Abstract: Kualitas produk merupakan faktor penting bagi UMKM dalam menjaga kepuasan konsumen dan daya saing usaha. UMKM Karinee Bakery masih menghadapi permasalahan kualitas pada produk Bolen, khususnya cacat Bolen gosong dan Bolen pecah, sehingga diperlukan pengendalian kualitas yang terstruktur. Penelitian ini bertujuan untuk mengukur tingkat kualitas produk Bolen menggunakan metode Six Sigma, mengidentifikasi faktor penyebab utama kecacatan produk, serta menyusun usulan perbaikan proses produksi agar kualitas Bolen lebih konsisten dan jumlah produk cacat dapat diminimalkan. Metode yang digunakan adalah Six Sigma dengan tahapan DMAIC. Data diperoleh melalui observasi lapangan, wawancara, dan dokumentasi data kecacatan selama tiga bulan. Analisis dilakukan menggunakan perhitungan DPMO dan Level Sigma, Diagram Pareto, Fishbone Diagram, serta metode 5W+1H untuk penyusunan usulan perbaikan. Hasil penelitian menunjukkan bahwa tingkat kualitas produk Bolen pada bulan September berada pada level sigma 3,450 dengan nilai DPMO sebesar 25.600. Pada bulan Oktober, level sigma sebesar 3,474 dan nilai DPMO sebesar 24.200, sedangkan pada bulan November level sigma 3,472 dengan nilai DPMO sebesar 24.300. Cacat Bolen gosong menjadi jenis cacat dominan sebesar 72,40%, sedangkan Bolen pecah sebesar 27,60%. Faktor penyebab utama kecacatan berasal dari faktor metode, manusia, dan mesin, terutama akibat belum adanya SOP yang jelas dan distribusi panas oven yang tidak merata. Penerapan usulan perbaikan melalui penyusunan SOP, peningkatan kedisiplinan operator, serta pengendalian proses pemanggangan dan pelepasan Bolen diharapkan mampu menurunkan tingkat kecacatan dan meningkatkan konsistensi kualitas produk Bolen. Product quality is an important factor for UMKM in maintaining customer satisfaction and business competitiveness. UMKM Karinee Bakery still faces quality issues in its Bolen products, particularly burnt and cracked defects, thus requiring structured quality control. This study aims to measure the quality level of Bolen products using the Six Sigma method, identify the main factors causing product defects, and propose process improvement recommendations to achieve more consistent quality and minimize the number of defective products. The method used in this research is Six Sigma with the DMAIC stages. Data were collected through field observations, interviews, and documentation of defect data over a three-month period. The analysis was conducted using DPMO and Sigma Level calculations, Pareto Diagram, Fishbone Diagram, and the 5W+1H method to formulate improvement proposals. The results show that the quality level of Bolen products in September was at a sigma level of 3.450 with a DPMO value of 25,600. In October, the sigma level was 3.474 with a DPMO value of 24,200, while in November the sigma level was 3.472 with a DPMO value of 24,300. Burnt Bolen was the dominant defect type at 72.40%, while cracked Bolen accounted for 27.60%. The main causes of defects were related to method, manpower, and machine factors, particularly the absence of clear SOPs and uneven oven heat distribution. Implementing improvement proposals through SOP development, increased operator discipline, and better control of baking and product release processes is expected to reduce defect rates and improve product quality consistency.
