Spatial distribution of microplastic pollution and its relation to pollution index-based water quality status in Progo River, Indonesia
Researchers mapped microplastic distribution along Indonesia's heavily polluted Progo River, finding 75 to 436 plastic particles per cubic meter of water and showing that lower oxygen levels, higher organic pollution, and faster water flow all correlated with higher microplastic concentrations — evidence that plastic particles actively degrade river water quality.

Researchers assessed microplastic contamination in the Metro River in Indonesia, finding that abundance and characteristics varied by land use type, with urban areas showing higher concentrations of fragments and fibers in this rapidly developing region.
Correlation of Microplastic Size Distribution and Water Quality Parameters in the Upstream Brantas River
Researchers surveyed microplastic abundance and size distribution in the upstream Brantas River in Indonesia and analyzed correlations with water quality parameters, finding that smaller microplastic fragments were most prevalent and that microplastic levels related to several water quality indicators. The study contributes baseline data for managing plastic pollution in Indonesian river systems.
The concentration of microplastic in water and fish (Gambusia affinis) collected from Brantas River
Researchers measured microplastic concentrations in water and in the bodies of mosquitofish (Gambusia affinis) from the Brantas River in Malang, Indonesia, finding contamination in both. The study confirms that freshwater fish in Indonesian urban rivers are ingesting microplastics, raising concerns about human exposure through fish consumption.
Analysis of Microplastic Contamination on Water and Sediment in the Brantas Subwatershed of the Malang Area
This Indonesian study (published in Bahasa Indonesia) analyzed microplastic contamination in both water and sediment of the Brantas River sub-watershed in the Malang area, one of the most important river systems in East Java. Microplastics were found in both water and sediment samples across sampling locations, with fibers being a dominant form. The Brantas River supports millions of people for drinking water and irrigation, making evidence of microplastic contamination in this system a significant public health and environmental concern.
Impact of a municipal solid waste processing facility on microplastic pollution in Indonesia’s waterways
Researchers quantified and characterized riverine microplastic pollution in the Jangli River in Semarang City, Indonesia, and assessed the contribution of a nearby Municipal Solid Waste Temporary Processing Site (TPS) to MP contamination through water sampling and field observation. The study documents how proximity to solid waste facilities elevates microplastic concentrations in urban waterways.
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 distribution in surface water and sediment river around slum and industrial area (case study: Ciwalengke River, Majalaya district, Indonesia)
Microplastics were surveyed in surface water and sediments of the Ciwalengke River in Indonesia across slum and industrial areas, finding average concentrations of 5.85 particles/L in water and 138 items/kg in sediment with fibers as the dominant form. The study is the first to examine microplastic contamination in a slum-dominated Indonesian river environment, documenting high concentrations linked to informal waste disposal.
Pengaruh Perilaku dan Kondisi Permukiman Masyarakat Terhadap Kualitas Air di Sungai Jangkok, Kota Mataram
This Indonesian study examines how population density and household waste disposal habits affect water quality in the Jangkok River, finding domestic waste from densely populated areas is the main pollution source. Poor waste management including plastic disposal directly into rivers is a primary driver of microplastic contamination in Southeast Asian waterways.
The occurrence and abundance of microplastics in surface water of the midstream and downstream of the Cisadane River, Indonesia
Researchers investigated microplastic contamination in the Cisadane River, Indonesia, finding 13 to 113 particles per cubic meter in surface water with higher abundance downstream, dominated by polyethylene, polystyrene, and polypropylene fragments from household and industrial sources.
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.
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.
Effect of Anthropogenic Type and Depth on Microplastic Abundance in Mahakam River Water, Samarinda City
This Indonesian study measured microplastic concentrations in water from the Mahakam River at different depths and near different land use types in Samarinda city. The results showed higher plastic levels near urban and agricultural areas, providing data on plastic pollution in a major Borneo river that local communities depend on.
