The Analysis of Employees’ Work Posture by using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA)

Abstract

Abstract This study aims to analyze the work posture of employees by using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods. In this study, the angle of the employee was calculated, and the results showed that on the body part B, the angle of the back movement is 77º flexion, the neck is 18º extension, and the leg is 39º, while the leg is not uniformly supported. One of the body parts, such as the upper arm is formed an angle of 65 ° flexion, the forearm is 13 ° flexion, the wrist is 0 ° flexion, and the wrist is in the intermediate range of rotation. Based on the results of RULA, a grand score is 7, categorized as Action level 4. Meanwhile, based on the results of REBA, the grand score obtained is 11, and also categorized as Action level 4. Based on the calculation of work posture using RULA and REBA methods, it revealed that the operator’s work posture has a high-level and dangerous risk. Therefore, the operator needs to immediately improve his work posture. In addition, due to the lifting position that was started with no squatting position, it causes waist injures, since it becomes the lift’s pedestal.
