Sistem pendinginan merupakan komponen penting dalam berbagai proses industri yang mempunyai peranan untuk menjaga suhu peralatan dan kinerja proses agar tetap optimal. Kualitas air yang digunakan dalam sistem ini harus mampu memastikan efisiensi operasional dan meminimalkan risiko kerusakan pada peralatan. Analisis kualitas air pada cooling water menjadi sangat penting untuk memantau dan mengendalikan beberapa parameter kunci dalam kualitas air agar tetap dalam batas yang aman dan optimal. Tujuan dari penelitian ini adalah menganalisa kualitas cooling water pada PT. XYZ Surabaya berdasarkan beberapa parameter diantaranya pH, TDS, turbidity, M-alkalinitas, Ca-hardness, total-hardness, LSI (Langelier Saturation Index), dan RSI (Ryznar Stability Index). Metode penelitian yang digunakan terdiri dari tiga tahapan yaitu tahap pengambilan sampel, tahap persiapan, dan tahap analisis. Pengambilan sampel dilakukan dengan mengambil sampel cooling water pada pabrik tersebut. Sedangkan tahap persiapan dilakukan dengan melakukan kalibrasi terhadap alat-alat instrumentasi yang digunakan. Selanjutnya dilakukan tahap analisa terhadap beberapa parameter kualitas air tersebut. Hasil analisa menunjukkan bahwa cooling water PT. XYZ Surabaya memiliki nilai pH, TDS, turbidity, M-alkalinitas, Ca-hardness, total-hardness, LSI, dan RSI berturut-turut sebesar 6,54; 544 ppm; 1,34 NTU; 236,88 ppm; 62 ppm; 16 ppm; -0,77; dan 8,1. Dari hasil yang diperoleh menunjukkan bahwa air memiliki tingkat korosifitas yang tinggi namun tidak terbentuk kerak.
