Abstract

The purpose of this project is to determine the risk factors that contribute to discomfort and muscle fatigue during prolonged standing for train passengers. Observations have been conducted on 19 female respondents with the Body Mass Index (BMI) either overweight or obese which higher than normal. This research limited for women who are using KTM Komuter because the route and time taken for KTM can be up to two hours and above compare to other train facilities. Variations of body postures observed from respondents frequent train user were characterized and analyzed by using CATIA V5 software. A lifelike manikin was inserted and edited based on the anthropometric data collected from the respondents. Then, the human activity analysis was simulated by using CATIA V5 software. In this project, there are four finalized body postures of the respondents were taken and analyzed by using Rapid Upper Limb Assessment (RULA) method in CATIA V5. The result of the study shows that three postures need further investigation and another one is harmful and need to change immediately to reduce ergonomic risk factor. Based on the RULA scores, the ideal body postures while riding train in a long period of time was proposed to minimize the risk from suffer Musculoskeletal Disorders (MSD). The pain experienced by the respondents can be preventing by changing body posture while in the train.
