Analysis Workstation in Manufacturing Industry using Occupational Repetitive Action (OCRA) Index Method to Reduce Risk of Work-Related Musculoskeletal Disorder

According to analysis of Global Burden Disease (GDB) 2019 data, approximately 1.71 billion people have musculoskeletal disorder (MSDs) worldwide. It could cause constant pain and limitations in mobility, dexterity, reducing people’s ability work. Musculoskeletal disorders can be caused by repetitive heavy work activities. On Hub 2/3 station, production is carried out machining processes using CNC machines, drilling machines tapping with predetermined target outputs. In this process, there are actions which risk disorders. By the OCRA method calculating Index value, operator 1 red zone, then 2 3 yellow zone means conditions at workstations must improved. The objective paper analyze order minimize for each operator. proposed improvement given fulfill objectives paper. results calculations assumption that all improvements applied smaller than previous reduced.
