Abstract

Vehicle Maintenance Bridge Inspection (VMBI) yang dikembangkan oleh PT INKA dirancang untuk mendukung operasional LRT Jabodebek, khususnya untuk pemeliharaan struktur bawah lintasan (shortspan). Konsep reliability design menjadi landasan utama dalam penelitian ini, dan keputusan untuk memfokuskan pada aspek keandalan menjadi krusial mengingat VMBI dalam tahap pengembangan. Pertama, functional breakdown digunakan untuk mengidentifikasi sistem, subsistem, dan komponen yang membentuk VMBI. Selanjutnya, reliability block diagram (RBD) disusun untuk menggambarkan konfigurasi antar blok dalam VMBI, juga mengukur keandalan VMBI dan masing-masing sistem penyusunnya. Selanjutnya, failure mode and effect analysis (FMEA) digunakan untuk mengidentifikasi mode kegagalan, dan efeknya pada setiap komponen dari sistem bogie. Dari analisis FMEA dan failure rate, dilakukan penyusunan strategi perawatan untuk setiap komponen dari sistem bogie. Hasil penelitian menunjukkan bahwa VMBI terdiri dari sebelas sistem saling berkaitan. Reliability setiap sistem sangat tinggi dalam operasional selama 1 jam, dengan konfigurasi RBD paralel pada beberapa sistem yang memastikan adanya redundansi. Reliability VMBI mencapai 0,99930936 dengan failure rate sebesar 6,91E-04. Prediksi keandalan menunjukkan penurunan seiring bertambahnya waktu operasional, dengan reliability mencapai 0,806 setelah 1 tahun atau 312 jam. Analisis FMEA mengidentifikasi potensi kegagalan pada beberapa komponen sistem bogie. Strategi perawatan yang diusulkan untuk sistem bogie mencakup pemeliharaan preventif dan korektif untuk meminimalkan risiko kegagalan dan meningkatkan keselamatan operasional VMBI. Penelitian ini diharapkan dapat berkontribusi pada pengembangan VMBI, memastikan kendaraan dapat beroperasi secara efektif, dan memberikan manfaat optimal untuk keberlanjutan infrastruktur LRT Jabodebek.

============================================================

The Vehicle Maintenance Bridge Inspection (VMBI) developed by PT INKA is designed to support Jabodebek LRT operations, especially for maintenance of the shortspan lower structure. The concept of reliability design is the main fondation in this research, and the decision to focus on reliability aspects is crucial, given that VMBI is in the development stage. First, a functional breakdown was used to identify the systems, subsystems and components that make up the VMBI. Next, a reliability block diagram (RBD) was developed to describe the configuration between blocks in the VMBI, as well as to measure the reliability of the VMBI and each of its constituent systems. Furthermore, failure mode and effect analysis (FMEA) was used to identify failure modes, and their effects on each component of the bogie system. From the FMEA and failure rate analysis, maintenance strategies were developed for each component of the bogie system. The results show that VMBI consists of eleven interrelated systems. Reliability of each system is very high in a 1-hour operation, with parallel RBD configurations on some systems ensuring redundancy. Reliability of VMBI reached 0.99930936 with a failure rate of 6.91E-04. Reliability predictions show a decrease as operational time increases, with reliability reaching 0.806 after 1 year or 312 hours. FMEA analysis identified potential failures in several bogie system components. The proposed maintenance strategy for the bogie system includes preventive and corrective maintenance to minimize the risk of failure and improve the operational safety of the VMBI. This research is expected to contribute to the development of VMBI, ensure the vehicle can operate effectively, and provide optimal benefits for the sustainability of Jabodebek LRT infrastructure.
