Iodine Fortification from Sargassum sp. on the Quality of Iodized Consumption Salt

Iodized consumption salt is salt intended for consumption purposes that has been enriched or fortified with Potassium Iodate (KIO3) to meet iodine requirements. One type of seaweed known for its high iodine content is dried Sargassum sp., which ranges from 0.2-0.5% in 2 grams. Samples of coarse salt, to be purified into pure salt, will be treated with 2N NaOH to increase NaCl content and fortified with Sargassum sp. iodine extract. This research method involves using iodine extract from Sargassum sp. as a compound to replace KIO3 in the process of iodizing consumption salt. The study aims to determine the optimum concentration of Sargassum sp. iodine for fortification in consumption salt according to SNI 3556:2016. The quality of iodized consumption salt is analyzed using parameters such as moisture content, NaCl content, insoluble matter content, iodine content, heavy metal contamination, and sample surface analysis. The results indicate that the best treatment to increase iodine content in consumption salt is P3 with the addition of 80 ppm Sargassum sp. iodine concentration and to ensure sustainable fisheries that are environmentally friendly.
