Microbial and Biochemical Assessment of Coffee Milk Production Quality at Jago Coffee Using Total Plate Count and Methylene Blue Reduction Test

---

This internship project aims to evaluate the microbial quality of coffee milk during its production
at Jago Coffee. The project employs the Total Plate Count (TPC) and Methylene Blue Reduction
Test (MBRT) to assess bacterial load and microbiological activity. The TPC results obtained for the
cooling and filling & sealing processes comply with the SNI (Standar Nasional Indonesia)
standards, as their TPC values fall within the acceptable range of 5 log cfu/ml. However, the
mixing process, which is considered a Critical Control Point (CCP), fails to meet the SNI standards
as its value exceeds the required limit. Consequently, the overall product does not meet the TPC
requirement. In contrast, the MBRT results indicate satisfactory microbiological quality and
compliance with the SNI guidelines. The reduction time observed during the mixing, cooling,
filling, and sealing processes ranges from 7 to 10 hours, placing it under the category of
heat-treated milk according to the SNI guidelines. No significant correlation is observed between
TPC and MBRT. This study highlights the importance of heat treatment during the mixing process
to ensure product safety and quality. Further research is recommended to explore the
relationship between TPC and MBRT in the production of coffee milk.
