Abstract

Trains operate supported by many factors, one of which is signaling and telecommunications equipment. This equipment must get a continuous supply of electricity, so that train operations are safe and smooth. One way to protect the power supply is by installing a battery uninterrupted power supply (UPS), as a source of electrical energy storage as a backup. To keep the battery in optimal condition, 1 month, 3 months and 12 months preventive maintenance is carried out. Treatment 12 months, tested with the method coulomb counting with discharge against the battery up to 80% total wasted capacity, to get the value state of health battery. There are 54 batteries valve-regulated lead acid (VRLA) with a voltage of 2 V and a nominal capacity of 200 Ah, which is connected in series with the voltage cut off 1.85 V. The results of preventive maintenance are seen by testing discharge battery at station A, namely the SoH condition where all the batteries are above the value of 80%, while at station B there are 5 batteries with SoH values ​​of 78%, 80%, 58%, 74%, and 72%, so the batteries must be replaced at fifth batteries with SoH rating of 80% and below.

Abstract

KRL Commuter Line and MRT Jakarta, serving urban population mobility with high transport capacity. The development of urban rail signaling, making the choice of signaling system application to headway be competitive. However, it is necessary to choose the right one, so this research is carried out, with the aim of knowing the effect of the signaling system on headway urban railways, by comparing conventional and CBTC signaling systems. This research method is quantitative and qualitative, using primary data from observation at MRT Jakarta, Gapeka KRLCommuter Line and Time Table MRT Jakarta, interviews with experts and passenger through techniques purposive sampling and based analysis coding. The results of research that CBTC uses moving block, make headway more stable. Headway Jakarta MRT 3 minutes, with 99.98% time liness and better than KRL Commuter Line. Factor affecting headway urban trains, namely crossing gates, number of facilities, length of traffic, number of stopping stations, dwelling time, signaling systems, and personnel.
