However, information regarding their potential pharmaceutical uses remains largely unexplored. This study evaluates the antiproliferative activity of &lt;em&gt;Acanthophora spicifera&lt;/em&gt; collected from Indonesian extracted with different solvents of ethanol and methanol. &lt;strong&gt;Methods:&lt;/strong&gt; Cytotoxicity and antiproliferative activity of &lt;em&gt;A. spicifera&lt;/em&gt; crude ethanol extract (AS-EtOH) and &lt;em&gt;A. spicifera&lt;/em&gt; crude methanol extract (AM-MetOH) were evaluated with Lactate dehidrogenase (LDH) and Trypan blue exclusion assay in Human cervical cancer (HeLa) cells for 72h. Concentration of extracts treated in HeLa cells were 6.25 to 200 &lt;em&gt;μ&lt;/em&gt;g/mL. Viability staining with fluorescence stain Hoechst33342/PI was conducted to investigate apoptotic activity. Potential apoptotic activity of treatments was confirmed by DNA fragmentation assay. &lt;strong&gt;Results:&lt;/strong&gt; AS-MetOH demonstrated high cytotoxicity in HeLa cells with IC&lt;sub&gt;50&lt;/sub&gt; of 127.3 ± 33.13 &lt;em&gt;μ&lt;/em&gt;g/mL. However, AS-EtOH IC&lt;sub&gt;50&lt;/sub&gt; values could not be determined in this study. Antiproliferative activity was highly significant in AS-MetOH treated cells as cell density was suppressed to 20 x 10&lt;sup&gt;4&lt;/sup&gt; cells/mL compared to AS-EtOH (73 x 10&lt;sup&gt;4&lt;/sup&gt; cells/mL) and untreated cells (83 x 10&lt;sup&gt;4&lt;/sup&gt; cells/mL). Finally, apoptotic activity could be determined in AS-MetOH treated cells with increase PI fluorescence emitting cells and DNA fragmentation. On the other hand, apoptotic activity was not observable in AS-EtOH treated cells based on fluorescence viability staining and DNA fragmentation assay. &lt;strong&gt;Conclusion:&lt;/strong&gt; Current results show methanol solvent as an effective solvent to promote potential pharmaceutical properties of macroalgae &lt;em&gt;A. spicifera. &lt;/em&gt;Further advanced studies in a compound level from&lt;em&gt; A. spicifera&lt;/em&gt; methanol fraction would be reasonable for development of macroalgae based anticancer agent.&lt;/p&gt;
