Identifikasi dan Kepadatan Mikroplastik pada Sedimen di Mempawah Mangrove Park (MMP) Kabupaten Mempawah, Kalimantan Barat
Summary
Researchers identified four types of microplastics — fibers, fragments, films, and microbeads — in sediments at a mangrove park in West Kalimantan, Indonesia. Microplastic density was highest in the shallowest sediment layer, suggesting recent deposition from surrounding activities.
Salah satu ekosistem mangrove yang diduga tercemar mikroplastik yaitu, Mempawah Mangrove Park (MMP) di Kabupaten Mempawah, Kalimantan Barat. Tujuan dari penelitian yaitu untuk mengetahui jenis dan kepadatan mikroplastik pada sedimen di Mempawah Mangrove Park (MMP), Kabupaten Mempawah, Kalimantan Barat. Hasil penelitian mendapatkan empat jenis mikroplastik, yaitu fiber, fragmen, film dan microbead. Mikroplastik memiliki kepadatan tertinggi pada stasiun I, diikuti oleh stasiun III, stasiun IV dan stasiun II. Identifikasi mikroplastik di Mempawah Mangrove Park (MMP) menunjukkan kedalaman 20-30 cm memiliki kepadatan mikroplastik lebih tinggi dibandingkan kedalaman 0-10 cm dan 10-20 cm. Uji Kruskal-Wallis yang telah dilakukan menunjukkan kepadatan jumlah mikroplastik antar stasiun dan kepadatan mikroplastik antar kedalaman tidak menunjukkan perbedaan yang signifikan (Asimpg. Sig. 0,059 > 0,05).
