The study provides a modeling framework for understanding microplastic distribution in Indonesian coastal waters, which receive high plastic inputs from land.
Physical Control on Marine Debris Spreading around Muara Gembong, Jakarta Bay
Researchers used numerical modelling combined with artificial debris pathway analysis to investigate how marine debris from the Citarum River disperses around Muara Gembong in Jakarta Bay, finding that debris trajectory patterns differ substantially between the northwest and southeast monsoon seasons due to varying ocean currents, tides, and wind patterns.
Trajectory of microplastic particles with 2-dimensional hydrodynamic modelling approach at Pekalongan waters, Central Java, Indonesia
Researchers used two-dimensional hydrodynamic modeling to track how microplastic particles move through the waters near Pekalongan, Central Java, Indonesia. They found that tidal currents and seasonal monsoon patterns significantly influence microplastic transport and accumulation near fishing grounds. The study provides a tool for predicting microplastic hotspots that could help guide marine debris management in the region.
Modeling the fate of microplastics in the Sengkarang Estuary, Pekalongan City, Central Java, Indonesia
Researchers measured microplastic concentrations in water and sediment at the mouth of the Sengkarang River in Indonesia and built a hydrodynamic model to track how tidal currents, wind, and river flow distribute the particles. Microplastics were highest in coastal waters and mangrove sediments, with tides and currents driving horizontal transport and concentrating particles in biologically sensitive habitats. The modeling approach offers a practical framework for predicting where microplastics accumulate and informing pollution management in river-to-sea systems.

This study tracked monthly variations in marine debris discharged from the Greater Jakarta area in Indonesia, identifying land-based sources including rivers and coastal communities as major contributors. Peak discharge events correlated with rainfall patterns, highlighting the importance of monsoon-season waste management in reducing ocean plastic pollution.
The contribution of estuaries to the abundance of microplastics in Jakarta Bay, Indonesia
Researchers found that rivers draining into Jakarta Bay are a major source of microplastics, with polyethylene fragments in the 300-500 micrometer size range dominating, and that spatial variation in abundance across nine estuaries reflects differences in local land use and waste management.

Researchers found microplastics in both surface water and sediments across 12 coastal sampling sites in Jakarta Bay, Indonesia, documenting their abundance, distribution patterns, and morphological characteristics in a heavily urbanized tropical coastal environment.
Seasonal heterogeneity and a link to precipitation in the release of microplastic during COVID-19 outbreak from the Greater Jakarta area to Jakarta Bay, Indonesia
Researchers found microplastics in all nine river outlets flowing into Jakarta Bay, with concentrations linked to rainfall intensity and higher near the eastern bay where human activity is greater, highlighting storm runoff as a key pathway for land-based plastic pollution reaching the ocean.

Macroplastic fate and transport in an Amazonian Estuarine System: A Lagrangian Modelling Approach
Scientists used computer models to track how large plastic waste travels from the city of Belém, Brazil through rivers and waterways to the ocean. They found that plastic pollution gets stuck in certain areas during low water periods but moves quickly to the ocean during high water periods, creating pollution hotspots near the city. This research helps identify where plastic waste accumulates so communities can better target cleanup efforts and prevent this pollution from reaching the ocean and potentially entering our food chain.
