Antibacterial Activity Test of Tembelekan Leaf Extract (Lantana camara linn) against Edwardsiella tarda bacteria

The purpose of this study was to analyze the optimal dose Tembelekan leaf extract (Lantana camara Linn) which has antibacterial properties in inhibiting or killing Edwardsiella tarda bacteria. method used research is Completely Randomized Design (CRD). results yield obtained from tembelakan amounted 8.9%. positive phytochemical test contained active compounds, namely flavonoids, alkaloids, tannins, triterpenoids, and saponins. GC MS analysis tembelekan showed that most components were 4H-1-Benzopyran-4-one, 5,7-dihydroxy-6-methoxy-2-(4-methoxyphenyl)-,2,1,3-Benzothiadiazole, Benzisot hiadiazole , 3,4-Benzo-1,2,5-thia diazole. This compound a class isoflavonoids compounds. MIC (Minimum Inhibitory Concentration) lowest absorbance value at concentration 100 mg/L with 0.602 close control. Results discs doses 50, 100, 150, 200, 250 mg/L. disc 200 had strongest inhibition zone 12.63 mm. contains dominant compounds such as flavonoids alkaloids can be useful an inhibits growth E. bacteria
