Application of REBA and QEC Methods in Redesigning Clamping Workstations to Enhance Ergonomic Performance

This study focuses on redesigning the work platform height for workpiece tightening activities at PT. Xyz, utilizing the Rapid Entire Body Assessment (REBA) and Quick Exposure Check (QEC) methods to assess the risk level of the activity.The results from REBA indicated a high-risk score of 10, while the QEC showed a 61% exposure score, confirming the need for immediate improvements.Based on the analysis of anthropometric data from workers at the CNC FH8800 workstation, the optimal work platform height was determined to be 64.3 cm, whereas the current platform height is 120 cm.A reduction of 55.7 cm is necessary to achieve an ergonomic design, which is expected to reduce operator fatigue and increase productivity.This study demonstrates how ergonomic adjustments based on anthropometric data can improve work conditions and operational efficiency.
