      Abstract
      PT XYZ memproduksi minuman kemasan air bersoda dengan reject finished goods pada bulan September – Desember 2024 adalah 3,19%. Tujuan penelitian ini adalah untuk mengindentifikasi jenis reject yang sering terjadi, menganalisis faktor penyebab dari reject finished goods air bersoda, dan dapat menentukan saran perbaikan untuk pengendalian mutu reject selama proses produksi. Metode yang digunakan adalah Statistical Quality Control (SQC). Hasil analisis menunjukkan data tidak terkendali dalam bagan kendali P. Analisis diagram pareto menunjukkan jenis reject finished goods terbesar adalah volume kurang sebesar 47,7% yang disebabkan oleh faktor manusia, mesin, material, metode, dan lingkungan. Adapun tutup rusak sebesar 35,5% disebabkan oleh faktor manusia, mesin, material, dan metode. Rekomendasi perbaikan berdasarkan hasil adalah (a) melakukan pelatihan dan sosialisasi Standard Operational Procedure (SOP) start up produksi air bersoda dan instruksi kerja verifikasi mesin, (b) menetapkan jadwal preventive maintenance (c) melakukan inspeksi botol sebelum masuk ke dalam mesin, (d) melakukan verifikasi mesin setiap awal pergantian shift, (e) membuat checklist suhu dan kelembaban, (f) melengkapi informasi checklist verifikasi mesin.
       
      PT XYZ produces packaged soda water with an average of rejected finished goods in September – December 2024 is 3,19%. The purpose of this study is to identify the types of rejects that frequently occur, analyze the factors causing the rejected finished goods of soda water, and determine suggestions for improvements to control the quality of rejects during the production process. The method used is Statistical Quality Control (SQC). The results of the analysis show uncontrolled data in the P control chart. Pareto diagram analysis shows that the largest type of rejected finished goods is insufficient volume of 47,7% caused by human, machine, material, method, and environmental factors. The damaged cap is 35,5% caused by human, machine, material, and method factors. Recommendations for improvement based on the 5 why analysis are (a) conducting training and socialization of the Standard Operational Procedure (SOP) for start-up production of sparkling water and work instructions for machine verification, (b) setting a preventive maintenance schedule (c) checking bottles before entering the machine, (d) verifying the machine at the beginning of each shift, (e) creating a temperature and humidity checklist, (f) completing the machine verification checklist information.
