Then, the macroalgae extracts are diluted into 8 different concentrations. Afterwards,&lt;em&gt; in vitro&lt;/em&gt; anticancer activity evaluation of hexane, ethyl acetate, chloroform and ethanol extracts of &lt;em&gt;G. verrucosa&lt;/em&gt; against cervical HeLa cells were conducted by MTT cell proliferation assay. Triplo mechanism is also applied in this study to increase the accuracy of the results. The anticancer activity is measured using IC&lt;sub&gt;50&lt;/sub&gt; value. &lt;strong&gt;Results:&lt;/strong&gt; The four concentrated extracts &lt;em&gt;G. verrucosa &lt;/em&gt;showed cytotoxicity against cervical HeLa cells. The greatest anticancer activity is depicted by hexane extract with an IC&lt;sub&gt;50&lt;/sub&gt; of 14.94 &amp;mu;g/mL, followed by chloroform (IC&lt;sub&gt;50&lt;/sub&gt; 15.74 &amp;mu;g/mL), ethyl acetate (IC&lt;sub&gt;50&lt;/sub&gt; 16.18 &amp;mu;g/mL), and ethanol (IC&lt;sub&gt;50&lt;/sub&gt; 19.43 &amp;mu;g/mL). &lt;strong&gt;Conclusion:&lt;/strong&gt; Our results clearly indicate that hexane, ethanol, chloroform, and ethyl acetate extracts of seaweed &lt;em&gt;G. verrucosa&lt;/em&gt; can be further developed to be anti-cervical cancer agents, with hexane extract displaying the greatest cytotoxic effect.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">1007</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Micheylla Kusumaning Dewi&lt;sup&gt;1&lt;/sup&gt;, Ade Arsianti&lt;sup&gt;2,3*&lt;/sup&gt;, Cut Raisya Zahira Zagloel&lt;sup&gt;1&lt;/sup&gt;, Yully Astika Nugrahayning Aziza&lt;sup&gt;1&lt;/sup&gt;, Kartika Dwi Kurniasari&lt;sup&gt;1&lt;/sup&gt;, Baiq Kirana Dyahningrum Mandasari&lt;sup&gt;1&lt;/sup&gt;, Riathul Masita&lt;sup&gt;1&lt;/sup&gt;, Futihati Ruhama Zulfa&lt;sup&gt;1&lt;/sup&gt;, Norma Nur Azizah&lt;sup&gt;3&lt;/sup&gt;, Rista Putrianingsih&lt;sup&gt;2&lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
