“…This stage uses data processing to calculate the sigma level for 6 months of data before improvement. The sigma level can be known in advance by calculating Defects per Unit (DPU), Total Opportunities (TOP), Defects per Opportunities (DPO), and Defects Per Million Opportunities (DPMO), and the Sigma Level can be known using the formula (2), (3), ( 4), (5), and (6) [20].…”

“…The data displayed in the Visio software regarding the four-block diagram process are the results of the Sigma and DPMO levels (before and after improvements). The difference between the two data will be visible in the four-block diagram [20]. The formula used to control process capability results can use the formula (10), and (11).…”

The current era provides challenges for several automotive industries to be able to compete and maintain the quality of their products. For four-wheeled automotive companies, satisfying customers regarding the visual appearance of the vehicle body is very important. However, internally, automotive companies still found many defects or failures in painting, amounting to 32.6%. Apart from that, rework also results in additional costs that the company must incur during the painting process. This study aims to clarify types of painting defects, analyze root causes, provide solutions, improve process capabilities, and increase the sigma level in the painting process in the four-wheeled vehicle industry. This study uses the Lean Six Sigma method, which is integrated into the DMAIC approach and other improvement tools. As a result, this study clarifies four critical defects in the orange peel defects of the painting section, craters, melting, and blur. This study has resulted in several corrective action solutions, including tightening supervision of the performance of painting section operators so that they are consistent and committed to working according to the Standard Operational Procedure (SOP) or work instructions that have been created. A competency matrix is used to evaluate operator performance, which is reported to superiors and subordinates by the supervisory department. After carrying out corrective action, this study increased the process capability from 1.17 to 1.92. The higher the capability value, the higher the sigma level. This study also has increased the sigma level from 2.76 to 3.42, meaning an increase of 78%. .

“…e analyze stage is the third step carried out within the DMAIC framework. is stage is carried out to conduct further analysis to determine the causes and effects that occur in the process and determine the source of failure in the production process [17]. At this stage, identification of the highest type of disability is carried out using a Pareto chart.…”

This study explores the application of Six Sigma and data mining methodologies to address the high defect rate in the packaging of Wardah Lightening Powder Foundation. Faced with quality control challenges, the research aims to systematically identify the root causes of packaging defects and develop strategic measures to enhance product quality. Employing a comprehensive Six Sigma approach, the study incorporates various analytical tools, including SIPOC diagrams, Critical-to-Quality (CTQ) characteristics, control charts, Pareto diagrams, and Failure Modes and Effects Analysis (FMEA). These tools facilitate a detailed investigation of the packaging process, highlighting significant failure types and inefficiencies. The research methodology involves an extensive data collection and analysis phase, utilizing data mining techniques to delve into historical defect data. This analysis uncovers underlying patterns and correlations that contribute to packaging failures. Based on these findings, the study proposes targeted interventions to mitigate defect levels. These interventions include the implementation of alarm systems and buzzers on production lines to promptly address issues, and the redesign of ink storage labels for clearer communication and error reduction. The outcomes of this study demonstrate a substantial improvement in packaging quality, evidenced by a marked reduction in defect rates. This enhancement not only contributes to operational efficiency but also plays a crucial role in elevating customer satisfaction levels. The research underscores the effectiveness of integrating Six Sigma with data mining in identifying, analyzing, and resolving quality issues in manufacturing processes. It provides valuable insights for organizations in the packaging industry seeking to optimize their quality control mechanisms and achieve higher standards of product excellence.

PT XYZ merupakan industri manufaktur yang bergerak dibidang furniture. Permasalahan yang terjadi yaitu terdapat produk meja tidak sesuai spesifikasi konsumen sehingga mengakibatkan proses berlebihan dan menambah biaya produksi. Penelitian ini bertujuan untuk mengetahui faktor penyebabkan kecacatan dan usulan pengendalian kualitas produk menggunakan metode six sigma. Penelitian ini menggunakan metode six sigma dengan tahapan DMAIC (Define, Measure, Analyze, Improve, and Control). Menggunakan alat statistic antara lain : Diagram SIPOC, Diagram pareto, p chart, Diagram fishbone, dan usulan perbaikan 5W+1H. Hasil dari penelitian ini diketahui faktor penyebab cacat produk yaitu faktor tenaga kerja, kurangnya pelatihan dan kelelahan karena kepanasan serta berdiri terlalu lama menyebabkan kurang fokus. Faktor metode, kesalahan saat assemblly, kesalahan proses pemotongan, jalur roll kurang baik, dan proses finishing kurang maksimal. Faktor mesin, kestabilan mesin press dan spray gun. Faktor bahan baku, kualitas bahan baku. Faktor lingkungan kerja, debu berterbangan. Berdasarkan analisis 5W+1H usulan perbaikan untuk faktor tenaga kerja, perbaikan waktu istirahat serta penambahan ventilasi, dan pelatihan penggunaan mesin press. Faktor metode, pelatihan penggunaan mesin press, pelatihan pemotongan kayu, perbaikan jalur roll, dan mengoptimalkan proses pengeringan. Faktor mesin, perawatan mesin press dan spray gun secara berkala. Faktor bahan baku, pengawasan kualitas bahan baku. Faktor lingkungan kerja mewajibkan karyawan menggunakan masker.
