Abstract
Mikroplastik merupakan plastik yang berukuran antara 1 µm-5 mm. Mikroplastik ada di lingkungan baik udara, tanah, air tawar, dan laut. Aktivitas didalam maupun diluar kawasan perairan danau dapat menimbulkan pencemaran, salah satunya adalah pencemaran mikroplastik. Keberadaan mikroplastik di perairan danau dapat berpotensi masuk pada organisme perairan termasuk Ikan Patin Siam sebagai salah satu ikan budidaya yang sering dipasarkan di Indonesia. Tujuan penelitian ini adalah untuk mengetahui karakteristik mikroplastik pada air, insang, dan saluran gastrointestinal ikan Patin Siam (Pangasius hypophthalmus) di keramba jaring apung, Ranu Grati, Pasuruan, Jawa Timur. Identifikasi karakter visual mikroplastik dilakukan dengan menggunakan mikroskop stereo dengan bantuan software optilab viewer, sedangkan karakter kimia mikroplastik dianalisis dengan menggunakan Fourier Transform Infra-Red (FTIR). Hasil penelitian dari 25 sampel Ikan Patin, didapatkan total mikroplastik pada masing-masing organ insang sebanyak 483 partikel dan pada saluran gastrointestinal sebanyak 430 partikel. Berdasarkan hasil uji Shapiro-Wilk, Data terdeteksi tidak terdistribusi normal sehingga perlu uji lanjutan Mann-Whitney U test dengan membandingkan jumlah mikroplastik pada organ insang dan saluran gastrointestinal. Hasil uji Mann-Whitney U test diperoleh nilai signifikansi sebesar 0,067 (>0,05) sehingga dinyatakan bahwa tidak ada perbedaan yang nyata untuk jumlah mikroplastik di organ insang dan saluran gastrointestinal. Mikroplastik pada bagian insang dan saluran gastrointestinal keduanya didominasi oleh bentuk fiber, warna biru, dan rentang ukuran antara 101-250 µm pada insang dan 1001-2000 µm pada saluran gastrointestinal. Polimer pada bagian insang terdeteksi Ethylene Propylene Diene Monomer (EPDM), sedangkan di bagian saluran gastrointestinal terdeteksi polyethylene (PE). Kelimpahan total mikroplastik pada tiga lokasi pengambilan sampling air sebanyak 680 partikel, dengan proporsi rerata 2,8 partikel/L pada lokasi 1, 1,27 partikel/L pada lokasi 2, dan 2,73 partikel/L pada lokasi 3. Ukuran mikroplastik pada pengambilan sampel air di lokasi 1 dan 2 didominasi rentang 101-250 µm dan 1001-2000 µm pada lokasi 3. Sementara mikroplastik bentuk fiber berwarna hitam mendominasi pada sampel air di lokasi 1 dan 3, sedangkan bentuk fim warna transparan mendominasi di lokasi 2. Polimer yang didapatkan pada sampel air adalah polyethylene(PE)

Microplastics are plastics measuring between 1 µm to 5 mm. Microplastics exist in the air, soil, fresh water, and sea environments. Activities inside or outside the lake water area can cause pollution, one of which is microplastic pollution. The presence of microplastics in lake waters can potentially enter aquatic organisms, including the Siamese catfish as one of the cultivated fish that is often marketed in Indonesia. The purpose of this study was to determine the characteristics of microplastics in the water, gills, and gastrointestinal tract of Siamese catfish (Pangasius hypophthalmus) in floating net cages, Ranu Grati, Pasuruan, East Java. Identification of the visual character of microplastics was carried out using a microscope stereo with the help of optilab viewer software, while the chemical characters of microplastics were analyzed using Fourier Transform Infra-Red (FTIR). The results of the study of 25 samples of Siamese catfish, obtained a total of 483 particles of microplastic in each gill organ and 430 particles in the gastrointestinal tract. Based on the results of the Shapiro-Wilk test, the detected data was not normally distributed, so further Mann-Whitney U test was needed by comparing the number of microplastics in the gills and gastrointestinal tract. The results of the MannWhitney U test obtained a significance value of 0.067 (> 0.05) so that it was stated that there was no significant difference in the number of microplastics in the gills and gastrointestinal tract. Microplastics in the gills and gastrointestinal tract are both dominated by fiber shape, blue color, and the size range is between 101-250 µm in the gills and 1001-2000 µm in the gastrointestinal tract. The chemical polymer in the gills detected was Ethylene Propylene Diene Monomer (EPDM), while polyethylene (PE) was detected in the gastrointestinal tract. The total abundance of microplastics at the three water sampling locations was 680 particles, with an average proportion of 2.8 particles/L at location 1, 1.27 particles/L at location 2, and 2.73 particles/L at location 3. The size of microplastics in water sampling at locations 1 and 2 was dominated by the range of 101-250 µm and 1001-2000 µm at location 3. Meanwhile, microplastics in the form of fiber and black color dominated the water samples at locations 1 and 3, while fim forms and transparent colors dominated at location 2. The polymer obtained in the tested water samples is polyethylene (PE)
