Work posture analysis of gamelan craft center workers using quick methods of ergonomic risk assessment

Abstract

Gamelan craft center in Ponorogo Regency has many hazard factors and risks, one of which is ergonomic risk factors. Workers do work with bent postures, awkward postures, and frequent repetitive movements for a long time. This research aims to analyze the work posture of gamelan craft center workers using quick methods of ergonomic risk assessment. This research used the observational analytical study. Analysis of the work posture by using three methods are Rapid Entire Body Assessment (REBA), Rapid Upper Limb Assessment (RULA) and Quick Exposure Checklist (QEC). Eight jobs were selected are divided into two task elements: the dominant task and risky task. Analysis of the research data using the Friedman non-parametric test. The result of work posture analysis shows that the final score in the three methods gets a high-risk level that is 56.25% (REBA), 43.75% (RULA), and 62.50% (QEC). Friedman test results showed the value of Chi-Square = 13.630, and the significant score is 0.003 (p < 0.05). So it can be concluded that the three ergonomic risk assessment methods have different effectiveness. Quick Exposure Check (QEC) is the best method among all three methods for the ergonomic risk assessment of gamelan center workers.
