Inhibitory Test Of Citronella Essential Oil (Cymbopogon Nardus L. Rendle) Againts Aspergillus Flavus Growth

Background: Indonesia is the one of tropical climate country with high air humidity. It becomes main factor fungal infection, that called otomycosis, which caused by Aspergillus flavus. The treatment otomycosis usually done giving an azole antifungal drugs can give beneficial and adverse effects. Treatment be various kinds herbs. One herbs used, it citronella. Citronella contains essential oil 0,4% in citronella citronellal 32-45% geraniol 12-15% has ability as antifungal. aim this study to determine inhibitory against flavus growth. Methods: type research laboratory experiments posttest only control group design. 24-hour used subjects had been inoculated on SDA media given oils concentrations 0.5%, 1.0%, 1.5%, 2.0 %. observation measuring diameter zone, uses a caliper. Results: from average growth zone each concentration, they are 0.5% ;1.0%; 1.5%; 2.0% 9.11 mm; 12.03 13.62 16.81 mm. higher concentration oil, makes wider inhibition zone. level sensitivity intermediate, sensitive, sensitive. effectiveness less effective, effective enough, very effective. results statistical analysis showed Conclusion: was have significanteffect
