      Abstract
      Penelitian ini bertujuan untuk mengendalikan kualitas produk ajitama di PT XYZ menggunakan metode Statistical Quality Control (SQC). Proses produksi ajitama menunjukkan permasalahan utama berupa permukaan telur tidak halus setelah tahap pengupasan, sehingga produk dinyatakan reject. Penelitian ini menggunakan metode SQC untuk memantau kinerja proses produksi dan mengidentifikasi penyebab ketidaksesuaian produk. Hasil penelitian menunjukkan bahwa faktor penyebab utama ketidaksesuaian berasal dari aspek manusia, mesin, dan material. Faktor manusia meliputi pengerjaan dengan tergesa-gesa dan kurangnya pemahaman terhadap prosedur kerja standar. Dari aspek mesin, ketidakkonsistenan suhu pada water bath memengaruhi tekstur putih telur, sedangkan dari aspek material, penggunaan bahan baku telur yang terlalu segar menyebabkan kesulitan saat pengupasan karena pH putih telur masih rendah sekitar 7,0 - 7,6. Tindakan perbaikan dilakukan melalui pelatihan rutin bagi operator, penetapan standar suhu pendinginan 0–10°C, serta penyimpanan telur selama beberapa hari sebelum perebusan untuk menyeimbangkan pH. Hasil evaluasi pascaperbaikan menunjukkan bahwa proses produksi ajitama berada dalam kondisi terkendali secara statistik dengan penurunan signifikan pada tingkat produk cacat.
       
      This study aims to control the quality of ajitama products at PT XYZ using the Statistical Quality Control (SQC) method. The ajitama production process shows a major problem in the form of uneven egg surfaces after the peeling stage, resulting in the product being rejected. This study uses the SQC method to monitor production process performance and identify the causes of product nonconformity. The results of the study show that the main factors causing nonconformity are human, machine, and material aspects. Human factors include rushing and a lack of understanding of standard work procedures. From the machine aspect, the inconsistency of the water bath temperature affected the texture of the egg whites, while from the material aspect, the use of eggs that were too fresh caused difficulties during peeling because the pH of the egg whites was still low, around 7.0–7.6. Corrective actions were taken through routine training for operators, setting a cooling temperature standard of 0–10°C, and storing eggs for several days before boiling to balance the pH. Post-improvement evaluation results showed that the ajitama production process was statistically controlled with a significant decrease in the defect rate.
