Kelimpahan Mikroplastik Pada Sedimen Pantai Wisata di Kabupaten Konawe, Sulawesi Tenggara
AI summary Read the abstract
Researchers analyzed microplastic abundance in beach sediments at tourist beaches in Konawe Regency, Southeast Sulawesi, Indonesia, identifying fiber, fragment, and film types at an average of 2,693 particles per kilogram, with the highest total contamination found at Toronipa Beach.
Laut Indonesia diperkirakan menerima pengiriman limbah plastik yang telah digunakan oleh manusia dalam jumlah antara 100.000 - 400.000ton setiap tahun. Kejadian ini dapat menjadi masalah global karena seluruh dunia memproduksi dan menggunakan plastik. Masalah yang disebabkan oleh limbah mikroplastik yaitu bahan dari mikroplastik yang mengandung senyawa kimia berbahaya bagi lingkungan dan dapat mengganggu ekosistem laut bahkan pada akhirnya dapat mengganggu kesehatan manusia. Penelitian ini bertujuan untuk menganalisis dan membandingkan kandungan mikroplastik dalam sedimen pada beberapa pantai wisata di Kabupaten Konawe, Sulawesi Tenggara. Studi ini mengidentifikasi tiga kategori mikroplastik, yaitu fiber, fragmen, dan film, dengan rata – rata kelimpahan mikroplastik seluruhnya adalah 2.693 mp/kg. Kelimpahan fiber dan fragmen tertinggi terdapat di Pantai Arunika. Mikroplastik jenis film tertinggi ditemukan di Pantai Toronipa. Kelimpahan tertinggi total mikroplastik terdapat di Pantai Toronipa.

AI summary Read the abstract
This study measures the abundance and distribution of microplastics in beach sediment samples, characterizing particle types, sizes, and polymer compositions found at coastal sites. Spatial variation in microplastic load is analyzed in relation to local sources such as tourism, fishing activity, and inland runoff. Results add to regional baseline data on coastal microplastic pollution and inform monitoring and cleanup priorities.
