GUAVA (Psidium guajava L.) LEAF EXTRACTS CAN AS A GROWTH INHIBITOR Staphylococcus aureus

Abstract: Staphylococcus aureus is one of the bacteria found in the oral cavity. These bacteria are beneficial and play a role in normal physiological and defense development in humans, but in certain circumstances these bacteria can turn into pathogens due to predisposing factors, such as poor oral hygiene. One alternative used to maintain oral hygiene is guava leaf extract. Guava contains active compounds in the form of flavonoids, tannins, and alkaloids. Plants containing flavonoids have antibacterial activity, so guava leaves have the potential to inhibit the growth of Staphylococcus aureus bacteria in the oral cavity. The purpose of this study was to determine the potential inhibition zone contained in guava leaves against Staphylococcus aureus bacteria. This study used 4 concentrations, namely 25%, 50%, 75%, and 100% with each repetition 4 times. Guava leaf extraction was carried out by maceration method using 96% ethanol as solvent. Inhibition zone testing was carried out using the Kirby Baurer method.
