【 摘 要 】

Sediments have been used as an indicator of environmental pollution because of its role as a final sink for most of materials. This study aims to describe the chemical characteristics of 13 metal contents in surface sediments and to predict the source of metal using enrichment factor (EF) approach. During the Java-Makassar-Flores (JMF) Triangle experiment in August 2015, about 11 surface sediment samples were collected using Multicore Octopus. Here we analyzed only three sediment samples at sampling station close to the coast of Java (MC-09), at mid-Java Sea (MC-11) and close to the coast of Kalimantan (MC-13). The result show that surface sediments consist of olive loose sand to silty clay containing organic materials, foraminifera shells, fragments of litic and quartz with dominant color of olive. The result of total metal analysis yields Al as the most dominant element in all stations. The enrichment factor (EF) revealed that the surface sediments of Java Sea enriched in As, Zn and Co at MC-09, wtih Zn and Ni MC-11 and with Cu, As, Zn, Ni and Cr at MC-13. All surface sediments have indicated medium contamination of Zn.
