Abstract
The aviation industry, especially air transportation, is said to be the safest transportation. To support flight safety, every airline must pay attention to airworthiness. In this case, periodic maintenance of the aircraft is required. PT GMF AeroAsia Tbk., is one of the largest companies engaged in maintenance, repair and overhaul (MRO) services in Indonesia. However, it is undeniable that in the maintenance process, especially the narrow body base maintenance service, there are costs of poor quality (COPQ) incidents. In 2020 the narrow body base maintenance department experienced 14 COPQ incidents in the aircraft maintenance process and 2229,953 expired consumable Materials and chemicals. With the occurrence of COPQ, this research to determine the highest COPQ and the causes of COPQ, as well as to provide recommendations for improvement using the DMAIC method (Define, Measure, Analyze, Control). Based on the results of calculations using the Pareto diagram, it is known that the highest COPQ of Organizational Factors is 47.8% and there are 11 causes with 6 main causes prioritized for improvement. The suggestions for improvement that can be given to the company include: making Sharing Seasons for seniors and juniors and Managers submitting training, making attention posters to comply with procedures in Material input, making improvements to internal applications / web in the storage area by adding tabs to control Materials which has a shelf life and the implementation of the FIFO (First In First Out) method, performs Reminders and Reports to do 5S/5R before breaks, before and after work, collaborates with other MROs for painting Materials, Pooling parts during post project meetings. Keyword: Quality; Six Sigma; critical to quality; Defect Per Million Opportunities (DPMO); Level Sigma; Cost of poor quality; process maintenance; DMAIC; RCFA; MRO; aircraft maintenance Industri penerbangan khususnya transportasi udara dikatakan adalah transportasi yang paling aman. Untuk menunjang keselamatan penerbangan setiap maskapai harus memerhatikan kelaikudaraan. Dalam hal ini, diperlukannya perawatan pesawat secara berkala. PT GMF AeroAsia Tbk adalah salah satu perusahaan yang bergerak di bidang pelayanan jasa maintenance, repair, dan overhaul (MRO) terbesar di Indonesia. Namun tidak bisa dipungkiri dalam proses maintenance, khususnya dinas narrowbody base maintenance mengalami kejadian cost of poor quality (COPQ). Pada tahun 2020 dinas narrowbody base maintenance mengalami kejadian COPQ pada proses perawatan pesawat sebanyak 14 kejadian dan sebanyak 2229,953 Material dan chemical yang expired. Dengan adanya kejadian COPQ tersebut penelitian ini bertujuan untuk mengetahui COPQ tertinggi dan penyebab terjadinya COPQ, serta memberikan rekomendasi usulan perbaikan dengan metode DMAIC (Define, Measure, Analyze, Control). Berdasarkan hasil perhitungan menggunakan diagram pareto diketahui COPQ tertinggi dari Organizational Factors sebesar 47,8% dan ada 12 penyebab dengan 6 penyebab utamanya yang diprioritaskan untuk dilakukan perbaikan. Usulan perbaikan yang dapat diberikan kepada perusahaan, antara lain: membuat Sharing Season dari senior dan junior serta Manager mengajukan training, membuat poster perhatian untuk selalu sesuai prosedur dalam input Material, melakukan improvement terhadap aplikasi / web internal pada storage area dengan menambahkan tab untuk mengontrol Material yang memiliki shelf life dan diimplementasikannya metode FIFO (First In First Out), melakukan reminder dan report untuk selalu melakukan 5S/5R pada saat sebelum istirahat, sebelum dan sesudah berkerja, melakukan kerjasama dengan MRO lain untuk Material painting, Pooling part ketika rapat post project.
