KEBERADAAN MIKROPLASTIK PADA IKAN SWANGGI (Priacanthus tayenus), SEDIMEN DAN AIR LAUT DI PERAIRAN PESISIR BRONDONG, KABUPATEN LAMONGAN
Summary
Researchers found microplastics in the digestive tracts of bigeye fish, in sediment, and in seawater at Brondong coastal waters in East Java, Indonesia. Fibers were the most common microplastic type, with implications for seafood safety in this active fishing region.
ABSTRAK Mikroplastik merupakan sampah plastik yang mengalami degradasi dan terurai menjadi partikel-partikel plastik yang kecil ≤ 5 mm. Keberadaan mikroplastik di perairan memungkinkan tidak sengaja termakan biota laut seperti ikan. Penelitian ini bertujuan untuk mengetahui bentuk dan jumlah mikroplastik yang terdapat pada saluran pencernaan ikan Swanggi (Priacanthus tayenus), sedimen dan air. Pengambilan sampel diambil 3 kali dengan 1 kali pengambilan sebanyak 9 sampel. Sampel ikan Swanggi yang diidentifikasi denga n melihat jenis kelaminnya dan ukurannya yaitu ukuran kecil, sedang dan besar dengan panjang 14 , 9-32 cm dan berat 44-278 , 5 g untuk ikan Swanggi jantan serta panjang 16 , 2-26 cm dan berat 56-220 g untuk betina. Hasil menunjukkan bahwa mikroplastik yang ditemukan pada saluran pencernaan ikan Swanggi (Priacathus tayenus), yaitu bentuk fiber, fragmen dan film sebesar 389 partikel/ind untuk ikan Swanggi jantan dan 382 partikel/ind untuk betina. Mikroplastik pada sedimen ditemukan bentuk fiber, fragmen dan film dengan jumlah total 363 partikel/g. Sedangkan mikroplastik pada air ditemukan bentuk fiber, fragmen dan film dengan jumlah total 444 partikel/mL. Kata Kunci: Keberadaan Mikroplastik, Fiber, Fragmen, Film, Ikan Swanggi (Priacanthus tayenus) ABSTRACT Microplastic is plastic waste which is degraded and decomposed into small plastic particle ≤ 5 mm. The presence of microplastics in the waters allows accidentally eaten by marine biota such a fish. This study aims to determine the shape and amount of microplastics found in the digestive tract of Swanggi fish (Priacanthus tayenus), sediment and water. Sampling was taken 3 times with 1 time taking as many as 9 samples. Swanggi fish samples identified by looking at their sex and size are small, medium and large with a length of 14,9-32 cm and weight of 44-278,5 g for male Swanggi fish and a length of 16,2-26 cm and a weight of 56-220 g for females. The result showed that the microplastics found in the digestive tract of swanggi fish (Pricanthus tayenus), namely the form of fiber, fragments and films were 389 particles/ind for Swanggi fish and 382 particles/ind for females. Microplastic in sediments found in the form of fiber, fragments and film with a total of 363 particles/ind. Whereas microplastic in water found in the form of fiber, fragments and films with a total of 444 particles/mL.

Analisis Komposisi Mikroplastik Pada Tiga Ikan Laut Ekonomis Penting dari Pelabuhan Perikanan di Jawa Timur, Indonesia
Researchers analyzed microplastic composition in the digestive tracts and organs of three economically important fish species -- Clupea harengus, Euthynnus affinis, and Restrelliger brachysoma -- collected from fishing ports in East Java, Indonesia, finding fibers and fragments as the dominant types. Clupea harengus exhibited the highest microplastic abundance, attributed to its inability to distinguish microplastics from planktonic prey.

Researchers analyzed microplastic content in the flesh, gills, and stomachs of two commercially important fish species from Muncar Waters, East Java, finding 1,322 total particles with the highest abundance in flesh (40%), and fragments as the dominant particle type.
Analisis Kelimpahan Mikroplastik Pada Ikan Yang Didaratkan Di Pantai Rebo Kabupaten Bangka
Researchers analyzed microplastic contamination in three commercially important fish species caught off Rebo Beach in Bangka, Indonesia, finding that fibres were the most common form and black the most frequent colour, with particles typically between 50 and 500 µm. The high contamination levels in fish guts consumed by local communities raise concerns about human dietary exposure to microplastics in this coastal region.
Identification of microplastics in water in the Sukolilo Coastal Area, Bangkalan Regency, East Java
Researchers sampling coastal waters in Bangkalan, East Java found microplastic concentrations averaging 4.32 particles per liter, with fiber, fragment, and film shapes present in a range of sizes and colors. These elevated levels in a coastal area highlight the ongoing contamination of Indonesian marine environments and the potential for microplastics to enter seafood consumed locally.
Microplastic Occurrence in Different Fish Organs from Two Coastal Waters in Java Sea, Indonesia
Researchers assessed microplastic accumulation in the gut and gill tissues of six economically important fish species from Jakarta Bay and Cirebon Bay in Indonesia. They found microplastics present in all samples, with variations in abundance and polymer type across species and locations. The study raises concerns about the potential transfer of microplastics to human consumers through commercially harvested fish in the Java Sea region.
