One of the approaches for treating DM is by regulating the postprandial blood glucose via inhibition of &amp;alpha;-glucosidase enzymes. Seagrass is known as a plant containing bioactive compounds, especially for therapy antidiabetic. This research aims to evaluate the &amp;alpha;-glucosidase inhibition activity of three species seagrasses (&lt;em&gt;Enhalus acoroides, Thalassia hemprichii&lt;/em&gt; and &lt;em&gt;Cymodocea rotundata&lt;/em&gt;) from the Banten Bay, Indonesia. &lt;strong&gt;Methods:&lt;/strong&gt; The extracts of all parts (root, leaf, and stem) from three seagrasses were prepared with maceration method using 80% ethanol solvents. The &amp;alpha;-glucosidase inhibitory activity was conducted by microplate reader at 400 nm using acarbose as a positive control. Furthermore, the kinetics of &amp;alpha;-glucosidase inhibition, phytochemical screening, and total phenolics content were evaluated against extract which has the most potential &amp;alpha;-glucosidase inhibition. &lt;strong&gt;Results:&lt;/strong&gt; The result showed that the 80% ethanol extracts of &lt;em&gt;Enhalus acoroides&lt;/em&gt; (IC&lt;sub&gt;50&lt;/sub&gt; values 168.15 &amp;plusmn; 2.71 &lt;em&gt;&amp;mu;&lt;/em&gt;g/mL) had the most potential &amp;alpha;-glucosidase inhibitors activity compared with the positive control acarbose, &lt;em&gt;Thalassia hemprichii&lt;/em&gt; and &lt;em&gt;Cymodocea rotundata&lt;/em&gt; (IC&lt;sub&gt;50&lt;/sub&gt; values 197.27 &amp;plusmn; 3.07 &lt;em&gt;&amp;mu;&lt;/em&gt;g/mL, 425.86 &amp;plusmn; 5.15 &lt;em&gt;&amp;mu;&lt;/em&gt;g/mL and 429.28 &amp;plusmn; 8.89 &lt;em&gt;&amp;mu;&lt;/em&gt;g/mL). The kinetic type of inhibition against &amp;alpha;-glucosidase was noncompetitive inhibition. The phytochemical compounds were phenols, flavonoid, terpenes, and tannin with the total phenolic content was 28.76 &amp;plusmn; 2.46 mgGAE/g. &lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;Enhalus acoroides&lt;/em&gt; has the strongest inhibitor of &amp;alpha;-glucosidase and can be further developed for DM therapy agents.&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%">907</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Agung Widiyanto&lt;sup&gt;1&lt;/sup&gt;, Effionora Anwar&lt;sup&gt;1*&lt;/sup&gt;, Tati Nurhayat&lt;sup&gt;i2 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
