Abstract

Bogie frame adalah bagian utama bogie yang menerima beban besar selama beroperasi sehingga diperlukan analisis kekuatan struktur untuk memenuhi syarat kelayakan operasional berdasarkan Peraturan Nomor 33 Tahun 2021 tentang Penyelenggaraan Bidang Perkeretaapian dan standar EN 13749. Kelayakan operasional menjadi jaminan keselamatan penumpang, operator, maupun penduduk sekitar perlintasan. Fokus penelitian ini adalah analisis kekuatan desain struktur bogie frame kereta ukur jalur LRT Jabodebek terhadap kelayakan operasional. Tujuan penelitian adalah menganalisis tegangan objek penelitian akibat pembebanan normal service dan memastikan nilai tegangan hasil simulasi memenuhi kriteria keberterimaan standar EN 13749. Solusi penelitian adalah pendekatan endurance limit objek penelitian. Nilai tegangan hasil simulasi dianalisis dengan goodman diagram. Data pendukung penelitian dan parameternya dari hasil survei dan wawancara di PT INKA (Persero). Hasil penelitian adalah lokasi element kritis objek penelitian, nilai tegangan element kritis tiap load case, dan plot nilai tegangan element. Objek penelitian belum memenuhi kriteria keberterimaan EN 13749 berdasarkan analisis dengan pendekatan goodman diagram. Satu element kritis pada bracket gearbox melebihi batas keberterimaan akibat load case longitudinal. Amplitudo tegangan element bernilai 157,09 MPa dari batas keberterimaan 155 MPa. Perubahan ketebalan pipe transform dari 12 mm menjadi 20 mm efektif menurunkan nilai amplitudo tegangan element menjadi 88,41 MPa, sehingga kekuatan desain memenuhi kriteria keberterimaan.

Abstract

Speed is one of the factors supporting passenger comfort in rail transportation. The problem that occurs when the train is on a longspan is that the speed does not affect passenger comfort. The solution to this problem is that the train must go through a simulation process with the aim of knowing the efficient speed received by prioritizing comfort when passing a longspan. The simulation was carried out using the Longitudinal Train Dynamic (LTD) method by comparing the ride index value of the simulation results with the ride index value set in KP 765 of 2017 concerning the Design and Specifications of the Jabodebek LRT which refers to ISO 2631 Jabodebek. Based on the standards determined, the researchers carried out simulations with variations in speed to determine the effect of speed variations on the travel index value, so that the efficient speed at the longest long span of passengers was known. The simulated speeds are 10 kmh, 20 kmh, 30 kmh, 40 kmh, 50 kmh, and 60 kmh. The data from this study is the ride index value of the simulated speed variation. The results of this study are the ride index value at a speed of 10 kmh is 1.4747427, 20 kmh is 1.6533716, 30 kmh is 1.8409451, 40 kmh is 2.2335365, 50 kmh is 2.4009598, and 60 kmh is 2.6713053. And the optimal speed of the Jabodebek LRT is in the range of 30-40 kmh.

Abstract

Noise is an annoying sound when listened to for a long time. The standard for noise level in housing is based on KepMenLH No. 48 of 1996 worth 55 dB(A). Double track rails lead to increased rail operations and noise in the surrounding environment. This research was conducted to analyze the environmental noise level due to the train crossing the double track rail at Graha Kirana Winongo Housing, Madiun City by using a Sound Level Meter (SLM) device. Measurements were made at two points, namely at a distance of 7.5 meters and 21 meters. The results of the study the average value of environmental noise due to trains at a distance of 7.5 meters is 80 dB(A) and a distance of 21 meters is 75 dB(A). This value exceeds the standard noise level of 55 dB(A). Researchers provide mitigation in the form of suggestions for housing residents to build noise barriers or plant trees with dense leaves, and if residents are going to build new housing, it is recommended to be at a distance of 75 to 80 meters from the train tracks because the noise value at that distance is approximately 55 dB (A).

Abstract

The Sembawa-Betung double rail track is one of the planned routes of the Trans Sumatra Railways project in Sumatra Island dedicated to passenger and goods transportation. This study aims to analyze the train operating systems of Sembawa - Betung double rail track, that consist of the effective length and the typical layout of rail track, train traffic management, the potential of train travel routes that can be formed, used and conflicted, and the calculation of routes loading level on the train frequency. Based on the analysis conducted using the Conflict Rate method, it can be summarized that the route utilization along with trains frequency served at Sembawa Station, Pangkalan Balai Station and Suak Tapeh Station almost reaches the maximum level of allowable conflict so it may increase the probability of train accidents if there is an additional number of trains served without the construction of additional rail track at the station. On another side, the route utilization, along with the frequency of the trains served at Betung Station, is still far below the maximum limit of allowable conflict, so that there is a possibility to increase the frequency of the trains without the need for additional rail track at the station.
