Comparison of The Effectiveness of Bandotan Leaves (Ageratum conyzoides Linnaeus) and Sintrong Leaves (Crassocephalum crepidioides) Extracts on The Growth of The Bacteri Staphylococcus aureus ATCC 6538

Abstract

Staphylococcus aureus is a leading cause of infections and infant mortality in Indonesia, especially pneumonia. According to data from the Indonesian Ministry of Health in 2022, pneumonia accounted for 14.4% of cases in infants and 9.4% in toddlers, with 1,475 cases reported in Cirebon city. Allergic reactions from antibiotics have become a serious issue in treatment, prompting the need for natural alternatives such as bandotan leaf (Ageratum conyzoides Linnaeus) and sintrong leaf (Crassocephalum crepidioides). The compounds alkaloids, flavonoids, saponins, and tannins present in these leaves are believed to effectively inhibit bacterial growth. The study aims to compare the effectiveness of bandotan leaf extract (Ageratum conyzoides Linnaeus) and sintrong leaf extract (Crassocephalum crepidioides) on the growth of Staphylococcus aureus bacteria. Experimental research with posttest-only control group design from April to July 2023. The study used 8 groups consisting of bandotan leaf extract (Ageratum conyzoides Linnaeus) and sintrong leaf extract (Crassocephalum crepidioides) at concentrations 50%, 75%, and 100%, as well as chloramphenicol (positive control) and DMSO 10% (negative control). Data were analyzed using One-way ANOVA, Post-hoc Tukey HSD, and Independent T-test. There is a comparison of the effectiveness of bandotan leaf extract (Ageratum conyzoides Linnaeus) and sintrong leaf extract (Crassocephalum crepidioides) against the growth of Staphylococcus aureus bacteria. Sintrong leaf extract (Crassocephalum crepidioides) exhibits an average inhibitory zone effectiveness of ± 10.44083 mm (P-value 0.000). The Crassocephalum crepidioides extract group was the most effective in inhibiting the growth of Staphylococcus aureus bacteria.
