ANTIMIKROBIAL ARIEN (HYPNEA CERVICORNIS) ASAL GILI KONDO TERHADAP BACILLUS SUBTILIS, STAPHYLOCOCCUS AUREUS & ESCHERICHIA COLI

ABSTRAK: To determine the bioactivity of the species Hypnea cervicornis J.Agardh a test was carried out by using crude extract and their fractions against a number of bioindicators like Bacillus subtilis, Staphylococcus aureus and Escherichia coli.  The bioactivity of H. cervicornis was tested using Kirby-Bauer Method.  The test showed that both the crude extracts as well as the fractions, on crude extract concentration 45 % - 55 %,  methanol fraction concentration 2,5 % - 12,5 % and n-hexane fraction concentration 1,25 % - 6,25 %, biologically active against the organisms used as bioindicators. As these extract and fractions of H. cervicornis with its bioactivity could open the opportunity for the use of H. cervicornis as an antibacterial bioactive agents.
