Abstract

PT Sicer Indonesia is a ceramic manufacturer company which is produce various types of products such as Glaze, Engobe and Medium. Observations were made on the Titanium Frit (Glaze) production section and Quality Control results. This research aims to determine the factors that cause defects in products, determine corrective actions and reduce the number of product defects. Defects that often occur in Titanium Frit are Less White, Pinhole, Blackspot and Yellowish. Where the largest percentage of defects was in February at 43.2%. Therefore, effective quality control efforts are needed. In this research, the Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) methods were used to identify and analyze defects that occurred. FMEA is used to determine and multiply the severity level, occurrence level and detection level, to obtain a Risk Priority Number (RPN) value which can determine the priority of defects that must be prioritized for repair. The highest RPN defect value is the Pinhole defect with RPN 448.. FTA is used to find out the root cause of the defect that occurs. The main factors causing defects in the Titanium Frit production process consist of 4 factors, human factors are caused by workers who do not work according to SOP, lack of machine maintenance, unstable material quality, and environmental contamination. The results or quality improvement actions taken are carrying out consistent supervision to ensure that workers have worked according to the SOP and carrying out maintenance on materials and machines as a whole regularly before use.

Abstract

PT Pungkook Indonesia One merupakan perusahaan manufaktur tas outdoor dan fashion untuk brand internasional. Proses produksi meliputi cutting, assembling, sewing, packing, hingga ekspor. Penelitian ini berfokus pada bagian assembling dan sewing yang memiliki kondisi kerja kurang nyaman, seperti kebisingan dan suhu ruang yang panas, serta postur kerja yang bervariasi (sebagian pekerja berdiri dan sebagian duduk). Kondisi tersebut berkontribusi terhadap keluhan kelelahan yang berdampak pada kehadiran, produktivitas input–output, dan penurunan kualitas. Penilaian beban kerja fisik dilakukan menggunakan metode Cardiovascular Load (CVL) melalui pengukuran langsung dan tidak langsung pada 20 pekerja (10 pekerja assembling dan 10 pekerja sewing) dengan variasi usia dan berat badan. Hasil menunjukkan rata-rata CVL pada bagian assembling sebesar 14,54% (kategori ringan) dan pada bagian sewing sebesar 18,86% (kategori ringan). Nilai penilaian beban kerja untuk assembling adalah denyut nadi 86,38 denyut/menit, konsumsi oksigen 1,55 L/menit, energi 3,3711 kkal/menit, dan total metabolisme 313,51 kkal/jam; sedangkan pada sewing adalah denyut nadi 91,26 denyut/menit, konsumsi oksigen 1,66 L/menit, energi 3,691 kkal/menit, dan total metabolisme 362,45 kkal/jam. Berdasarkan total metabolisme, beban kerja pada bagian assembling dan sewing termasuk kategori sedang. Perhitungan waktu istirahat optimal berdasarkan pendekatan fisiologis menggunakan konsumsi energi menunjukkan bahwa tidak diperlukan tambahan waktu istirahat (Rt = 0), sehingga waktu istirahat yang tersedia selama 60 menit dinilai sudah mencukupi.

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.
