Stick is one type of snack that is quite popular. The public's fondness for this stick makes it one of the most widely produced snack foods. The main raw material for stick making is wheat flour, where the import of wheat flour in Indonesia continues to increase. Therefore, the effort to reduce the need of wheat flour needs to be done, among others, by substituting wheat flour with local food products such as gadung flour from gadung tuber (Dioscorea hispida Dennst). Umbi gadung contains a high enough carbohydrate that is equal to 18%, for that gadung tuber potentially as a source of carbohydrates. However, on the other hand the gadung bulb contains HCN levels. To reduce the levels of HCN on the gadung tubers will be modified making of flour gadung using cabbage fermentation extract. The purpose of this research is to know the level of amylose, the hardness level and the sensori character and the best treatment stick with the substitution of gadung flour with variation of the addition of the flour of gadung as much as 0%, 10%, 20%, 30% and 40%. The result showed that there was no significant effect (p   0,05) on the substitution stick of the gadung flour. The best result of this research is stick with substitution of flour of gadung with the formulation of 10% flour of gadung with result of amylose content 58,47%, hardness 0,61N, sensory 3,20 (like) and HCN level 37,45 ppm. Top 10% gadung stick criteria are yellow-brown, fragrant aroma, crispy texture and savory taste.
