Abstract

This research aimed to determine the concentrations of heavy metals (Cu, Zn, Pb, Cd) pollutants in coastal sediment, Semarang. This research would be conducted in 2017 with the location of sampling and water quality measurement conducted at Usman Janatin Street, Semarang. The sample analysis would be conducted at the Diponegoro University Integrated Laboratory. In this research was focused on deep and width. According to some previous studies such as study done by Mancuso and Green (2010) that stated the TAL metals analysis results gave a wide scope of the concentration of metals in coastal urban area. Based on the analysis and result, the conclusion as follows:There was relationship between levels of heavy metals and external environment. The relationship was positive, it means the higher levels of heavy metals, the external environment would be more polluted. The lower levels of heavy metals, the external environment would be low polluted. The internal levels of coastal sediment could be used as an index to infer the state of the environmet. This heavy metals determination tool couldbe used to support policy and decision-making.
