The study aimed to analyze the effect of using some local tuber flour as alternative stabilizer on dragon fruit ice cream through physical and sensory quality. Tuber local utilizing was lombos (porang), meanwhile uwi, talas belitung, and CMC as a control. The research was conducted in three stages: 1) making of flours: lombos, porang, and talas belitung 2) making dragon fruit ice cream in addition of natural stabilizer of lombos flour, porang flour and talas belitung flour under various concentration levels at 0.1, 0.3 and 0.5% w / v and 3) determining of the best treatment from each natural stabilizer. The result showed that was red dragon fruit ice cream with 0.5% porang flour as stabilizer had similar effect to CMC as an ice cream stabilizer. The porang 0,5% treatment was overrun, 87,41% emulsion stability, melting time 95,45 minutes / 100 gram, 54,5 dPa.s viscosity, and 3.95 hedonic score (mildly like to like), 4.33 (like) hedonic texture and 4,53 (mildly gentle to soft) texture with scoring test.
