ANALISIS KOMPOSISI UNSUR PENCEMAR (Si, Pb, DAN Ca) DALAM TOTAL SUSPENDED PARTICULATE (TSP) DI PEMBANGUNGAN JALAN (STUDI KASUS: PEMBANGUNAN JALAN KENDAL – BATAS KOTA SEMARANG, JAWA TENGAH)

Abstract


Road construction is an activity that may have a substantial temporary impact on local air quality. Road construction projects in Kendal – Semarang City produce air pollution especially Total Suspended Particulate (TSP) and pollutant elements (Si, Pb, and Ca) in TSP.  TSP and pollutant elements were analyzed to determine the concentration at the dredging of asphalt, the concreting phase, and the concrete cutting phase. The tool used in sampling the TSP is Dust Sampler and for the measurement of pollutant elements (Si, Pb and Ca) is AAS (Atomic Absorption Spectrophotometer). The highest concentration of TSP is 1199.89 g / Nm3 that found in the concrete cutting phase, for the highest concentration pollutant elements is the concentration of Ca element contained in the concrete cutting phase that is equal to 23.7 g / Nm3, and the concentrations of Pb at the stage of concreting 0.08 mg / Nm3 is the lowest concentration of pollutant elements.
