Analysis of Upper Body Working Posture among Minimarket Cashiers Using the Rapid Upper Limb Assessment (RULA) Method

Abstract

In the scientific field of ergonomics there is one study that studies work posture using one of the commonly used methods, namely Rapid Upper Limb Assessment (RULA), the study discusses the analysis of upper human body posture when working. In this study, we analyzed body posture when working in a job as a minimarket cashier, this analysis was carried out using the Rapid Upper Limb Assessment (RULA) method in order to find out whether the work causes Musculoskeletal disorders (MSDs). Health problems due to doing a job is something that will always be experienced. Lack of understanding of how to properly interact between humans and the work environment is a major factor in the emergence of these risks. One job that is commonly done and has a high probability of adverse risks is the Indomaret cashier employee. RULA (Rapid Upper Limb Assessment) is a method that aims to calculate and analyze the upper human body. The output of this method is a decision level that shows the urgency of the action needed. In the calculation results using the RULA method in this study, there is no significant difference in the decision weight. The final conclusion is to make immediate improvements and evaluations on the weight of high posture. Evaluation and improvement are recommended for the design and layout of the workplace because the posture of employees is influenced by the form of design, layout, and the length of working hours itself. It is hoped that the results of this study can be used as a way to improve employee health and avoid the adverse risks caused.
