The tofu production process and material handling of the factory are done manually by using manpower. In soybean mill and washery subdivision, the workers often do spinning, bowing, and lifting soybean up in a high repeating frequency. Besides, the work activity dominated by standing work position. If this static position is kept in a long time, it will cause a complaint of wrist, arm, back, shoulder, neck, and waist-ache which usually called by MSDs. This research aims to identify and to evaluate the work body position of MMH which has a MSDs risk, so that the researcher design a rehabilitative of work posture using REBA approach.
