Clove ( Syzygium aromaticum , syn. Eugenia aromaticum ) is one of the leading commodities in Bali. Before it can be processed into a product, cloves must go through a post-harvest process, namely the drying process to obtain a good quality clove. The purpose of this research was to make a multi-rack clove dryer by controlling temperature and relative air humidity (RH). The drying room is designed to have 3 trays with staggered arrangement to facilitate the circulation of hot air in the drying chamber. The hot air produce from a heater and the air flow will circulate using a fan. The temperature and RH sensors were installed in the drying chamber and connected to a control system that will cut off the flow of hot air from the radiator if the desired temperature and RH were reached. The results showed that the design of the drying machine that has been made can work properly. The hot air produce from the heater can circulate and the heat air on the staggered racks arrangement evenly distributed. The decreasing of clove mass per tray are about 40 percent after drying with the decreasing of clove’s water content about 44 percent.
