UJI TOKSISITAS LUMPUR MINYAK BUMI SEBELUM DAN SESUDAH FITOREMEDIASI DAN PENGARUHNYA TERHADAP REPRODUKSI DAPHNIA CARINATA KING

ABSTRAK: The aim of this research is to observe lethal toxicity level LC50-48 hours  medium of oil sludges pre and post phytoremediation to Daphnia carinata and also its influence to reproduction of D. carinata . The research done with experimental method. To get LC50-48 hours value, used static bioassay according to standard of APHA (1995). LC50-48 hours value counted with  Minitab Probit Analysis. For chronic toxicity test medium of sludges oil pre and post phytoremediation to reproduction of D. carinata , using completely randomized design with two factorial pattern : 2x7, two stages of medium of oil sludges pre and post phytoremediation and seven stages of  medium of sludges oil pre and post phytoremediation concentrations. The parameter which counted is the total of neonates D. carinata during 21 days. Data analysis for chronic toxicity test used Anova test. The result show that LC50­-48 hours value of medium of oil sludges pre phytoremediation is amount 28,62 ppm and post phytoremediation is amount 126,55 ppm. For chronic toxicity test, the rate from the total of neonates D. carinata in medium of sludges oil pre phytoremediation is amount 109 neonates and post phytoremediation is amount 133 neonates
