Abstract
Sargassum siliquosum is brown seaweed, containing alginate required by various industries that are currently imported. The
aim of the study is to determine the optimum concentration of the chemical in alginate extraction. The study design using
Central Composite Design to see the response of surface method used to see the effect of the treatment for maximum yield of
alginate. The results showed that the optimum concentration of the chemicals to extract alginate are Na2CO3 14.2 %; CaCl2 14.1 %; and HCl 3.5 %. In these conditions, the yield of alginate was 26 g / 100 g. Verify the optimum conditions yielding
26.18 g / 100 g. Characteristics of alginate product was 3.7 % moisture content, ash content 18.43 %, cP viscosity 16.5 and
pH 6. Metal content: As <0.01 ppm; Pb 23.43 ppm and Hg 0.054 ppm.
