Musculoskeletal Disorder (MDSs) is a real problem in terms of ergonomics. MSD is a muscle/pain disorder which is frequently undergone by operators after doing work, e.g. in the press line of a printing company. Some activities in press line are lifting books, reaching out the engine levers, and turning the engine levers. Many MSDs are undergone by operators, such as aches in the upper arms, hands, feet, and back. This is caused by excessive burdens and wrong posture when doing work. This study is aimed to compare the assessment results of operators’ body posture by using OCRA and JSI methods. OCRA (Occupational Repetitive Action) Index is a method used to evaluate and analyze a job. Meanwhile, Job Strain Index (JSI) is a method used to estimate the risk of pain in the upper body. Evaluation is carried out on repetitive activities. Based on the calculation results, the OCRA values obtained are 3.35 for the right hand and 1.13 for the left hand. Meanwhile, JSI value for the right hand is 9 and the left hand is 4.5. The results of the assessment indicate that these activities are categorized as high-risk so and need to be corrected. The author’s recommendation is by adding the number of operators on the press line.
