Tubers are source of high carbohydrate and can be used as an alternative to overcome food  insecurity in Indonesia. Processed tuber products generally are not developed well yet so the  products acceptance level are still low. This study was aimed to process sweet potato as  alternative source of non rice carbohydrate. The research used complete randomized design  with a number of panelists as replications. The treatments consisted of three (3) SPF  formulas, ie the concentration ratio sweet potato pasta, tapioca and wheat flour, namely: 1)  sweet potato paste : tapioca (70:30) 2) sweet potato pasta: tapioca: wheat flour (70:15 : 15),  and 3) sweet potato pasta: tapioca (80:20). Treatments were done on three (3) types of sweet
potatoes, they were white, red and purple sweet . Parameters of research were consumer  preferences on color (brightness), flavor, crispness and crispness in milk used hedonic scale  preference test with the 35 semi-trained panelists. The results showed that the level of  consumer preferences were not significantly different for all quality parameters on sweet  potato and red SPF and purple SPF except on white SPF. Comparison of sweet potato
pasta: tapioca at 70:30 on white SPF was more preferred on crispness and crispness in milk  parameters, with the level of preference were 1.5 (very crispy) and 1.0 (very crispy),  respectively. Meanwhile, the highest level of preference on the color and taste of SPF  obtained by formula II, respectively 1.0 (very bright) and 1.3 (very like).
