Automation of Waste Treatment on the Washer Machine Based on PLC Control System in the Manufacturing Industry

摘要

This paper presents research conducted in the manufacturing industry, in Indonesia. This manufacturing industry is the manufacturer of valve engine parts or also called valve engines. In the processing of industrial waste, this company cannot manage all its own waste results to the maximum so that it can disrupt the workings of the machine resulting in downtime. In an effort to manage waste and maintain the quality of the machine, we do research to separate waste oil on manual washer machine to extend the period of usage of water washer, which is by making machine waste processing tool automatically based on PLC (Programmable Logic Controller). We use the precipitation method to separate the waste in the water washer. The precipitation method is to allow the mixture of waste oil and water washer within the specified time period, so that the used oil can be drained to the maximum and the water washer can be reused on the manual washer machine. This system works automatically using PLC with the number of Input-Output required as many as 13 addresses. The program created has 2 menus, the manual and automatic menus. Finally, this system has worked automatically, then the washing process becomes faster 2 minutes each washing process. Used oil and water washer that has been deployed does not need to be processed by a waste company so the company only removes used oil and does not need to spend to dispose of waste water. This is because the water washer can be reused by manual washer machine.
