Abstract

Dalam perekonomian dunia, sektor jasa memiliki peranan yang cukup signifikan. Salah satu bentuk perusahaan jasa adalah perusahaan jasa perawatan dan perbaikan (maintenance and repair) peralatan, di mana ketersediaan suku cadang merupakan salah satu pendukung operasional yang penting. Manajemen supply chain mendorong terjadinya integrasi antar fungsi, di mana pendekatan berbasis proses (process-based approach) banyak digunakan untuk merancang sistem pengukuran kinerja supply chain. Salah satunya adalah model SCOR, yang sebagian besar mengacu pada kegiatan-kegiatan dalam industri manufaktur. Namun, belum banyak penelitian yang membahas pengukuran kinerja supply chain pada perusahaan jasa, khususnya yang berkaitan dengan supply chain suku cadang pada perusahaan maintenance and repair. Penelitian ini mengambil studi kasus pada perusahaan jasa maintenance and repair peralatan navigasi kapal. Pembobotan metrik dengan metode perbandingan berpasangan (pairwise comparison) dalam AHP memiliki beberapa kelemahan, antara lain skala bobot yang tidak seimbang (distribusi rasio perbandingan yang tidak sama) serta penggunaan rasio diskret yang dapat menghilangkan kesamaran (fuzziness) dan kerancuan (ambiguity) dalam penilaian manusia. Dalam penelitian ini, himpunan fuzzy digunakan untuk melakukan scoring dan weighting. Hasil pengukuran kinerja kemudian ditindaklanjuti dengan analisis inisiatif perbaikan menggunakan pendekatan Quality Function Deployment (QFD). Berdasarkan model proses supply chain suku cadang, proses inti dalam model SCOR disesuaikan menjadi proses plan, source, exchange, utilize, dan deliver. Untuk mendukung proses perhitungan, dirancang beberapa fungsi menggunakan Matlab. Hasil penelitian menunjukkan bahwa kemampuan supply chain dengan indeks kinerja terkecil adalah supply chain reliability (keandalan), dengan nilai 5,773 pada skala 0–10. Metode QFD melalui matriks House of Quality (HOQ) menunjukkan bahwa prioritas pertama karakteristik kinerja yang perlu diperbaiki adalah proses pemilihan supplier karena memberikan kontribusi terbesar terhadap peningkatan keandalan supply chain, yaitu sekitar 11,9%. Oleh karena itu, perbaikan perlu dilakukan pada sistem informasi, infrastruktur teknologi informasi (IT), dan kemampuan sumber daya manusia (SDM).

The service sector plays a significant role in the global economy. One type of service company is an equipment maintenance and repair company, where spare-parts availability is an important factor supporting operational activities. Supply chain management promotes integration among organizational functions, and a process-based approach is widely used to develop supply chain performance measurement systems. One commonly used tool is the Supply Chain Operations Reference (SCOR) model, which has primarily been applied to activities in manufacturing industries. However, relatively few studies have addressed supply chain performance measurement in service companies, particularly those involving spare-parts supply chains in maintenance and repair companies. This study examines the spare-parts supply chain processes in a maintenance and repair company specializing in marine navigation equipment. The pairwise comparison approach in the Analytical Hierarchy Process (AHP) has several limitations, including an unbalanced preference scale, in which the distribution of comparison ratios is not uniform, as well as the use of discrete ratios that may fail to accommodate fuzziness and ambiguity in human judgment. Therefore, this study uses fuzzy sets for performance scoring and weighting. The performance measurement results are subsequently followed by an analysis of improvement initiatives using the Quality Function Deployment (QFD) approach. Based on the spare-parts supply chain process model, the core processes of the SCOR model are modified into plan, source, exchange, utilize, and deliver. To support the calculation process, several Matlab-based functions are developed. The results show that supply chain reliability has the lowest performance index, with a score of 5.773 on a scale of 0–10. The QFD method using the House of Quality (HOQ) matrix indicates that the first priority for performance improvement is the supplier selection process because it provides the greatest contribution to improving supply chain reliability, accounting for approximately 11.9%. Improvement efforts should therefore focus on the information system, IT infrastructure, and human resource capabilities.
