---

Papaya (Carica papaya L.) is a plant which had been used by society since long time ago as a traditional medicine. It was predicted that there was antibacterial substances in papaya, so it can be used as antibiotic substitutes. The aims of this study were to know the extraction method and concentration of Carica papaya L. against the test bacteria. Carica papaya L. leaf extract were made by maceration method, grinding method, boiling fresh leaf method, and boiling dry leaf method. The test bacteria were E. coli and S. typhi. The inhibition zone was determined for concentration ranging from 10% to 100% (10%, 25%, 50%, 75%, 100%). Antibacterial activity test was done using paper disc and agar well methods. The result showed that Carica papaya L. leaf extract had antibacterial activities against E. coli and S. typhi that was showed by zone of inhibition. Maceration method with agar well was the most effective extraction method against of E. coli and S. typhi. The bigest zone of inhibition was showed in concentration 100%. The maceration method with agar well demonstrated the highest activity against E. coli (17±1 mm zone of inhibition) and S. typhi (15±0,5 mm zone of inhibition).

Keywords: antibacteria, Carica papaya L., Escherichia coli, Salmonella typhi.
