Abstract

The natural process of drying seaweed takes a long time depending on sunlight. In addition, the effects of weather, seasons, and the turn of day and night make this process more limited and unable to fully control. Post-harvest seaweed has a moisture content of about 92.5% and takes a long time in the drying process.The design of dryer consists of a solar collector equipped with an exhaust fan which serves to accelerate the occurrence of forced heat convection from the collector and the drying chamber and the air heating system using a solar collector by using rock media as a rock bed heat storage material. This paper investigated the drying process by using solar-collectors, biomass, and hybrid to dry seaweed. The research method is done in the testing activity using prototype solar collector unit using rock bed system arranged on solar collector. The results obtained by testing the solar collector heat source at an average solar radiation intensity of 957.48W/m2 average collector temperature of 79.53oC shows that the solar collector is functioning maximally by generating a drying room temperature. An average of 52.89oC indicates a spreading of heat from the solar collector to every drying tray already fulfilled for the process of drying the seaweed. The average of drying rate has 0.0123 gram/sec for 2 days, 0.0569 grams/sec for 400 minutes, and 0.0893 grams/sec for 300 minutes for testing with solar collector, biomass and hybrid respectively.The efficiency rate of drying is 4.48%, 10.31%, and 13.36% for the solar collector, biomass, and hybrid respectively.
