Increasing Production Capacity with IoT-based Floating Net Cage Technology for Erorejo Wadaslintang Freshwater Fishermen

In the last decade, the cultivation of floating net cages for freshwater fishermen in the Wadaslintang reservoir in Erorejo has grown significantly. It is currently one of the contributors to freshwater aquaculture production in Wonosobo Regency. This research aims to implement IoT-based portable floating net cage technology to increase the production capacity of freshwater fisheries in Erorejo, Wadaslintang. This research focuses on red Tilapia, striped catfish, and freshwater milkfish. We analyzed the characteristics of fish seeds, cultivation technology, feed supply, and marketing. We used simple random sampling with 50 fishermen respondents in the Wadaslintang reservoir. We implemented three portable floating net cages for four months. The research showed that of the 1,340 floating net cages, 77.5% were used for red tilapia cultivation, and the remaining 20% of striped catfish were used for freshwater milkfish trials. The average production of red Tilapia is 106.74 kg/day/fisherman, striped catfish 16.26 kg/day/fisherman, and freshwater milkfish has not been recorded. Using IoT-based portable floating net cages showed an average increase of 21% in the production of red Tilapia and 18.5% in striped catfish. Future research must examine the reservoir area's spatial suitability with the productivity level.
