Abstract

STUDY OF CULTIVATION AND LIPID EXTRACTION FROM MICROALGAE Botryococcus braunii USING MASERATION, SOXHLETATION, PERCOLATION, OSMOTIC AND AUTOCLAVE (Mega Silvia, 2016, 45 Pages, 10 Tabels, 18 Pictures, 4 Attachments) The potential of microalgae as a promising alternative raw material in the manufacture of biodiesel until now research is still being continued. This study uses a type of Botryococcus braunii microalgae with a focusses on the stage of cultivation and extraction of lipid, reminding both of the stages are of the most important and widely discussed in the research of biodiesel. Phase cultivation aims to study the growth phases of microalgae and the extraction step was to study the extraction of lipid from microalgae that produce the highest %yield of lipid through maceration, soxhletation, percolation, osmotic and autoclave methods. Based on the results obtained that the cultivation stage during cultivation, exponential phase occurred on the seventh day with the number of 5,208 x 104 cells/ml and from the extraction of lipid obtained that the highest %yield of lipid from soxhletation method with %yield of 8,5% and the lowest is the osmotic method with %yield of 0,8%. The volume of solvent n-hexane at soxhletation method which produces the highest lipid is in volume 175 ml with % yield of 24%. The results of GC-MS analysis on metyl ester showed that the methyl ester contains methyl palmitate, methyl oleate and methyl stearate as dominant fatty acid component
