Identifikasi Keberadaan Mikroplastik pada Insang dan Pencernaan Barbodes binotatus Di Sungai Kalilo Pengantigan Banyuwangi
Summary
An Indonesian study found microplastics in both the gill tissues and digestive tracts of Barbodes binotatus fish caught from the Kalilo River, identifying fragments and fibers as the predominant types. The presence of microplastics in fish tissues from a river system reflects the accumulation of plastic pollution in aquatic food chains.
Mikroplastik merupakan potongan atau serpihan plastik berukuran kecil <5mm yang berpotensi mengancam kesehatan maupun lingkungan. Keberadaan dari mikroplastik ini sangat berpotensi terakumulasi pada organ ikan utamanya dari jenis Barbodes binotatus yang ditangkap dari perairan sungai Kalilo. Meningkatnya jumlah penduduk berpotensi dalam pencemaran mikroplastik yang kemudian terakumulasi pada organ insang maupun saluran pencernaan. Tujuan dari penelitian ini untuk mengetahui jenis mikroplastik yang terakumulasi pada insang dan saluran pencernaa dari ikan Barbodes binotatus yang ditangkap dari sungai Kalilo Banyuwangi. Penelitian ini dilakukan di bulan Agustus-September. Metode yang digunakan bersifat purposif sampling ditujuh titik pengamatan dengan didapatkan 14 individu untuk diambi organ insang maupun saluran pencernaannya. Hasil yang didapatkan dari penelitian ini didapatkan tiga jenis mikroplastik yaitu fragment, fiber, dan film. Sedangkan pada saluran pencernaan didapatkan empat jenis mikroplastik dari jenis fragment, fiber, granul dan film. Untuk kelimpahan tertinggi didapatkan dari saluran pencernaan yaitu sebesar mikroplastik 7,34 partikel/gr, sedangkan pada organ insang hanya didapatkan kelimpahan 2,47 partikel/gr.

Contamination of microplastics in Brantas River, East Java, Indonesia and its distribution in gills and digestive tracts of fish Gambusia affinis
Researchers sampled water, gills, and digestive tracts of fish in Indonesia's Brantas River and found microplastics in all three, with fragments under 0.1 mm making up the majority — demonstrating that river fish are actively ingesting microplastics that then accumulate in their bodies.
THE ABUNDANCE OF MICROPLASTICS IN THE DIGESTIVE SYSTEM OF SILVER BARB (Barbonymus gonionotus) FROM THE WATERS OF THE KARANG MUMUS RIVER, SAMARINDA CITY, INDONESIA
Microplastics were found in all 20 silver barb fish examined from the Karang Mumus River in Samarinda, Indonesia, with an average of 22 particles per fish — mostly fiber-shaped and predominantly polyethylene. This is the first report of microplastic ingestion by fish in this river system, indicating that microplastic contamination has reached even rivers in less-studied parts of Southeast Asia. The results raise food safety concerns since silver barb is eaten by local communities, and suggest broader environmental contamination of the river ecosystem.
IDENTIFIKASI TIPE DAN KELIMPAHAN MIKROPLASTIK PADA IKAN NILA (Oreochromis niloticus) DI WADUK LAHOR KABUPATEN MALANG JAWA TIMUR
This Indonesian-language study examined microplastic contamination in the digestive tracts of Nile tilapia farmed in Lahor Reservoir, East Java, finding plastic particles at multiple sampling stations across the reservoir. Because tilapia is a widely consumed fish in the region, the results point to a direct route through which microplastics — sourced from inflowing rivers and residential areas — can enter the human food chain.
Analisis Kelimpahan Mikroplastik pada Organ Insang dan Usus Ikan Nila (Oreochromis niloticus) di Perairan Tukad Badung, Bali
Researchers analyzed the abundance and characteristics of microplastics found in the gill and intestine organs of Nile tilapia (Oreochromis niloticus) sampled from the Tukad Badung waterway in Bali, Indonesia, finding evidence of microplastic accumulation in both tissue types.
Identification of the composition and abundance of microplastics in the digestive tract of fish in the Banjaran River, Banyumas District
Researchers identified and quantified microplastic composition and abundance in digestive tract contents of wild-caught fish from a coastal fishery, documenting ingestion rates, polymer types, and particle morphologies across multiple commercially important species.
