solar power dryer, sun-dried fish, solar cells


This research presents the development of a solar dryer that combines solar heat energy with heat energy from a heater to increase the drying temperature when the water activity value is less than 85% of the fish weight. By using an Arduino load cell weighing device, it sends an alarm signal when the production process is complete. The structure of the machine consists of a 550 W solar panel, a 300 W heater, an Arduino load cell, and a humidity and temperature controller. The capacity is
4 kg/time. The test will use sun-dried fish as raw material and employ temperatures between 50-60 °C divided into three production testing methods. From the test, it was found that natural drying. The production time is 5 hrs/time, drying by solar dryer takes 3.5 hrs/time and drying in a solar dryer with a solar cell takes 3 hrs./ production time. In summary, drying sun-dried catfish with a solar dryer combined with solar cells takes the least production time. However, solar dryers have the most break-even point.
