Abstract

The maintenance process for the excavator cx 210B carried out by the Bekasi City Environmental Service is still implementing a breakdown maintenance system, which means that the unit will be repaired when it has experienced a failure in the system. To improve the performance of the excavator cx 210B to be effective, identification of the factors that cause damage to the undercarrige and hydraulic units on the CX210B Excavator is carried out. Using the Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) approaches. Based on the Pareto diagram, it is known that there are 2 types of damage, namely the travel motor hose with a weight of 29% and a track adjuster with a weight of 22%. From the results of the analysis that has been carried out using the FTA (Fault Tree Analiysis), it can be seen that 2 main factors cause Hydraulic system damage and undercarriage system that affects the performance of the Excavator CX 210B unit. These factors are as follows: Man Factors and Mechine Factors (Heavy Equipment). From the data from the FMEA (Failure Mode and Effect Analysis) analysis, the largest RPN (Risk Priority Number) value for the Track Adjuster was obtained, namely the accumulation of garbage on the undercarriage with an RPN (Risk Priority Number) value of 280 and an RPN (Risk Priority Number) value for Hose montor travel. the largest, namely No routine checks with an RPN (Risk Priority Number) value of 224. Keywords : FTA (Fault Tree Analiysis), FMEA (Failure Mode and Effect Analysis), maintenance, Diagram pareto Proses pemeliharaan Excavator cx 210B yang dilakukan oleh Dinas Lingkungan Hidup Kota bekasi masih menerapkan sistem perawatan breakdown maintenance yang berarti unit akan dilakukan perbaikan ketika sudah mengalami kegagalan dalam sistem. Untuk meningkatkan performace kinerja Excavator cx 210B agar efektif, dilakukannya identifikasi factor-faktor penyebab terjadinya kerusakan unit pada undercarrige dan hydraulic pada Excavator CX210B. Menggunakan pendekatan Fault Tree Analysis (FTA) dan Failure Mode and Effect Analysis(FMEA). Berdasarkan diagram pareto diketahui terdapat 2 jenis kerusakan paling dominan yaitu Hose motor travel dengan bobot sebesar 29% dan Track adjuster dengan bobot sebesar 22%.Dari hasil analisa yang telah dilakukan dengan menggunakan FTA (Fault Tree Analiysis) tersebut, dapat diketahui 2 faktor utama penyebab kerusakan sistem Hydraulic dan sistem undercarriage yang mempengaruhi kinerja unit Excavator CX 210B. Faktor-faktor tersebut adalah sebagai berikut: Faktor Man dan Faktor Mechine (Alat Berat) . Dari data hasil analisa FMEA (Failure Mode and Effect Analysis) tersebut didapatkan nilai RPN (Risk Priority Number) Track Adjuster terbesar yaitu Tertumpuknya sampah pada undercarriage dengan nilai RPN (Risk Priority Number) sebesar 280 dan nilai RPN (Risk Priority Number) Hose montor travel terbesar yaitu Tidak ada pengecekan secara rutin dengan nilai RPN (Risk Priority Number) sebesar 224. Kata kunci : FTA (Fault Tree Analiysis), FMEA (Failure Mode and Effect Analysis), maintenance, Diagram pareto
