Background: Indonesia has potential to be the biggest seaweed exporter in the world due to its fisheries potential. Brackish ponds are not merely used for cultivating fish and shrimp, but it is also used for seaweed cultivation. Thus, this study aimed to produce an innovative product that is staple food from Gracilaria Sp seaweed into analog rice, which can support pond formers in Sidoarjo.
Methods: Optimization of analog rice process from Gracilaria used Response Surface Methodology with various Gracilaria seaweed concentration (X1%) third levels (60%, 65%, 70%). However, parameter response that has been observed is iodine level (Y1 ppm), food fiber level (Y2%), yield (Y3%), aroma value (Y4), taste value (Y5), and texture level (Y6).
Results: According to the organoleptic test, analog rice from Gracilaria seaweed which composed of 65.84% seaweed, modified cassava flour 31.16%, and vegetable oil and glycerin 3% had optimum way of taste, aroma, and texture. Food fiber of seaweed composition (65%), modified cassava flour (32%), and vegetable oil as well as glycerin (3%) was 2.39% bigger than rice food fiber standard (1.3%). The iodine composition in the form of analog rice from Gracilaria seaweed was 74.55 ppm (74550μg) more than the average standard of human iodine needs of 150 μg/day.
Conclusion: Anolog rice made from Gracilaria Sp had good quality to consume.
