The purposes of this research are; (1) to know the influence of kacang tunggak flour substitution towards the sensory quality of instant tiwul, (2) to know the content of protein and calcium in instant tiwul, and (3) to observe the level of likeness in the society towards instant tiwul with the kacang tunggak flour substitution. The object of this research is instant tiwul with the kacang tunggak flour substitution, by comparison of gaplek flour and kacang tunggak flour 90%:10%, 80%:20%, and 70%:30%. The method of data collection used subjective scoring for sensory and likeness tests. While the objective scoring was used to know the content of protein and calcium. The data analysis technique used in this research was Kruskal Wallis, Tukey test, descriptive analysis percentage and nutritional content test. The result shows that there is an influence of kacang tunggak flour substitution in the production of instant tiwul towards the quality of sensory in color, aroma, texture and stickiness. The likeness test shows the society responses towards instant tiwul of the kacang tunggak flour substitution 90%:10% with the presentation of likeness is 81.42%. The test of protein and calcium in control sample is protein 2.3% and calcium 64 mg, sample A protein 14.387% and calcium 353 mg, sample B protein 17.912% dan kalsium 364 mg dan sampel C protein 20.274% dan kalsium 397.4 mg.
