Kajian Evaluasi Perlintasan Sebidang di Jalur Perlintasan Langsung (JPL) di Kota Semarang

Abstract

As a mass transportation system infrastructure, level crossings impact road users, including skidding, road
damage, and accidents. Based on data from KAI DAOP 4 Semarang, there were 12 accidents at level crossings
in 2023, while in 2024, the number increased to 26, indicating a rise in accident rates. One accident that went
viral on social media occurred in Semarang in 2023, involving a low-bed trailer that got stuck at a level
crossing. The objective of this study is to analyze and evaluate level crossings, assess their compliance with
regulations, and provide recommendations for improvements. This research employs the triangulation method,
utilizing data obtained from geometric surveys and an inventory of crossing equipment. The study focuses on
level-crossing locations JPL 6 Madukoro and JPL 5 Kaligawe in Semarang City. The findings indicate that the
existing conditions do not fully comply with regulatory requirements in terms of facilities and geometric
specifications. Specifically, the Madukoro crossing is constructed at a higher elevation than the surrounding
topography, creating a hump with a height of 86 cm above the road surface and a grade of 12.8%. This
condition increases the risk of long vehicles, such as low-bed trailers, getting stuck, potentially leading to
severe accidents. Therefore, it is recommended that regulations concerning level crossings be reviewed and
revised.
