Proses packing produk Astor Singles 12,5 g pada Mesin Packing B6 di PT MAY masih menghasilkan reject cello yang memengaruhi penggunaan material dan kestabilan proses. Penelitian ini bertujuan menganalisis kondisi awal pengendalian kualitas, mengidentifikasi penyebab utama reject, menentukan setting tinggi sensor yang menghasilkan reject terendah, serta menyusun pengendalian proses setelah perbaikan. Penelitian menggunakan metode Define, Measure, Analyze, Improve, dan Control (DMAIC) yang dipadukan dengan Design of Experiments (DOE). Data awal berasal dari Agustus 2025 sampai Januari 2026. Analisis menggunakan check sheet, Diagram Pareto, P-Chart, DPMO, Fishbone Diagram, Five Why Analysis, dan FMEA. Dari 108.936.576 unit produksi ditemukan 286.740 unit reject atau 0,2632%. Overlap menjadi jenis reject terbesar sebesar 35,67% dengan RPN tertinggi 648. Eksperimen tinggi sensor pada tujuh level dengan lima replikasi menunjukkan setting 3,0 mm menghasilkan rata-rata reject terendah sebesar 4,4%. One-Way ANOVA menghasilkan F-Value 5,24 dan P-Value 0,001. Setelah setting 3,0 mm diterapkan dan dikendalikan, reject produksi turun menjadi 0,09426%, atau berkurang 64,19%.
