In Indonesia, cassava (Manihotesculenta Crantz) and sweet potatoes (Ipomoea batatas Lam) tubers are used as a
source of energy and leaves as a source of vitamins and minerals for both humans and livestock. The crop is
gradually being transformed from a famine reserve crop and rural staple food to a cash crop for urban consumption.
In 2012, production, harvested area, and the level of productivity of cassava and sweet potato in Indonesia reached
24.18 ton/year, 1.13 million ha, 214.02 Ku/Ha and 2.48 ton, 178 thousand ha, 139.29 Ku/Ha [1]. Traditional
utilization of cassava and sweet potatoes, in Indonesia, was limited to roasting and boiling of fresh roots for
consumption. However, it was reported that tubers are also processed into flour [2].
