      Abstract
      Persaingan terjadi melalui kebijakan harga, diferensiasi produk, kebijakan waktu pengiriman, serta mutu bahan baku maupun produk jadi. Salah satu faktor kunci dalam kesuksesan persaingan industri adalah penerapan pengendalian kualitas yang efektif. Selama proses produksi produk Cap Fliptop pada Lini Inject di PT Natama Plast, terdapat beberapa permasalahan kualitas berupa terjadinya defect pada proses produksi produk. Penelitian ini bertujuan untuk melakukan analisis pengendalian kualitas dan implementasi perbaikan terhadap masalah defect/reject pada produk Cap FlipTop di PT Natamas Plast. Dalam membantu pemecahan permasalahan defect yang terjadi pada proses produksi produk cap fliptop, PT Natamas Plast dapat menggunakan metode six sigma sebagai strategi perbaikan produktifitas produksi dalam menurunkan jumlah produk yang mengalami defect. Hasil penelitian menunjukkan bahwa perhitungan nilai sigma setelah dilakukan perbaikan pada bulan Maret 2025, diperoleh tingkat nilai sigma meningkat sebesar 3,90. Nilai sigma ini meningkat sebesar 0,30 dari yang awalnya sebesar 3,60. Hal ini menandakan bahwa tindakan impelementasi perbaikan yang diambil berjalan secara stabil dan cukup konsisten. Terjadi juga penurunan nilai DPMO menjadi 7,178, penurunan ini cukup signifikan dalam menunjukan indeks positif terhadap penurunan jumlah cacat produk setelah proses produksi berjalan.
       
      Competition occurs through pricing policies, product differentiation, delivery time policies, as well as the quality of raw materials and finished products. One key factor in the success of industrial competition is the implementation of effective quality control. During the production process of Fliptop Cap products on the Injection Line at PT Natama Plast, several quality issues have arisen, resulting in defects in the production process. This study aims to analyze quality control and implement improvements to address the defect/reject issues with Fliptop Cap products at PT Natamas Plast. To help resolve the defects occurring during the production of Fliptop cap products, PT Natamas Plast can utilize the Six Sigma method as a strategy to enhance production productivity and reduce the number of defective products. The results of the study indicate that after improvements were made in March 2025, the sigma value calculation showed an increase to 3.90. This sigma value has increased by 0.30 from the initial value of 3.60. This indicates that the implementation of improvement actions is progressing steadily and consistently. Additionally, there was a decrease in the DPMO value to 7,178, which is a significant reduction that reflects a positive index regarding the decrease in the number of product defects after the production process has been ongoing.
