ABSTRACT
Identification and determination of heavy metal ions Cr, Fe, Cu, Zn, Cd and Pb on the dust
street around Malioboro area have been done. Malioboro area is one of the shopping centre and
pedestrian tourism place in Yogyakarta that is the most crowded area. In summer season,
Malioboro was not pleasant to visit caused by dry and hot climate, crowded and smell of exhausted
automobile. These reason have been used to select Malioboro as a place for collecting dust
sample. The dust has been obtained from five different locations such as location A station Tugu,
location B Mall Matahari, location C governor office, location D pasar Bringharjo and location E
cross section of pos office. The dust sample was analyzed to identify and determine its metal ions
contain Cr, Fe, Cu, Zn, Cd and Pb using Atomic Absorption Spectrophotometry. The result of this
experiment show that the highest concentration of ion metals at each location are Cu 656,75μg/g
at location A , Fe 548,16μg/g at location B, Fe 420,16μg/g at location C, Pb 729,16μg/g at location
D and Fe 652,16µg/g at location E
