Abstract

Program pengabdian masyarakat ini dilakukan oleh dosen Bahasa Inggris Politeknik Perkeretaapian Indonesia kepada petugas PT Kereta Api Indonesia China (PT KCIC). Target dari program ini adalah 23 orang calon petugas pelayanan penumpang karena mereka diharapkan dapat melayani penumpang lokal maupun internasional. Oleh karena itu, mereka harus memiliki kemampuan bahasa asing yang memadai (terutama bahasa Inggris) untuk memberikan pelayanan yang prima. Strategi pengembangan masyarakat digunakan dan metode praktis yang diintegrasikan ke dalam Technical Communication Pedagogical Model (TCPM) dalam konteks perkeretaapian diterapkan. Hasil penelitian menunjukkan bahwa para peserta menunjukkan kinerja yang lebih baik dalam mempraktekkan komunikasi dalam bahasa Inggris setelah pelaksanaan pelatihan. Sehingga dapat disimpulkan bahwa model pembelajaran dengan menggunakan pendekatan komunikasi teknis mampu meningkatkan kemampuan berbahasa Inggris petugas pelayanan penumpang dalam konteks Kereta Api Cepat.

Abstract

Lubrication can be defined as the provision of lubricating materials to a machine that aims to prevent direct contact between moving surfaces. Viscosity is a very important property in lubricating oil. Sampling of engine oil was carried out on locomotives CC 206 13 18 and CC 206 13 45 at Depo Lokomotif Sidotopo Daop 8 Surabaya. Testing of engine oil samples was carried out at the ITS Surabaya Laboratory and PT Sucofindo Surabaya based on ASTM D 445-97, ASTM D 95-13, and ASTM D 482 standards. The results of the test will be compared with the locomotive engine oil eligibility limit standard. From the tests carried out, it was found that the oil in CC 206 13 18 produced a kinematic viscosity of 15.86 cSt, water contamination of 0.07%, and dissolved solid pollutants of 0.973%. CC 206 13 45 produces a kinematic viscosity of 15.38 cSt, water contamination of 0.06%, and dissolved solid pollutants of 0.917%. From the tests on the two locomotives, it was found that the kinematic viscosity, water contamination, and dissolved solid pollutants of engine oil CC 206 13 18 and CC 206 13 45 are still within the limits of feasibility. Kinematic viscosity can affect the maximum mileage of the locomotive. The result on CC 206 13 18 is 186,962 km and on CC 206 13 45 is 194,352 km. So the oil can still be used beyond the manufacturer's specified distance limit.

Abstract

The study aimed to comprehensively analyze the impact of curves on railway tracks on the wear level of train wheel flanges. The case study focused on the Yogyakarta-Kutoarjo line, which presented a unique track with several curves. Data collection involved meticulous measurements of wheel flange wear on regularly operating trains along the line, along with a thorough analysis of track geometry, train operating speeds, and wheel materials. This quantitative research employed the linear regression method to analyze the data. The findings revealed a notable correlation between wheel flanges A and B's wear levels and curves on the Yogyakarta-Kutoarjo railway line, with 1.036 mm and 1.495 mm of wear on wheels A and B, respectively. The R2 value falling within the range of 0.7521 to 0.9678 indicated a significant influence on wheel flange wear. The study also identified the furthest curved distances, 102,304.80 km for wheel A and 136,857.00 km for wheel B. This research is anticipated to make meaningful contributions to the advancement of railway track and wheel maintenance, ultimately enhancing railway systems' safety and operational efficiency.

Abstract

The flange is an essential part of the wheel that serves to guide the wheel as it passes through curves. If worn, the flange can cause derailments and reduce the wheel’s service life. In LRT Jabodebek, flange wear is relatively high, requiring re-profiling (turning). This study aims to identify the effects of flange wear and explore methods to mitigate it. The analysis method uses a fishbone diagram to identify the root causes. The results show that flange wear is caused by the high number of curves with a radius less than 150 meters, which do not fully comply with existing maintenance standards. Reduced surface hardness due to repeated reprofiling and lack of thorough inspection during maintenance also contributes. Efforts to reduce wear include re-evaluating curves with small radii, adjusting rail widening and elevation, using coolant during turning, and conducting more thorough visual and manual inspections. Additionally, applying lubricant to the flange and rail curves can help minimize wear.
