Abstract

One of the tropical diseases often contagious communities is diarrhea. Consumption of drink fermented by lactic acid bacteria, such as synbiotic green cincau drink is known will suppress the growth of diarrhea-causing pathogenic bacteria. The aims of this study were to determine the ability of the antibacterial activity of synbiotic green cincau drink against pathogenic bacteria that cause diarrhea and the effect of storage duration on the ability of antibacterial activity of synbiotic green cincau drink. This research was conducted to obtain qualitative data on the antibacterial activity of synbiotic green cincau drink against diarrhea-causing pathogens bacterial (Staphylococcus aureus, Salmonella sp., Bacillus cereus, and Escherichia coli). The product was stored for 28 days in the cold temperature (10oC). Observations were carried out once every 7 days on antibacterial activity, pH, total acid, and total lactic acid bacteria. Antibacterial activity was evaluated using agar diffusion method. The results showed that the antibacterial activity, pH, and total of lactic acid bacteria of synbiotic green cincau drink decreased along the length of storage periode. Meanwhile, total of lactic acid increased. The results appeared that Salmonella sp. was the greatest inhibited by antibacterial agents in synbiotic green cincau drink. The lowest inhibition of synbiotic green cincau drink was found on Staphylococcus aureus. During the cold temperature storage, the synbiotic green cincau drink contained total of lactic acid bacteria ranged 9,54-10,12 (Log10) or equal 3,5x109-1,3x1010 CFU/ml, total of acid value 0.42% -0.87%, and pH 3, 80-4.10.
