The research results showed that cassava farming was profitable in which income value was Rp15, 146,206.10/ha and R/C was 3.30. The production risk had a CV value of 0.057 and L 20.061; it meant that the production risk was low, because the result of CV <0.5 and L>1. The price risk had a CV value of 0.135 and L 644.695; it meant that the risk was low because the CV <0.5 and L>1. All cassava farmers behave neutral in facing the risk of cassava farming.
