Abstract

Abstract: About 30% of Staphylococcus aureus colonizes in the human body. This bacterium is one of the microorganisms that triggers various infectious diseases, including soft tissue and skin infections, endocarditis, osteomyelitis, bacteremia, and lethal pneumonia. One alternative that can be done is to utilize active substances that kill bacteria contained in medicinal plants. One of the plants that can be used as an alternative option is bay leaf (Syzygium polyanthum). The content of flavonoids, tannins, and essential oils in bay leaves (Syzygium polyanthum) is suspected to have antibacterial activity. The purpose of this research is to evaluate the antibacterial efficacy of bay leaf (Syzygium polyanthum) extract against Staphylococcus aureus at varying concentrations to determine its potential as a natural therapeutic agent. This study uses experimental research methods The technique used to measure antibacterial activity is disc diffusion. The results showed that bay leaf extract (Syzigium polyanthum) with concentrations of 10%, 30%, and 50% produced an average clear zone diameter of 14.83 mm, 20.00 mm, and 13.50 mm, respectively. Meanwhile, the diameter of the clear zone of chloramphenicol is 20.33 mm, and in aquadest, no clear zone is obtained. Bay leaf extract with a concentration of 30% had the highest clear zone in the treatment group.
