Abstract: One method to reduce the number of bacteria and kill pathogenic bacteria is pasteurization. The purpose of this study is to get the best pasteurization method to reduce the number of bacteria and meet the Indonesian national standard requirements. This research is a comparative study to compare the methods of HTST (High Temperature Short Time) and LTLT (Low Temperature Long Time) pasteurization using samples of cow’s milk from the people’s dairy farms in Sunten Jaya Village, Lembang. The results showed the average total colonies number of cow’s milk before pasteurization was1,19x104 CFU/m, post pasteurization using LTLT method was 8.8x102 CFU/ml, and HTST method was 3.2x102CFU/ml. There was a significant decrease in the number of bacteria after pasteurization, with a p-value of 0.027 after being analyzed by the Kruskal Wallis test (p-value < 0.05).In addition, there was a significant difference between the total colonies number of HTST and LTLT post-pasteurization after being analyzed by the Mann Whitney test, with p-values = 0.05 (p-value < 00.05). Thus the HTST method is the best method in reducing the number of bacterial colonies in cow’s milk from Sunten Jaya Village, Lembang.
