Kandungan Mikroplastik pada Air Berdasarkan Kedalaman di Waduk PLTA Koto Panjang, Kabupaten Kampar, Provinsi Riau
AI summary Read the abstract
Researchers examined the types and abundance of microplastics at five stations across different depths in the Koto Panjang hydroelectric reservoir in Riau Province, Indonesia, finding fiber, fragment, and film morphologies with film type most dominant. Microplastic abundance was highest at station 5 and varied with depth, indicating spatial heterogeneity in contamination across the reservoir.
Tujuan penelitian ini adalah untuk mengetahui tipe dan kelimpahan mikroplastik pada perairan waduk PLTA Koto Panjang. Penelitian ini dilaksanakan pada November 2021-Januari 2022 di perairan Waduk PLTA Koto Panjang. Pengambilan sampel dilakukan secara purposive sampling pada 5 stasiun penelitian. Analisis sampel dan identifikasi mikroplastik di Laboratorium Pengolahan Limbah Fakultas Perikanan dan Kelautan Universitas Riau. Hasil penelitian menunjukkan bahwa tipe mikroplastik yang teridentifikasi adalah fiber, fragmen dan film. Tipe yang paling dominan ditemukan adalah  tipe film.  Kelimpahan  mikroplastik paling banyak ditemukan di stasiun 5 dengan  kelimpahan  tertinggi pada  kedalaman  3 meter  dibawah  permukaan  air sebesar 1.267 partikel/ m3.

Researchers investigated the type, abundance, and depth distribution of microplastics in the water column of the Siak River in Riau Province, Indonesia, sampling at three stations across three depths (surface, 5 m, and 10 m) monthly from January to March 2023, identifying fibers, fragments, and films throughout all locations and depths.
Abundance of microplastic in Water Column of Lubuk Siam Lake (Oxbow) Lubuk Siam Village Siak Hulu District Kampar Regency Riau Province
AI summary Read the abstract
This study quantified microplastic abundance in the water column of Lubuk Siam Lake, an oxbow lake in Riau Province, Indonesia, through monthly sampling at three points from September to November 2020. Water samples of 100 L were filtered using plankton nets and Whatman filter paper, and microplastic morphotypes were identified under a binocular microscope, with fibers and fragments as the dominant types. The study documents the extent of microplastic contamination in this inland freshwater system and contributes baseline data for Indonesian lacustrine environments.

Microplastic Contamination in Water and Sediment at Maninjau Lake, Indonesia
AI summary Read the abstract
Researchers quantified microplastic contamination in surface water and sediment across 10 locations in Maninjau Lake, Indonesia, finding abundances ranging from 65.63 to 195.31 particles/m3 in water and 199.52 to 7,000 particles/kg dry weight in sediment. Fiber, film, fragment, and granule shapes were identified, highlighting contamination risks to a lake critical for water supply, hydroelectric energy, and aquaculture.
