Abstract

PT GMF Aero Asia bergerak dalam sektor Maintenance, Repair, and Overhaul (MRO) pesawat terbang, termasuk pemeliharaan Unit Load Device (ULD) Container & Pallet yang ditangani oleh unit TBR-8. Unit ini memiliki permasalahan dalam proses layanan pemeliharaannya yaitu lamanya kedatangan material ULD, kelelahan fisik teknisi akibat pergerakan bolak balik (working area - toolbox - lemari material) untuk mengambil material atau peralatan, serta perpindahan dokumen preliminary tanpa penambahan informasi signifikan bahkan sering hilang. Permasalahan tersebut sangat berkaitan adanya indikasi potensi waste berupa waiting, motion, dan transportation. Sebagai upaya mengurangi dan mengeliminasi waste yang terjadi pada layanan pemeliharaan ULD oleh GMF, dilakukan perbaikan melalui pendekatan lean service dengan mengintegrasikan beberapa tools yaitu Cross Functional Flowchart, Value Stream Mapping (VSM), Process Activity Mapping, Gemba Shikumi, 5 Why's Analysis, dan Lean Matrix 2. Berdasarkan penggambaran flowchart didapatkan 9 aktivitas besar dalam layanan pemeliharaan ULD dengan keterlibatan beberapa pihak seperti pelanggan, manajer unit, petugas PPC, petugas warehouse, dan teknisi. Hasil pemetaan VSM didapatkan bahwa terdapat indikasi pemborosan melalui cycle time terlama yaitu pada aktivitas perform maintenance repair, receive ULD and check documents, serta request material yang kemudian lebih lanjut ditemukan jenis waste berupa transportation dan delay melalui PAM. Dengan gemba shikumi diperoleh 9 critical waste yaitu menunggu pemenuhan request material, menunggu konfirmasi PPC terakit informasi sheet preliminary inspection, mengambil material, mengambil peralatan, mencari peralatan, mengambil peralatan cleaning, mencari peralatan cleaning, serta menunggu konfirmasi teknisi terkait penyelesaian kerja. Kemudian akar penyebab akan diidentifikasi melalui 5 Why's Analysis, sehingga didapatkan urutan alternatif rekomendasi perbaikan terbaik menggunakan lean matrix 2 yaitu dari rekomendasi tertinggi hingga terendah yaitu perubahan quality form preliminary, penyesuaian tata letak fasilitas, pembuatan panduan pengadaan material, pemberian label nama dan pembatas lemari, serta smart drawer.

PT GMF Aero Asia operates in the aircraft Maintenance, Repair, and Overhaul (MRO) sector, including the maintenance of Container & Pallet Unit Load Devices (ULD), which is handled by the TBR-8 unit. This unit faces several issues in its maintenance service process, namely the long arrival time for ULD materials, the physical fatigue of technicians due to moving back and forth between the barracks (working area - toolbox - material cupboard) to pick up materials or equipment, and the transfer of preliminary documents without adding significant information and often getting lost. These problems are closely related to indications of potential waste in the form of waiting, motion, and transportation. To reduce and eliminate waste in ULD maintenance services by GMF, improvements are made through a lean service approach by integrating several tools including Cross Functional Flowchart, Value Stream Mapping (VSM), Process Activity Mapping, Gemba Shikumi, 5 Why's Analysis, and Lean Matrix 2. The flowchart illustration identifies 9 major activities in ULD maintenance services involving various parties such as customers, unit managers, PPC officers, warehouse staff, and technicians. VSM mapping results indicate waste through the longest cycle times in performing maintenance repair, receiving ULD and checking documents, and requesting materials. Further, waste types such as transportation and delay are identified through PAM. Gemba Shikumi identifies 9 critical wastes including waiting for material requests to be fulfilled, waiting for PPC confirmation related to preliminary inspection sheet information, retrieving materials, retrieving tools, searching for tools, retrieving cleaning tools, searching for cleaning tools, and waiting for technician confirmation on work completion. The root causes are identified through the 5 Why's Analysis, leading to the prioritization of improvement recommendations using Lean Matrix 2. The recommendations from highest to lowest priority are changing the preliminary quality form, adjusting the facility layout, creating material procurement guidelines, labeling and partitioning storage cabinets, and implementing smart drawers.
