THE POTENTIAL OF RED GINGER EXTRACT (ZINGIBER OFFICINALE VAR RUBRUM) AGAINST STAPHYLOCOCCUS AUREUS AND STAPHYLOCOCCUS EPIDERMIS

Abstract

Red ginger (Zingiber Officinale Var Rubrum Rhizoma) is a plant that is often found in Indonesia. Local people often use rhizomes to treat various diseases such as antibacterial, antioxidant, anti-inflammatory, analgesic, diuretic, antifungal, anticancer, and antiviral. This study aims to determine the antibacterial activity of red ginger extract against the bacteria Staphylococcus aureus and Staphylococcus epidermis. This research method was carried out through the stages of maceration, extraction, and testing the antibacterial activity of red ginger extract using the disc method using concentrations of 25,000ppm, 50,000ppm, and 100,000ppm. The results of the antibacterial activity test were obtained in testing the bacteria Staphylococcus epidermis, there was an inhibition zone at a concentration of 25,000ppm of 70 mm, 50,000ppm of 75 mm, and 100,000ppm of 95 mm, while in the test for Staphylococcus aureus, there was an inhibition zone at a concentration of 25,000ppm of 60 mm. 80,000ppm by 75 mm, and 100,000ppm by 95 mm. This study concludes that in testing Staphylococcus epidermis, the inhibitory power is very strong at a concentration of 100,000 ppm, as well as in Staphylococcus aureus bacteria.
