The sponge is one of the sea organisms that has a prospect as a source of natural compounds including peptides, steroids, asetogenin, terpenoids, alkaloids, cyclic halide and nitrogen. This research was directed to obtain several species of sponges from the waters of Tasik Ria as well as testing the antibacterial activity of extracts from some of the sponge against the bacteria Escherichia coli and Staphylococcus aureus. From the identification, seven species of sponges were found, which consists of: Amphimedon sp., Axinosa sp., Aaptos sp., Theonella sp., Cribochalina sp., Hyrtios sp., and Lendenfeldia sp. The tests of antibacterial activity of the extracts from these sponges against test bacteria E. coli and S. aureus showed some positive results. Extract from Axinosa sp. sponge(16 mm) showed the strongest antibacterial activity on Escherichia coli bacteria. Followed by Hyrtios sp. extract (13.5 mm), Aaptos sp. extract (13 mm), Lendenfeldia sp. extract (13 mm) and Cribochalinai sp. extract(10.5 mm). While the the tests on Staphylococcus aureus bacteria showed that the strongest antibacterial activity was found from Axinosa sp. sponge extract (16.5 mm), followed by the extract from Aaptos sp. (15 mm), Lendenfeldia sp. extract (14.5 mm), Hyrtios sp. extract(13.5 mm) and Cribochalina sp. extract (11 mm).Keywords: Sponge, antibacterial, Escherichia coli, Staphylococcus aureus ABSTRAK Spons merupakan salah satu biota laut yang sangat prospektif sebagai sumber senyawa bahan-bahan alami antara lain peptide, terpenoid, steroid, asetogenin, alkaloid, halide siklik dan senyawa nitrogen.
