This  study  aimed  to  know  the physichochemical characteristic of  sodium  alginate  that was obtained from  Sargassum  crassifolium,  Sargassum polycystum,  Padina  sp.,  and  Sargassum  echinocarpum, which  grew  on  the  coral  coast  of  Gunung  Kidul  Yogyakarta  Indonesia.  The  result  showed  that  the average of the yield was 16.93 to 30.50%. The chemical properties, that is, water, ash, Pb and Hg were 12.50  to  13.43%,  18.20  to  8.59%,  0.083±0.01  to  0.36±0.04  ppm  and  0.002±0.01  to  0.3±0.05  ppm.  The physical properties such as viscosity and  lightness were 25  to 39 cps and 46.2  to 52.3  (the color was yellow to light brown). 

Key words: Sodium alginate, psychochemical, characteristic.
