Abstract: The development of industrial area in Medan City, North Sumatera impact for the increasing soil polluted by heavy metal at the area. Phytoremediation is an emerging technology for cleaning up contaminated sites, which is inovatif, cost effective, safety and has aesthetic advantages and long term applicability. The important aspect to be noted was the plant should not be used for consumption crops. The goal of our research was to develop the phytoremediation technology by testing different ornamental plant planting under different concentration contaminated soil. So that the plant can use as a phytoremediator agent to recover the land condition at Medan Industrial Area. The experiments included eight ornamental crops such as: Sanseviera trifasciata, Dracaena fragrans, Diffenbachia sp., Phylodendron hederaceam, Agave sp.Codiatum variegatum, :Anthurium crystallium and Chrysalidocarpus lutescens The parameters are biomass production and heavy metal uptake by plant. The result showed that the greatest increase in biomass production contained in Diffenbachia sp. followed by Codiatum variegatum, Chrysalidocarpus lutescens, Sanseviera trifasciata and Dracaena fragrans respectively. Uptake heavy metal is higher at Codiatum variegatum (291 mg/kg) followed by Diffenbachia sp. (246 mg/kg), Chrysalidocarpus lutescens (185 mg/kg), Sanseviera trifasciata (162 mg/kg) and Dracaena fragrans (102 mg/kg).
