Uji daya hambat ekstrak rimpang kunyit (Curcuma longa) terhadap pertumbuhan bakteri Staphylococcus aureus dan Pseudomonas sp.
Abstract
Abstract: Turmeric (Curcuma longa) is a plant that is known to have medicinal properties, especially the rhizome. The active compound that contained in the rhizomes are able to work as an antibacterial. This study aimed to measure the inhibitory of turmeric rhizome (Curcuma longa) extract against the growth of Staphylococcus aureus and Pseudomonas sp. This was an experimental laboratory study. The polar extract of turmeric rhizome (Curcuma longa) was tested by well method with concentration of 40%, 20%, 10%, and 5%. The result showed that the polar extract of turmeric rhizome (Curcuma longa) with a concentration of 40%, 20%, 10%, 5% can inhibit the growth of Staphylococcus aureus with the average of each is 15,0 mm, 14,5 mm, 13,5 mm and 11,0 mm while Pseudomonas sp with a mean diameter of each is 13,1 mm, 11,1 mm, 9,3 mm and 8,8 mm. Conclusion: The polar extract of turmeric rhizome (Curcuma longa) has an inhibitory effect against the growth of Staphylococcus aureus and Pseudomonas sp.
