<![CDATA[Abstract Chlorella sp. is green microalgae thatcontain bioactive compounds which can be used as biological functions.This chlorella was obtained from a sea of Bagansiapiapi waters. The purpose of this study was to obtain the best yield value of Chlorella sp.extractedwith a different solvent. The experimental research method consisted of 3 stages, namely: 1) sample preparation, 2) sample extraction with different solvents, 3) yield testing. The design used was a non-factorial Completely Randomized Design (CRD) with 4 treatment levels using different solvents: n-hexane (N1), ethyl acetate (N2), methanol (N3) and aquades (N4) with 3 replications, so obtained 12 experimental units. The results showed that the Chlorella sp. was extracted withn-hexane solvent (N1) was the best treatment containing the highest yield ofChlorella sp.(51.17%), followed by methanol solvent (50.76%), aquades (34.71%) and ethyl acetate (26.09%). Therefore, n-hexane is more effectively usedto extract Chlorella sp.Key words: Chlorella sp, Different solvents, Yield]]>
