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%. .

Along with high orders from customers for shoe products in apparel companies, the production department must also support productivity results. The production process has experienced several problems, including the number of work accidents and potential levels of work accidents, and the absence of safe work accident control measures in the cutting die area for the shoe production process. The purpose of this study is to analyze the types of work accidents and provide recommendations for controlling sources of hazard to reduce or eliminate the level of risk involved in the shoe molding process. The method used in this study uses the Hazard Identification Risk Assessment and Determining Control (HIRADC) method combined with the Focus Group Discussion (FGD) method. The findings of this study have obtained data before repair with 16 hazard potentials consisting of 6 medium hazard potentials and 10 low hazard potentials. Improvements that have been made in accident risk control for each potential hazard include technical controls, administrative controls, and document controls. The results of this study resulted in a reduction in the risk of work accidents after repairs to 16 low hazard potentials and no moderate hazard potentials. So from these results, it can be concluded that the decrease in risk level from medium risk to low risk proves the success of corrective actions.

Dalam memilih dan membeli tanah liat, Usaha Mikro Kecil dan Menengah (UMKM) kerajinan gerabah memiliki empat pemasok tanah liat yang berlokasi di Provinsi Daerah Istimewa Yogyakarta. Seiring berjalannya pembelian bahan baku tanah liat, muncul masalah terkait kualitas tanah liat. Masalah tersebut adanya pemasok tanah liat yang memberikan kualitas tanah liat tidak ulet dan sulit dibentuk yang mengakibatkan penurunan kualitas produk gerabah dan terjadinya peningkatan biaya produksi karena melakukan pembelian tanah liat kembali. Penelitian ini bertujuan untuk memilih prioritas pemasok tanah liat yang memiliki kualitas bahan baku yang baik dan membuat usulan desain Standar Operational Procedure (SOP) pengadaan bahan baku gerabah yang dapat meningkatkan kualitas produk dan mengurangi biaya produksi. Penelitian ini menggunakan kombinasi metode yaitu metode kaizen berupa diagram Pareto dan diagram Fishbone dalam menganalisa permasalahan yang muncul. Kemudian pada tahap pengolahan data, metode yang digunakan adalah metode Analytical Hierarchy Process (AHP) yang multi kriteria untuk menentukan kualitas bahan baku dari empat pemasok dengan bantuan dua responden yang merupakan ahli dibidang pembelian bahan baku. Penelitian ini telah membuat desain SOP pengadaan barang pada departemen produksi UMKM gerabah. Hasil dari penelitian ini berupa urutan prioritas pemasok tanah liat yang memiliki nilai bobot tertinggi dari hasil pengolahan data dengan metode AHP yaitu, yang pertama pemasok GE (0,5814), yang kedua adalah pemasok KA (0,1890), kemudian pemasok GD (0,1246), dan yang terakhir adalah pemasok MA (0,1051). AbstractIn selecting and purchasing clay, Micro, Small and Medium Enterprises (MSMEs) for pottery crafts have four clay suppliers located in the Special Region of Yogyakarta Province. As the purchase of clay raw materials progresses, problems arise regarding the quality of the clay. The problem is that there are clay suppliers who provide quality clay that is not ductile and difficult to form, which results in a decrease in the quality of pottery products and an increase in production costs due to repurchasing clay. This research aims to select priority clay suppliers who have good quality raw materials and make a design proposal for a Standard Operational Procedure (SOP) for the procurement of pottery raw materials that can improve product quality and reduce production costs. This research uses a combination of methods, namely the kaizen method in the form of Pareto diagrams and Fishbone diagrams in analyzing problems that arise. Then at the data processing stage, the method used was the multi-criteria Analytical Hierarchy Process (AHP) method to determine the quality of raw materials from four suppliers with the help of two respondents who were experts in the field of purchasing raw materials. This research has created an SOP design for procurement of goods in the pottery MSME production department. The results of this research are in the form of a priority order for clay suppliers that have the highest weight value from the results of data processing using the AHP method, namely, the first is the GE supplier (0.5814), the second is the KA supplier (0.1890), then the GD supplier (0.1246), and the last one is the MA supplier (0.1051).Keywords: analytical hierarchy process; kaizen; supplier selection; clay; MSMEs
