USE OF TARO BOGOR ( Colocasia esculenta ( l.) Schott ) AS A GROWTH MEDIUM FOR Aspergillus flavus

Fungi are one type of microbe that plays an important role in human life, there are many groups of fungi that can be found in everyday life, one type of fungus that is pathogenic and produces aflatoxins, namely fungi with Aspergillus flavus species. Bogor taro has the potential to be used as a raw material because it has a carbohydrate content of 23.7% as an energy source, while potatoes have a total carbohydrate of 19.10%. So it can be known that the amount of carbohydrates in taro bogor is more than potatoes. Based on this background, researchers are interested in conducting research related to the use of taro bogor ( Colocasia esculenta ( L.) Schott ) as a growth medium for the fungus Aspergillus flavus. This type of research is experimental with Posttest Only Control Group Design research design, in this study the control group in the form of Aspergillus flavus planted on PDA medium while in the experimental group in the form of Aspergillus flavus planted on taro medium at a concentration of 2%. 4% and 6%. Conclusion based on the results of the paired T-test test, the p-value of taro medium is 2% and 4% less than 0.05 which means there is a significant difference with PDA medium, while in taro medium 6% the p-value of > 0.05 which can be concluded that there is no significant difference between taro medium 6% and PDA medium.
