Microplastics were detected in the lower Cimandiri River in Indonesia, with abundance and distribution varying along the river's length from upstream to the estuary. Fragment shapes dominated, suggesting degradation of larger plastic debris. The study provides early baseline data on river microplastic pollution in a developing region of Indonesia.
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.
Abundance and distribution of microplastics in Baturusa watershed of Bangka Belitung Islands Province
Scientists measured microplastic abundance and distribution in the Baturusa River watershed on Bangka Belitung Island, Indonesia, finding plastic particles at all sampling sites. Higher concentrations were found downstream and near populated areas, highlighting the role of human settlements in freshwater microplastic contamination.
Abundance of Microplastics and Hazard to the Environment in Estuary Water in Pemalang, Central Java, Indonesia
Researchers measured microplastic abundance and types at five sampling locations in the estuary waters of the Pemalang River in Central Java, Indonesia, finding persistent microplastic hazards driven by local human activities and plastic waste inputs.
Impact Pollution Microplastics in Rivers in Indonesia
This Indonesian review examines the problem of microplastic pollution in rivers across Indonesia, describing the sources, distribution, and environmental impacts of plastic debris in river ecosystems. Plastic waste from poorly managed urban and rural areas enters rivers and fragments into microplastics that accumulate throughout the water column and sediments. The findings underscore the urgent need for improved waste management infrastructure across Indonesian communities.
Preliminary Study of Microplastic Abundance in Rivers of Greater Semarang Area, Indonesia
Researchers surveyed two rivers in the Semarang region of Indonesia and found microplastics at every sampling site, with concentrations increasing downstream and polyethylene sheet fragments — likely from single-use plastic bags — being the most common type, underlining the need for better waste management to reduce plastic entering waterways.
Microplastic pollution in Deli River Medan
This study characterized microplastic pollution in the Deli River in Medan, Indonesia, finding widespread contamination with particles varying in shape, size, and polymer type. Urban rivers like the Deli are major conduits for transporting microplastics from land-based sources to coastal marine environments.
Occurrence and visual characterization of microplastics from Mahakam River at Tenggarong City, Indonesia
Researchers detected and visually characterized microplastics in water samples from the Mahakam River near Tenggarong City, Indonesia, contributing to limited freshwater microplastic data from the country that produces approximately 7.8 million tons of plastic waste annually. Microplastics were found in river samples, with fiber and fragment morphotypes dominant, reflecting local plastic waste mismanagement.
Microplastic pollution in Surabaya River Water and Aquatic Biota, Indonesia
Researchers surveyed microplastic contamination in the Surabaya River and its aquatic organisms in Indonesia, finding MPs in water, sediment, and multiple fish species, with fiber concentrations highest near densely populated urban areas and fish tissue contamination raising concerns for human exposure through seafood consumption.
Characteristics and Abundance of Microplastics Pollution in Water and Sediment in the Bogowonto River
Sampling of Indonesia's Bogowonto River found microplastic concentrations of 127–253 particles per cubic meter in water and 100–237 particles per kilogram in sediment, with fibers the dominant shape and polyamide and polypropylene the most common polymer types. The study identifies agricultural runoff, hospital waste, and domestic sewage as key sources, and shows that the river's meander pattern concentrates microplastics at certain locations — information useful for targeting mitigation efforts.
Karakteristik sampah mikroplastik di Muara Sungai DKI Jakarta
This Indonesian-language study characterized microplastics found at the mouths of rivers flowing through Jakarta. River mouths are major hotspots for plastic accumulation, as they collect debris washed from urban areas and funnel it toward coastal and marine environments.
