Uji Daya Antibakteri Sari Akar Rumput Berisi Dalam Tanah (Lophatherum gracile) Asal Suku Anak Dalam pada Bakteri Penyebab Batuk (Streptococcus sp)

Abstract

Indonesia has a high biodiversity, both animals and plants. Indonesia also has ethnic/tribal diversity with different and unique traditional and cultural knowledge spread from Sabang to Merauke, one of which is the Anak Dalam Tribe. One of the plants found is Grass Filled in the Ground (Lophatherum gracile) which is used as a cough medicine. This plant contains chemical saponins, flavonoids, tannins, terpenoids, steroids and antibacterial. The purpose of this study was to analyze the antibacterial power of Grassroot Extract (Lophatherum gracile) from the Anak Dalam Tribe on Cough-causing Bacteria (Streptococcus sp). This type of research is empirical using tools and is based on a laboratory. This study is a descriptive analytic study that tested the root extract of Grass In Soil (Lophatherum gracile) on Streptococcus sp. The data analysis was carried out descriptively qualitatively by subtracting the diameter of the inhibition zone formed from the diameter of the disc that had been soaked with the extract of Lophatherum gracile. The treatments used consisted of 1 gram, 2 grams, 3 grams, 4 grams and positive control using amoxillin. Based on the test results, it was found that the inhibition zones formed were: 1 gram with an average of 0.6 mm, 2 grams with an average of 1.72 mm, 3 grams with an average of 2.57 mm, 4 grams with an average 2.92 mm and positive control with an average of 1.45 mm. Based on these results, the inhibition zone criteria are still in the "weak" category. This is due to the low concentration used in the test, so it is necessary to continue research to increase the concentration of root extract of Grass In Soil (Lophatherum gracile).
