Identifikasi Keberadaan Mikroplastik pada Air Sungai Bengawan Solo Wilayah Kelurahan Nusukan Kota Surakarta, Jawa Tengah
AI summary Read the abstract
Scientists tested water at 10 spots along the Bengawan Solo River in Indonesia and found tiny plastic particles, called microplastics, in every single sample—likely coming from household trash, plastic waste, and drainage runoff. Since this river is a water source for nearby communities, this widespread contamination raises concerns about microplastics entering drinking water and the food chain, highlighting the need for better plastic waste management to protect public health.
The increasing use of plastic in daily life has led to rising microplastic pollution in aquatic environments. This study aimed to identify the presence of microplastics in the Bengawan Solo River water in the Nusukan Subdistrict, Surakarta City. Microplastic pollution in aquatic environments has become an environmental concern due to human activities, particularly domestic waste and plastic degradation. This study used a descriptive observational method with simple random sampling in determining sampling points and grab sampling in collecting water samples. Samples were collected from 10 locations in the Bengawan Solo River within the Nusukan area, with a volume of 1 liter at each point. Microplastic analysis was carried out through filtration, the addition of 30% hydrogen peroxide (H₂O₂), incubation at 60°C for 3 hours, and filtration using 0.45 µm filter paper. Microplastic identification was conducted using a binocular microscope referring to the modified NOAA (2015) method. The results showed that all water samples from the 10 observation points were positively contaminated with microplastics. The presence of microplastics was suspected to be influenced by domestic activities, plastic waste disposal, drainage channels, and river flow conditions that allowed microplastic particles to spread throughout the study area. This study concludes that the Bengawan Solo River in the Nusukan area has been comprehensively contaminated by microplastics. Therefore, better plastic waste management and environmental pollution control are needed to reduce the entry of microplastics into river waters.

Researchers analyzed water samples from the Bengawan Solo River in Surakarta, Indonesia, and found 199 microplastic particles with an average abundance of 19.9 particles per liter. Fiber-type microplastics were the most common form detected, though fragments, films, pellets, and foam were also observed. The findings confirm that this major river system is contaminated with microplastics, likely from surrounding human activities.

Researchers measured microplastic types and abundance along with heavy metal concentrations in the upper section of the Bengawan Solo River in Indonesia, finding both contaminants present across sampling sites. The co-occurrence of microplastics and heavy metals in this nationally important river raises concerns for water quality and aquatic life.
Distribusi Spasial Dan Karakteristik Mikroplastik Pada Sedimen Di Hilir Sungai Bengawan Solo: Pendekatan Morfologi, Ukuran, Dan Warna
AI summary Read the abstract
Scientists studying Indonesia's Bengawan Solo River found hundreds of tiny plastic particles per kilogram of river sediment, with levels increasing downstream as trash breaks down into smaller and smaller pieces during its journey to the sea. This matters because these microplastics—many small enough to be invisible to the naked eye—can be absorbed by fish and other aquatic life that people eat, meaning the plastic pollution we create upstream may eventually end up on our dinner plates.
First evidence of microplastics in the water and sediment of Surakarta city river basin, Indonesia
AI summary Read the abstract
Researchers conducted the first assessment of microplastic contamination in the water and sediments of the Surakarta city river basin in Indonesia. They found that fragments and fibers were the dominant microplastic types, with over half of the particles smaller than one millimeter. The study identified polystyrene, polyester, polyamide, and silicone polymers, with blue and black particles being the most common colors in water samples.
