Abstract

As technology continues to advance and Indonesia's population experiences rapid growth, transportation is also progressing. The train is a mode of transportation designed to carry passengers and goods, whether in small or large quantities, over long distances. Trains are one efficient modes of land transportation. This research located along Tarahan Bakauheni route, with the shortest straight distance spanning 50 km. The data used for the design of this railway track includes Passenger Data from Bakauheni Port, Coal Cargo Data, Topography Data, and other supporting data. The planning phase is carried out using regulations such as Ministerial Regulation No. 60 of 2012, PD 10, and other relevant rules. In the railway design, used is Class I with a track gauge of 1067 mm. The Horizontal Alignment planning for the route involves 42 curves with the SCS type, where each curve has a radius of 850m, a track elevation of 79.023 mm, and a transition curve length of 94.828 m. Class I railway has a maximum ruling gradient of 10‰ and includes 18 vertical curves with a radius of 8000m. The structure of the railway uses R60 type rails with concrete sleepers and employs double elastic fasteners of the Pandrol Fastclip type.

Abstract

Jaringan jalan yang baik merupakan faktor utama dalam mendukung mobilitas dan pertumbuhan ekonomi suatu daerah. Kabupaten Ogan Ilir menghadapi tantangan dalam menentukan prioritas perbaikan jalan. Dengan nilai kemantapan jalan dibawah 60% akibat keterbatasan anggaran dan sumber daya menyebabkan tidak memenuhinya standar pelayanan minimum jalan kabupaten. Penelitian ini bertujuan untuk menganalisis prioritas penanganan perbaikan jalan menggunakan Sistem Informasi Geografis (GIS) dan metode Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Beberapa kriteria yang digunakan dalam analisis ini meliputi tingkat kemantapan jalan Kabupaten Ogan Ilir, tingkat mobilitas jalan, tingkat aksesibilitas jalan, dan kelengkapan fungsi jalan. Hasil analisis menunjukkan bahwa kombinasi GIS dan TOPSIS dapat memberikan pemetaan prioritas perbaikan jalan secara objektif berdasarkan tingkat urgensi. Visualisasi dalam GIS memungkinkan pemangku kebijakan untuk mengambil keputusan yang lebih efektif dalam alokasi anggaran dan perencanaan infrastruktur. Dengan pendekatan ini, perbaikan jalan dapat dilakukan secara lebih strategis guna meningkatkan aksesibilitas dan kesejahteraan masyarakat di Kabupaten Ogan Ilir.

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

The production volume target from 24.8 million tons in 2020 to 29.5 million tons in 2021 underlies the optimization of transportation availability in distributing coal mining products carried out by PT Bukit Asam Persero in achieving the growing target until 2023. In 2021, the Company will increase investment in developing business diversification, downstream coal. The railway network in Sumatra has a strategic role in serving the distribution of coal transportation. The railway line, which is directly connected to the location of the mining plant to port access and the availability of locomotive facilities and wagons that are very adequate, is an attractive option for mining companies and freight forwarders to establish coal transportation cooperation by rail. To meet the Babaranjang train tonnage target of 52 tons / year in accordance with the target of PT Bukit Asam (Persero), the Loop rail line design at TLS T4 PT Bukit Asam Muara Enim used the most effective classification. From the calculation results, 55 train trips are required per day to transport the production target of 57 tons / year in 2023. It is necessary to pay attention to the adequacy of the rail track from the TLS loop to Tanjung Enim Baru here it is necessary to conduct a study regarding the traffic from TLS to Tanjung Enim Baru because the number of trains set per day is 55 sets.
