Abstract

Tujuan pengabdian ini untuk memberikan kemudahan kepada tenaga perawat lokomotif di golongan kelistrikan khususnya pada pelepasan inner race bearing pada generator lokomotif. Hal itu dikarenakan Proses pelepasan inner race bearing pada generator lokomotif dengan tenaga manual dapat menyebabkan risiko terhadap keselamatan pekerja maupun pada kecacatan generator tersebut. Metode yang digunakan dalam pengabidan ini berupa perancangan, desain dan manufaktur, serta sosialisasi penggunaan alat dan penyerahan alat kepada Balai Yasa Yogyakarta. Hasil desain dan menufatur alat pelepas inner race bearing pada generator dipraktikan dan diuji di workshop Balai Yasa Yogyakarta. Pengujian ini menggunakan variabel yaitu waktu pelepasan dan efisiensi jumlah tenaga. Pengujian dilakukan sebanyak empat kali dengan jumlah tenaga perawatan yang melakukan perawatan yaitu sejumlah 2 orang dan rata-rata pelepasan adalah 2,8 detik. Alat ini di serahkan kepada Balai Yasa Yogyakarta supaya dapat digunakan untuk memudahkan perawatan lokomotif.

Abstract

The maintenance of air springs on ND-748 and ND 748-T type bogies in Jakarta MRT facilities requires a complex and time-consuming process. This community service research project aims to design, develop, and socialize the use of a crane trolly jig air spring tool to improve the efficiency of the maintenance process. The methodology employed includes data collection, chain block calculations, design using Solidworks 2023, and a manufacturing process encompassing tool and material preparation, material cutting, welding, component assembly, and finishing. Testing results indicate that the developed tool is safe to use and functions properly. This tool can reduce the time required for air spring removal and maintenance from 4-5 minutes to a more efficient duration, while facilitating installation at a rate of 5 minutes per air spring. As part of the community service aspect, this auxiliary tool has been handed over to PT. MRT Jakarta, accompanied by socialization of its usage to facilitate maintenance of their facilities. This research is expected to contribute to improving efficiency and safety in the maintenance of public transportation systems in Jakarta.

Abstract

This study aimed to ensure that plastic deformation does not occur on the structure of bolster bogie 1722 when it accommodates burdens or loads based on previously determined overload limit. The simulation in this study used the finite element method with the help of Ansys Workbench 2020. The standard of testing UIC 515-4 was employed as a reference for the simulation, notably in determining the load case. The result of static simulation on the overload showed that the maximum stress on the vertical load case was 72.764 MPa, and the maximum stress on the transverse and vertical load case (combination) was 109.9 MPa. The result of maximum vertical deflection was obtained from the case of vertical load as 0.553 mm and in the case of transverse and vertical load (combination) as 1.799 mm. The structure of the bolster design is considered safe because the maximum score of stress was under the yield strength score of the used material, namely SS400 as 245 Mpa.

Abstract

This research conducted dynamic simulations using the Universal Mechanism software with variations between back to back widths of 1000 mm and 990 mm, focusing on the relationship between train operating speed, vibration levels, and passenger comfort index during operation on a small curve on the PPI Madiun track with a radius of R42. The issue investigated in this study stems from PM No. 17 of 2011, which sets the standard back-to-back usage at 1000 mm. It is crucial to understand the characteristics of each back to back setting, as the operational track gauge used is 1067 mm. The simulation results indicate that the nadal criterion and ride index are more favorable with the 990 mm back to back setting. At a speed of 25 km/h, the nadal criterion for the 990 mm setting was 0.636, compared to 0.670 for the 1000 mm setting, and the ride index for the 990 mm setting at this speed was 1.315449, compared to 1.288552 for the 1000 mm setting. These results are considered valid as the error value in the data validation calculations was less than 10%, specifically 8.26%.

Abstract

Blends of biodiesel, like B35, are becoming more and more popular as the demand for cleaner energy sources grows. There are a number of difficulties with using biodiesel, particularly with respect to diesel engine fuel filtration systems. The purpose of this study is to determine the fuel filter's level of contamination at particular mileage intervals, assess how well the filter works with biodiesel blends, and calculate the fuel filter's lifespan when using B35 biodiesel. The authors have conducted an experimental study involving a testing apparatus to measure the flow rate at the filter. Real-time data on fuel flow rate and filter cloggi ng rate will be collected and analyzed to determine the impact of filter efficiency on fuel changes. The experimental data will be compared and contrasted to draw meaningful conclusions about the correlation between filter clogging and fuel flow rate. The data shows that the CC201 filter experiences less contamination compared to the CC203 filter. These results suggest that the CC201 maintains better performance at the distances tested. Filter quality was estimated based on the remaining flow rate capacity, showing a direct correlation between mileage and filter deterioration. Firstly, it was found that the level of contamination experienced by the CC201 fuel filter was superior to that of the CC203 filter. Secondly, the relationship between fuel filter life and locomotive mileage is illustrated by a scatter plot graph showing a decreasing trend line. Thirdly, from the use of B35 fuel, the performance of the fuel filter decreased at a percentage of 10% and 13% on each locomotive.

Abstract

This research analyzes the structural strength of the 50-foot Flat Wagon underframe using the finite element method. Modeling was done in Autodesk Inventor and load simulation using ANSYS Workbench with a mesh size of 25 mm. The analysis refers to the UIC 571-4 and EN 12663 standards. The results showed that the maximum stress of 347.56 MPa and maximum deformation of 15.305 mm occurred under combined loading. This value is still below the yield strength of the material (355 MPa), but exceeds 75% of the allowable stress according to KM No. 43 Year 2010 (266.25 MPa). The highest safety factor is 1.82 (compression loading), the lowest is 0.76 (combination loading). This simulation shows the need for design optimization to meet national safety standards..
