Abstract

Abstract. Indonesia is an archipelagic country that has a large population. This high population has increased the amount of waste produced every year. Kalimantan is one of the regions in Indonesia that has a small population. However, large amounts of waste were found in the area around the coast of the Karimata Islands. This research goal is to figure out the source of the waste along with the characteristics of the sea current in the vicinity area of the research location. The methodology is carried out in 2 ways, including collecting primary data with the support of citizen science research within the transect method and a hydrodynamic numerical model. This research is on undergoing project, then the initial outcomes prove that hydrodynamic numerical modeling can be used as a tool to determine the source of marine debris and most of the marine debris stranded on Buluh Kecil Island and Genting Island at Karimata Islands. The characteristic marine debris movement is dominated by the north direction sea current, including waste from Vietnam, Malaysia, and Thailand.
