Abstract
Crude extract of Stichopus horrens's tissues that were collected from Bidong
Island, Terengganu were evaluated for their antibacterial, antibiofilm and antioxidant.
At the lower concentration of extraction from S. horrens 's tissue (0.234 mg/ml), the
sample showed negative value in percentage inhibition which is -13.797 %. This
indicate that the extraction of tissue from S. horrens do not possess antibiofilm
activity at lower concentration. When increasing the concentration of sample, the
percentage inhibitions also increase up to 49.456 %. However, the continued
increasing the concentration of sample, the percentage inhibition are started to
decrease to -15.544 %. There is no antibacterial activity detected in the S. horrens
which is indicating by no inhibition zones were measured against eight types of
bacteria tested. Only the controls which are ampicilin (gram-positive) and gentamycin
(gram-negative) show the inhibition zone in all the types of bacteria used.
