Abstract
Abstract Surfactant (surface active agent) has capability to decrease surface tension, interfacial tension and increase emulsion stability. Most of surfactant used in industry is produced from petroleum based. As petroleum is limited resources, the development of surfactant using renewable resources is more needed. Macro algae contain rich of polysaccharides such as agarose, carrageenans, and alginates. Some research has been done to study the production of new bio surfactant through the reaction of these polysaccharides with alcohol and lipid acid to promote high hydrophobic and hydrophilic site. This paper compared the production and the characterization of new biosurfactant, di-alkyl carbohydrate, from various macro algae such as brown algae (Sargasum sp), red algae (Euchema cottonii),and green algae. The main process was the extraction of polysaccharides at temperature of 80°C, followed by esterification. Result indicated that all surfactant produced could create oil in water emulsion system. Interfacial Tension tests were found in the range of 0,8 to 3,96 dyne/cm with surfactant concentration 1- 2,5% respectively. Fourier Transfer Infrared analysis has indicated that the product contain ester bond which lead to surfactant formation. Keywords: algae, surfactant, alkyl carbohydrate, interfacial tension
