As one of the renewable energy that can be utilized in various fields, solar energy is a potential energy source considering that Indonesia has a tropical climate. One of the uses of solar energy is in agriculture. Various agricultural commodities need to be dried before further processing. Also in coffee commodities that are being favored by many people nowadays. For this reason, as a solution to the problem of long drying times with weather changes issue, a room is made as a drying medium. By sucking hot air from a 2.576 m2 solar collector using the exhaust, it is expected that heat will be maintained in the space that has been isolated. The 2.4 m2 dryer rack design is made in three trays to make the most of the space. The results of the room that have been made is able to keep the lowest temperature at night at 26.6 °C and the highest temperature at 60.7 °C during the day. The highest average temperature in the room is on the bottom shelf near the hot air source.
