Plants Dracaena marginata is a plant that is often used as a plant landscape in the city Park of Surabaya. Dracaena marginata plant is expected to absorb well air pollutants. Air pollutants come from motor vehicles.One of the harmful pollutants that can be absorbed by plants is heavy metal lead (Pb).The aim of this research is to know the role of Dracaena marginata which acts as a landscape plant and its role as absorbant of Pb metal pollutant. The aim of this research is to know the role of Dracaena marginata which acts as a landscape plant and its role as absorbent of Pb metal pollutant. The method used in this research is observational, that is identifying, measuring density and descriptive plant Dracaena marginata. The study sample was taken in two places, namely the city park which is near the big road (lots of pole) and in the park which is small, in the city parks in Surabaya. It also measured the content of Pb metal on leaves by Atomic Absorption Spectrophotometry (AAS) method. From the research results obtained data that found two varieties Dracaena marginata, namely, varieties of green and red. Dracaena marginata is a good plant to absorb Pb pollutants. Dracaena marginata can absorb many Pb metals, but the growth and development of the body is not disturbed (grows well). The conclusions of this study are (1) there are two kinds of Dracaena marginata green var and Dracaena marginata red var (2) Dracaena marginata is a bioindicator can absorb many metal Pb.
