Identifikasi Mikroplastik Pada Beberapa Jenis Ikan Di Sungai Manggar Balikpapan Sebagai Daerah Penyangga Ikn
Summary
Researchers identified and characterized microplastics in the digestive tracts of two fish species -- bete-bete (Leiognathus equulus) and mangrove snapper (Lutjanus argentimaculatus) -- from Manggar River in Balikpapan, Indonesia, a buffer zone for the new national capital. The qualitative study using light microscopy detected microplastic types including fibers, fragments, films, and monofilaments in both species.
Identifikasi Mikroplastik Pada Beberapa Jenis Ikan di Sungai Manggar Balikpapan Sebagai Daerah Penyangga IKN. Bertujuan untuk mengetahui jenis kandungan mikroplastik pada saluran pencernaan yang tedapat pada ikan bete-bete (Leiognathus equulus) dan ikan kakap mangrove (Lutjanus argentimaculatus) di Sungai Manggar. Jenis penelitian ini merupakan penelitian kualitatif dengan metode deskriptif analitis. Pengambilan sampel dilakukan dengan purposive sampling dan menggunakan tiga kali pengulangan untuk setiap jenis ikan. Identifikasi mikroplastik pada ikan dilakukan menggunakan mikroskop cahaya perbesaran 4x. Hasil Penelitian menunjukkan bahwa ditemukannya kandungan mikroplastik pada sampel ikan dengan jenis film, fragmen, fiber dan monofilamen. Mikroplastik jenis film adalah yang paling mendominasi. Pada ikan bete-bete (Leiognathus equulus) sebanyak 31 partikel mikroplastik memiliki panjang >150 µm dan sebanyak 7 partikel mikroplastik memiliki panjang <150 µm. Pada ikan kakap mangrove (Lutjanus argentimaculatus) sebanyak 19 partikel mikroplastik memiliki panjang >150 µm dan sebanyak 3 partikel mikroplastik memiliki panjang <150 µm.

Identifikasi Mikroplastik Yang Terdapat Pada Beberapa Jenis Ikan Di Perairan Sungai Sangsanga Kelurahan Sarijaya
Researchers identified microplastics in the digestive tracts of three fish species -- Toman (Channa micropeltes), Seluang (Rasbora argyrotaenia), and Nila (Oreochromis niloticus) -- from Sangasanga River in East Kalimantan, Indonesia, finding fiber, fragment, film, and monofilament particle types. Fiber-type microplastics dominated across all species, with size ranges varying by species and particle type.
Analisis Kelimpahan Mikroplastik pada Ikan Sapu-Sapu Pterygoplichthys Pardalis (Castelnau, 1855), Air, dan Sedimen di Dua Daerah Ciliwung, Jakarta Selatan
Researchers analyzed microplastic abundance in the gills and digestive tracts of suckermouth armadillo catfish, as well as in water and sediment, at two sites on the Ciliwung River in Jakarta. Both fish and environmental samples contained microplastics, with fibers as the most common type, reflecting significant plastic pollution in this urban Indonesian river.
IDENTIFIKASI MIKROPLASTIK PADA IKAN TONGKOL (Euthynnus affinis) SEBAGAI BIOINDIKATOR DI PERAIRAN TELUK KOTA KUPANG
This Indonesian study examined microplastic contamination in the digestive tracts of tongkol fish (Euthynnus affinis) from two sites in Kupang Bay. Microplastics were found in all 16 sampled fish, with fibers and fragments being the most common shapes, confirming fish as indicators of coastal plastic pollution.
Karakteristik Mikroplastik pada Ikan Kakatua Anglu (Chlorurus sordidus) dan Ikan Kurisi Sirip Pucat (Nemipterus thosaporni) di Perairan Teluk Jakarta
Microplastics were found in the gastrointestinal tracts of two fish species with different feeding habits caught in Jakarta Bay, Indonesia, with both herbivorous parrotfish and carnivorous threadfin bream affected. The findings indicate that microplastic ingestion in Jakarta Bay fisheries is widespread across the food chain, with implications for seafood safety in the region.
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.
