Penjadwalan Waktu Istirahat Optimal Untuk Mengurangi Risiko Musculoskeletal Disorders Berdasarkan OCRA Index
Abstract: Repetitive tasks
carried out by workers of packaging department of mineral water company led to
some complaints of pain and fatigue on a particular body part of the workers,
especially on their upper body part. This study aims to determine risk level of
musculoskeletal disorders with OCRA index and provides optimal break schedule
to reduce the risk level. Based on calculations using the OCRA index method, it
is found that risk of injury to the workers were medium with high level of
risk. Despite small workload of the operators, this may be caused by poor
distribution of rest periods and lengthy working time for highly repetitive
tasks. Improvement proposed in this study is type of work-compliant break time
allocation. Optimal scheduling of which main objective is optimal break time is
eventually obtained by applying enumeration algorithm with integer linear
programming model. Based on OCRA index after improvement, it is clear that the
proposal decreases the risk level of the workers.
