Sponge cake created with 3 treatments, 100% wheat flour as control, 50% temulawak starch with 50% wheat flour and 100% temulawak starch, then execute organoleptic test. Preparation of temulawak starch flour produces yellowish white flour. The organoleptic test showed that sponge cake with substitution of temulawak starch was 50% and 100% preferred over sponge cake without starch flour of temulawak. Based on this research, it was found that temulawak starch flour potency as commodity source of food substitute of wheat flour in making sponge cake because it can substitute wheat flour to 100%.
