| Abstract: | UD. Eka Profil Gypsum merupakan UMKM yang menghadapi masalah tingginya tingkat produk cacat, sehingga memengaruhi kualitas dan efisiensi produksi. Penelitian ini bertujuan untuk mengurangi jumlah produk cacat dengan menerapkan metode Six Sigma melalui pendekatan DMAIC (Define, Measure, Analyze, Improve, Control). Data diperoleh melalui observasi, wawancara, dan dokumentasi, lalu dianalisis menggunakan diagram Pareto, fishbone, dan peta kendali. Hasil analisis menunjukkan bahwa jenis cacat paling dominan adalah retak, dengan nilai DPMO sebesar 26.461,80 dan level sigma 3,44. Faktor penyebab cacat berasal dari manusia, metode, material, dan alat. Dari berbagai upaya perbaikan, penyusunan Standard Operating Procedure (SOP) menjadi solusi utama untuk menekan variasi proses kerja yang selama ini tidak seragam. SOP disusun secara sistematis untuk mengatur proses produksi dari tahap pencampuran hingga pemotongan, terutama pada proses kritis seperti pengeringan. Implementasi SOP ini menjadi dasar pengendalian mutu yang lebih konsisten. Hasilnya, penerapan metode Six Sigma dengan dukungan SOP berpotensi efektif dalam menurunkan tingkat cacat dan meningkatkan kualitas produksi. UD. Eka Profil Gypsum is a small manufacturing enterprise (SME) that faces a high rate of defective products, impacting both quality and production efficiency. This study aims to reduce product defects by applying the Six Sigma method using the DMAIC (Define, Measure, Analyze, Improve, Control) approach. Data were collected through observation, interviews, and documentation, then analyzed using Pareto diagrams, fishbone diagrams, and control charts. The results show that the most dominant defect is cracking, with a DPMO value of 26,461.80 and a sigma level of 3.44. The main causes of defects stem from human, method, material, and equipment factors. Among the various improvement efforts, the development of a Standard Operating Procedure (SOP) was identified as the key solution to reduce process variation caused by inconsistent work practices. The SOP was systematically designed to standardize each stage of production, especially in critical processes such as drying and cutting. Its implementation provided a structured foundation for more consistent quality control. As a result, the application of Six Sigma supported by SOP potentially effective in reducing defect rates and improving product quality. |
