Abstract
The high level of Fe in the waters of a material that is difficult to be degraded so that it can last a long time and are then deposited in the sediment. The Fe in sludge sediment are commonly contributed by the anthropogenic factors including waste industrial, port and agriculture. Heavy metals in the amount above the threshold can be dangerous to aquatic ecosystems and living beings around them. Tessier microwave method divides the sludge into five fractions, fraction of ion exchange, carbonate bound fraction, fraction reduction, oxidation fraction is the fraction of non-resistant and residue fraction is the fraction resistant. Each faction describes the attachment of metal in the sludge. This study was conducted to determine the concentration of Fe, fractionation and distribution of Fe attachment on each of the fractions and find out the similarities reactions that occur in sludge leaching at Prigi Beach area. The heavy metal content in Prigi Beach sludge is higher in the non-resistant fraction than the resistant and precision fraction obtained is ≤5%.
