Abstract

Mikroplastik merupakan sampah plastik yang berukuran lebih kecil dari 5 mm. Mikroplastik memiliki kandungan bahan kimia yang toksik dan berpotensi menyebabkan karsinogenik jika dikonsumsi oleh organisme, salah satunya pada organisme perairan, seperti pada ikan patin (Pangasius hypopthalmus) yang dibudidaya pada keramba jaring apung Ranu Grati, Pasuruan dan menjadi salah satu ikan konsumsi. Dalam pemberian pakan ikan berupa pelet, kemungkinan kontaminasi pelet oleh mikroplastik dapat terjadi sehingga ikan patin akan mengakumulasi mikroplastik secara tidak sengaja. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik mikroplastik secara fisik (ukuran, bentuk, dan warna) dan polimer kimianya pada daging, dan pakan ikan patin (pelet) yang dibudidayakan di Ranu Grati, Pasuruan, Jawa Timur. Karakter fisik mikroplastik diamati menggunakan mikroskop stereo dengan bantuan optilab, sedangkan karakter kimia (polimer) dengan FTIR. Kelimpahan total mikroplastik pada tiga lokasi pengambilan sampling air sebanyak 680 partikel, dengan proporsi rerata 28 partikel/L pada titik 1 (dalam KJA) 12,7 partikel/L pada titik 2 (luar KJA) dan 27,3 partikel/L pada titik 3 (tengah Rnu Grati). Ukuran mikroplastik pada pengambilan sampel air di titik 1 (dalam KJA) didominasi rentang 251-500 µm dan 1001-2000 µm, pada titik 2 (luar KJA) didominasi 251-500 µm dan 101-250 µm, pada titik 3 (tengah Rnu Grati) didominasi 1001-2000 µm, 251-500 µm, 101-250 µm, dan 501-750 µm. Mikroplastik bentuk fiber berwarna hitam mendominasi pada sampel air di titik 1 (dalam KJA), titik 2 (luar KJA)dan 3 (tengah Rnu Grati). Pada 25 sampel daging Ikan Patin, didapatkan total mikroplastik sebanyak 447 partikel. Mikroplastik pada sampel daging Ikan Patin didominasi oleh bentuk fragmen dan fiber, berwarna biru, dengan rentang ukuran 101-250 µm, serta polimer yang dijumpai adalah Nylons. Sedangkan, pada 5 sampel pelet A (tipe terapung) didapatkan total mikroplastik sebanyak 147 partikel yang didominasi oleh bentuk fragmen berwarna biru dengan rentang ukuran 100-500 µm, serta polimer yang dijumpai adalah Nylons. Pada pelet B (tipe tenggelam) didapatkan total mikroplastik sebanyak 157 partikel yang didominasi oleh bentuk fragmen berwarna biru dengan rentang ukuran 100-500 µm, serta polimer yang dijumpai adalah Nylons.

Microplastics are plastic bins that are smaller than 5 mm in size. Microplastics contain chemicals that are toxic and have the potential to be carcinogenic if consumed by an organism, one of which is aquatic organisms, such as catfish (Pangasius hypopthalmus) which is cultivated in floating net cages in Ranu Grati, Pasuruan and is one of the consumption fish. In providing fish feed in the form of pellets, the possibility of contamination of the pellets by microplastics can occur so that the catfish will accidentally accumulate microplastics. The purpose of this study was to determine the physical characteristics of microplastics (size, shape, and color) and their chemical polymers in catfish meat and feed (pellets) cultivated in Ranu Grati, Pasuruan, East Java. The physical characteristics of microplastics were observed using a stereo microscope with the help of optilab, while the chemical (polymer) characteristics were observed with FTIR. The total abundance of microplastics at the three water sampling locations was 680 particles, with an average proportion of 28 particles/L at point 1 (inside KJA) 12.7 particles/L at point 2 (outside KJA) and 27.3 particles/L at point 3 (middle of Rnu Grati). The size of microplastics in water sampling at point 1 (inside the KJA) is dominated by the range of 251-500 µm and 1001-2000 µm, at point 2 (outside the KJA) is dominated by 251-500 µm and 101-250 µm, at point 3 (middle of Rnu Grati ) dominated by 1001-2000 µm, 251-500 µm, 101-250 µm, and 501-750 µm. Microplastic in the form of black fibers dominated the water samples at point 1 (inside the KJA), point 2 (outside the KJA) and 3 (middle of Rnu Grati). In 25 samples of Patin Fish meat, a total of 447 microplastic particles were obtained. Microplastics in the catfish meat samples were dominated by fragments and fibers, blue in color, with a size range of 101-250 µm, and the polymers found were Nylons. Whereas in 5 pellet samples A (floating type) a total of 147 microplastic particles were obtained, dominated by blue fragments with a size range of 100-500 µm, and the polymers found were Nylons. In pellet B (submerged type) a total of 157 microplastic particles were obtained which were played by the shape of blue fragments with a size range of 100-500 µm, and the polymers found were Nylons
