Abstract

The concerns of antibiotic resistance have increased in recently years, this issue caused by long-term repeated use of antibiotics to treat bacterial illnesses. Lemongrass leaf (Cymbopogon citratus (DC.) Stapf) is one of the natural ingredients that can be used as an alternative antibacterial. The study objective is to determine the antibacterial activity of the ethanol extract of 70% cooking leaves against Staphylococcus epidermidis using diffusion methods. In addition, the Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) of extracts were determined using liquid dilution methods. The results of this study show that extract concentrations of 1,000,000 ppm have a barrier zone in the intermediate category when compared with the positive control, that is, clindamycin. Meanwhile, the MIC value obtained is 1250 ppm, while the MBC value is 5000 ppm. The results of statistical analysis showed that there were no significant differences in the inhibition zone diameter formed between the test concentrations.

Abstract

One of the plants had been used as a medicinal plant in Papua is Pometia Pinnata J.R Forst & G. Forst or the Matoa plant. The aim of this study is to determine the antibacterial activity of the active fraction of Matoa seeds against Escherichia coli bacteria. The positive control and negative control used were ciprofloxacin and dimethyl sulfoxide, respectively. 96% ethanol solvent was used to extract the simplicia of Matoa seeds. Fractionation was carried out using n-hexane, ethyl acetate and water as solvents. The Kirby Bauer diffusion method was used in the antibacterial activity assay at concentrations of 100 mg/mL, 200 mg/mL, 300 mg/mL, 400 mg/mL, and 500 mg/mL. Overall, the inhibition zones obtained from the sequential concentrations above were 8.89 mm, 10.18 mm, 10.34 mm, 10.84 mm, and 11.76 mm respectively. Further, data analysis was performed with One Way ANOVA and the results showed significant differences between concentrations. Data analysis was then continued with the post hoc Tukey HSD test and a concentration of 500 mg/mL was concluded as the optimum concentration.
