However, its effect on ER- breast cancer cell lines had not been studied. Therefore, we want to examine the cytotoxicity effect of &lt;em&gt;K. pandurata &lt;/em&gt;Roxb. on ER- breast cancer cell line (MDA-MB-231). Nanoparticle is a form of preparation that optimizes the activity of any compound to the targeted cell. Therefore, it is expected that it can increase the effectivity of anticancer in &lt;em&gt;Kaempferia pandurata&lt;/em&gt; Roxb. In this study, the rhizome of &lt;em&gt;K. pandurata &lt;/em&gt;Roxb. trituration was dried and extracted with n-hexane solvent. Nanoparticle of &lt;em&gt;K. pandurata&lt;/em&gt; Roxb. was synthesized with CaCl&lt;sub&gt;2&lt;/sub&gt;, chitosan, and alginate by stirring with a magnetic stirrer, adjusting pH, and centrifugation. Then, nanoparticle was analized by UV/VIS spectrofotometry and transmission electron microscopy (TEM). The cytotoxicity of &lt;em&gt;K. pandurata&lt;/em&gt; Roxb. extract and nanoparticle were examined with MTT assay. The result of this test is data of inhibition percentage and IC&lt;sub&gt;50&lt;/sub&gt; value. The result showed that n-hexane extract of &lt;em&gt;K. pandurata &lt;/em&gt;Roxb. is synthesized into nanoparticle form with 99,43% yield percentage (entrapment value). Anticancer activity of n-hexane extract and nanoparticle of&lt;em&gt; K. pandurata&lt;/em&gt; Roxb. is moderate with IC&lt;sub&gt;50&lt;/sub&gt; value of the extract is 87,23 μg/ml and the nanoparticle is 24,23 μg/ml. The nanoparticle’s activity is better than the extract. n-Hexane extract and nanoparticle of &lt;em&gt;K. pandurata&lt;/em&gt; Roxb. has cytotoxicity effects towards MDA-MB-231 cell line. Nanoparticle can increase the cytotoxicity effect of &lt;em&gt;K. pandurata&lt;/em&gt; Roxb. extract because its hydrophobic feature and nanometer size.&lt;/p&gt;
