ClearMajor sources and monthly variations in the release of land-derived marine debris from the Greater Jakarta area, Indonesia
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.
Marine macro debris transport based on hydrodynamic model before and after reclamation in Jakarta Bay, Indonesia
This hydrodynamic modeling study predicted how marine debris would move in Jakarta Bay before and after planned land reclamation, finding that the new island configuration would alter debris transport patterns. The study is relevant to understanding how coastal development affects the distribution of plastic waste.
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.
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.
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.
Marine Debris Pathway Across Indonesian Boundary Seas
Lagrangian particle-tracking simulations modeled marine debris trajectories across Indonesian boundary seas, finding that complex ocean circulation patterns and monsoon seasonality strongly influence debris accumulation zones and cross-border transport in this archipelago region.
Microplastics Patch Based on HydrodynamicModeling in The North Indramayu, Java Sea
Hydrodynamic modeling was used to track microplastic transport in the Java Sea off North Indramayu, Indonesia, predicting accumulation zones influenced by tidal currents and seasonal winds. The study provides a modeling framework for understanding microplastic distribution in Indonesian coastal waters, which receive high plastic inputs from land.
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.
Kepadatan dan pola transport sampah laut terapung di pesisir barat perairan Teluk Ambon Luar
This Indonesian study measured the density and transport patterns of floating marine litter on the western coast of Outer Ambon Bay, finding high volumes of plastic debris with clear spatial patterns driven by currents and tides. The data can inform placement of debris interception systems in this Indonesian coastal city.
Estimation of bottom microplastic flux in the Indonesian seas
Using ocean circulation models and Lagrangian particle tracking, researchers estimated microplastic flux to the seafloor from 68 Indonesian rivers, finding that accumulation concentrates within 50-100 km of major islands. The Karimata Strait, Java Sea, and South Java were identified as the primary accumulation zones within Indonesia's Fisheries Management Areas.

This study modeled surface current patterns in Lampung Bay, Indonesia, during the second transition season using hydrodynamic modeling. Understanding coastal current patterns is relevant to predicting how microplastics and other pollutants disperse in Indonesian coastal waters.
A particle tracking model approach to determine the dispersal of riverine plastic debris released into the Indian Ocean
Researchers developed a particle tracking model to simulate the dispersal of riverine plastic debris released into the Indian Ocean from surrounding landmasses. The study found that plastic accumulation on beaches peaked during monsoon seasons, with ocean currents, wind, and wave action driving distinct transport patterns, providing valuable data for identifying high-risk coastal areas and informing cleanup strategies.
Marine Plastic Drift from the Mekong River to Southeast Asia
Using the OpenDrift ocean model with seasonal monsoon dynamics, this study simulated how plastic debris from the Mekong River spreads across Southeast Asia. Results show that most plastics end up stranding on the coastlines of the Philippines and Indonesia, with seasonal monsoon patterns strongly influencing dispersion pathways. The findings help prioritise where plastic management and clean-up efforts are most urgently needed in one of the world's most plastic-polluted regions.
Spatial and temporal distribution of microplastics in the Belawan Estuary, Indonesia
Researchers tracked microplastic levels across different tidal cycles and lunar phases in an Indonesian estuary, finding that concentrations peaked near the coastline during high tide and full moon periods. The study shows that tidal currents and seasonal water flow patterns strongly control where microplastics accumulate, which is important for designing cleanup strategies.
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.
Spatial Distribution and Quantification of Microplastic Contamination in Sediments of Kaliratu Coastal Waters, Kebumen, Indonesia
Researchers found microplastics in sediments along Kaliratu Beach in Indonesia at concentrations of 25–57.5 particles/kg, with fibres, fragments, films, and pellets all present, and used hydrodynamic modelling to trace how seasonal monsoon currents distribute them along the coastline. The findings highlight that even relatively remote Indonesian coastal areas near shrimp ponds and other anthropogenic activity are accumulating measurable plastic pollution.
