Abstract
Penelitian ini bertujuan untuk menurunkan tingkat cacat pada proses produksi pupuk granule phosphate dan kalium di PT X, yang meliputi cacat berukuran terlalu kecil (undersize), terlalu besar (oversize), dan tidak berbentuk (misshapen). Metode PDCA digunakan sebagai pendekatan perbaikan kualitas melalui tahapan Plan, Do, Check, dan Action. Analisis Pareto, Histogram, serta Diagram Fishbone diterapkan untuk mengidentifikasi jenis cacat dominan dan akar penyebabnya, sedangkan tindakan perbaikan difokuskan pada penetapan SOP baru, pelatihan operator, serta penambahan titik inspeksi kualitas pada setiap proses produksi. Hasil penelitian menunjukkan penurunan signifikan rata-rata cacat phosphate dari 802 kg menjadi 319 kg dan stabil pada batas kendali, serta perbaikan konsistensi mutu pada produk kalium. Penelitian ini merekomendasikan pengembangan monitoring kualitas pada setiap prosesnya sehingga mendapatkan produk yang bermutu
