Peringatan Dini Pencemaran Logam Berat dan Pestisida Berdasarkan Rasio Seks Anakan Daphnia sp.
Abstract: Pesticides and heavy
metal are the major contributor for environmental pollution and have been
spread out widely in aquatic environments. Daphnia sp. is a zooplankton that
mostly used to detect aquatic pollution. The aim of this research was to study
the effect of exposuring different concentration of heavy metal (Pb and Cd) and
pesticides (diazionin) to the sex ratio offspring of Daphnia sp. The experiment
composed of three kind of treatments (Cd, Pb and diazinon), each consist of 5
treatments namely 25%, 50%, 75%, 100% and 0% as control, and 4 replications.
The data was analyzed with Kruskal Walace. If there was any different in each
treatment, then was analyzed with Duncan Double Gap Test and linear regression.
The research showed that exposuring Cd, Pb and diazinon with different
concentration to the Daphnia sp. during 96 hours could increase the percentage
male offspring of Daphnia sp. Concentration of Pb, Cd and peticides gave
positive correlation to the sex ratio offspring of Daphnia sp. Further research
was needed to know the practical technology using sex ratio offspring of
Daphnia sp. to detect the level of pollution.
