Abstract

The lemongrass plants (Cymbopogon nardus) is one of the plants used as medicine such as strep throat, cough and colds. The purpose of this study was to determine whether the juice of fragrant lemongrass leaves has antibacterial activity against Streptococcus mutans bacteria that cause dental caries. The research method used is experimental with agar diffusion. The experiment consisted of four treatments namely at concentrations of 20%, 30%, 40% and 50% with three repetitions. The results showed fragrant lemongrass leaves at concentrations of 10%, 20%, 30% and 40% had an average inhibition zone diameter of 14,2 mm, 15,1 mm, 16,2 mm dan 17,3 mm. Fragrant lemongrass leaves can inhibit the growth of Streptococcus mutans.Keywords : Cymbopogon nardus, Antibacterial, Streptococcus mutans.

Abstract

Virgin Coconut Oil (VCO) has the ability as an antivirus, antibacterial and antifungal, it is due to the content of lauric acid, caprylic acid, Staphylococeus aureus and Enterococcus faecalis are bacteria that act as normal flora in the human body. If it exceeds a certain limit, both of these bacteria can become pathogens. The purpose of this study is to find out Virgin Coconut Oil from various brands can inhibit the growth of Staphylococcus aureus and Enterococcus faecalis.Antibacterial power test is done by the diffusion method to use the cylinder cup, and antibacterial power measured by the diameter of the urea inhibiting microbial growth by using a caliper. Antibacterial test results for Staphylococeus aureus bacteria on brand “A” (96.3 mm), brand “B” (10.3 mm), brand “C” (11 mm).The average brand “D” (8.6 mm), and in the bacteria Enterococcus faecalis in the brand “A” (3mm), brand “B” (6,1 mm), brand “C” (5.6 mm). Virgin Coconut Oil from various merck able to inhibit Staphylococeus aureus and Enterococcus faecalis bacteria.
