Tengah coastal communities to obtain a decent drinking water supply from rainwater treatment using electrolysis science and technology. The stages of service implementation were carried out through observation, training in making simple electrolysis equipment, monitoring, and evaluation. On observation, the problem was obtained: water availability is still minimal for consumption. Implement training in making electrolysis equipment that can be applied in their homes. Monitoring and evaluation are carried out to ensure the sustainability of the service implementation. The service results showed that participants learned about the benefits of rainwater and simple processing technology using electrolysis to produce electrolyzed water in alkaline and acidic water. 95% of participants wanted the service process to be continued because it benefited the Gemulak Village, Sayung, and Demak communities.

Abstract

Tugu Village in Demak Regency frequently experiences disasters such as coastal erosion and inundation due to tidal activities and the reclamation of Marina Beach in Semarang, which borders Sayung District. These conditions negatively impact the local economy, necessitating a solution to enhance food self-sufficiency. One approach taken is the cultivation of catfish in barrels (budikdamber) using an aquaponic system to grow water spinach, supported by the Internet of Things (IoT). The target audience for this community service activity is the women in Tugu Village affected by flooding. The program was implemented in five stages: observation and coordination, socialization, training, technology application, mentoring, and evaluation. Evaluation was conducted using pre-test and post-test instruments. Before the program, participants' understanding of aquaponic budikdamber was only 32.5%, but after the program, it increased sharply to 95%. Participants' understanding of pellet-making also saw a significant increase, from 10% before the program to 90% afterward. This data indicates that the program implementation successfully improved participants' understanding.
