Staphylococcus aureus is a nosocomial problem that can cause skin infections. Treatment of skin infections can be done by using citronella (Cymbopogon nardus) which is antibacterial because it contains compounds such as flavonoids, steroids, terpenoids, saponins, and essential oils. This study aims to determine the antibacterial power of Cymbopogon nardus leaf starch essence against Staphylococcus aureus inhibition zone. This type of research is a laboratory experiment using a post-test only control group design. The results showed that the extract of Cymbopogon nardus leaves with a concentration of 5%, 10%, 15%, and 20% with positive control of ampicillin had different inhibitory zona against Staphylococcus aureus bacteria. The conclusion is that the concentration of Cymbopogon nardus leaf starch is the most effective and forms an inhibition zone with the largest average (16.28), namely a concentration of 20%.Keywords: Antibacterial, lemongrass, Staphylococcus aureus

Aloe vera (Aloe barbadensis Miller) contains anthraquinone compounds, flavonoids and saponins which are thought to have antibacterial effects so as to inhibit bacterial growth. The purpose of the study was to determine the inhibitory power of Aloe barbadensis Miller on the growth of Staphylococcus aureus bacteria. The pure experimental study was conducted with The Randomized Posttest Only Control Group Design using six (6) treatments, namely aloe vera extract with a concentration of 25%, 50%, 75%, 100%, Chloramphenicol 30 mcg antibiotics as a positive control, and sterile aquadest as a control negative for Staphylococcus aureus bacteria grown on Mueller Hinton media. After being treated, it was incubated for 24 hours and measured its inhibitory power. The growth inhibition data of Staphylococcus aureus bacteria in the form of inhibition zone diameter was analyzed statistically by Kruskal Wallis test, at the level of confidence α = 0.05. The results showed that the average inhibitory effect of Aloe vera extract on the growth of Staphylococcus aureus bacteria in concentrations of 25%, 50%, 75% and 100% were 0 ± 0 mm; 7.125 ± 0.1250 mm; 8.375 ± 0.23936 mm; and 9.0 ± 0.40825 mm. Based on the results of the study concluded that aloe vera extract can inhibit the growth of Staphylococcus aureus bacteria. The higher the concentration of Aloe vera extract the greater the inhibitory effect on the growth of Staphylococcus aureus bacteria.

Eye Pain

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of ​​inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values ​​<0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.
