Abstract

Abstract The use of composite materials has been developed in the railroad transportation industry sector in Indonesia. For example, PT INKA has used composite materials with fiber glass reinforcement. The purpose of this study is to determine the characteristics of tensile strength and bending strength of the composite material so that it can be proposed to be further developed and utilized by the manufacturing industry, especially the railroad industry. In this study, 4 types of matrix variations were examined, namely epoxy, repoxy, polyester, and bhispenol using fiber glass reinforcement. Tensile strength and bending strength tests were performed in accordance with the ASTM D-638 and the ASTM D-790 standards, respectively. The results of this study indicate that the variation of the matrix is very influential on the tensile strength and bending strength of composite materials. Keywords: composite material, glass fiber, tensile strength, bending strength  Abstrak Penggunaan material komposit mulai banyak dikembangkan di sektor industri trasportasi kereta api di Indone-sia. Sebagai contoh, PT INKA sudah menggunakan material komposit dengan penguat serat gelas. Tujuan penelitian ini adalah untuk mengetahui karakteristik kekuatan tarik dan kekuatan bending material komposit agar dapat diusulkan untuk lebih dikembangkan dan dimanfaatkan oleh industri manufaktur, khususnya industri kereta api. Pada penelitian ini digunakan 4 jenis variasi matriks, yaitu epoxy, repoxy, polyester, dan bhispenol dengan menggunakan penguat serat gelas. Pengujian kekuatan tarik menggunakan standar ASTM D-638 dan pengujian bending menggunakan standar ASTM D-790. Hasil studi ini menunjukkan bahwa variasi matriks sangat berpengaruh pada kekuatan tarik maupun kekuatan bending material komposit. Kata-kata kunci: material komposit, serat gelas, kekuatan tarik, kekuatan bending

Abstract

LRT Jakarta is one of the transportation service providers in the rail sector in the Jakarta area. LRT Jakarta has 8 trainsets of trains. In 1 trainset, the train has 8 passenger doors which have two types, namely type A and B. Vibration on the train causes the door to decrease gradually. Damaging often occurs when the train is operating, such as system errors and system failures. This study has the purpose to know the maintenance actions of the passenger system with Reliability Centered Maintenanc (RCM) and to know the possible causes of failure and the effects of the passenger door system of LVR train. This research uses Reliability Centered Maintenance. where the analysis has been done in the form of analysis of data processing starting from the functional block diagram. the next is the determination of the system and functional failure, by looking for the value of the risk priority number and failure mode and effect analysis. After that, the logic tree analysis prioritizes each mode of damage and performs a review of the functions; the last one provides a proposed maintenance action policy. The results of the research can be carried out actions on the components of the LRV train passenger door system where 7 components can be carried out maintenance actions with condition directed conditions and 1 component is carried out time directed actions. furthermore, the results of this study also explain about the possible failures and consequences caused to each component that has been discussed.

Abstract

One of the facility maintenance performed on the bogie is removing the rubber journal spring. The removal of the rubber journal spring is still done manually, namely slamming it to the floor using a long bolt of about 10 cm which is inserted into the hole in the rubber journal cap to push the rubber so that it can be released from the hat within 8-10 minutes. This research was conducted to innovate tools with the aim of facilitating the maintenance process, shorter time and guaranteed safety in removing the rubber journal spring. The manufacturer of this release tool uses a pneumatic system with the components used in the form of a cylinder with a diameter of 100 mm × 200 mm in length, a 4/2 pust button valve, an air filter, a manometer, and an 8 mm air hose. From the test results, the rubber journal spring removal tool on bogie K5 using a pneumatic system requires 1.2 minutes with a pressure of 5 bar to release 1 rubber journal spring. This tool has dimensions weighing 40 kg, length 50 cm, width 30 cm, height 90 cm. Keyword: rubber journal spring, bogie, pneumatic

Abstract

Level crossings are always a complex problem because accidents often occur at level crossings, whether at official or unofficial level crossings, guarded or unguarded. This community service aims to provide education, insight, and knowledge about railroad crossings to the people of West Sumatra. The method used in this activity is Community Based Research (CBR) by applying approach. This community service was carried out through face-to-face learning and practice in the field, which was attended by 26 people. The result of this service is that the people of West Sumatra increasingly understand and realize the importance of safety at level crossings. This training is very useful because initially the training participants did not know about safety at level crossings, but after attending the training the participants gained very significant knowledge and experience, including being able to know several things about level crossings, starting from regulations, rules and regulations at level crossings and level crossing managers. In this way, the people of West Sumatra, especially training participants, know safety at railway level crossings and understand how to handle emergency conditions at railway level crossings.
