Test the Effectiveness of Dayak Leeks (E. Palmifolia) Using Ethyl Acetate Solvent Against Staphylococcus Aureus Growth By the Well Method

Abstract

Dayak leek (Eleutherine palmifolia) is one of the plants that is often used by people for traditional
medicine in the Kalimantan region. Based on research, Dayak leeks contain alkaloids, flavonoids, saponins
and tannins which can function as antibiotics.
The aim of this research is to determine the effectiveness of Dayak leeks (Eleutherine palmifolia) using
ethyl acetate solvent on the growth of Staphylococcus aureus using the well method. The research design used
was true experimental, where this study used a treatment group and a positive control group (clindamycin 2
mcg).
The results of the research showed that in the test Dayak leek extract with concentrations of 60%,
65%, 70%, 75% and 80% formed an average diameter of the inhibition zone of 2 mm, 3.8 mm, 4 mm, 4.4 mm
and 7 mm in a row. And the control material clindamycin 2 mcg obtained an inhibition zone of 14 mm. So it
can be concluded that Dayak leeks can be used as an alternative to antibiotics, especially at high
concentrations.
