Process for Obtaining Green Algae Oil As A Resource Development Effort Alternative Raw Materials on Biodiesel Production Process

Abstract

Microalgae have received much attention as a renewable energy source. Microalgae have high potentials in biodiesel production compared to other oils crops. First, the cultivation of microalgae does not need great areas as compared to that of Terraneous plants. Biodiesel produced from microalgae will not compromise the production of food and other products derived from crops. Second, microalgae grow extremely rapidly and many algal species are rich in oil. Because of the reasons they reason, we used Green Algae as microalgae in this experiment. The osmotic method was chosen because microalgae are multispecies and a multi-cell microorganism with the semipermeable membrane, which is delicate in osmotic pressure shock. Green Algae can grow well in 20 - 40°C in slightly alkaline solution and highlight intensity roommates are suitable in Indonesia's weather. Acid chloride as a solvent was chosen because of their highest osmotic pressure effect due to their semipermeable membrane. Also, percolation method used as the reference method, this method is usually adopted in pharmacy industries to recover volatile oils. 77.236% - weight of algae oils in this study was extracted using ethanol as a solvent. The percentage of oil by ethanol was bigger than to the HCl-osmotic method, only 71.218% - the weight of oil was extracted by the osmotic method. With increasing the number of solvents, the time of mixing and the higher molarity of the solution will be the rise of algae oil. The yield of algae oil by hydroalcoholic phase and operation time. 37.63% water in hydroalcoholic phase Contain give 76.584% the weight of oil. The solvent types are used also roommates influence the algae oil composition, especially the composition of the FA, MG, DG, and TG and pigment compounds in the oil.
