Abstract:
Introduction: Manual lifting and load transfer processes that are not carried out properly will result in over exertion-lifting and carrying, i.e. body tissue damage caused by excessive lifting. One of the work-related diseases caused by this activity is Musculoskeletal Disorders (MSDs), a disorder that occurs in the muscles, nerves, tendons, ligaments, joints, cartilages, or the intervertebral discs. The study aims to find out the picture of ergonomic risk in manual material handling activity and musculoskeletal complaints.
Methods: Data was obtained from two respondents through accidental sampling. The measurement of the lifting index is done with meters and calculated using the formula of the calculation of the lifting index. The instrument for measuring musculoskeletal disorders was the GOTRAK SNI 9011:2021 Questionnaire.
Results: Lifting activities performed by the Hand Add section (LI: 3.054-3.228) and Bagging Off (LI: 3.073-3.470) have a Lifting Index value that is in category > 3 so the interpreted activity has a high risk of causing musculoskeletal complaints. Workers who perform manual material handling activities have high complaints of skeletal and muscle disorders in the upper limbs.
Conclusion: Manual handling activities performed in the industry have a high risk of causing injury. Workers who perform manual material handling activities are known to have high complaints of muscle and muscle disorders in the upper limbs.
