PEMANFAATAN ALGA COKLAT (SARGASSUM SP) MELALUI METODE KONVENSIONAL MENGHASILKAN NATRIUM ALGINAT
Abstract
One of the potential marine biota of Indonesian waters is a macro algae or known in seaweed trade. Makroalgaincludes red, green, and brown algae and is commonly referred to as seaweed. Brown seaweed has a pigment that givesbrown color and can produce algin or alginate, laminarin, cellulose, ficoidin and manitol whose composition is highlydependent on species, development period and place of growth The main component of algae is carbohydrate whileother components are protein, fat, ash (sodium and potassium) and water 80-90%. The purpose of this research is toknow the quality of alginate include alginate rendamen, moisture content, ash content, and viscosity. Conventionalextraction method from brown algae into sodium alginat produces the highest yield percentage of 36.63%, resultingfrom the extraction for 7 hours at 70°C Tthe average water content of 12.36 - 13.03%, the mean ash content of 26,13 -33.96%, and the viscosity ranged between 18,6 – 20,1 Cp.References
