Identifying the distribution and source of riverine plastic waste contamination: case study of Brantas River in Malang city

Researchers investigated microplastic concentrations and macroinvertebrate communities at three stations along the Brantas River in Malang City, Indonesia, integrating microplastic counts, SIGNAL-2 bioassessment scores, and household waste management surveys. The highest microplastic burden and lowest macroinvertebrate diversity occurred at the station where 80% of residents disposed of plastic waste directly into the river.

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.

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.

Mapping mismanaged plastic waste in Indonesia: subdistrict-level analysis through material flow from sources to the environment

Researchers found that Indonesia produces over 9 million tons of plastic waste each year, with more than 1 million tons ending up directly in rivers, drains, and illegally dumped on land. This mismanaged plastic waste breaks down into tiny particles called microplastics that can contaminate drinking water and food sources, potentially affecting human health. The study helps identify pollution hotspots where better waste management could reduce plastic entering the environment and our bodies.
