Ergonomic design improvement of plastic-waste processing machine based on posture analysis

Indonesia, as one of the world's largest population countries, is facing several population-related problems, one of which is an emerging plastic-waste issue. It is predicted that plastic-waste in Indonesia continues to increase by at least 10% every year if not managed properly. A plastic-waste processing machine is, therefore, designed for chopping and melting plastic-waste in an integrated system. However, operators often suffer from pain when operating the machine for its unergonomic design. An analysis using NBM and RULA method, hence, is needed so that working postures complained by the operators can be identified and assessed in order to design a more ergonomic Creatics 2.0 machine using CATIA software and based on anthropometric data. After analyzing and redesigning Creatics, there are several size differences between the new and preceding versions of Creatics in order to create a more ergonomic design of the machine. so that it can reduce the risk that is on the Creatics.
