| Abstract: | Penelitian ini bertujuan untuk mengidentifikasi faktor utama penyebab cacat produk Shaft di PT Tanah Sumber Makmur dan merumuskan strategi pengendalian kualitas yang tepat guna menurunkan tingkat ketidaksesuaian produk. Dengan tingkat produk Not Good (NG) mencapai 11,53% pada Oktober 2024, jauh melebihi batas toleransi 2%, metode Seven Tools, Pairwise Comparison, dan FMEA digunakan dalam analisis. Hasilnya menunjukkan bahwa cacat dominan berupa ukuran tidak sesuai (51%), yang utamanya disebabkan oleh faktor manusia seperti minimnya pengawasan dan rendahnya motivasi kerja. Temuan FMEA mengungkap aktivitas pemeliharaan alat potong sebagai risiko tertinggi (RPN 795), sehingga direkomendasikan penerapan checklist harian pada mesin CNC untuk mencegah ketidaksesuaian produk. Hasil penelitian menekankan pentingnya perbaikan aspek SDM dan pengawasan teknis dalam penguatan sistem kualitas perusahaan. This research aims to identify the key factors contributing to product defects in Shaft production at PT Tanah Sumber Makmur and to formulate an effective quality control strategy to reduce the defect rate. In October 2024, the percentage of Not Good (NG) products reached 11.53%, significantly exceeding the acceptable threshold of 2%. The analysis was carried out using the Seven Quality Control Tools, supported by Pairwise Comparison and Failure Mode And Effect Analysis (FMEA). The most frequent defect was dimensional inaccuracy (51% of total defects), largely attributed to human-related issues such as lack of machine tool monitoring, low work motivation, and suboptimal work culture. FMEA results indicated that inadequate maintenance and tool replacement posed the highest risk, with a Risk Priority Number (RPN) of 795. As a preventive measure, the study recommends implementing a daily checklist for CNC machine operators to ensure consistency in product quality. Overall, the findings highlight the need for better human resource management and stronger technical supervision to improve the company's quality management system. |
