Abstrak

Eichhornia crassipes is one of Indonesia's wild plant considered a weed. It is presence can disrupt ecosystems in the river, but is proven to absorb Pb and Fe, believed also that Eceng Gondok Eichhornia crassipes can absorb other metals such as Hg, Zn, Cu and Cd were included in the group with heavy metals of Pb and Fe. In addition to heavy metal sequestration, Eichhornia crassipes can also absorb pesticide residues. This research is descriptive, to determine bioaccumulator response of Pb and Cd in Pegangsaan Two river by Inductively Coupled Plasma (ICP) method. Bioaccumulator response of Eichhornia crassipes were analyzed from the stem. Based on the results of the study also showed that the Eichhornia crassipes plants are able to accumulate heavy metals of Pb and Cd. The organs most potential to absorb Cd and Pb are stem organ with average point 1 Cd : 0,056 ppm and Pb : 0,5002 ppm, then the average point 2 Cd : 0,0328 ppm and Pb : 0,0215 ppm , and the average point 3 Cd : 0.0143 ppm and Pb : 1 ppm .,293
