Analisis Pencemaran Limbah Mikroplastik Pada Beberapa Jenis Ikan Di Muara Sungai Kenyamukan Sangatta, Kabupaten Kutai Timur
Summary
Researchers analyzed microplastic contamination in the gills and digestive systems of multiple fish species from the Kenyamukan River estuary in East Kutai Regency, Indonesia, using NaOH digestion and microscopy to identify microplastic types and morphologies. The study characterized the forms of microplastic pollution in a waterway stressed by fishing port operations, residential settlements, and tourism activities.
Microplastics are plastic particles smaller than 5 mm that originate from anthropogenic activities or environmental degradation. The estuarine waters of the Kenyamukan River in Sangatta, East Kutai Regency, are highly vulnerable to microplastic contamination due to intensive local activities such as fishing port operations, residential settlements, docks, and tourism sites. This study aimed to analyze the types and forms of microplastics found in several fish species inhabiting the estuarine area. The research employed a descriptive–analytical approach, with sampling conducted from March to May 2025. Fish organs analyzed included the gills and digestive system, which were extracted using NaCl solution, 10% KOH, and 30% H₂O₂, followed by observation under a stereo microscope. The results revealed the presence of microplastics in goatfish (Parupeneus indicus), spotted scat (Scatophagus sp.), rabbitfish (Siganus guttatus), and golden snapper (Lutjanus johnii). The identified microplastic types consisted of fibers (52%), fragments (27%), films (12%), and pellets (9%), with a total of 173 particles. The microplastic sizes ranged from 0.0012 mm to 0.1399 mm and exhibited various colors, including black, red, yellow, blue, green, transparent, orange, and pink. These findings indicate a high level of microplastic contamination in the Kenyamukan River estuary, posing potential threats to the aquatic ecosystem and the trophic food chain.

Analisis Kandungan Mikroplastik Pada Saluran Pencernaan Ikan Di Ppi Selili Samarinda Kalimantan Timur
Researchers examined the digestive tracts of five commercially important fish species caught at a fish landing site in East Kalimantan, Indonesia, and found microplastics in all of them, with fibres and fragments being the most common types. This documents microplastic contamination in seafood from Indonesian waters and raises concerns about human dietary exposure through fish consumption.
Analisis Kandungan Mikroplastik Pada Ikan Pelagis Dan Demersal Yang Didaratkan Di Pelabuhan Perikanan Banjar Raya Banjarmasin Provinsi Kalimantan Selatan
Researchers examined microplastic contamination in both pelagic and demersal fish landed at a fishing port in South Kalimantan, Indonesia, finding an average of 8.3 microplastic particles per pelagic individual and 5.1 per demersal individual with moderate overall pollution levels. Fibres and fragments were the dominant forms detected. These findings demonstrate that commercially caught fish in Indonesian waters carry microplastics into the human food supply.
