Phenolic content and flavonoids in<em> E. spinosum</em> can be obtained through a maceration process with methanol as a solvent which is generally carried out at room temperature. The extraction process to obtain maximum yield can be accelerated by increasing the extraction temperature. This research aims to determine the antioxidant activity of <em>E. spinosum</em> extracted using methanol at temperatures of 55, 65, and 75 °C. Before extraction, the seaweed was washed and dried in an oven at 40 °C for 24 hours. Extraction was carried out with 80 % methanol in a ratio of 1:10 (w/v). The parameters analyzed in this research were yield, phytochemical test, total phenolic content (TPC), total flavonoids, antioxidant activity including DPPH and FRAP. The data indicated that the extraction temperature affected total phenolic and antioxidant activity of both DPPH and FRAP, but did not affect the yield and total flavonoids. Extraction temperature of 55 °C had higher antioxidant activity with an IC<sub>50</sub> DPPH value 362.52±7.10 ppm and FRAP value 70.30±10.01 μM equivalent to Fe (II)/g.</p&gt;}, number={1}, journal={Jurnal Pengolahan Hasil Perikanan Indonesia}, author={Putu Tara HradayaKomala and Husni, Amir}, year={2021}, month={Apr.}, pages={1-10} }
