Abstract

Mesin screw compressor merupakan salah satu peralatan utilitas penting dalam industri manufaktur karena berfungsi menyediakan udara bertekanan untuk mendukung sistem pneumatik, aktuator, kontrol, dan peralatan bantu produksi. Gangguan pada mesin ini dapat menyebabkan terhentinya proses produksi dan menurunkan produktivitas perusahaan. Penelitian ini bertujuan untuk mengoptimalkan sistem perawatan mesin screw compressor menggunakan metode Reliability Centered Maintenance (RCM). Metode yang digunakan meliputi analisis downtime, perhitungan Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), availability, Failure Mode and Effects Analysis (FMEA), Logic Tree Analysis (LTA), serta penyusunan keputusan perawatan berbasis RCM. Berdasarkan data historis Januari sampai Desember 2025, total downtime mesin mencapai 740 jam dengan 33 kejadian kerusakan. Hasil perhitungan menunjukkan nilai MTBF sebesar 243,03 jam, MTTR sebesar 22,42 jam, dan availability sebesar 91,55%. Hasil FMEA menunjukkan bahwa kegagalan dominan adalah temperatur tinggi dengan RPN 405, screw noise dengan RPN 336, dan motor compressor short dengan RPN 300. Usulan kebijakan perawatan berbasis RCM meliputi condition-based maintenance, preventive maintenance, dan time-based maintenance sesuai tingkat risiko dan konsekuensi kegagalan. Hasil evaluasi menunjukkan bahwa penerapan usulan RCM berpotensi menurunkan downtime menjadi 513 jam atau sebesar 30,68% dan meningkatkan availability menjadi 94,14%. Dengan demikian, metode RCM dapat digunakan sebagai pendekatan sistematis untuk meningkatkan keandalan mesin dan produktivitas sistem produksi.

Abstract

Service quality evaluation in tour and travel services requires not only identifying attributes that customers consider important but also understanding how their fulfillment or absence affects customer satisfaction. Although Importance–Performance Analysis (IPA) and the Kano Model have been applied in various service contexts, their combined application to translate customer evaluations into actionable improvement priorities for local tour and travel service providers remains contextually underexplored. This study evaluates service quality improvement priorities at CV Mutiara Katulistiwa using an integrated IPA–Kano approach. A quantitative survey was conducted with 99 customers selected through purposive sampling. Twenty-five service attributes covering tangibles, reliability, responsiveness, assurance, and empathy were evaluated based on customer importance, perceived performance, and satisfaction characteristics. IPA identified five attributes in the Concentrate Here quadrant, while the Kano Model classified the attributes into Must-be, One-dimensional, and Indifferent categories. The integrated analysis identified on-order service availability and tourism service security as critical mandatory priorities, whereas complaint responsiveness, service information availability, and tour guide competence emerged as performance-improvement priorities. The integrated IPA–Kano approach provides a structured prioritization mechanism that distinguishes attributes requiring immediate corrective action from those that should be maintained or further developed. Rather than proposing a new integration method, this study extends its application to a local tour and travel service context and demonstrates how integrated customer evaluations can be translated into a practical service-improvement roadmap for small service providers.
