Application of Participatory Ergonomics to Reduce The Risk of Musculoskeletal Disorders In Hand Stacker and Material Handling Operators Using The Gotrak Method at PT X

Abstract

Mild steel is a building material widely used today because of its lightweight and relatively cheap material. PT X is one of the companies that produces light steel in Bandung. In the light steel production process, there are several jobs, especially in hand stacker and material handling activities, where the workers have poor posture and are less efficient by using two workers, and hand stacker and material handling activities that can cause MuscleShaped Disorders (MSDs). In the process of eliminating and reducing the risk of MSDs in the workplace, the level of MSD risk experienced by workers is calculated using the GOTRAK method. Discussions were also held with PT X to help reduce the level of MSD risk experienced by workers. The tool's design is carried out to help hand stacker and material handling activities reduce the risk level of MSDs and increase their efficiency. For hand stacker activities, training is designed for hand stacker operators and equipped with PPE for hand stacker operators, as well as making SOPs for hand stacker operations. Meanwhile, material handling activities are designed with two aids in the form of shoulder pads and ramps that can help reduce the level of MSDs experienced by workers. Shoulder pad aids can help operators in charge of pushing movements, and ramp aids can relieve the force emitted by the operator due to the acceleration of the hand truck. In using both assistive devices, the risk level of MSDs was reduced to five, and in carrying out material handling activities, only one operator was needed, and no additional assistance personnel were used. Real improvements are hoped to create a safe, comfortable, and productive workplace
