Abstract

Manual router operators at PT Delapan Intan Mutiara perform tasks that require bending, reaching, and controlling a handheld tool during routine production at this workstation, potentially exposing them to ergonomic risks. This study aimed to identify musculoskeletal complaint levels among operators, determine the body regions contributing most to complaint scores, and assess the risk of one documented working posture. A descriptive quantitative approach was applied to all 13 operators using the Nordic Body Map (NBM) questionnaire, which assessed 28 body regions. One recorded working posture was evaluated using Rapid Entire Body Assessment (REBA), supported by angle measurements from Kinovea software. The total NBM score was 835. The waist contributed the highest score, 41 (4.91%), followed by the back, 39 (4.67%). Both upper arms and both wrists each scored 33 (3.95%). Eight operators (61.5%) were classified as having moderate complaint levels, three (23.1%) high, one (7.7%) very high, and one (7.7%) low. The reported REBA score for the assessed posture was 13, indicating very high postural risk and a need for prompt ergonomic evaluation. However, the load, grip, and activity adjustments require confirmation from field measurements, so this score remains provisional. The findings suggest prioritizing adjustable workbench height, secure material clamps, and tool guides to reduce bending and excessive reaching. This study contributes a practical baseline combining operator-reported complaints with observation of a specific posture, helping the company set improvement priorities. The effectiveness of proposed changes must be tested through follow-up assessments before any reduction in ergonomic risk can be confirmed.
