Abstract

Abstrak UMKM Udin Leather yang berfokus pada produksi dompet kulit sistem make to order mengalami dua jenis cacat dominan, yakni potongan tidak presisi dan jahitan tidak rapi. Penelitian ini bertujuan mengidentifikasi akar penyebab cacat serta menyusun strategi perbaikan dengan pendekatan Six Sigma dan Root Cause Analysis melalui tahapan DMAIC. Hasil analisis menunjukkan nilai DPMO sebesar 10.667 dan level sigma 3,59, yang mengindikasikan perlunya peningkatan kualitas. FMEA mengungkap bahwa faktor manusia, mesin, dan metode menjadi penyebab utama, dengan jahitan tidak rapi sebagai masalah paling signifikan RPN tertinggi: 120. Rekomendasi difokuskan pada pelatihan tenaga kerja, perawatan mesin rutin, dan penerapan SOP yang ketat. Kata kunci: Six Sigma, Root Cause Analysis, DMAIC, FMEA Abstract Udin Leather UMKM which focuses on the production of leather wallets using the make-to-order system experiences two dominant types of defects, namely imprecise cuts and untidy stitching. This study aims to identify the root causes of defects and develop improvement strategies using the Six Sigma and Root Cause Analysis approaches through the DMAIC stages. The results of the analysis show a DPMO value of 10,667 and a sigma level of 3.59, which indicates the need for quality improvement. FMEA revealed that human, machine, and method factors were the main causes, with untidy stitching as the most significant problem with the highest RPN: 120. Recommendations focused on workforce training, routine machine maintenance, and strict implementation of SOPs. Keywords: Six Sigma, Root Cause Analysis, DMAIC, FMEA
