Abstract
In a power plant unit whose main fuel is coal, there is generally use a belt conveyor installation. This conveyor belt serves to supply coal from the crusher unit to the combustion chamber of the power generation unit. In this study, we discuss a case where the installation of a belt conveyor which was initially only one line was then made a new branch that supplies coal to other power generating units. Equitable capacity distribution and continuity of coal distribution are the main focus of this study. Therefore, a design of automatic control system of coal flow divider on belt conveyor installation was designed. The working principle of this coal flow splitting system is to control the movement of the straight blade plough that directs the flow of coal to each unit at the certain time and continuously. Straight blade plough in the form of steel metal plate with a thickness of about 10 millimeters in which one end is connected to the end of the pneumatic cylinder. Automatic control system of coal flow divider in belt conveyor installation designed using CX-Programmer and CX-Designer applications. CX-Programmer serves to create automatic control logic concepts. While the CX-designer functions to create a Human Machine Interface (HMI), making it easier for operators to control the course of the coal supply process. The results of this study are in the form of control logic lines that can be applied to Programmable Logic Control (PLC) device and Human Machine Interface (HMI) equipment.

Technological advances have covered almost all aspects of life, including the overhaul of conventional systems that involve a lot of human intervention, switching to automated systems that involve less human intervention and being replaced by a series of automatic control devices
Programmable Logic Control (PLC) is one of the devices that increase the reliability of production automation system through inputs such as sensors to detect objects in real time [2]
The step is to create a control system based on Programmable Logic Controllers (PLC) which will regulate the movement of the straight blade plough each time unit alternately and continuously
Summary
Technological advances have covered almost all aspects of life, including the overhaul of conventional systems that involve a lot of human intervention, switching to automated systems that involve less human intervention and being replaced by a series of automatic control devices. PLC is one of the devices that increase the reliability of production automation system through inputs such as sensors to detect objects in real time [2]. PLC is the most widely used automated system devices today in industrial production processes [3] This programming technology can be controlled automatically and can be completed in a short time and has a programmable memory and stores commands-commands to perform special functions. The step is to create a control system based on Programmable Logic Controllers (PLC) which will regulate the movement of the straight blade plough each time unit alternately and continuously This allows the supply of coal to the generating unit and other generating units to be guaranteed
