Cassava starch is one of potential biopolymer resources that easily grow in Indonesia. Starch processing should be done before the starch utilized in food, adhesive, medicine, and bioethanol industries. Nowadays, the developments of starch processing are performed using high-intensity energy treatment such as, high shear mixing and sonication. In this work, the sequential combination of HSM and sonication was employed to obtain better structural degradation. From the result, HSM increase the swelling capacity of cassava starch, then sonication successfully produce massive granule macro-structure degradation. Decrease of total carbohydrate content was observed throught both HSM and Sonication process. It also found that HSM only attacked relatively low-molecular weight of the granule part. Otherwise, the further processing with sonication resulted in significant reduce of carbohydrate chain length.
