PT XYZ requires mechanical power and physical work of the operator in the process of producing plastic bottles. However, human labor has physical limitations when doing excessive activity. The risk of injury and work accident that will occur is quite high if left unchecked. One of them is work injury experienced by the operator in production activities, namely, musculoskeletal disorders, hand injuries and back pain. This is due to work activities carried out repeatedly and resulting in injuries, as well as decreased work productivity. Therefore, this research will try to find a solution to the problem by measuring the risk level using the cumulative trauma disorders (CTD) risk index approach. The results of this study indicate that injury levels were obtained on three main factors and one additional factor, including: Frequency Factor (1.98), Posture Factor (0.9) and Force Factor (3,441), and Miscellaneous Factor (1). Then, a CTD Risk Index of 1.996 was obtained. This shows that, CTD Risk Index produces a cumulative risk level> 1. This can result in the risk of cumulative injury to the operator at the work station, which can lead to muscle injury. Thus, the solution of the problem from this research is that there is a need for rest and repair work station layout, so that the operator can work with good posture and prevent the risk of work, muscle fatigue resulting in Cumulative Trauma Disorders (CTDs).
