P PT. MTG was a company that produces mechanical gears. To be able to compete with other competitors, PT. MTG continues to maintain the quality of products. However, the performance of workers affect product quality that has been made, the number of customer orders, long hours of work, repetitive bending motion cause workers experienced discomfort, fatigue and even pain in certain body parts. The purpose of this research was to know the level of physical workload, the level of risk of lifting heavy loads manually and provide corrective suggestions to reduced physical workload and improve the work position of operators at PT. MTG. This research focuses on the 11 operatorof shift 1 at Assy Brake Drum & Hub workstation. Stages of the research is identified the part of body that hurt using Nordic Body Map; identified the work position of operator using RULA (Rapid Upper Limb Assessment); measured the heart rate of workers to calculate CVL (Cardiovascular Load), oxygen consumption, energy expenditure and energy consumption; measured the working position to calculate RWL(Recommended Weight Limit)origin, RWLdestination, LI(Lifting Index)origin and LIdestination, spinal muscular force, lift force and moment of force. Nordic Body Map Questionnaire showed that the complaints of the body been hurt is in the back. RULA measurement result are working position in the category less comfortable. The heart rate measurement result is classified in the category of heavy work. CVL measurement results that the operator had a high workload that needs to be repaired. In the calculation of the working position, results of RWL and LI values indicate that work position repair is necessary. The proposed repairs are gived additional break time and stretch the muscles. After implementation, CVL calculation of 56.62% down to 40.49%. Then the oxygen consumption calculation of 1.83 liters / min down to 1.41 liters / min,while the calculation of energy consumption by 5.56 kcal / min down to 3.75 kcal / min. Whilst the second proposed improvement is the addition of a table with wheels. After implementation, the calculation of the LIorigin of 1.13 down to 0.47 and LIdestination from 3 down to 1.07. Spinal muscular force calculations at 5130.1 N down to 1971.1 N and lifting force of 5675.98 N dropped to 2404.48 N also moment of the force on the backs of 461.1 N dropped to 126.1 N. This shows that there has been a decrease in physical workload and improved working position Brake Drum & Hub Assembly operatorsat PT. MTG.
