UJI AKTIVITAS ANTIBAKTERI MINYAK ATSIRI RIMPANG BANGLE (Zingiber montanum) TERHADAP PERTUMBUHAN Streptococcus mutans

Abstract

Dental caries is a cavity condition that affects almost half of Indonesians caused by Streptococcus mutans. This research was conducted to determine the potential of bangle rhizome essential oil (Zingiber montanum) as an antibacterial against the growth of Streptococcus mutans. Tests are carried out using the diffusion method for the wells technique. In this study, eugenol was used as a positive control. Essential oil was diluted with acetone and obtained essential oil of bangle rhizome with a concentration of 3,12%, 6,25%, 12,5%, 25%, and 50%. The results showed that bangle rhizome essential oil succeeded in inhibiting the growth of Streptococcus mutans with the minimum inhibitory concentration 3,12% and with the optimal inhibitory concentration 50%.
