Antibacterial Activity of Pineapple Infused Arak Bali Against Escherichia coli

Abstract

Arak Bali is one of the gastronomic drinks that has the potential to be developed to attract tourists. The use of pineapple as an infusion ingredient in Arak Bali has been proven to be able to increase the type and concentration of bioactive compounds in Pineapple Infused Arak Bali.  The bioactive compounds play an important role in the bioactivity of Pineapple Infused Arak Bali, one of which is an antibacterial activity. This research is a true experimental type with a Post-test Only Control Group Design. The purpose of this study was to determine the antibacterial activity of Pineapple Infused Arak Bali (FU and FD formulas) against Escherichia coli. The antibacterial activity was determined by dilution and diffusion method to find out the Minimum Inhibitory Concentration (MIC) and the antibacterial activity. The results showed that Pineapple Infused Arak Bali had an antibacterial activity with MIC at a concentration of 60%, whereas in Arak Bali no MIC was found. The results of this study prove that Pineapple Infused Arak Bali has better antibacterial activity against Escherichia coli than the original formula, Arak Bali.
