This study aims to determine the effect of post-production storage time on the types and total number of contaminant bacteria in tofu at room temperature. The study was conducted using a descriptive method with samples of tofu produced conventionally and stored at room temperature for 1, 4, 7, and 10 hours. The results showed four types of contaminant bacteria, namely Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, and Pseudomonas laetrolens. The total number of bacteria fluctuated with an average of 123 × 10³ cells/ml at 1 hour, decreased to 110 × 10³ cells/ml at 4 hours, increased to 151 × 10³ cells/ml at 7 hours, and decreased again to 116 × 10³ cells/ml at 10 hours. Although the ALT value was still below the SNI threshold (1 × 10⁶ CFU/gram), the presence of pathogenic bacteria indicated a potential health risk if tofu was stored for too long at room temperature. The conclusion of this study was that storage time affected the type and number of bacteria in tofu, with the highest number at 7 hours, so the product should be consumed immediately or stored in cold conditions to maintain safety and quality. The results of this study were contributed in the form of a Student Worksheet (LKPD) for Grade X Phase E Odd Semester on the subject of Bacteria and Their Roles. Keywords: tofu, bacteria, storage time, biology learning
