This project aims to design, build and test the control unit of the drying air conditions for banana. By the climate control unit can adjust the temperature, speed and relative humidity of the air by all roasted banana-ball test that has a variable air temperature 60, 70 and 80 3.6 m/s speed and 9.7 m/s with increased humidity from one. Banana with initial humidity + 23.36% dry basis _ 281.78 done drying until the final humidity + 3.57% dry basis 41.19 _ found that the temperature rise. Result in reduced drying time-use in all circumstances.It found that 9.7 m/s speed when the air temperature increases drying rate has resulted in increased value and power consumption have more value. When compared to the 3.6 m/s speed, it can be seen that the rate of power consumption is less than. Section, it has a value of relative humidity decreases more slowly and take longer than the 9.7 m/s speed and, after comparing the rate of drying at a temperature of 70 m/s speed for spray 9.7 has less energy value, that is 0.62 0.42 k _ + Wh/
