Abstract :
Evaluation of antimicrobial effectiveness of kacangma extract was carried out using disc diffusion test and direct inhibition test. Result showed that ethanol extracts at concentration of 50 and 100 mg/mL inhibited Staphylococcus aureus. Water extracts at concentration 10, 25, 50 and 100 mg/mL inhibited Aspergillus niger, 25, 50 and 100 mg/mL inhibited Saccharomyces cerevisae and at concentration 100 mg/mL inhibited Staphylococcus aureus. Heat treatments during direct inhibition test with incorporation of extracts did not show any differences of inhibitory effects against all microorganisms tested.
