RASIO NATRIUM KARBONAT DALAM EKSTRAKSI BERPENGARUH PADA MUTU NATRIUM ALGINAT Sargassum muticum

Abstract

Several studies have been conducted in an effort to improve alginate extraction efficiency. This study aims to determine the effect of Na2CO3 ratio on the quality of sodium alginate Sargassum muticum. The Na2CO3 ratios used were 1:10, 1:20, 1:30, 1:40, 1:50 (w/v) and quality analysis were made on yield (%), viscosity (cps), pH, moisture content (% ), white degree (%), ash content (%) and functional group. The results showed that the higher Na2CO3 ratio had significantly lower viscosity. The value of yield, pH, moisture content, degree of white, and ash content showed that the effect of Na2CO3 ratio did not significantly different. The best Na2CO3 ratio was 1:20 w/v because it had medium viscosity, besides that, as a result of yield, pH, moisture content, white degree, ash content has met alginate quality standards.
