Evaluasi Ergonomi untuk Mengurangi Muskuloskeletal Disorders Menggunakan Metode Novel Ergonomic Postural Assessment ( NERPA) dan Work Ergonomic Risk Assessment (WERA) (Studi Kasus: UKM Cipta Mandiri, Sidowayah, Polanharjo, Klaten)

Musculoskeletal injury is one of the work accidents that are often experienced by workers because of the wrong posture when doing work. Cipta Mandiri is a small business that produces barecore. The process of making barecore in Cipta Mandiri still uses human power so that it creates a lot of unnatural work postures and causes workers to have a health complaint about musculoskeletal disorder.This study uses the Work Ergonomic Risk Assessment (WERA) and Novel Ergonomic Postural Assessment (NERPA) methods to determine how much risk is posed by the posture of the activities carried out by workers. The results of calculations using the two methods show that of the 9 work stations studied were 12 work activities, obtained a medium score on the WERA method, while there were 3 activities that got a score of 7, 1 activity with a score of 6, 2 activities with a score of 5, 3 activities with scores 4, 3 activities with a score of 3 on the NERPA method. The proposal that can be given is the procurement of tools in the form of workpiece containers and changing work activities at the related work stations. Keywords : Ergonomic, MSDs, WERA, NERPA, OH
