Abstract

Rail joints are critical points in railway track infrastructure that affect passenger train ride comfort and safety. This study analyzes their impact along the Tanjung Karang – Rejosari line through Track Quality Index (TQI) and International Roughness Index (IRI Roadbump) measurements, passenger perception surveys using the Analytic Hierarchy Process (AHP), and failure risk evaluation using Failure Mode, Effects, and Criticality Analysis (FMECA) with Weighted Risk Priority Number (WRPN). Results indicate that joints with high TQI and IRI values produce significant impacts, reducing comfort. AHP identified impacts as the dominant factor, while FMECA found the highest RPN in thermite welded joints with the failure mode of “joint corrosion.” The study recommends replacing thermite welding with flash butt welding and converting mechanical joints to permanent welded joints to improve track geometry, reduce failure risk, and enhance comfort and safety.

Abstract

This study applies the Failure Mode and Effect Analysis (FMEA) method, supported by expert opinion, to identify and prioritize damage risks in railway track superstructure components consisting of rails, sleepers, and fastening systems. The case study was conducted on the Divre IV Tanjung Karang railway section at KM 16+00-KM 20+00 using a descriptive quantitative approach. The analysis translates field observations and expert judgments into Severity, Occurrence, and Detection scores to calculate the Risk Priority Number (RPN). The results show that horizontal rail wear, rail-head defects, and cracks at welded joints are the most critical failure modes in rail components; broken sleepers are the main risk in sleeper components; and missing/vandalized fastenings and broken fastenings are critical risks in fastening components. Failure modes were categorized into high risk (RPN > 150), moderate risk (RPN 121-150), and low risk (RPN <= 120). The recommended mitigation emphasizes integrated preventive and corrective maintenance through routine inspection, condition monitoring, control of track geometry and loading, and timely repair or replacement of critical components to improve track infrastructure reliability and railway safety.

Abstract

Prodi Teknik Perkeretaapian ITERA bertujuan mencetak insan perkeretaapian yang profesional dan beretika dengan fokus pada peningkatan kualitas keilmuan serta pengembangan sumber daya manusia dan teknologi perkeretaapian unggul di tingkat regional, nasional, dan internasional. Salah satu syarat kelulusan adalah kerja praktik di instansi perusahaan bidang perkeretaapian. PT. Kereta Api Indonesia (Persero) menjadi tempat kerja praktik bagi mahasiswa Teknik Perkeretaapian ITERA di Unit Infrastructure Assets (TTA). Kerja praktik ini bertujuan mengembangkan keterampilan, pengalaman lapangan, dan memahami budaya organisasi serta keterampilan interpersonal, serta menerapkan ilmu yang dipelajari saat kuliah ke dalam dunia industri perkeretaapian. Tujuan khusus kerja praktik di Unit Infrastructure Assets (TTA) divisi Track Assets and Geometry (TTAT) adalah mengetahui tugas rutin, program pengukuran geometri jalan rel, pengukuran kondisi jalan rel, dan ilmu perkeretaapian terutama di bidang Track Assets and Geometry. Penulis belajar menerapkan teknologi terbaru untuk pengukuran kondisi track, mengoptimalkan kinerja jalur, dan memberikan layanan yang lebih andal dan aman bagi penumpang dan kargo.
