Nata de coco staining using carrot extract can give an attractive appearance. A more efficient staining method is the ultrasonication method. This study aimed to determine the effect of ultrasonication on physical and chemical characteristics of nata de coco with carrot (Daucus carota l.) as natural dye. The experiment was designed as a Factorial Completely Randomized Design (RALF) with two treatment factors and each treatment was repeated three times. The first factor was frequency (20 kHz and 40 kHz) and the second factor was duration of ultrasonication (15, 30, 45, and 60 minutes). The observed parameters on nata de coco colored with carrot extract were texture, color (lightness (L*), redness (a*), yellowness (b*) and total color difference (∆E*), pH, antioxidant and color after boiling. The result showed that frequency of ultrasonication had a significant effect on texture and pH of nata de coco colored with carrot extract; the duration of ultrasonication had a significant effect on lightness (L*) and antioxidant of nata de coco colored with carrot extract;. The A1B1 treatment (20 kHz, 15 minutes) was the best treatment based on the heighest value of an antioxidant activity which is 4631.72 ppm, with characteristics of texture 41.30 gf, lightness 52.97%, redness 4.83%, yellowness 5.43%, total color difference 66.33, and pH 3.80
