Pemanfaatan Ekstrak Rumput Laut (Eucheuma cottonii) Dari Perairan Sumenep Sebagai Antioksidan

Abstract

Seaweed is a plant that has the potential to be cultivated and has many benefits, one of which is as a natural antioxidant because it contains bioactive compounds that function to ward off free radicals. One of the seaweeds that has the potential to be developed is Eucheuma cottonii. This study aimed to analyze the proximate content, bioactive content and antioxidant activity of Eucheuma cottonii seaweed. This research was carried out in several stages, namely: seaweed preparation, proximate analysis, phytochemical analysis, and antioxidant activity tests carried out at the Marine Biotechnology Laboratory, Trunojoyo University Madura. The proximate content of Eucheuma cottonii seaweed is rich in water content in fresh form and rich in ash content in dry form, while the total fat content and protein content are very low. Bioactive compounds in Eucheuma cottonii seaweed are alkaloids, flavonoids, triterpenoids, and saponins. Eucheuma cottonii seaweed has the best antioxidant activity with methanol as a solvent with an IC50 of 757.05 ppm. The results of this study indicate that Eucheuma cottonii seaweed has the potential to be developed in the functional food sector.
