Abstract

In the topology of the DC traction substation there is a rectifier component which generally uses a 12 pulse rectifier type and the load is in the form of a trainset with a component in the form of a converter used for variable speed drives (VSD). The operation of the rectifier and the VSD converter load causes harmonics to appear on the AC input side, so anticipation needs to be done. Therefore, it is necessary to conduct an assessment related to DC traction substations to obtain good electrical power quality. The purpose of this study was to determine the electric power quality parameters of DC railway traction using a 12 pulse rectifier and a VSD converter load. This research was conducted by simulating a DC railway traction model with a 12 pulse rectifier and knowing the comparison of the system power quality between the VSD converter load and the resistive load as the basic reference for the traction substation work system of this model. System modeling is done using PSIM software. The results of the simulation are the parameters of the stability of the voltage, current, and system harmonics.

Abstract

Efficiency, comfort, speed and timeliness are the main factors humans need in mobilisation and transportation. In providing a theoretical basis and technical reference for the quality improvement of high-speed railways in Indonesia, this study comprehensively discusses the theory of geometrical design of high-speed railway tracks and the calculation of excavation and embankment volumes. By using Minister of Transportation regulations Number 7 of 2022 and TB 10621-2014, which contains technical planning for high-speed railway tracks, an alternative route is planned across Bandung to Cirebon Phase I (Rancaekek-Cimalaka) with an operating speed of 350 km/hour, there are 5 horizontal curves and 16 vertical curves calculated using TB 10621-2014 and AutoCAD Civil 3D software. The results obtained from this study are alternative planning of the high-speed railway route along 33,850 meters from Bandung to Cirebon Phase I (Rancaekek- Cimalaka).

Abstract

Corrosion is one of the main problems that can reduce the quality and service life of steel materials in the railway industry, especially on train roofs made of SS400 mild steel. This study aims to examine the effectiveness of adding natural inhibitors from corn cob ash to epoxy primer paint in inhibiting the rate of corrosion and increasing the adhesive strength of the paint. The inhibitor was made through a process of extracting silica from corn cob ash and mixing it into the primer paint at various concentrations. Fourier Transform Infra Red (FTIR) testing was used to identify the silica content in the inhibitor, while testing was carried out on the adhesive strength using an adhesion tester and the corrosion rate using the weight loss test method in HNO₃ solution. The results showed that the addition of corn cob ash inhibitor formed a protective layer on the metal surface, improved paint adhesion, and significantly reduced the corrosion rate. This study demonstrates that the use of agricultural waste such as corn cobs as a natural inhibitor is an innovative, economical, and environmentally friendly solution for controlling corrosion in steel materials in the railway industry.
