Abstract

A very important element of railway is the rail bearing, different types of rail bearings that we know in Indonesia are wooden rail bearings, concrete rail bearings. In this study, the stress behavior that occurs in the two types of railway bearings due to the load and the occurring temperature effect is to be checked. It was found that the stress occurring in bearings with different materials, namely concrete and wood, when the The nominal stress can be seen on the concrete bearing is 11.87 N/mm2, on the wooden material the bearing load is 10.41 N/mm2. As for the temperature effect, it looks similar to the temperature of 80 °C for each material, but it can be seen that the temperature effect spreads from the surface due to the friction between the railroad tracks and the railroad wheels.

Abstract

Ministerial Regulation number 175 of 2015 about Technical Specification Normal Speed Trains with Self-Propelling, the hardness rate of the train wheels must be lower than the hardness of the rail road. Trains operating at speeds of are considered as normal speed trains. Based on field observations, generally the flange is wear faster. In cases where flanges are wear out, the wheel’s flange must be to restored to its proper condition as long as the wheel diameter is still possible. This research was carried out by processing data using the Trend Linear and using the excel to get the results of a comparison of which wheels are faster to wear out on flange for each wheel in one train arrangement and which route causes wear out faster. Based on the data obtained, the Yogyakarta – Kutoarjo route traversed by An Electric-Diesel Locomotive Prambanan Express (Prameks) causes wear on flange than the Yogyakarta – Yogyakarta International Airport (YIA) route traversed by An Electric-Diesel Locomotive YIA and on the Solo – Wonogiri route traversed by An Electric-Diesel Locomotive Batara Kresna due to the total length of the mileage. and the longest total arc length of the two compared Lines. Meanwhile, the Solo – Wonogiri route traversed by An Electric-Diesel Locomotive Batara Kresna is ranked second in the cause of flange due to the smallest bend radius of the two compared lines. As well as the ranking of the last traffic that causes flange is the Yogyakarta - YIA.

Abstract

Light Rail Transit (LRT Jabodebek) is a light rail train that serves 2 operational crossings, namely cibubur Line and Bekasi Line. The problem that occurs in Jabodebek LRT is abnormal wheel flange wear. This problem will have an impact on the wheel life to be shorter. Therefore, this study aims to analyze the cross that has the most influence on the wear rate of the Jabodebek LRT wheel flange and find out when turning will be carried out. The flange measurement data obtained from daily and monthly maintenance data will be analyzed using the simple linear regression method. The value of flange wear caused by Lintas Harjamukti-Dukuh Atas of 0.00285 mm in one trip is greater than Lintas Jatimulya-Dukuh Atas of 0.001295 mm. While trainset 1 will be turned after traveling 117,962 km or 3944 trips, trainset 2 will be turned after traveling 74,061 or 2424 trips, trainset 13 will be turned after traveling 237,295 km or 7908 trips, trainset 18 will be turned after traveling 85,911 km or 2707 trips. Therefore, the Harjamukti-Dukuh Atas section has a greater influence on the wear that occurs compared to the Jatimulya-Dukuh Atas section.

Abstract

Early childhood education is the main education towards higher education. Early childhood education must pay attention to the maturity of children in all aspects of life. Knowledge and understanding of something can be instilled into early childhood by various methods. In instilling understanding in children through direct recognition so that children will be stimulated through hearing (auditory) and sight (visual). The introduction of means of transportation is usually an attraction in itself for early childhood. Transportation tools become easy to understand because they are often seen even using these means of transportation. The introduction of means of transportation is carried out through auditory, visual and psychomotor. Improved auditory and visual abilities are obtained by the method of telling stories about trains. Videos are also shown to facilitate the child's understanding. Increasing children's knowledge and psychomotor using field trips directly by train to gain experience

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

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

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.
