Method: The research was conducted in an experimental laboratory post test only control group design. Results : a sealer made from zinc oxide-eugenol had the largest diameter compared to the combination group of 100%, 75%, 50%, 25% tamarillo skin extract with sealer, and aquadest. Based on the One Way Anova test, there was a significant difference in the mean diameter of the inhibition zone (p <0.05) and the Post Hoc LSD analysis test showed that the sealer was the best group to kill the Enterococcus faecalis bacteria. Conclusion : sealers have a good effect on inhibiting Enterococcus faecalis bacteria as a cause of failure in endodontic treatment.
