Penilaian Indeks Kualitas Jalan Rel (Track Quality Index) berdasarkan Standar Perkeretaapian Indonesia (Studi Kasus : Cirebon-Cikampek)

Abstract

To overcome the movement of railroad traffic growth in Indonesia, especially in the Cirebon-Cikampek Line where the line is one of the busiest routes on Java where it can affect the geometry of the track. In fact, there are a number of geometry parameters that affect the decline in the quality of the railroad tracks, namely profile, alignment, gauge, and cant. The quality of a railroad track is defined as a numerical value representing the relative conditions of the surface geometry of the track. In this case, the track quality assessment indicator is based on the sum of the standard deviations of the four parameters so that the overall segment quality results are called the Track Quality Index (TQI). The use of TQI provides the possibility to assess indicators of railroad performance. This research was conducted to analyze the Track Quality Index based on the Indonesian Railroad Standards. In addition, an analysis using multiple linear regression was performed to find out how much these four parameters affect the TQI value. The TQI results obtained based on the Indonesian Railway Standard of 38,69% are included in the good category while the results of multiple linear regression indicate that all four parameters have a significant effect on the TQI assessment index.
