Abstract: The hybrid sun drying method combines sun drying with additional heating, namely LPG. So that the drying process can take place more quickly and effectively. The three drying methods that will be compared are Open Sun drying, solar dryers, and solar hybrids. The open sun drying operation is carried out using only direct sunlight. The solar drying operation was carried out using a solar dryer without additional heating, while the drying operation with a hybrid solar dryer varied the drying temperature at 40, 50 and 60 °C. The results showed that the average moisture content of corn grains was 13.95% for 10.5 hours, 13.75% for 6 hours, 13.65% for 7 hours, 13.45% for 5 hours, and 13.65 % for 4.5 hours in Open Sun drying, drying without additional sunlight. heater, and solar drying hybrid with temperature variables of 40, 50 and 60oC. The average drying rates were 0.212 g/minute, 0.364 g/minute, 0.318 g/minute, 0.439 g/minute and 0.477 g/minute. The results of the thin layer modeling show that the Two Term model is the most accurate and suitable model for describing the drying characteristics of corn grains for all variables.
