Abstract

Many cases of Staphylococcus aureus bacterial infections are difficult to treat due to resistance to Methicillin (MRSA). Kuswiyanto (2019) states that MRSA infection therapy can be developed using natural ingredients, one of which is dewandaru (Eugenia uniflora L). The leaves of this plant are proven to have antibacterial activity against gram-positive and negative bacteria (Wahyudin et al., 2017), due to the presence of flavonoid and saponin compounds (Onwudiwe, et al, 2010; Shah and Seth (2010)). This study aims to determine the antibacterial activity of dewandaru (Eugenia uniflora L) leaf extract against Staphylococcus aureus bacteria. This experimental study used a Prottest Only Control Group Design. Dewandaru leaves were extracted by maceration method and made concentrations of 100%, 75%, 50%, 25%, and 10%, using sterile aquadest. Activity test using Mueller Hinton Agar media with the well method. Positive control used chloramphenicol, and negative control used sterile aquadest. The activity test results showed that all concentrations of dewandaru leaf extract produced inhibition zones around the wells with diameters of the sequence are 23.6mm, 21.6mm, 20.6mm, 19mm and 15.6mm. Based on these results it can be concluded that the extract of dewandaru (Eugenia uniflora L) leaves has antimicrobial activity against Staphylococcus aureus bacteria which is characterized by the presence of a clear zone on Mueller Hinton Agar media.
