Abstract. Kepok banana tuber flour is made from banana tuber and carried out various processes, namely separation from root fibers, chopping, soaking with a solution of whiting to prevent discoloration/browning, washing, draining, drying and sifting. Cookies are foods made from low protein flour, eggs, sugar, and butter. The purpose of this study was to determine the interaction and influence of differences in concentration and duration of soaking whiting solution on the quality of kepok banana tuber flour and to determine the best quality sensory cookies formulations.This research was conducted in 2 stages. The first stage was the manufacture of kepok banana tuber flour using a factorial Randomized Block Design with 2 replications. The first factor is the concentration of whiting solution (5, 10 and 15%) and the second factor is the soaking time (30, 60 and 120 minutes). Stage 2 is making cookies using a simple randomized block design , namely the comparison of the composition of low protein wheat flour and kepok banana tuber flour with 4 levels (100%: 0%, 85%: 15%, 70%: 30%, and 55%: 45%). The results showed that in step 1 the difference in the concentration of whiting solution had a significant effect on water content, ash content, fat content and protein content. While the immersion time significantly affects the level of brightness (L), water content, ash content, fat content. The best kepok banana tuber flour is F2T1 with a brightness level (L) of 71.4, water content 6.2%, ash content 6.7%, fat content 4.1%, protein content 3.2% and carbohydrates 79.9 %. In stage 2, the best formulation for cookies was P1 (15% banana kepok tuber flour: 85% wheat flour) with an organoleptic score of 8 (very attractive), aroma 7.3 (liked), taste 7.8 (very good) and texture 7.9 (very crunchy).
