Identifikasi Keberadaan Mikroplastik pada Insang dan Pencernaan Barbodes binotatus Di Sungai Kalilo Pengantigan Banyuwangi
AI summary Read the abstract
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
AI summary Read the abstract
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.
Identifikasi Mikroplastik pada Lambung Ikan Hasil Tangkapan Nelayan di Sungai Barito Kalimantan Selatan
AI summary Read the abstract
This Indonesian study identified and counted microplastics found in the stomachs of fish caught in the Barito River in South Kalimantan. Detecting microplastics inside fish tissue confirms that plastic particles are being ingested by wild fish in this river system, raising concerns about contamination of local food sources.
THE ABUNDANCE OF MICROPLASTICS IN THE DIGESTIVE SYSTEM OF SILVER BARB (Barbonymus gonionotus) FROM THE WATERS OF THE KARANG MUMUS RIVER, SAMARINDA CITY, INDONESIA
AI summary Read the abstract
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.
Identification of Types and Abundance of Microplastics in Nile Tilapia (Oreochromis niloticus) in Lahor Reservoir, Malang Regency, East Java
AI summary Read the abstract
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.
