This study aims to determine the effect of post-production storage time on the type and total number of contaminant bacteria in soy milk stored at room temperature. The method used in this study is a descriptive, the results of the study show that there are five types of pathogenic bacteria, namely: Bacillus sp, Escherichia coli, Enterobacter cloacae, Klebsiella sp, and Pseudomonas sp. And the non-pathogenic ones are only one type, namely: Lactobacillus sp. The total number of bacteria contained in the 1st hour soy milk sample was 25 x {10}^3 cells/ml, the 4th hour amounted to 141 x {10}^3 cells/ml and the 7th hour amounted to 176 x {10}^3 cells/ml, and the 10th hour amounted to 164 x {10}^3 cells/ml. Results The number of bacteria calculated and compared with the standard of microbial contamination test is in the 1st hour which is 2.5 x {10}^4 CFU/ml, the 4th hour is 1.405 x {10}^5 CFU/ml, the 7th hour is 1.755 x {10}^5CFU/ml and the 10th hour is 1.635 x {10}^5 CFU/ml. Between these hours, all of them are still eligible according to the Indonesian National Standard (SNI). Based on the results of the study, it can be concluded that even though the number of requirements of the Indonesian National Standard (SNI) No. 01-3839 of 1995 is 1 x {10}^6\ CFU/ml, there are still pathogenic bacteria such as Bacillus sp, Escherichia coli, Enterobacter cloacae, Klebsiella sp, and Pseudomonas sp in the soy milk samples so that soy milk is not yet suitable for consumption and the storage time of soy milk after the production process affects the type and The total number of contaminant bacteria that grow if soy milk is stored at room temperature. The results of this research were contributed in the form of Student Worksheets (LKPD) class X Phase E Odd Semester on material about Bacteria. Keywords: Soy Milk, Bacteria, Storage Time.
