Trajectory of microplastic particles with 2-dimensional hydrodynamic modelling approach at Pekalongan waters, Central Java, Indonesia
AI summary Read the abstract
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.
This research aims to understand the extent of microplastic contamination in Pekalongan waters, Central Java, and its potential impact on fishing grounds, aligning with Indonesia's National Action Plan for Handling Marine Debris 2018-2025. The study employs a 2D hydrodynamics modelling approach with Mike 21 Software to map the spatial distribution of microplastic movement concerning fishing areas during the west and east monsoon seasons. The results showed that microplastic particles follow tidal currents in Pekalongan waters, with their movement influenced by factors such as current, wind, and tidal conditions. The trajectory of microplastics entering fishing ground areas poses potential contamination risk for fish caught by fishermen, threatening the health of marine ecosystems and the stability of their structure and function.

Modeling the fate of microplastics in the Sengkarang Estuary, Pekalongan City, Central Java, Indonesia
AI summary Read the abstract
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.

AI summary Read the abstract
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.
Numerical Simulation of River-Borne Debris Trajectories and Dispersion Patterns in Lamong Bay, Indonesia
AI summary Read the abstract
Scientists used computer modeling to track how plastic waste moves through Lamong Bay in Indonesia, finding that ocean currents and seasonal wind patterns push floating plastic debris toward river mouths and different parts of the bay depending on the time of year. This matters because that plastic breaks down into microplastics that can enter the food chain through fish and shellfish harvested from these waters, and this kind of pollution-tracking research helps identify where cleanup efforts would have the biggest impact.
