Analisis Kandungan Mikroplastik Pada Ikan Pelagis Dan Demersal Yang Didaratkan Di Pelabuhan Perikanan Banjar Raya Banjarmasin Provinsi Kalimantan Selatan
Summary
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.
Manfaat penelitian ini untuk mengetahui jumlah partikel, karakteristik yang meliputi bentuk dan warna mikroplastik dan mengetahui hubungan perbedaan jumlah partikel mikroplastik ikan pelagis dan ikan demersal, selain itu juga dapat mengetahui hubungan jumlah partikel mikroplastik dengan berat organ, bobot, dan panjang tubuh ikan pelagis dan demersal. Penentuan lokasi sampling menggunakan metode simple random sampling dengan mengumpulkan sampel ikan dari nelayan yang mendaratkan ikan. Hasil penelitian menunjukkan bahwa jumlah partikel mikroplastik pada ikan pelagis sebanyak 250 partikel dengan rata-rata 8,3 partikel/individu. Sedangkan pada ikan demersal berjumlah 152 partikel dengan rata-rata 5,07 partikel/individu, tingkat pencemaran mikroplastik tergolong sedang. Karakteristik bentuk mikroplastik yaitu fiber, film dan fragmen dengan film mendominasi seluruh sampel. Karakteristik warna dominan mikroplastik secara berurutan didominasi oleh warna transparan, hitam, merah dan biru. Hubungan perbedaan jumlah mikroplastik pada ikan pelagis dan demersal menunjukkan bahwa terdapat perbedaan signifikan. Adapun Hubungan pengaruh jumlah mikroplastik dengan berat organ, bobot dan panjang tubuh ikan diketahui tidak terdapat pengaruh hubungan yang signifikan.

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.

The presence of microplastics in the digestive tract of commercial fishes off Pantai Indah Kapuk coast, Jakarta, Indonesia
Commercial fish from nine species collected at the Pantai Indah Kapuk coast in Jakarta were dissected for microplastics, with 97.13% of 174 fish containing an average of ~12 particles per individual dominated by fibers and fragments of PE, PP, and PS. The study documents near-universal microplastic contamination in urban coastal fisheries in Indonesia with implications for seafood consumers.
