<![CDATA[Nanochloropsis sp. is the one of kind microalgae which is already cultivated in Indonesia. Nanochloropsis sp. contain of lipid which has potensial to product some biodiesel. In order that this research is acted to get an alternative fuel source which derivative from Nanochloropsis sp. The objective from this research are to explain effect of comparison mixture of solvent ; time of extraction; and also temperature to get the best result extract of lipid from Nannochloropsis sp. This research is acted with solid-liquid extraction methode which used mixture of solvent methanol and chloroform.The powder of Nannochloropsis sp. is extracted with various variable. The extract is then purified with destilation methode and analyzed used volumetric titration methode with NaOH 0,25N. The result indicate that the best way to get an optimum extract are mixed the solven, a comparison mixture of solvent methanol and chloroform which obtained optimum extract is 2:3 with time of extraction 3 hour and temperature 70°C.]]>
