ClearDistribusi Mikroplastik Pada Sedimen Di Perairan Teluk Kendari
This Indonesian study (in Bahasa Indonesia) examined the distribution and abundance of microplastics in sediments from Kendari Bay, finding widespread contamination across sampling sites. The results add to growing evidence of microplastic accumulation in coastal sediment environments in Southeast Asia.
Microplastic Distribution in Sediments in Coastal of Pariaman City, West Sumatera Province
Indonesian researchers surveyed microplastic distribution in sediments along the coast of Pariaman City, West Sumatra, finding plastic particles throughout the study area. Higher concentrations near tourism areas and residential zones suggest that local human activities are the primary sources of coastal microplastic contamination.
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.
Abundance of microplastic in sediment around the west coast of Situbondo, East Java
Microplastic abundance was surveyed in beach sediments along the west coast of Situbondo, East Java, Indonesia, finding contamination at all seven sampled beaches with patterns reflecting local plastic use, waste management, and oceanographic transport.
Microplastics distribution on the beach sediment based on satellite remote sensing: A case study in Bali, Indonesia
Researchers examined how seasonal ocean currents and tourism activity influence microplastic distribution across three beaches in Bali, Indonesia, between January and July 2024. The study integrated polymer-level characterization with site-specific hydrodynamic data and satellite remote sensing to map microplastic accumulation patterns in beach sediments.
Distribution and Types of Microplastics in Coastal Sediments of Sepanjang Beach
Researchers characterised the distribution and types of microplastics in coastal sediments of Sepanjang Beach, Indonesia, examining microplastic presence in relation to gastropod digestive tract contamination in the local marine environment.
Linking the Tourism Activity to the Occurrence and Distribution of Microplastics
Researchers assessed microplastic abundance, type, and spatial distribution in coastal water, sediments, and fish across three zones of Gili Trawangan, Indonesia, finding that tourism-related activities concentrated microplastics at recreational beaches with concentrations reaching 19.25 particles/L.
Concentration, distribution, and characteristics of microplastic in estuary, coast and marine organisms in Indonesia: A Preliminary Review
This preliminary review mapped microplastic concentrations and characteristics in estuaries, coastal sediments, and marine organisms across Indonesia based on published studies. Microplastics were widespread across all compartments studied, with fibers dominant in many locations. The review identifies significant data gaps and calls for more coordinated monitoring to understand Indonesia's marine plastic pollution problem.
A novel report on the occurrence of microplastics in Pekalongan River Estuary, Java Island, Indonesia
Researchers measured microplastic contamination in water and sediments of the Pekalongan River estuary in Indonesia, finding concentrations of 45.2-99.1 particles/L in water and 0.77-1.01 particles/g in sediment. Polystyrene, polyester, and polyamide were the dominant polymers, with fragments and films smaller than 1 mm accounting for the majority.
Occurrence and distribution of microplastics in the beach sediment of Anday Beach, West Papua (Indonesia)
Researchers measured microplastic occurrence and distribution in beach sediments at Anday Beach in West Papua, Indonesia, finding microplastics present across sampling sites. The findings document plastic contamination reaching a relatively remote Indonesian coastal area.
Microplastic Distribution in Beach Sediments: Comparison Between the North and South Waters of East Java Island, Indonesia
Researchers compared microplastic concentrations in beach sediments on the north (Java Sea) versus south (Indian Ocean) sides of eastern Java Island, Indonesia, finding higher levels on the northern beaches that are closer to major population centers and shipping lanes. Fiber shapes and blue color dominated across all sites, and concentrations ranged from about 55 to 103 particles per kilogram. The study highlights how local population density, coastal morphology, and ocean current patterns together shape where microplastics accumulate on tropical beaches.
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.
Microplastic Abundance in Sediment in Pangandaran Waters, West Java, Indonesia
Researchers measured microplastic abundance in sediments at multiple stations in Pangandaran waters, West Java, Indonesia, finding the highest counts at station 2 (12,622 particles, mostly fibers and fragments) and the lowest at station 4 (1,809 particles). The study identifies oceanographic factors — currents, waves, and tides — as key drivers of microplastic movement and accumulation patterns in coastal Indonesian waters.
Spatial and temporal trends of microplastic contamination in surface sediment of Benoa Bay: An urban estuary in Bali-Indonesia
Researchers examined microplastic contamination in sediments of Benoa Bay, an urban estuary in Bali, Indonesia, across rainy and dry seasons. The study found concentrations ranging from 9.51 to 90.60 particles per kilogram, with the highest levels near a landfill site, and polyethylene, polypropylene, and polystyrene were the most commonly identified polymers.
Microplastic abundance and distribution in surface water and sediment collected from the coastal area
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.
Microplastic Pollution in Indonesia: The Contribution of Human Activity to the Abundance of Microplastics
This systematic review of Indonesian microplastic research found that coastal and marine sediments have the highest microplastic abundances, driven by widespread use of cheap single-use plastics and poor waste management across urban and rural areas.
Distribution of Microplastics in Coastal Waters and Their Implications for the Marine Food Chain
Researchers sampled surface water, sediments, and marine organisms from urban, industrial, and conservation coastal zones in Indonesia to assess microplastic distribution and food chain implications. Industrial zones had the highest microplastic concentrations, and filter feeders accumulated more particles than fin fish, indicating distinct exposure pathways through the marine food web.
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.
