This study used a factorial randomized block design. The first factor is the proportion of Gracilaria verrucosa seaweed flour with white glutinous rice flour (P): (P1) 75%:25%, (P2) 50%:50%, and (P3)25%:75%, the second factor is concentration of CMC (K): (K1) 2%, (K2) 4%, and (K3) 6%. The data were analyzed using analysis of variance, followed by the BNJ test (Honest Significant Difference) at 5% level, and the organoleptic test was analyzed using the Friedman test. The best treatment was obtained in the P3K3 treatment (proportion of Gracilaria verrucosa seaweed flour with white glutinous rice flour 75%: 25% and CMC concentration 6%) with color L (lightness) 43.1; *a (redness) 4.9; *b (yellowness) 10.6; 1.66N texture; water content 37.40%; free fatty acid content of 0.28%; reducing sugar content 0.4%; and antioxidant activity 368.6 μg/ml.

Gracillaria verrucosa seaweed is one type of agar-producing red algae (agarophyte) that has the potential to be developed because it can be cultivated in polyculture in ponds together with shrimp and crab rearing.  Gracillaria verrucosa seaweed is usually used as a raw material for making gelatin, but it would be better to develop it in its processing so that it can produce products that have better economic value and nutritional value by utilizing Gracillaria verrucosa seaweed, and one of these preparations is dodol.  This study used factorial RAK (Randomized Block Design) which was repeated 3 times, with the first factor being the proportion of Gracilaria verrucosa seaweed flour with white glutinous rice flour (P) 75%: 25%, 50%: 50%, and 25%:  75%.  The second factor is the concentration of CMC (K) 2%, 4%, and 6%.  The data were analyzed using analysis of variance and then continued with the BNJ test (Honest Significant Difference) at 5% level. The best treatment was obtained in the P3K3 treatment (the proportion of Gracilaria verrucosa seaweed flour with white glutinous rice flour 75%: 25% and CMC concentration 6%) with  color profile L (lightness) 43.1;  color profile *a (redness) 4.9;  color profile *b (yellowness) 10.6;  1.66N texture water content 37.40%;  free fatty acid content of 0.28%;  reducing sugar content 0.4%;  antioxidant activity 368.6 g/ml.
