Analysis of Quality Improvement of Herbal Medicine Products from Microbial Contaminants Using the PDCA Method with the QCC Approach

This research aims to analyse the quality improvement of herbal medicine from microbial contaminants. There are 2 types of microbial contamination found in many traditional drinks, namely: bacteria (TPN) and fungi (AKK). Therefore, it is necessary to improve the quality and process of herbal medicine using the PDCA method. QCC approach is conducted in one of the herbal medicine producers in Indonesia. Through these improvements, the results of a significant reduction in microbial contamination in the powdered herbal products are obtained. ALT values before repair were 15 x 103 col/g and AKK 5.6 x102 col/g to 5.58 x 103 col/g for ALT and 0.9 x102 col/g for AKK after repair.
