PENGGUNAAN HUMAN MACHINE INTERFACE UNTUK SIMULASI PENGOLAHAN MINYAK KELAPA SAWIT

Abstract

Technological developments have brought changes in the industry, the process that was originally
done by humans has turned to the automation system. In this paper the application of the automation
system is carried out on the processing of palm oil. The system is made in the form of a simulation of
an automation system using the Programmable Logic Controller (PLC) and Human Machine
Interface (HMI). Automation of palm oil processing using PLC with the help of Unity Pro XL
software, monitoring processes using HMI with the help of Vijeo Designer Basic software, and analog
input simulated using a potentiometer. PLC receives and processes data from both analog inputs and
from HMI. The process of cooking and extracting palm oil carried out by the PLC is displayed on the
HMI. From the test results, it is known that the PLC can communicate with HMI and HMI can display
the processes that occur in palm oil processing.
