Currently, the renewable feedstock is the most needed worldwide. Microalgae are promising raw materials for supplying biofuels due to the depletion of fossil fuels. The microalgae found were mostly consists of freshwater algae. The aim of this research is to study the effect of different solvents and ratio using Soxhlet extraction method. Many parameters were introduced in this study in order to enhance the lipid production of microalgae. Lipid content of algae oil production known as Fatty acid that found was being analyzed. Different solvents used and ratio was expected to have different highest in lipid content. Chloroform, ethanol, and hexane were chosen as the solvents used. The best solvent for lipid production was the combination of different solvents and ratio. Data showed that 8% is the highest total oil extraction yield obtained from combination of chloroform and ethanol with a ratio (1:2). The compound and lipid content in algae oil are analyzed through Gas Chromatography Mass Spectrometer (GC-MS) analysis. Fatty acids have many benefits and also have interest preparation for health products. Green microalgae strain was being identified and cultured as future potential for biodiesel production. Significant of this study is to unveil the benefit of algae oil as sustainable future resources.
