Total plate count test showed that the highest number was found on total bacterial brand of R with  49x 106 cfu/g. In accordance with the Decree of the Minister of Health Nomor1098 / Minister / SK / VII/89 on the Limits of Microbial Contamination in Food, number of bacteria E. Required coli cells per gram of sample 0 food and 0 cells per 100 ml of sample drinks as well as total plate count (total bacteria) by the Indonesian BPOM about the type and maximum limit microbial contamination in food HK.00.06.1.52.40011 numbers in 2009 for the number of bacteria colonies / gram sample is 1x104 cfu / g.
