Researchers assessed water quality and identified microplastics in a river in North Kalimantan, Indonesia, finding correlations between water quality parameters and microplastic abundance and characterizing the dominant polymer types and morphologies present.
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.
Microplastic pollution in lower Cimandiri River, Indonesia: early detection on the occurrence, abundance and distribution
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.
Assessment of Small-Scale Microplastics Abundance and Characterization in Urban River: A Case Study in Metro River, Indonesia

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.
