<![CDATA[Seeing the increasing production of corn, it is necessary to provide a dryer using solar energy sources with the concept of a greenhouse effect to improve the quality of corn in Gorontalo. This research aims to design a prototype hybrid-type greenhouse effect dryer with four ventilation chimneys and calculate the corn drying rate using a hybrid-type greenhouse effect dryer with four ventilation chimneys. The method used is analytical and experimental design. The results obtained from this research are the highest shelf temperature, namely on shelf 1 with a temperature of 54 ºc, the final water content produced is 13.2% on shelf 1 and 13.5% on shelf 2, the temperature in the environment can relatively change every day, the type of stone used is river stone where the stone shelf functions as a heat storage device at the bottom of the shelf so that the rate of heat reduction on shelf 2 becomes slower.]]>
