Abstract
Perbaikan dan penggantian komponen mesin pesawat terbang penting dan harus dilakukan karena setiap komponen memiliki batas usia pakai tertentu. Perbaikan pada komponen yang mengalami kerusakan tidak selamanya efisien. Jika komponen yang rusak telah mengalami beberapa kali perbaikan, maka keandalan dari komponen ini akan semakin menurun dan laju kerusakannya akan semakin meningkat seiring dengan bertambahnya waktu. Penelitian ini bertujuan untuk menentukan waktu penggantian (replacement) komponen Air Cycle Machine (ACM) pesawat terbang CRJ-1000 yang optimal di PT. Garuda Maintenance Facility (GMF) AeroAsia dengan metode Geometric Process yang menyatakan bahwa setelah komponen diperbaiki maka dianggap memiliki kinerja dan keandalan yang menurun secara linier. Hasil penelitian menunjukkan bahwa komponen Air Cycle Machine (ACM) pesawat CRJ-1000 akan diganti setelah terjadi kerusakan yang ke-4 yang dapat meminimumkan biaya penggantian. Estimasi rata-rata biaya penggantian jangka panjang per hari komponen Air Cycle Machine (ACM) pesawat CRJ-1000 yang minimum adalah US$ 6961.

Improvement and replacement in aircraft components are necessary and should be done due to the limited life span of the components. Improvement in damaged components is not always efficient. If the damaged component has undergone several improvements, the reliability of the component would be decreased and the rate of other damages are increasing as time goes by. This study aims to determine the optimal replacement time of Air Cycle Machine (ACM) component of the aircraft CRJ-1000 in PT. Garuda Maintenance Facility (GMF) AeroAsia using Geometric Process method which stated that after the improvement, the reliability of the component would be decreased linearly. The result of the study shows that the Air Cycle Machine component of aircraft CRJ-1000 should be replaced after the 4th damage and it could minimize the cost of replacement. The estimated average cost per day of a long-term replacement of the component starts at US$ 6961.
