DEVELOPMENT OF BIOMECHANIC METHODS FOR ERGONOMIC EVALUATION: COMPARISON WITH RULA AND SES METHODS

Various methods have been developed to evaluate workload in everyday life, and various methods of observation have been carried out. But it is still a debate until now. In this journal, the development of biomechanical methods for evaluating workloads which ergonomics will then be compared with the observation method. The observation method used is the SCANIA Ergonomics Standard (SES) and Rapid Upper Limb Assessment (RULA) methods which will be used to assess ergonomic workloads on two simulation workstations such as tightening, loosening, or increasing the number of pipes, and carrying out other actions. Sensors are also used to measure biomechanical data (Inclinometers, Accelerometers, and Goniometers). The results obtained show an assessment of the risk factors of RULA and SES according to the final results using biomechanical methods. However, there is a mismatch in the neck and wrist posture. In conclusion, the biomechanical approach is more appropriate than the observation method, but several risk factors are evaluated by unmeasured observation methods with biomechanical techniques that have been developed.
