UJI AKTIVITAS ANTIBAKTERI EKSTRAK ETANOL DAUN KAYU MANIS (Cinnamomum burmannii blume) TERHADAP PERTUMBUHAN BAKTERI Porphyromonas gingivalis DENGAN METODE DISC DIFFUSION
Abstract
Periodontitis is the sixth highest disease worldwide with Porphyromonas gingivalis as
one of the causative bacteria. Cinnamon (Cinnamomum burmannii) leaves exhibit several
antimicrobial activities, such as antibacterial and anti-fungal. This study was conducted to
determine the antibacterial activity of Cinnamomum burmannii blume extract on the growth of
Porphyromonas gingivalis. The research design used was the post test only control group
design. Porphyromonas gingivalis bacteria grown on MHA media were treated using ethanol
extract of Cinnamomum burmannii blume with concentrations of 5%, 10%, 15%, 20% and
25%. The results showed that the ethanolic extract of Cinnamomum burmannii blume formed
an inhibitory zone around the paper disc on the growth of Porphyromonas gingivalis on MHA
media. So it can be concluded that in this study the ethanolic extract of Cinnamomum
burmannii blume showed antibacterial activity against the growth of Porphyromonas
gingivalis.
