Drying problems still dominate in some groups of cinnamon farmers, namely the long drying time, changes in weather and climate that often hamper their productivity. So we need a drying tool that is able to solve these problems. Cinnamon bark drying takes 5 to 7 hours to dry. During the drying process, the dryness of the cinnamon bark can be percentaged with a dryness percentage of 22.5%, and the moisture of the cinnamon bark before drying is 18.7%. During the drying of the cinnamon bark, the moisture in the cinnamon bark will change to 11.0% with a capacity of 11.0%. in the 2000 G dryer box, the use of a voltage of 222.5 V, a current of 2.25 A and a power of 505.1 W. It is efficient that using a cinnamon bark dryer box is more efficient than drying using sunlight and depending on weather conditions, then it can be said that the dryer box is more effective.} }
