Abstract

Perusahaan Maintenance, Repair, and Overhaul (MRO) pesawat terbang sangat bergantung pada ketepatan ketersediaan material untuk mendukung kelancaran proses perawatan pesawat. Salah satu proses yang memiliki peran penting adalah pengadaan barang sekali pakai, yaitu barang yang digunakan untuk kebutuhan operasional perawatan dan memiliki frekuensi pembelian tinggi. Pada PT XYZ, proses ini masih menghadapi permasalahan berupa waktu proses yang panjang, variasi alur proses, serta kendala pada titik penerimaan barang atau Goods Receipt (GR) yang memperlambat pengadaan. Penelitian ini bertujuan untuk mengidentifikasi bottleneck, menganalisis akar penyebab, serta menyusun usulan rancang ulang proses bisnis untuk mengurangi waktu proses. Penelitian menggunakan kerangka kerja siklus hidup Business Process Management (BPM) yang dibatasi pada tahap penemuan, analisis, dan rancang ulang proses. Analisis data pendukung dilakukan menggunakan directly follow graph pada process mining dengan perangkat lunak Apromore, sedangkan analisis kualitatif menggunakan issue register, diagram Ishikawa, dan why-why diagram. Usulan perbaikan disusun menggunakan metode Heuristic Process Redesign dan dievaluasi melalui simulasi menggunakan Bizagi Modeler. Hasil penelitian menunjukkan bahwa aktivitas pada penerimaan barang datang (goods receipt) menjadi bottleneck utama, yang dipengaruhi oleh perbedaan informasi, kebutuhan validasi spesifikasi material, serta panjangnya rantai koordinasi pada jalur exception. Usulan rancang ulang diterapkan melalui heuristik resequencing, parallelism, case type differentiation, dan numerical involvement. Hasil simulasi menunjukkan penurunan rata-rata waktu siklus dari 31,13 hari menjadi 29,19 hari atau sebesar 6,24%, dan terbukti signifikan secara statistik melalui pengujian confidence interval pada tingkat kepercayaan 95%.

Aircraft Maintenance, Repair, and Overhaul (MRO) companies are highly dependent on the accuracy of material availability to support smooth aircraft maintenance operations. One of the critical processes is the procurement of expendable goods, which are items used for operational maintenance needs with a high purchase frequency. At PT XYZ, this process still faces challenges in the form of long cycle times, process flow variations, and quality issues at the goods receiving point or Goods Receipt (GR) that slow down procurement. This study aims to identify bottleneck activities, analyze root causes, and propose business process redesign to reduce process cycle time. The study applies the Business Process Management (BPM) lifecycle framework, limited to the process discovery, analysis, and redesign stages. Supporting data analysis was conducted using a directly-follows graph in process mining through Apromore, while qualitative analysis employed an issue register, Ishikawa diagram, and why-why diagram. Improvement proposals were developed using the Heuristic Process Redesign method and evaluated through simulation using Bizagi Modeler. The results indicate that the goods receiving activity (Goods Receipt) is the main bottleneck in the expendable procurement process, influenced by information discrepancies, the need for material specification validation, and lengthy coordination chains in the exception path. The process redesign proposals were implemented through the application of resequencing, parallelism, case type differentiation, and numerical involvement heuristics. Simulation results show a reduction in average cycle time from 31.13 days to 29.19 days, or by 6.24%, which was proven statistically significant through confidence interval testing at a 95% confidence level.
