In the fishing system, fishermen in Riau Islands generally use small-scale motorboats and (conventional) fishing gear, one of which is to maintain the freshness of fish using (conventional) techniques. Due to the absence of a durable fish cooling system, fishermen only use containers containing ice blocks to cool the fish so that the fish stays fresh within a few hours. The purpose of the research is to design a control system for automatic fish box cooling with a constant temperature in the hold. This research tool consists of heatsinks, peltier coolers, temperature gauges, waterblock, and pumps. The system device in this study is to use temperature sensors and bluetooth. The sensor readings will be processed using Arduino Uno which is integrated with bluetooth and then sent to the android application. Data in the Android application will be monitored based on the desired temperature (set point).} }
