Sample of sea cucumbers, Holothuria atra and Holothuria scabra taken from the waters of the panjang island, Jepara. The purpose of this study is to determine whether the bacteria symbiont on the contents of the sea cucumber potential as a probiotic for biofilter in wastewater. Waste samples were collected from the water waste location in Semarang city which was high in population density, that is Tambak Lorok area. The study included: symbional bacterial isolation, symbionary bacterial screening as potential anti-pathogenic bacteria Staphylococcus aureus and Eschericia coli, amylolytic and proteolytic enzymatic tests, identified active bacterial species by Vitex test, a wastewater quality test of 100 mL mixed with consortium bacteria with concentration of 10 mL, then stand for 4 days. Further observations include: Phosphate levels, Nitrate content, pH, water odour, watercolour. The results showed that 24 isolates were isolated from Holothuria atra and Holothuria scabra species. It was found that there is only one type of potential isolate as anti bacterial pathogen Staphylococcus aureus. There are 4 bacteria that have enzyme activity. The results of identification with the Vitex method showed potential bacterial isolates: Sphingoonas paucimobilis. Water quality test results show that the scented water becomes odourless after given the consortium symbiotic of sea cucumber. The results concluded that the bacteria consortium of the contents of the intestines of Sea Cucumber potency as wastewater biofilter.
