Anthropogenic activity in coastal areas causes environmental pollution by heavy metals. One of the heavy metals that polluted seawater is Fe, which is possibly contributed by fishing boats and tourism activities. Monitoring and assessments of Fe are important to protect the environment. To solve the problem of the polluted Fe in the environment, we need to develop the method quickly. This study used a microwave optimized Bureau Community of Reference (BCR) method with variations in solvent concentration and pH to attack Fe at fraction 2 (Fe-MnO2) in sediment. The sample was collected from Pasir Putih Beach waters sediment at 5 m below sea level. The results showed that increasing the concentration of NH2OH.HCl at fraction 2 revealed the leaching process of Fe more optimally. In the analysis of the level of Fe pollution to the environment around the Pasir Putih Beach did not indicate the potential of Fe from anthropogenic activity. Most of the Fe sources in the Pasir Putih Beach area were Fe sourced from nature. © 2020 Author(s).
