Analisis Pengendalian Kualitas produk silicone Suku Cadang Mesin Popok Dengan menggunakan Metode Statistical Quality Control (SQC) Di PT.Sugema Kurnia Mas

Abstract.Sugema Kurnia Mas is a silicone spare parts manufacturer for diaper machines. In its production activities, Quality Control has not yet been implemented, resulting in a high number of defective products that cannot be recycled. The purpose of this study is to determine the Quality Control practices at PT. Sugema Kurnia Mas and to analyze them using the Statistical Quality Control (SQC) method. This research uses a quantitative descriptive approach, with data collection techniques including observation, interviews, and documentation. The stages of data analysis using the SQC method involve the creation of a check sheet, histogram, scatter chart, Pareto chart, Np control chart, and fishbone diagram.The results of the study show that there are three main types of defects in the silicone spare parts for diaper machines: irregular shape, nonconforming diameter, and deviated weight. The fishbone diagram indicates that the root causes of these defects stem from factors such as human error, methods, machinery, materials, and environment. The Pareto chart reveals that the most dominant defect is deviated weight, accounting for 41% of the total defects. The analysis of the Np control chart indicates the presence of special causes of variation in the Quality Control process, primarily due to the absence of Standard Operating Procedures (SOPs) in the company's operations. Recommended actions to reduce defective products include developing and implementing SOPs, providing workforce training, utilizing the AKS type HTM634 slicer machine, and modifying the grinding machine. Abstrak PT. Sugema Kurnia Mas merupakan industri silicone suku cadang mesin popok yang dalam kegiatan produksinya masih belum disertai pengendalian kualitas sehingga masih terdapat banyak produk cacat yang tidak bisa di daur ulang kembali. Tujuan dari penelitian ini untuk mengetahui bagaimana pengendalian kualitas yang dilakukan PT. Sugema Kurnia Mas, serta analisisnya menggunakan metode statistical Quality Control (SQC). Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan teknik pengumpulan data yakni observasi, wawancara, dan dokumentasi.
