Deteksi Keberadaan Mikroplastik Pada Sedimen Perairan Sungai Musi Wilayah Sekayu, Musi Banyuasin
AI summary Read the abstract
Researchers detected microplastics in sediments from the Musi River in Sekayu, South Sumatra, finding foam, fiber, and fragment morphotypes with brown-colored particles dominant at 6 particles per 50g dry sediment, with sizes ranging from 277 to 1,175 micrometers.
Potongan plastik berukuran mikro (<5 mm) dapat ditemukan di sedimen suatu perairan yang disebut mikroplastik. Sungai Musi sebagai salah satu sungai besar di Sumatera Selatan yang diketahui memiliki tingkat cemaran mikroplastik cukup tinggi. Wilayah perairan Sekayu merupakan salah satu bagian yang dilalui arus sungai Musi dengan daerah pinggiran sungai yang padat penduduknya. Penelitian ini bertujuan untuk mendeteksi keberadaan mikroplastik pada sedimen perairan sungai Musi wilayah Sekayu, Musi Banyuasin. Penelitian ini bersifat deskriptif analitik dengan pengambilan sampel sedimen sungai diambil pada bulan Juni hingga November 2023 dengan metode purpossive sampling pada dasar sungai serta dilakukan pengulangan 3 kali. Hasil penelitian menunjukkan keberadaan mikroplastik berbentuk foam, fiber dan fragmen. Warna dari mikroplastik ditemukan warna hitam dan coklat dengan warna coklat yang dominan (6 partikel/50gram sedimen kering). Ukuran mikroplastik terbesar ditemukan yaitu fiber berukuran 1175,29µm dan ukuran terkecil yaitu foam berukuran 276,72µm. Deteksi keberadaan mikroplastik pada sedimen di Perairan Sungai Musi (Tengah) wilayah Sekayu Kabupaten Musi Banyuasin menunjukkan variasi mikroplastik didominasi oleh bentuk fiber dan film, warna coklat (6 partikel/50gram sedimen kering) serta rata-rata ukuran dari 8 partikel/50gram sedimen kering mikroplastik yaitu 575,21 ?m
