Abstract

Mikroplastik merupakan partikel plastik berukuran <1-5 mm yang berpotensi terakumulasi pada biota laut, khususnya ikan predator tingkat trofik tinggi seperti Carcharhinus tjutjot (Bleeker, 1852). Penelitian ini bertujuan untuk menganalisis kelimpahan mikroplastik, mengidentifikasi tipe dan warna mikroplastik pada organ pencernaan, otot, insang dari ikan hiu C. tjutjot serta menganalisis hubungan antara dan berat organ insang, saluran pencernaan dan otot terhadap kelimpahan mikroplastik di tiap organ tersebut. Isolasi mikroplastik pada organ insang, saluran pencernaan dan otot dari 20 ikan hiu C. tjutjot dilakukan dengan cara pengeringan dalam oven, penghancuran jaringan menggunakan larutan H2O2 30% dalam water bath, penyaringan dengan kertas saring Whatman 42 dan identifikasi menggunakan mikroskop stereo. Analisis tipe polimer dilakukan menggunakan FT-IR dan analisis bahan aditif menggunakan GC-MS. Analisis data kualitatif kelimpahan mikroplastik dilakukan secara deskriptif, sedangkan data kuantitatif diuji normalitas dengan uji Saphiro-Wilk, homogenitas dengan Levene test serta uji Kruskal-Wallis. Analisis data korelasi diuji menggunakan Uji Korelasi Spearman. Hasil penelitian teridentifikasi kelimpahan mikroplastik paling tinggi pada organ insang, diikuti oleh organ otot dan organ pencernaan. Tipe fiber dan warna hitam merupakan yang paling dominan pada ikan C. tjutjot. Analisis korelasi menunjukkan adanya hubungan yang signifikan antara massa dengan kelimpahan mikroplastik pada organ pencernaan dan otot. Microplastics are plastic particles measuring <1-5 mm that have the potential to accumulate in marine biota, especially high-trophic level predatory fish such as Carcharhinus tjutjot (Bleeker, 1852). This study aims to analyze the abundance of microplastics, identify the type and color of microplastics in the digestive organs, muscles, and gills of C. tjutjot sharks, and analyze the relationship between the weight of the gills, digestive tract, and muscles and the abundance of microplastics in each organ. Isolation of microplastics in the gills, digestive tract, and muscles of 20 C. tjutjot sharks was carried out by drying in an oven, destroying the tissue using a 30% H2O2 solution in a water bath, filtering with Whatman 42 filter paper, and identification using a stereo microscope. Polymer type analysis was carried out using FT-IR and additive analysis using GC-MS. Qualitative data analysis of microplastic abundance was carried out descriptively, while quantitative data were tested for normality using the Shapiro-Wilk test, homogeneity using the Levene test, and the Kruskal-Wallis test. Correlation data analysis was tested using the Spearman Correlation Test. The study identified the highest abundance of microplastics in the gills, followed by the muscles and digestive organs. Fiber type and black color were the most prevalent in C. tjutjot. Correlation analysis showed a significant relationship between mass and microplastic abundance in the digestive organs and muscles.
