There are 2 factors in this research, first factor with 4 levels is the addition of red dragon fruit skin (0%;15%;20%;25%) and the second factor with 3 level is the addition of different types of sugar (sucrose, corn sugar, sucrose:corn sugar). The result of this research showed that there was an interaction between the addition of red dragon fruit skin and the type of sugar to the water content, sugar reduction, texture analysis, redness level and organoleptic (taste, texture and level of contentment). The best treatmen is K2G1 (20% red dragon fruit skin and sucrose) with water content 26,41%, ash content 0,53%, pH value 4,62, texture analysis 35,89 N, total anthocyanin-betasianin 1,09 mg/L, antioxidant activity 44,76%, sugar reduction 4,44%, brightness (L) 37,20, redness level (a+) 10,53, total calories 438 kkal and 112,36 g carbohydrates, flavor 3,0 (quiet like), taste 3,37 (tasty), texture 3,70 (quiet chewy) dan level of contentment 3,57 (quiet like).
