All rights reserved.Marine debris is an important marine environmental issue in Indonesia. The impact of marine debris pollution influences life in the coastal areas including tourist areas. The coastal area of Pelabuhan Ratu in the southern part of West Java province is well-known as a tourist area. Therefore, it is vital to understand the cycle of marine debris movement in this area. We conducted research using observation data to create a Delft3D model. The coupled hydrodynamic and trajectory models were simulated to detect marine debris movement. The generating force of this model was natural forces present in the environment; i.e., tidal and wind forces, and the flow of river discharge. Plastic is the dominant type of debris. The simulation was only run during the western monsoon when there is an extremely large amount of marine debris due to the increased rainfall. The majority of marine debris particles originate from the Cimandiri River (90%) and reaches as far as the nearest estuary, which shows the role of tidal circulation. The maximum distances from the marine debris source to the furthest trajectory are 17.49 and 15.54 kms for the discontinue and continue particle source simulations, respectively. The marine debris particles which originated from the tourist beach area move westward along the coastline, following the wind direction. After reaching the area of the estuary area, some particles enter the river, but most (98%) move to the coastal area as far as the nearest estuary.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Marine debris,Pelabuhan Ratu Bay,Trajectory model,West monsoon[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Acknowledgements.
