Abstract

Ekosistem mangrove merupakan salah satu yang paling terdampak oleh pencemaran mikroplastik yang berasal dari aliran sungai dan aktivitas manusia di sekitarnya. Tingkat kedalaman sedimen dapat memberikan informasi mengenai kelimpahan dan jenis mikroplastik. Kajian ini bertujuan untuk mengetahui karakteristik dan kelimpahan mikroplastik pada kedalaman 1-10 cm dan 11-20 cm. Sampel sedimen diambil dari tiga stasiun dengan metode purposive sampling pada dua kedalaman yang berbeda (1-10 cm dan 11-20 cm). Sampel sedimen di ekstraksi dari sedimen dan dilakukan identifikasi menggunakan mikroskop. Ditemukan tiga jenis partikel mikroplastik pada kawasan mangrove Gunung Anyar yaitu fragmen, filamen, fiber dimana fragmen mendominasi kedua jenis kedalaman yaitu kedalaman 1-10 cm dan kedalaman 11-20 cm. Kelimpahan mikroplastik terbanyak ditemukan pada kedalaman 11-20 cm dan kelimpahan mikroplastik terendah ditemukan pada kedalaman 1-10 cm. Ambang batas kadar mikroplastik di lingkungan belum jelas sehingga perlu adanya kebijakan tegas mengenai baku mutu mikroplastik.
