Distribution and environmental risk of microplastics pollution in freshwater of Citarum Watershed
AI summary Read the abstract
This review maps microplastic contamination throughout Indonesia's Citarum River watershed using GIS analysis and published data, finding pollution in water, sediment, and fish from upstream to downstream. Microplastics' small size and environmental persistence allow them to enter food chains and pose a serious long-term threat to freshwater quality.
The Citarum River is one of the most polluted rivers in the world because of the inadequate waste management system and community ignorance. Plastic is one of the contaminants in the Citarum watershed. In general, plastics less than 5 mm in size are defined as microplastics. Microplastics are persistent and harm the environment. This article aims to determine the potential for pollution and distribution of microplastics in freshwater systems, especially in the Citarum watershed area. Using a combination of literature study methods with Geographical Information Systems (GIS) analysis, this article explains that microplastic contamination has occurred along the Citarum watershed from upstream to downstream, found in water and sediment and fish samples. Facilitated by their small size and high stability in the environment, microplastics can move from the aquatic environment into the food chain and cause longterm damage. This case causes a severe threat to the quality of freshwater in the Citarum watershed. Therefore, this article can be used as a reference for managing pollution in the Citarum watershed area.

AI summary Read the abstract
This study mapped the spatial distribution of microplastics in sediments along the Citanduy River in West Java, Indonesia, finding widespread contamination that varied by location and land use. Rivers like the Citanduy act as conveyor belts carrying microplastics from inland areas to coastal and marine environments.

Microplastics in sediment of Indonesia waters : A systematic review of occurrence, monitoring and potential environmental risks
AI summary Read the abstract
This systematic review compiles research on microplastic pollution in Indonesian water sediments, finding widespread contamination across the country's rivers, lakes, and coastal areas. Since Indonesia is one of the world's largest archipelago nations, this plastic pollution threatens both marine ecosystems and the seafood that local communities depend on.
Identification and characteristic of microplastics in sediment and macrozoobenthos of upper Citarum River
AI summary Read the abstract
Researchers characterized microplastic particles in sediments and macrozoobenthos collected from the upper Citarum River in West Java using grab sampling and Fenton oxidation digestion. They found an average microplastic concentration of 15.7 particles per 100 g wet sediment across all sampling sites, with the highest concentration at Nanjung station, and identified textile industry discharge and accumulated plastic waste as primary contamination sources.
Impact Pollution Microplastics in Rivers in Indonesia
AI summary Read the abstract
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.
