Abstract

Selama ini, perbaikan kualitas pada sebuah industri manufaktur bogie menggunakan beberapa tools kualitas tradisional secara sekuensial Sebagai organisasi bisnis, perusahaan membutuhkan metode yang komprehensif yang mencakup identifikasi jenis defect yang perlu diprioritaskan hingga rekomendasi langkah perbaikan dengan mempertimbangkan biaya. Pada penelitian terdahulu, Quality Improvement Matrix (QIM) telah dikembangkan sebagai tool terintegrasi berbasis Failure Mode and Effect Analysis (FMEA) dan House of Quality (HOQ). QIM yang terdiri dari dua matriks dapat digunakan untuk perbaikan kualitas secara komprehensif mulai dari identifikasi defect, akar penyebab defect hingga penentuan prioritas langkah perbaikan kualitas. Namun QIM masih memiliki keterbatasan yaitu penilaian Severity dan Difficulty tidak secara eksplisit mempertimbangkan biaya, dan tidak mempertimbangkan parameter Detection. Penelitian ini mengembangkan framework QIM yang diperkaya melalui integrasi konsep Extended FMEA. Pengembangan mencakup tiga aspek utama: (1) penambahan parameter Severity Cost yang mempertimbangkan biaya kegagalan, dan parameter Detection yang mengukur kemampuan sistem mendeteksi akar penyebab defect; (2) pengayaan parameter Difficulty dengan aspek biaya dan waktu implementasi; serta (3) kategorisasi akar penyebab defect berdasarkan kerangka 6M. Selain itu perubahan pada langkah perbaikan kualitas yaitu secara eksplisit menawarkan opsi Jidoka sebagai pilihan metode. Pengembangan QIM baru ini diterapkan untuk membantu perusahaan untuk mengatasi permasalahan defect pada produksi bogie. Hasil analisa teridentifikasi 5 defect dominan dan 32 akar penyebabnya. Urutan prioritas langkah perbaikan kualitas yang direkomendasikan adalah pembuatan SOP, pengadaan pelatihan untuk operator, dan pengembangan Poka Yoke. Berdasarkan umpan balik dari perusahaan menyatakan framework QIM baru dapat membantu perusahaan untuk melakukan perbaikan kualitas. Selain itu, tampilan hasil analisa QIM dalam bentuk dua matriks yang sederhana namun informatif untuk mengkomunikasikan alur proses perbaikan kualitas untuk semua pihak terkait di perusahaan.

Quality improvement in a bogie manufacturing industry has traditionally been carried out using several conventional quality tools applied sequentially. As a business organization, the company requires a comprehensive method that covers the identification of defect types to be prioritized through to the recommendation of improvement actions while taking cost into consideration. In previous research, the Quality Improvement Matrix (QIM) was developed as an integrated tool based on Failure Mode and Effect Analysis (FMEA) House of Quality (HOQ). The QIM, which consists of two matrices, can be used for comprehensive quality improvement, ranging from the identification of defects and their root causes to the prioritization of quality improvement actions. However, the QIM still has limitations: the assessment of Severity and Difficulty does not explicitly consider cost, and the Detection parameter is not taken into account. This research develops an enriched QIM framework through the integration of the Extended FMEA concept. The development covers three main aspects: (1) the addition of a Severity Cost parameter that accounts for the cost of failure, and a Detection parameter that measures the system's ability to detect the root causes of defects; (2) the enrichment of the Difficulty parameter with cost and implementation time aspects; and (3) the categorization of defect root causes based on the 6M. In addition, the quality improvement actions were modified by explicitly offering Jidoka as an optional method. The newly developed QIM was applied to help the company address defect problems in bogie production. The analysis identified 5 dominant defects and 32 root causes. The recommended priority order of quality improvement actions is the development of standard operating procedures, the provision of operator training, and the development of Poka-Yoke. Based on feedback from the company, the new QIM framework can assist the company in carrying out quality improvement. Furthermore, the presentation of the QIM analysis results in the form of two matrices is simple yet informative for communicating the quality improvement process flow to all relevant parties in the company.
