Design of Ergonomic Bipang Molding Tool to Increase Production of Bipang

Humans are a central point in a work system because basically humans are not only acting as planners and designers of work systems, but also as executors and controllers. Human limitations become a guideline in designing an ergonomic work system, where the focus of ergonomics involves three components, namely humans, machines / equipment and the environment that interact with each other which results in an inseparable work system. This study aims to determine the risk of skeletal muscle injury that is potentially experienced by bipang production operators, especially in bipang grading and filling activities. The method used to analyze the operator's work posture is the quick exposure check (QEC) and rapid entire body assessment (REBA) methods, this research is carried out by direct observation of the research object, filling out the operator and observer questionnaires and conducting literature studies to collect data related to research. Based on the QEC method, the work posture of Bipang IKM employees on the flatten section has an exposure level of 66.67% while slicing bipang has an exposure level of 60.49% which means that further research and changes are needed. While using the REBA method, the bipang flatten activity obtained by the final score is 10, which means it is at a high level and immediate handling is needed, while the bipang slicing production process is at level 2 which means that immediate handling is needed, the position can cause muscle injury so it requires work improvement. By proposing improvements to work facilities so that the bipang flatten and slicing activities are carried out simultaneously, with a more efficient processing time of 10 minutes to 2 minutes and more optimal work productivity. Based on the REBA method, there is an action level 1 which means that the work posture can be accepted and there is no need for improvement. So that the increase in production when using bipang molding tool is 9,572 piece/day.
