Work Posture Evaluation on Ergonomic “Colet” Workbench Design in Batik Coloring Process using Rapid Entire Body Assessment and Nordic Body Map

Abstract

The effort to preserve batik is to maintain the continuity of batik production. Coloring process is one of the LPSRUWDQW SURFHVVHV LQ EDWLN SURGXFWLRQ? ,Q DGGLWLRQ WR WKH G\HLQJ WHFKQLTXH? WKHUH LV D ³FROHW´ WHFKQLTXH LQ EDWLN coloring process. Colet technique is considered an efficient technique in saving coloring dyes. The ³colet´ process is still carried out without standards and does not consider ergonomic aspects. This study aims to analyze the risk level of batik workers posture in ³colet´ technique coloring process. This research is an observational study with data analysis using the Nordic Body Map (NBM) and Rapid Entire Body Assessment (REBA). The measurement of NBM got a score of 35 with body complaints on back, shoulder, arm, and knees, then decreased to NBM Score of 29 after the implementation of workbench. Based on the measurement, the risk level with the initial work posture has a score 9 and 7, which means the posture needs immediate corrective action to prevent occupational diseases. 7KH LPSOHPHQWDWLRQ RI (UJRQRPLF ³&ROHW´ ZRUNEHQFK LV D ZD\ WR LPSURYH ZRUN SRVWXUH so the risk could be decreased, with score 4 both in standing and sitting working position.
