The study was conducted as a test to determine the effectiveness of Halimeda sp seaweed extract on the growth of some types of pathogenic bacteria. Seaweeds extracted consist of four (4) types which include: Halimeda macrophysa, Halimeda gracillis, Halimeda Opuntia and Halimeda renschi. While the types of pathogenic bacteria used were (Salmonella typhi, Staphylococcus aureus, Escherichia coli and Bacillus subtilis). This study uses methanol in the ratio of 1: 1 (v/v) and were observed for 48 hours. The test results showed that the extract of Halimeda sp is effective as antibacterial pathogen. Phytochemical test showed the presence of steroid and saponin compounds.
