ANALISIS POSTUR KERJA MENGUNAKAN METODE RULA (RAPID UPPERLIMB ASSESMENT) PADA PT. XY

Abstract

PT XY Batam is a heavy equipment company that was founded in 2008. PT XY Batam produces HMS (Hydraulic Minning Shovel) and LMT (Large Minning Truck) heavy equipment types. One of the production processes is assembly which is carried out by assembly operators in a squatting working posture. Based on observations, operators experience pain in certain parts of the body including pain, soreness and tingling. This research is to calculate the posture score of assembly operator workers to find out whether this work posture poses an ergonomic risk. The analytical tool used for this research is the Rapid Upper Limb Assessment (RULA) method which is used to measure worker posture. Measurements are made by taking pictures of the worker's posture directly which will be processed by measuring the angle of the worker's body position. Based on the research results, it is known that the RULA score obtained is high, namely 7, which means it falls into the category that investigation and changes in work posture are needed as soon as possible (urgent). Workers' squatting and bending postures and work that is done repeatedly are at risk of triggering serious back muscle strains such as Cumulative Trauma Disorders, Repetitive Strain Injuries or Musculoskeletal Disorders.
