Risk Analysis of Upper Limb Musculoskeletal Disorders in Industrial Skin Measurement Workers Using the Assessment of Repetitive Task Method

Abstract

In the leather industry production process in the Piyungan area of Yogyakarta, Indonesia, the operators do a lot of repetitive activities with intensity and frequency of movement for a long time, for 8 hours in a sitting position. Operators measure on average 4700 pieces of leather per day. This leads to fatigue and complaints of musculoskeletal disorders (MSDs). For this reason, research was conducted to measure the level of risk of MSDs and improve them to reduce muscle complaints. This research was conducted experimentally on all skin-cutting operators at companies in the Piyungan area of Yogyakarta. Measurement of the risk level of upper limb musculoskeletal disorders using the Assessment of Repetitive Tasks (ART) method. The data was analyzed based on ART scores obtained, ranging from low, medium, and high risk level scores. The conclusion of the results showed that the risk level of upper limb musculoskeletal disorders in this skin measurement operator included medium and high risk levels on the left and right upper limb operators. Improvements that can be made to reduce the level of risk are improvements to work facilities in the form of chairs, additional short rest periods, and stretching muscles before and after doing work on all skin measurement production operators.
