Abstract

Marine fouling organisms cause severe problems in fishing nets, hulls, and power plant cooling systems. This study explores the potential of the active compound sponge Callyspongia pseudoreticulata as an environmentally friendly antibiofouling. This sponge was collected from the waters around Barrang Lompo, South Sulawesi. The sponge was extracted with various solvents (hexane, butanol, methanol, and water) using the maceration method. Barnacle Balanus amphitrite was taken from around the mouth of the Maros river and maintained in an aquarium at 25C. Test the antifouling activity of sponge extract using the 24 well polystyrene plates, Corning Cell Wells method. The observation was made after 48 hours, and the number of larvae that attached, died, metamorphosed, or did not settle was calculated under a microscope. Identification of chemical compound groups using phytochemical tests. The results showed that butanol extract has antifouling activity but is not toxic to Balamis amphitrite, with an EC50 value of 0.24 ug/mL, and other extracts do not show any antifouling activity. Phytochemical results show that butanol extract contains alkaloids, steroids, and terpenoids. From the results of this study, It can be concluded that Callyspongia pseudoreticulata can be developed as a new antibiofouling alternative source to replace tributyltin.
