Computers in the administration department are managed by a job that runs continuously for eight hours. Improper work posture and posture can cause fatigue and discomfort at work. One of the influencing factors is the working posture and body posture during these activities. This study aims to reduce the level of risk gained by performing Rapid Office Strain Assessments (ROSA) and Rapid Entire Body Assessments (REBA) for clerical staff in engineering departments. Posture analysis data processing using the ROSA (Rapid Office Strain Assessment) method found that five of her employees surveyed were at risk levels and needed to be corrected immediately. The Rapid Entire Body Assessment (REBA) method shows that five employees are currently at risk of urgent needs and requirements. Keywords : Ergonomics, Musculoskeletal Disorders, ROSA, REBA 1. Introduction Administrative work is in dire need of computer assistance so that work can be completed quickly and efficiently(Vahdat, 2021). The computers in the administration department are staffed by a continuous eight-hour job. Improper work postures and postures can cause fatigue and discomfort at work. Ergonomic risks that can arise include musculoskeletal disorders. This hypothesis is due to the fact that the management of science and technology occurs mainly with monitors, keyboards, mice, tables and chairs. The work done by workers is generally repetitive and requires good physical fitness. Whenever working in an awkward position strains a body part and can cause injury, fatigue can lead to permanent disability can reduce the occurrence of injuries during work(Loske, et al., 2021). One of the influencing factors is work posture and body posture when doing these activities. This is very important because the writing of student data letters is strongly influenced by employee behavior(Katano, et al., 2021). If one of the working positions used by workers is not ergonomic, they will tire quickly and their level of concentration and precision will be disturbed. The functioning of the faculty of science and technology is a necessary phenomenon, but in most cases the faculty does not pay attention to the needs and concerns of their workers. For this reason, workers often feel dissatisfied with certain parts of their bodies. The average number of absences per month is five, including sick leave and fatigue pensions. This will result in less than optimal service(Wibowo & Mawadati, 2021). Fatigue/injury factors covered in this study are physical factors that cause work accidents at the Registrar's Office of the Faculty of Science and Engineering. Measurement of management work posture is carried out with the help of Rapid Office Strain Assessment (ROSA) and Rapid Entire Body Assessment (REBA)(de Barros, et al., 2022). This method was chosen because it is in accordance with the characteristics of the government which requires coordination in the management of the science and engineering departments. This study aims to reduce the level of risk achieved by conducting a Rapid Office Strain Assessment (ROSA) and a Rapid Systemic Assessment (REBA) for administrative staff in the department of science and technology. After processing work posture analysis data using the Rapid Office Strain Assessment (ROSA) method, it was found that five employees in the survey sample were at a dangerous level of risk and needed to be corrected. The Whole Body Assessment (REBA) method shows that five employees are at
