Abstract
PT. SMC is a filter trading company that involves business processes such as inventory, packing, and delivery. Manual material handling activities in the packing process are considered non-ergonomic and can lead to musculoskeletal disorders. One of the packing process activities is plastic wrapping on crates, in which workers carry 12 kg of plastic rolls around a 120×120×150 cm crate, starting from a bending position and lifting the plastic roll to a standing position. The goal of this study was to analyze and improve the wrapping process in terms of ergonomics and productivity. To assess the condition of activities, the Nordic Body Map and Rapid Entire Body Assessment (REBA) methods were used. In addition, a plastic wrapping tool is designed to help the worker in packing activities, and the Quality Function Deployment (QFD) method was used to develop the design process. According to the results of the nordic body map data, many workers have a complaint of pain in the waist and right hand. Using the REBA assessment for the existing condition was obtained the risk level of the lower position was very high, the risk level of the middle position and the upper position were high, while the output of the wrapping processes was 19 pallets per day. Three tool designs were developed, and the plastic wrapping trolley was selected as the best design. After using tools, the research shows that the plastic wrapping procedure in. PT. SMC is classified as non-ergonomic, causing a high risk of harm to the waist and right hand. By using the quality function deployment approach, a wrapping trolley is chosen to be manufactured, and the end REBA value is 3, indicating a low risk level. Another benefit shows that, there was an increase in manufacturing output specifically from 19 pallets/day to 37 pallets/day. © School of Engineering, Taylor’s University.
