Abstract: This study aims to determine the effect of turmeric extract with macerated a distilled water solvents in inhibiting the growth of Aspergillus parasiticus, and maintaining the nutrient content of corn in some storage time. This study consisted of 2 stages: stage I (the minimum concentration of extract test which still showed inhibitory ability and as an antifungal against Aspergillus parasiticus), stage II (the best potential concentration of turmeric extract from stage I as antifungal against Aspergillus parasiticus and the ability to maintaining nutrients and fungal /mold content and total aflatoxin in corn for a period of time in storage, Stage I experiments of turmeric extract compared to several levels of concentration (K1 = 25% K2 = 50%, K3 = 75%, K4 = 100%). Stage II the best concentration of turmeric extract from the first stage compared to the second factor: storage time (L1 = 0 days, L2 = 7 days, L3 = 14 day, L4 = 21 days, L5 = 28 days). Variables observed are inhibitory ability, antifungal activity, moisture, crude protein content, gross energy, % corn contaminated with fungal/mold, % contaminated aflatoxin, and totally contaminated with aflatoxin on a quantitatively. The results showed that the minimum concentration of turmeric extract has inhibitory ability is at a concentration of 25% and the best antifungal activity at the concentration of 100%. The extract turmeric gives significant effect (P <0.01) on the ability to maintain the nutritional content of corn and inhibit the growth of fungi/mold and aflatoxin both qualitatively and quantitatively for 28 days of corn storage. From the results of this study it can be concluded that the addition of turmeric extract, at a concentration of 100% can inhibit fungal/mold growth and aflatoxin in corn and also can maintain the nutritional content of corn for 28 days of storage.
