Utilization of Printing Plate Waste As Applied Chemistry Learning Media For Using Engraving and Knocking Techniques

Abstract

This study aims to utilize printing plate waste as alternative to making applied chemistry learning media using engraving and knocking techniques. The method includes three stages namely preproduction, production, and postproduction. Activities carried out in preproduction were collecting data through observation, interviews, literature studies, making pattern designs and teaching materials, and preparing tools and materials. The production stage focused on manufacturing the product. The product was hammered using hammer wrapped in paper adhesive and also engraved using CNC lasercutting machine. The postproduction stage included monitoring and evaluation and improvement of research products. The result was a set of learning media consisting of five media made of plates and one stand where media was placed. This learning media can be used in applied chemistry lectures to make it easier for graphic engineering students at Politeknik Negeri Media Kreatif to understand the lessons taught in class.
