Abstract
Rail transport is one of the alternative modes of transportation that has become a priority for developing countries to promote environmental, economic, and social well-being in upgrading the quality of urban life. As such, the study that considers the ergonomic risks experienced by passengers while boarding the train is very important to allow passengers to be in a healthy train cabin and not cause temporary unhealthy environment to train passengers. This research examined passenger satisfaction and comfort towards KTM Komuter based on the Ergonomic Risk Factor (ERF) and the health symptoms experienced by train passengers while using this public vehicle. Five dimensions were being investigated; Ergonomic Risk Factor, Musculoskeletal Disorder symptoms, Health symptoms, Passenger Comfort and Passenger Satisfaction. Structured self-administered questionnaires were distributed to the KTM Komuter passengers using the random sampling technique. A quantitative research method, with a questionnaire as an instrument for this research. Usable responses were received from 361 passengers giving a response rate of 90.25 percent. The structural Equation Model (SEM) investigated the relationship between the ERF, health symptoms, passenger comfort, and passenger satisfaction through IBM-SPSS-AMOS version 25.0 software. Apart from that, data collection using a measurement tool was also done to enable data collection for vibration values (the Dytran Model 5313A), noise (Sound Level Meter), and ventilation (Air Quality Meter) in the train cabin. This is to obtain results that are equivalent to the evaluation of the survey questions that have been answered by train passengers based on their own experiences while boarding this train to their destination. Ergonomic risk factors have a significant effect on Musculoskeletal Disorder symptoms, ergonomic risk factors have a significant effect on health symptoms, ergonomic risk factors have a significant indirect effect on passenger comfort, musculoskeletal disorder has a significant effect on passenger comfort, and lastly, health symptom has a significant effect on passenger comfort. Based on the measurement tool result that has been compared with the standard for each ergonomic risk factor, the noise in the train cabin has reached a value of 82.2 dBA while in the gangway from the journey of UKM to Kajang. As for the vibration value, the measurement tool has recorded the highest vibration value reading of 2,2182 m/s2 in the z-direction in the gangway area along the journey from Kajang to Tiroi. Meanwhile, the ventilation value that has been recorded has also exceeded the allowable standard level that is for the value of CO2 concentration (ppm) is 1589.72 during the morning hour, relative humidity has an average value of 68.11 and the average temperature value that has been recorded is 23.720C. The results obtained from the user's answers to the questionnaires that have been distributed that revolve around ergonomic risk factors that affect health symptoms as well as comfort and user satisfaction are in line with the reading results recorded from the measurement tool that records the value of vibration, noise and ventilation risk. This study model can be used to develop and build a public transport system that considers ergonomic risk factors to enable this vehicle to provide a healthy train cabin for the passengers. By taking separate data by gender, it can also be done by comparing other railway companies to enable validity to be done better by comparing the results obtained from two different railway transport companies.
