Abstract

Abstract: Enhalus acoroides is a type of seagrass found in the waters surrounding the Morotai Islands but has not been economically exploited. Enhalus acoroides can be used to treat ulcers, acne medications, and cosmetics, among other things, due to their antibacterial activity against a variety of bacteria, one of which is Staphylococcus aureus . Staphylococcus aureus can cause respiratory and gastrointestinal tract infections. Staphylococcus aureus can infect any tissue in the body, causing damage to skin tissue. This study aimed to determine the antibacterial activity of E. acoroides against S. aureus and characterize the group of bioactive compounds found in the E. acoroides extract. This study took place between September and October of 2018. Enhalus acoroides samples were collected from the waters surrounding Morotai island. Extraction of E. acoroides in maceration using methanol and n-hexane solvents and qualitative identification of bioactive compounds including alkaloid compounds, flavonoids, steroids, and saponins. The results indicated that the yield of E. acoroides n-hexane extract was 0.35 percent and Methanol extract was 5.91 percent. Methanol extract E. acoroides (5.9 mm in diameter)1000 ppm is more antibacterial than n-hexane extract E. acoroides (5.6 mm in diameter). The Methanol extract of E. acoroides contains alkaloids, flavonoids, saponins, and steroids, whereas the n-hexane extract of E. acoroides contains steroids and flavonoids.
