Abstract

Sponge organisms produce bioactive compounds that are toxic as a means of self-defense. The compound is known to have the potential as an antibacterial and anti-UV which can absorb sunlight with the potential to be used as a material for making sunscreen. The purpose of this study was to obtain antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria and anti-UV activity from crude extracts and sponges fractions. The antibacterial test done by agar diffusion method (Kirby and Bauer diffusion disc) and the crude extract and the active fraction of antibacterial compounds were tested in a UV spectrophotometer to see its anti-UV activity. As a result, 4 species of sponges were extracted and partitioned into water fractions, methanol fractions, and n-hexane fractions. All samples were tested for antibacterial activity and the results showed antibacterial activity against S. aureus by Plakortis sp. in crude extract (9 mm) and water fraction (8.6 mm), Agelas sp. in crude extract (7 mm) and in E. coli bacteria shown by Plakortis sp. in crude extract (12.6 mm) and water fraction (9 mm), Liosina sp. in the water fraction (7.6 mm), Haliclona sp. in the water fraction (8 mm) and Agelassp. in crude extract (10.3 mm). Crude extracts and water fractions were tested using a UV spectrophotometer for anti-UV testing, the results showed that crude extract and all the water fractions of four species sponge could absorb UV-B (λ 290-320 nm) and UV-A (λ 320-400 nm).Keywords: sponges, antibacterial, partition, anti-UV

Abstract

Ascidians are sesile marine invertebrates that have bioactive compounds such as antibacterial and anti-UV. The purpose of this study is to determine the antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria and to test the anti-UV activity of the ascidian water fraction. Antibacterial activity test was carried out using the diffusion method (disc diffusion Kirby & Bauer) and the water fraction of ascidian that showing antibacterial activity tested in a UV spectrophotometer to see the anti-UV activity. Results of the study were obtained 4 types of ascidians extracted from partitioned into water fraction, n-hexane fraction, methanol fraction. All three fractions were tested for antibacterial activity and the result showed that there were antibacterial activities of ascidian extract Clavelina sp. against both test bacteria with inhibition of S. aureus and E. coli with strong categories. Ascidian Phlebobranch sp. showed the presence of antibacterial activity with inhibition of S. aureus and E. coli with very strong categories (16,6 mm). extract Eudistoma sp. showed the presence of antibacterial activity with inhibition S. aureus and E. coli in the medium category (9 mm). The water fraction found active in antibacterial testing is then tested using a UV spectrophotometer for anti UV testing, the result show that water fraction of the four ascidians can absorb UV-B (290-320nm) and UV-A ( 320-400nm).Keywords : Ascidian, Antibacterial, Partition, Anti- UV.
