Abstract

Sampah plastik yang masuk ke perairan terurai melalui proses kimia, fisika maupun biologis dan membentuk fragmen kecil yang kemudian disebut mikroplastik. Permasalahan mikroplastik tidak hanya ada pada biota laut, perairan laut dan sedimen laut tetapi juga terjadi pada perairan tawar. Pencemaran mikroplastik di perairan tawar dapat dijumpai di sungai, danau, rawa, bendungan dan juga tambak. Di daerah pertambakan keberadaan mikroplastik pada badan air berpotensi menyebabkan adanya kontaminasi mikroplastik pada hewan budidaya. Tujuan dari penelitian ini yaitu mengidentifikasi dan menganalisis kelimpahan mikroplastik pada udang vaname (Litopenaeus vannamei) organ cephalothorax dan abdomen, air, dan sedimen di Tambak Benowo, Surabaya. Karakter fisik mikroplastik diamati menggunakan mikroskop stereo dengan bantuan optilab dan karakter kimia menggunakan FTIR-ATR. Hasil penelitian menunjukkan total rata-rata mikroplastik 50 udang vaname pada organ cephalothorax sebanyak 17,40 partikel/gram dan organ abdomen sebanyak 14,58 partikel/gram. Kelimpahan mikroplastik pada air titik 1 sebanyak 4,22 partikel/liter dan air titik 2 sebanyak 3,38 partikel/liter. Pada titik 1 kelimpahan pada sedimen sebanyak 3,88 partikel/gram dan titik 2 sebanyak 3,3 partikel/gram. Bentuk mikroplastik paling dominan pada udang, air dan sedimen adalah fragmen, warna paling dominan adalah hitam dan ukuran dominan adalah 20-40 µm. Uji Mann Whitney dengan nilai sig. 0,007 hasil ini menunjukkan ada perbedaan antara kelimpahan mikroplastik pada organ cephalothorax dan abdomen. Uji korelasi Pearson sebesar 0,021 menunjukkan bahwa tidak ada korelasi antara panjang udang dengan kelimpahan mikroplastik. Uji polimer memberikan hasil jenis mikroplastik pada bentuknya adalah Polyvinyl Chloride (PVC), Polyacrylonitrile (PAN) dan Polypropylene (PP).

Plastic waste that enters the waters decomposes through chemical, physical and biological processes and forms small fragments which are then called microplastics. The problem of microplastics does not only exist in marine biota, marine waters and marine sediments but also occurs in fresh waters. Microplastic pollution in fresh waters can be found in rivers, lakes, swamps, dams and ponds. In pond areas, the presence of microplastics in water bodies has the potential to cause microplastic contamination of farmed animals. The purpose of this study was to identify and analyze the abundance of microplastics in vannamei shrimp (Litopenaeus vannamei) cephalothorax and abdomen, water, and sediment in Benowo Pond, Surabaya. The physical characteristics of microplastics were observed using a stereo microscope with the help of optilab and the chemical characteristics using FTIR-ATR. The results showed that the average total microplastic of 50 vannamei shrimp in the cephalothorax organ was 17.40 particles/gram and the abdominal organs was 14.58 particles/gram. The abundance of microplastics in point 1 water was 4.22 particles/liter and point 2 water was 3.38 particles/liter. At point 1 the abundance in sediment was 3.88 particles/gram and point 2 was 3.3 particles/gram. The most dominant form of microplastic in shrimp, water and sediment is fragment, the dominant color is black and the dominant size is 20-40 µm. Mann Whitney test with sig. 0.007 This result indicates that there is a difference between the abundance of microplastics in the cephalothorax and abdomen. The Pearson correlation test of 0.021 shows that there is no correlation between shrimp length and microplastic abundance. The polymer test gave results on the types of microplastics in their forms, namely Polyvinyl Chloride (PVC), Polyacrylonitrile (PAN) and Polypropylene (PP).
