Abstract

Soft coral extract of Lobophytum sp. can inhibit the growth of pathogenic bacteria with a weak to very strong category. The purpose of this study was to determine the activity of Lobophytum sp. against pathogenic bacteria Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa and analyze the concentration of Lobophytum sp. effective against pathogenic bacteria E. coli, S. aureus, and P. aeruginosa. Sampling was carried out in the waters of Pigago Island, West Pasaman Regency, West Sumatra. This research method is an experimental method and antibacterial activity test is carried out with agar diffusion diffusion technique. This soft coral extract has the potential to inhibit pathogenic bacteria. The highest inhibitory effect on E. coli bacteria was the highest yield at a concentration of 100% with a yield of 13.95 mm, in the S. aureus bacteria the highest yield at a concentration of 100% with a yield of 12.53 mm and in P.aeruginosa bacteria at a concentration of 100% was 23.87 mm.

Abstract

The Media is a material consisting of a mixture of nutrients used by microorganisms to grow and breed. Molasses and liquid waste know one of the alternative media which has the least inexpensive carbon source and is easily obtained from the waste food industry that is rich in nutrients and minerals, so it has the potential for bacterial growth of Bacillus cereus. The consetration of molasses used for growth medium is 1%; 1.5%; and 2% while liquid waste knows 8%, 10%, and 12%. Cell growth is measured by the method of Spectrophotometry, total plate count (TPC) and biomass while the incubation period of cell growth is measured every 0, 6, 12, 18, and 24 hours. The results showed from the molasses + skim milk and the tofu liquid waste + skim milk, the best medium of bacterial cell growth of B. cereus is a liquid waste know isolates K 12%. While the best growth concentrations molasses Medium bacterial B.cereus was N2% and K2%.
