ClearModeling 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.
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.
Korelasi Konsentrasi Mikroplastik dengan Material Padatan Tersuspensi (MPT) di Perairan Delta Sungai Bodri, Kendal, Jawa Tengah
Researchers examined the correlation between microplastic concentration and total suspended solids in waters of the Bodri River delta in Central Java, Indonesia, collecting 16 water samples across eight stations during both high and low tides in the dry season, finding a relationship between sediment load and microplastic distribution in this coastal system.
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.
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.
Spatial distribution of microplastic in sediment of the Citanduy River, West Java, Indonesia
This study mapped the spatial distribution of microplastics in sediments along the Citanduy River in West Java, Indonesia, finding widespread contamination that varied by location and land use. Rivers like the Citanduy act as conveyor belts carrying microplastics from inland areas to coastal and marine environments.
Evaluation of the Performance of Spline Interpolation Method in Mapping and Estimating the Total Suspended Solids over the Coastal Water of Pulau Tuba, Kedah
Spline interpolation was evaluated as a method for predicting and mapping total suspended solid concentrations in coastal waters around Pulau Tuba, Malaysia, using a limited number of sample points. The method showed acceptable accuracy for mapping suspended sediment distribution. Efficient spatial modeling methods help assess water quality across large coastal areas without exhaustive sampling.
Tidal intensity and suspended sediment concentration drive microplastic distribution in the Pearl River Estuary: Insights from remote sensing retrieval
Field measurements showed that tidal intensity and suspended sediment concentrations are key drivers of microplastic transport in coastal and estuarine waters. The results help explain why microplastic concentrations fluctuate with tidal cycles and inform models predicting where plastics accumulate in dynamic coastal zones.
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.
Analysing the influence of hydrodynamic and sedimentary factors on the microplastic distribution in the Ashtamudi estuary, India
Microplastic abundance in the Ashtamudi estuary in India ranged from 3.2 to 53 items/L, with highest concentrations near river-sea confluences; the study found microplastic distribution inversely correlated with current velocity and directly with suspended sediment concentration, enabling a predictive non-linear transport model.
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.
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.

Researchers analyzed microplastic contamination in sediments from Semarang waters in Central Java, Indonesia, documenting the types, abundance, and distribution of microplastics across multiple sampling campaigns linked to the city's high population density and waste generation.
Physico-Chemical and Biological Water Quality of Tuntang Estuary, Demak, Central Java as A Base for Sustainable River Management
This Indonesian study assessed the water quality and pollution status of the Tuntang River estuary in Central Java across wet and dry seasons, finding pollution from multiple sources. While not focused on microplastics specifically, degraded river and estuary water quality typically includes plastic pollution that accumulates in these transition zones.
Size-dependent microplastics transport in a sediment rich environment
Researchers developed a two-dimensional depth-averaged numerical model using Population Balance Equations to simulate size-dependent microplastic transport in the Scheldt estuary, accounting for interactions between cohesive and non-cohesive sediments. The model revealed that intertidal areas act as sinks trapping microplastics, while turbidity maxima zones are hotspots for suspended microplastics.
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.
