Abstract
In general, rice farmers in Indonesia still use conventional methods to dry rice, which uses sunlight for a long time depending on the weather and must be in the open. Even though the heat from sunlight is not always stable, it is necessary to innovate to streamline the drying process in a modern and efficient way. Because of this PLC-based rice drying machine prototype was made. The design of the Prototype Control System of the rice drying machine as this final project uses the Nano V.4 Outseal Programmable Logic Controller (PLC) as the main controller. This tool is designed with a rotary dryer type. PLC controls the input signal that is inputted and then processed according to the ladder diagram of the uploaded program. The structure of the control system program consists of 17 line rung, 5 internal timers, 5 internal digital memory, 3 digital input addresses and 1 analog input, and 7 output addresses. PLC output in the form of an actuator that will drive the motor through the VFD as a regulator of the motor rotation speed, flame extinguisher, solenoid valve and blower.
