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

ABSTRAKMenyeimbangkan objek dinamis yang tidak stabil adalah salah satu masalah yang paling relevan dalam pembangunan sistem kendali otomatis. Metode ini dapat menghasilkan penelitian tentang efek dari suatu sistem kendali otomatis, atau melakukan pengaturan kendali pada suatu plant. Pada penelitian ini, akan dijelaskan bagaimana merancang sebuah ball balancing table (BBT) dan mengimplementasikan sistem kontrol otomasi ke dalamnya dengan menggunakan metode Fuzzy Logic dan PID Controller. Pada penelitian ini didapatkan kesimpulan bahwa pemasangan kendali Fuzzy Logic dan PID Controller memiliki efektifitas paling bagus dibandingkan dengan kendali close-loop ataupun kendali Fuzzy Logic dan PID Controller yang tidak dipasangkan bersamaan. Penggunaan metode Fuzzy Logic dan PID Controller yang menggunakan parameter trial and error dimana memasukkan nilai tuning manual yang dipasangkan pada ball balancing table dan NI MyRIO yang dirancang menghasilkan lama waktu menuju steady state paling singkat yaitu selama 8,7 detik, overshoot paling rendah, dan error yang hanya sebesar 0,4 terhadap nilai koordinat sumbu X dan sumbu Y.Kata kunci: Ball Balancing Table, Fuzzy Logic, Kontrol PID, NI myRIO ABSTRACTBalancing unstable dynamic objects is one of the most relevant problems in the construction of automated control systems. This methode can provide research on the effects of an automatic control system, or carry out a control arrangement on a plant. In this study, will be explained how to design a ball balancing table (BBT) and implement an automation control system into it using Fuzzy Logic and PID Controls methods. And from this research it is concluded that the installation of Fuzzy Logic and PID Controller control has the best effectiveness compared to close-loop control or Fuzzy Logic and PID Controller that are not installed together. The application of the Fuzzy Logic Controller and PID method paired on the ball balancing table and NI MyRio that was designed resulted in the shortest steady state time of 8.7 seconds, the lowest overshoot, and an error of only 0.4 on the X-axis and Y-axis coordinate values.Keywords: Ball Balancing Table, Fuzzy Logic, PID Controller, NI myRIO
