Corncobs are one of the agricultural wastes that have nutritional and functional content. The advantages of processing corn cobs into powder include durability, a smaller volume, and lighter weight, making it easier to pack and transport. One of the important steps in making corn cobs powder is drying to determine the durability and quality of the corn cobs powder. This study aimed to determine different drying durations of corncobs powders and their effect on physical, nutritional, and phytochemical properties as an alternative to functional food and foodstuffs. The experimental design used a Completely Randomized Design (CRD), consisting of one factor with four treatments: 4;5;6;7; and 8 hours and four replications. The results showed that different drying times had significant (p<0.05) physical, nutritional, and phytochemical properties. Corncobs powder with a drying duration of 7 hours has the best physical properties (water absorption at 1.34 ml/g, solubility at 26.76%, whiteness at 66.62%, and bulk density at 0.64 g/cm 3 ), nutritional contents
