Abstract

Cinnamon stick (Cinnamomum burmanni) which contains antibacterial and able to cure acute respiratory tract infaction. The objective of this research is to investigate the antibacterial activities with days of maceration cinnamon stick which will produce the best obstruent against Staphylococcus aureus bacteria and Pseudomonas aeruginosa. The days of maceration are 3 days, 5 days, and 7 days. Then, choose the concentration of extract cinnamon stick based on MBC value which will be made to drink from extract cinnamon stick with the ratio of lemon juice : honey. Concentration of extract cinnamon stick are 1%, 2%, 3%, and 4%. Ratio of lemon juice : honey are 1:1, 1:2, 1:3, and 1:4. The antibacterial activities extract cinnamon stick, total phenolics, total flavonoids, sensory evaluation, and organoleptic were analyzed. This research showed that 7 days of maceration had ist strong obstruent antibacterial with MIC S. aureus 0,21±0,01% (w/v) and P. aeruginosa 0,26±0,01% (w/v) and MBC S. aureus 0,84±0,02% (w/v) and P. aeruginosa 1,04±0,02% (w/v). Formulation drink of extract cinnamon stick who had its obstruent antibacterial with strong concentration of extract 2% and ratio of lemon juice : honey 1:1
