There were split in two kind of doses namely, preventive garlic;lemon 0,625% and turmeric;mengkudu 1,5%. The preventive treatment was given for two weeks before challenging test. The curative treatment was performed on one week after challenging test. Challenging test was carried out by intramuscularly injecting of 0,1 mL A. hydrophila (105cfu/ml) into the fish. The results of in vitro at doses of 5% of each extract showed antimicrobial. In the in vivo test, extracts of garlic and lime showed antimicrobial at a doses of 0.625%, while turmeric and mengkudu extracts effective inhibited in a doses of 1,5%.
