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;

Asch is one of the commonly found seagrasses spread over the coast of Indonesia and has not been utilized. Previous studies have reported its potency as an antioxidant, however, studies on optimal extraction conditions using ethanol as a solvent to obtain higher antioxidant activity are still limited. &lt;strong&gt;Objective:&lt;/strong&gt; The purpose of this study is to optimize the extraction condition for obtaining the highest antioxidant activity and total phenolic content of the seagrass &lt;em&gt;T. hemprichii&lt;/em&gt;. In an addition, percentage yield of extract was also evaluated. &lt;strong&gt;Methods:&lt;/strong&gt; In this study, factorial design with independent factors of ethanol concentrations (50%, 70%, and 100%), the use of HCl 1 N (Yes/No), and temperature (30&lt;sup&gt;0&lt;/sup&gt;C, 60&lt;sup&gt;0&lt;/sup&gt;C) was developed. The analysis of variance (ANOVA) was used to determine the significance of the above factors towards antioxidant activity and total phenolic content. The antioxidant activity was evaluated with 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the total phenolic content was determined by Folin-Ciocalteu method. &lt;strong&gt;Results:&lt;/strong&gt; The highest antioxidant activity (IC&lt;sub&gt;50&lt;/sub&gt;=83.48 &amp;mu;g/mL) was shown in sample R1 (extracted with 50% ethanol, added with HCl 1 N, and 60&lt;sup&gt;0&lt;/sup&gt;C). The sample was also showed total phenolic content 41.03 mg GAE per gram and 22% yield extract. Among the factors examined, the used of HCl 1 N showed the most significant effect to the antioxidant activity and the total phenolic content, with the &lt;em&gt;p&lt;/em&gt;-value of 0.048 and 0.034 respectively (&lt;em&gt;p&lt;/em&gt;&amp;lt;0.05). &lt;strong&gt;Conclusion:&lt;/strong&gt; This extraction condition can be applied to obtain higher antioxidant activity and total phenolic content from the plant.&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%">958</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Nely Suryani Nopi&lt;sup&gt;1&lt;/sup&gt;, Effionora Anwar&lt;sup&gt;1*&lt;/sup&gt;, Tati Nurhayati&lt;sup&gt;2 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
