Microplastic occurrence and distribution were characterized for the first time in sediments from 16 sites along urban and mangrove coastal areas of East Surabaya, Indonesia. Microplastic abundances ranged from undetected to 598 items per kilogram, with higher contamination in urban areas and characteristics reflecting mixed local plastic waste sources.
The abundance of Plastic Marine Debris on Beaches in Ambon Bay
Researchers measured plastic marine debris — including large microplastics, mesoplastics, and macroplastics — on two beaches in Ambon Bay, Indonesia. The study provides baseline data on plastic pollution levels in a region with growing coastal populations and limited plastic waste management infrastructure.
The presence of microplastics in Surabaya coastal area and its correlation with conventional water quality parameters
Researchers measured microplastic presence in coastal waters of Surabaya, Indonesia, and examined correlations with marine biodiversity indicators. Elevated microplastic concentrations were associated with reduced diversity of benthic organisms at contaminated sites.
Abundance and Types of Microplastics in the Water of Sukaraja
Researchers quantified microplastic abundance and types in the coastal waters of Sukaraja, Indonesia, using random sampling at three stations during high and low tide in April 2021. A total of 3,600 particles/m3 were recorded, with fragments being the most abundant type (1,466 particles/m3) and film the least, with the highest concentrations near the main plastic waste accumulation zone.
Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia
This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.
Spatial variation of microplastic abundance and types in Bitung coastal waters, North Sulawesi: influence of fishing, residential, and port activities
Researchers sampled surface waters in Bitung coastal waters, North Sulawesi across fishing, residential, and port zones, finding the highest microplastic concentrations near the fishing area and fibers as the dominant morphological type.
Abundance and characteristics of microplastics in the northern coastal waters of Surabaya, Indonesia
Microplastics were characterized in coastal waters off Surabaya, Indonesia, with fibers as the most common shape and polyethylene terephthalate as the dominant polymer, reflecting textile and packaging waste inputs to the region.
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.
Microplastic contamination during the peak of upwelling in Maluku Sea, Indonesia
Microplastics are widespread even in the open ocean upwelling zones of Indonesia, where nutrient-rich deep water rises to the surface. Researchers found an average of 7.6 microplastic items per liter in surface waters and over 300 items per kilogram in deep-sea sediments of the Maluku Sea — with fragments and fibers dominating, and tire-related rubber polymers notably present. The findings suggest that ocean circulation patterns in these ecologically vital fishing areas are actively concentrating and redistributing plastic pollution, with implications for marine food webs and fisheries management.
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.
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.
Spatial–Vertical Distribution of Microplastics Abundance and Characteristics in the Coastal Waters of Raha City, Muna Regency
Researchers mapped the spatial and vertical distribution of microplastics in the coastal waters of Raha City, Indonesia, sampling at three stations representing different human activity levels. The harbor area showed the highest microplastic abundance, and concentrations were generally higher at the surface and mid-water layers than near the bottom. The study confirms that fisheries and harbor activities, along with river-carried waste, are major sources of microplastic pollution in these coastal waters.
