Cassava is a staple food after rice and maize in Indonesia. In general, parts of cassava plants that consumed are the leaves and tubers. This research aimed to compare antioxidant activity of leaves and tuber from six types of cassava (Manihot utilissima Pohl). The leaves and tubers of the cassava plant from Cibinong were extracted with methanol separately. Methanol extract was measured the inhibition percentage as an antioxidant using DPPH reagent at 100 ppm. Results showed that Pucuk Biru leaves type has the highest inhibition at 88.09% and IC50 of 45.161 ppm.
