Analisis Kelimpahan Mikroplastik Pada Air Dan Gastropoda Di Sungai Bedadung Segmen Kecamatan Kaliwates Kabupaten Jember
AI summary Read the abstract
This Indonesian study measured microplastic contamination in both water and gastropod snails collected from the Bedadung River in Jember district. Finding microplastics in both the water and the tissue of snails confirms that plastic pollution is entering the local aquatic food web, with potential implications for human health through consumption of river animals.
Mikropastik merupakan debris plastik berukuran < 5 mm dan dapat mengikat kontaminan kimia serta bersifat persisten di lingkungan. Ukuran mikroplastik yang kecil semakin meningkatkan potensi bahaya mikroplastik apabila masuk ke dalam tubuh organisme akuatik. Penelitian ini bertujuan untuk menganalisis kontaminasi mikroplastik di perairan Kabupaten Jember, dengan medeteksi kelimpahan mikroplastik di air dan gastropoda. Hasil penelitian ini diperlukan untuk memberikan informasi terkait kondisi eksisting kontaminasi mikroplastik di Kabupaten Jember sebagai upaya mitigasi pencemaran plastik di Kabupaten Jember. Penelitian ini dilaksanakan pada bulan Oktober - Desember 2021. Lokasi penelitian ini adalah Segmen Sungai Bedadung di Kecamatan Kaliwates Kabupaten Jember. Metode Penelitian meliputi : 1). Persiapan, berupa penentuan lokasi penelitian; 2). Pengambilan Sampel, berupa pengambilan sampel air dan gastropoda; 3). Identifikasi Mikroplastik, meliputi destruksi sampel dan identifikasi dibawah mikroskop stereo; 5). Analisis Data, berupa penghitungan kelimpahan mikroplastik pada masing-masing sampel. Hasil penelitian menunjukkan bahwa mikroplastik ditemukan pada keseluruhan sampel, dengan rerata kelimpahan, berturur-turut air dan gastropoda sebesar 1,87 partikel/liter, 114,3 partikel/individu. Hasil ini membuktikan terjadi perpindahan polutan mikroplastik dari media air ke dalam tubuh organisme. Hasil ini juga mengindikasikan bioavaliabilitas mikroplastik di dalam tubuh organisme sehingga berpotensi terjadinya biomagnifikasi mikroplastik di perairan dan meningkatkan efek bahaya bagi top predator di perairan Sungai Bedadung Kabupaten Jember. Deseminasi hasil penelitian ini kepada masyarakat luas sangat berperan dalam mitigasi kontaminasi mikroplastik di lingkungan.

Implications of Microplastic Pollution on Environmental Health in River Ecosystems: Literature Review
AI summary Read the abstract
This Indonesian-language literature review examined the implications of microplastic pollution for environmental health in river ecosystems, drawing on global studies. The review found that microplastics disrupt aquatic food chains and pose risks to organisms and downstream human communities that depend on river water for drinking and agriculture.
Determination of Microplastic Compounds in Some Species of Freshwater Snails in Brantas River, East Java, Indonesia

This study examined microplastic contamination in three freshwater gastropod species from Indonesia's Brantas River system, documenting MP abundance and polymer types across sampling sites and species to assess contamination patterns in edible freshwater snails consumed locally.
Identifikasi Mikroplastik Pada Air, Sedimen, dan Bivalvia di Hilir Sungai Brantas
AI summary Read the abstract
This Indonesian study identified microplastics in water, sediment, and bivalves in the lower Brantas River. Plastic fragments and fibers were found across all sample types, raising food safety concerns since local communities consume shellfish from this waterway.
Contamination of Microplastics in the Gastropod Sulcospira sp. from Upstream of the Brantas River in Indonesia
AI summary Read the abstract
This Indonesian study measured microplastic contamination in water and in the freshwater gastropod Sulcospira sp. collected from five sites along the upper Brantas River, finding microplastics present in both the water and the snails' bodies across all locations. Fragment-type plastics were most common, and land use near sampling sites appeared to influence contamination levels. Because these snails are part of local food webs — and in some regions are consumed by people — their contamination raises concerns about microplastic transfer up the food chain.
Analisis Mikroplastik Pada Kerang Kijing (Pilsbryoconcha exilis) Di Sungai Perancak, Jembrana, Bali
AI summary Read the abstract
This Indonesian study examined microplastic contamination in freshwater mussels (Pilsbryoconcha exilis) from the Peranap River, finding that plastic debris in the river was a major source of microplastic exposure for these filter-feeding animals. The results raise concerns about microplastic accumulation in organisms consumed by local communities.
