Abstract

Line 5 of the Bekasi Station Emplacement is a new line from the addition of a Double Double Track at the Bekasi Station Emplacement which will later be used as a direct train line with a maximum speed of 100 km/hour. The existence of 10 fixed curves and 2 temporary arches on line 5 needs to be evaluated for feasibility so that it can be crossed by trains at high speed. The evaluation is carried out in the form of an evaluation of the horizontal curve geometry which includes the evaluation of the minimum radius, rail elevation, the value of the bow arrow, and the allowable operating speed of the train. In addition, periodic maintenance plans can also be determined based on the analysis carried out on the horizontal bending radius. This evaluation is based on the Minister of Transportation Regulation No. 60 of 2012. From the evaluation for curves crossed by a train with a speed of 100 km/hour, all curves still meet the minimum radius requirements. While the 2 temporary arches are used to limit the speed of the train during the construction of the line, which will later be dismantled. In the evaluation of rail elevation all arches are eligible for outer rail elevation. Furthermore, an analysis of the actual value of bow arrows is also carried out in the field. From the analysis carried out, the arc needs to be adjusted to the specified arrow value.

Abstract

Speed is one of the factors supporting passenger comfort in rail transportation. The problem that occurs when the train is on a longspan is that the speed does not affect passenger comfort. The solution to this problem is that the train must go through a simulation process with the aim of knowing the efficient speed received by prioritizing comfort when passing a longspan. The simulation was carried out using the Longitudinal Train Dynamic (LTD) method by comparing the ride index value of the simulation results with the ride index value set in KP 765 of 2017 concerning the Design and Specifications of the Jabodebek LRT which refers to ISO 2631 Jabodebek. Based on the standards determined, the researchers carried out simulations with variations in speed to determine the effect of speed variations on the travel index value, so that the efficient speed at the longest long span of passengers was known. The simulated speeds are 10 kmh, 20 kmh, 30 kmh, 40 kmh, 50 kmh, and 60 kmh. The data from this study is the ride index value of the simulated speed variation. The results of this study are the ride index value at a speed of 10 kmh is 1.4747427, 20 kmh is 1.6533716, 30 kmh is 1.8409451, 40 kmh is 2.2335365, 50 kmh is 2.4009598, and 60 kmh is 2.6713053. And the optimal speed of the Jabodebek LRT is in the range of 30-40 kmh.

Abstract

Noise is an annoying sound when listened to for a long time. The standard for noise level in housing is based on KepMenLH No. 48 of 1996 worth 55 dB(A). Double track rails lead to increased rail operations and noise in the surrounding environment. This research was conducted to analyze the environmental noise level due to the train crossing the double track rail at Graha Kirana Winongo Housing, Madiun City by using a Sound Level Meter (SLM) device. Measurements were made at two points, namely at a distance of 7.5 meters and 21 meters. The results of the study the average value of environmental noise due to trains at a distance of 7.5 meters is 80 dB(A) and a distance of 21 meters is 75 dB(A). This value exceeds the standard noise level of 55 dB(A). Researchers provide mitigation in the form of suggestions for housing residents to build noise barriers or plant trees with dense leaves, and if residents are going to build new housing, it is recommended to be at a distance of 75 to 80 meters from the train tracks because the noise value at that distance is approximately 55 dB (A).

Abstract

Train signaling is used of a certain shape, color, or light to give the driver a message that will ensure a safe train journey. Upgrading the signaling infrastructure at stations all over Java and Sumatra. One of these entails updating the station's electrical signaling, which was previously constructed in 1986. Equipment spare components, which are challenging and frequently encounter problems that impair the system's dependability, are the primary factor being refreshed. This electrical signaling makes use of the SILSafe4000 system, which was created by PT LEN's youth. In this study, the researcher examined the cross-capacity calculations, equipment standardization, and questionnaires given to PPKA officers to investigate the SILSafe4000 electrical signaling reliability system at the lempuyangan station by making use of cross-capacity estimates, equipment standardization, and questions given to PPKA personnel about how challenging it is to operate the Lempuyangan HMI station. The necessary data was gathered by the researcher in advance of the study. Based on standardization of the equipment, BSG9 motor voltage standard and signal 110VAC±10%, detection voltage (inverse) 24VDC±10%, or range (21.6-26.4V DC), rated current < 10A, ground 5Ω, R≤50Ω, and insulation.
