Seaweed of the genus Sargassum is generally a relatively large aquatic plant that grows and develops on firm substrate. Alginate is an essential compound widely required in various sectors, including food, non-food, and medical or pharmaceutical industries; however, the entire demand for alginate is currently met through imports. This study aims to characterize the quality of Sargassum polycystum as a raw material for alginate production based on the Indonesian National Standard (SNI) 2346:2015. The results showed that Sargassum polycystum had a sensory score of 8, moisture content of 12.75%, water absorption capacity (WAC) of 67.25%, and impurities content of 1.24%, meeting the Indonesian National Standard (SNI). Sargassum polycystum from Ujung Kulon has the potential to be used as a raw material for alginate production, with applications in nutraceutical, pharmaceutical, and various other industries.
