ABSTRACT = {The study compared solar dryers with hot air from a heat exchanger double furnace during the drying of white turmeric. Solar drying is the process of 
drying the product in the sun. The hot air dryer consists of two furnaces with heat exchanger pipes and a drying chamber with six vertical shelves. 
During the test, the use of rice husk energy in a constant amount of 35 kg. Temperature and drying rate are higher in hot air dryers. Tests carried out 
for 420 minutes resulted in a change in moisture content from 88% to 35.88% and an average temperature of 30.91oC in solar drying. For hot air, it 
was 2.7% at an average temperature of 73.65-119.12oC. The distribution of the average drying temperature on shelves 1 (bottom shelf), 2, 3, 4, 5, and 
6 (top shelf) are 119.12oC, 104.99oC, 93.24oC, 79.99oC, 74.69oC, and 73.65oC. Dryer efficiency reached 32.81% at the beginning and 4.06% at the 
end. At the initial drying, efficiency occurs very high because the energy absorbed by the white turmeric from the dryer is very high. During the drying 
process, there is a decrease in efficiency because the energy absorbed by white turmeric decreases due to reduced moisture content.},
