Work posture improvement using ergonomic approach decreases subjective disorders of perapen workers on the process of nguwad gamelan in Bali
Keywords:
ergonomic approach, klungkung bali, nguwad trompong, subjective disorders, work postureAbstract
The process of nguwad trompong is still considered as a heavy task for workers because it is still done using ember of the perapen (fireplace) that is exposed in open and unnatural work posture such as bending work posture. Moreover, the heat of the perapen furnace makes the work heavier for the nguwad workers which can make them tired easily and cause musculoskeletal disorders or known as subjective disorders. Thus, an experimental research was conducted using treatment by subject design toward 12 gamelan workers in Klungkung Bali. The intervention was done by improving the workstation so that the bending work posture of the prapen workers was changed into sat naturally and the bending-while-standing work posture of the smiths was changed into straighter standing work posture. Musculoskeletal disorders were measured using NIOSH Nordic Body Map Subjective Filling. The general fatigue was measured using 30 Items Self-Rating Questionnaire Industrial Fatigue Research Committee from Japan Association of Industrial Health.
