Introduction: Jatropha curcas L. leaf extract can overcome periodontal disease because it contains compounds such as flavonoids, saponins, and tannins that are antibacterial. Objective: To determine the effectiveness and inhibition of Jatropha (Jatropha curcas L. ) leaf extract against Porphyromonas gingivalis bacteria. Materials and Methods: Paper discs placed on MHA media containing test bacteria, then ethanol extracts of jatropha leaves with concentrations of 20 %, 40 %, 60 %, and 80 %. Results: At a concentration of 20 % Jatropha curcas L leaf extract compared with a concentration of 40 %, 60 %, 80 % Jatropha curcas L leaf extract and negative control using distilled water had a p-value
