PRODUKSI DAN ANALISIS AGAROSA DARI RUMPUT LAUT JENIS Gracilaria sp. ASAL KABUPETEN TAKALAR

Abstract

Has been done attempt production and analisis of agarose from seaweed Gracilaria sp. of Takalar Regency, with aim to produce agarose and analysis physicochemical properties such as viscosity, yield value, and characterized fungsional groups of agarose with Spectra Infra Red (IR). The result attempt showed that 10 gram of seaweed Gracilaria sp. yield 1,434 gram agarose, and if agarose in colloid solution 1% at 80^oC had the viscosity 15,2 cP and the yield value 0,039 dyne cm^-, while IR spectra obtained the hydroxyl group (OH) with hydrogen bonding in the region 3455.10 cm^-1, the hydrocarbon group (C-H) in the region 1455.77 cm^-1 and the  ethers group (C-O) in the region 1077.32 cm^-1. Which the result could be compared with the standart agarose.
