Model Designing Work Facilities of Brick Creamers Using Biomechanics Approach at UD. Usaha Muda

Abstract

UD. Usaha Muda is a manufacturing company engaged in the production of bricks, located in Dewantara District, North Aceh Regency. This study aims to redesign work facilities so that they can relieve the forces that occur in each segment of the worker's body and improve work posture. Work activities are carried out in a standing position to print bricks and bend over to move bricks that have been completed to a temporary drying place. This work attitude is not ergonomic or is an unnatural work position that is often caused by work facilities, causing discomfort and pain in body segments. This study begins with the identification of pain complaints with the NBM questionnaire. Furthermore, the calculation of the magnitude of the force that occurs in each segment of the worker's body using a biomechanical approach. The results of the analysis with the NBM questionnaire obtained information on complaints of pain in the largest body segment at the waist. Meanwhile, the results of the force analysis using a biomechanical approach, the greatest value of force in each body segment occurs in the body / waist and thighs. Based on the results of the re-design, the improvement of work facilities with ergonomic principles can reduce the working force on each segment of the body and reduce the risk of muscle complaints by reducing work posture bent on each element of work performed by workers.
