Kontaminasi Jenis Mikroplastik Pada Tubuh Ikan Tembang (sardinella Fimbriata) Di Perairan Teluk Kendari
AI summary Read the abstract
Indonesian researchers studied the types and quantities of microplastics found in the digestive tracts of fimbriate sardines (Sardinella fimbriata) collected from Kendari Bay waters. They found microplastic contamination across all sampled fish, with fibers being the most common type.
Mikroplastik merupakan bagian dari sampah plastik yang memiliki ukuran partikel kurang dari 5 mm. Mikroplastik yang terdapat di dalam perairan kemungkinan dapat ditelan organisme laut, seperti ikan tembang (Sardinella fimbriata). Penelitian ini bertujuan untuk mengetahui jenis dan jumlah setiap jenis mikroplastik yang ditemukan pada saluran pencernaan ikan tembang di Perairan Teluk Kendari. Penelitian ini dilaksanakan pada bulan Juni – September 2020. Lokasi pengambilan sampel ikan tembang berasal dari stasiun Perairan Kendari Beach, Perairan Masjid Al-Alam dan Perairan Pelabuhan Perikanan Samudera (PPS) Kendari menggunakan gillnet, selanjutnya sampel ikan tembang dimasukkan dalam cool box untuk mempertahankan kesegarannya. Analisis sampel dilakukan di Laboratorium Unit Produktivitas dan Lingkungan Perairan, Fakultas Perikanan dan Ilmu Kelautan, Universitas Halu Oleo. Pengamatan dilakukan dengan beberapa tahap yaitu tahap preparasi sampel dan identifikasi menggunakan mikroskop. Hasil penelitian menunjukan bahwa jenis mikroplastik yang ditemukan ada empat jenis yaitu jenis fiber, fragmen, film dan pellet. Mikroplastik paling tinggi ditemukan dalam saluran pencernaan ikan tembang pada penelitian ini adalah jenis film sebesar 208,6 partikel/individu (50,24%) dan terendah adalah jenis pellet yaitu 1 partikel/indindivu (0,24%). Berdasarkan lokasi penelitian, jumlah mikroplastik tertinggi ditemukan pada stasiun PPS Kendari yaitu 151,9 partikel/individu dan terendah didapatkan pada stasiun Masjid Al-Alam yaitu 123,7 partikel/individu.Kata Kunci: Mikroplastik, Ikan Tembang (Sardinella fimbriata), Perairan Teluk Kendari.

AI summary Read the abstract
Researchers identified and characterised microplastics in the digestive tracts of tamban fish (Sardinella fimbriata) caught at Tanjung Moco Harbour in Indonesia, a country identified as among the world's largest contributors to marine plastic pollution. The study documented microplastic presence, morphology, colour, and polymer composition in the fish samples, highlighting the potential for microplastic contamination to enter local seafood supply chains.

AI summary Read the abstract
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
AI summary Read the abstract
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.
