Characteristics of Gelidium sp seaweed and its agar from Lampung Waters

Abstract

Research on the characteristics of seaweed Gelidium sp from Lampung waters and its agar has been done. This study aims to look at the characteristics of Gelidium sp seaweed harvested by seaweed collectors and its agar produced. Seaweed is wild harvested from the main Gelidium producing area in Lampung, Krui. The seaweed quality parameters observed were moisture content, impurities and clean anhydrous weed (CAW) as well as the agar yield. While the parameters of agar quality were moisture content, gel strength, gelling point and melting point. The results showed that Gelidium sp has an average of moisture content 15.53%, impurites 20.80%, CAW 38.13% and agar yield 8,21%. The results of agar quality observations showed moisture content of 10.15%, gel strength of 674 g/cm2, gelling point 31.50C and melting point 800C. These results indicate that Gelidium sp is potentially used as a raw material for agar extraction.
