Drying method principally is the evaporation process of water from the wet material whose the purpose to obtain the product with the certain moisture content. Researcher uses controlling method of PID (Proportional, Integrative, and Derivative) to control the heater in tray dryer unit. This controller controls the room temperature inside the dryer to make it stable so that the dried product can be obtained fast and efficiently. The controlling process of the tray dryer is able to affect the product consists of its temperature, humidity, error, output controller, rising time, the value of proportionality constants (Kp), Integrative constants (Ki) and derivative constants (Kd). The research components consist of transducer in the form of a thermocouple temperature sensor TW-N Pt 100 type K, Humidity DHT-21, microcontroller, and the final controlling element of the heating element and a booster motor which are integrated by software Arduino, then the performance of this controller is tested. Testing result shows that the controlling method of Proportional, Integrative, and Derivative (PID) has a measurement error as much as ± 0.1167 ⁰C, variable interval is about 45 – 70 ⁰C, rising time of 300 seconds, 100 rpm output controller, the value of proportional constants (Kp) is 9.1, Integrative constants (Ki) is 0.3 and Derivative constants (Kp) is 1.8 within the air flux is about 1.047 to 2.36 m/s. The application of temperature controlling system using tray dryer unit produces moisture contents as much as 5-10% so that by this design of temperature controlling system is able to be applied upon the tray dryer unit.
