Abstract: Transit-oriented development (TOD) is one of the sustainable urban development concepts in tackling congestion, environmental degradation, and energy efficiency. To realise transit-oriented development, the government issued a transit-oriented development policy at every rapid mass transit (MRT) station in DKI Jakarta. The Mass Rapid Transit train (MRT) Jakarta has dimensions of 20 meters long, 2.9 meters wide and 3.9 meters high. Dominated by metallic blue and grey, the train body is made of stainless steel with an empty weight per train reaching 31 to 35 tons. PT MRT Jakarta provides 16 train series (one series consists of six trains) so that the carrying capacity of one series reaches 1,950 people per series. The train’s interior is equipped with air conditioning, two CCTVs, hand straps, priority seats and a particular wheelchair area. Seats are made of fibre reinforced plastic (FRP) which is fire resistant with a width of 43 cm x 42 cm. This study aims to analyse the passenger posture by the Reba method with the results of measurements obtained in section a, namely 6, section b is 5, and the meeting point between parts a and b is 8. That is, the results of the Reba score have a high level of risk with immediate action needed. From the results of calculations, it is found that the sitting position of the MRT passenger is not ergonomic. Therefore, the authors analysed the posture of the passengers of the Jakarta MRT passenger with the Reba method to provide suggestions for improving posture and seats.
