Shorting Machine Trainer Based on Programmable Logic Controller OMRON as Learning Media for Controller and Robotics Subjects

Abstract

The purpose of making a Programmable Logic Controller-based shorting machine trainer is as a development of learning media in schools related to control and robotics subjects. The method used in the development of this media is the Research and Development Method. The stages carried out are (1) potential and problems, (2) data collection, (3) product design, (4) design validation, (5) design revision, (6) product trial, (7) product revision . This trainer consists of 14 components namely Programmable Logic Controller, Power Supply, Push Button, Pilot Lamp, emergency button, infrared sensor, 24V DC motor, inductive proximity sensor, capacitive proximity sensor, Mini Circuit Breaker, relay, solenoid valve, pneumatic cylinder, and water filters. The results of the trainer content validity test as a whole get an assessment of 0.13 included in the very valid category. Meanwhile, for construct validation testing, a rating of 0.38 was included in the very valid category. The results of the trainer practicality test as a whole which were assessed by students obtained a practicality percentage rating of 90.83 included in the very practical category.
