The design used in this study was a completely randomized design (CRD) with the treatment of the ratio of wheat flour and cilembu sweet potato flour (100%:0%, 90%:10%, 80%:20%, 70%:30%, 60%: 40%, 50%:50%). Parameters observed in this study included water content, ash content, fat content, protein content, carbohydrate content, crude fiber content, swelling power and sensory assessment including color, taste, aroma and overall acceptance. The data obtained were analyzed by the analysis of variance and if there was an effect of treatment on the observed parameters, then it was continued with the Duncan Multiple Range Test (DMRT). The ratio of 60% wheat flour with 40% cilembu sweet potato flour produced the best putu ayu cake with the characteristics: water content 44.99%, ash content 0.72%, protein content 6.42%, fat content 23.02%, carbohydrates 24.83 %, crude fiber content 5.95%, swellability 22.66%, and had sensory properties with overall acceptance criteria “like”.]]>
