Identifikasi Sampah Penghasil Mikroplastik di Hilir Sungai Tembuku Kota Jambi
AI summary Read the abstract
Researchers identified and characterized plastic waste types and microplastic content in the water of the Tembuku River in Jambi City, Indonesia, finding microplastic abundances of 590–850 particles/liter dominated by PET, LDPE, PP, and PS polymer types, with Pollution Load Index ratings in the very high category.
Sebagian besar plastik yang terbuang ke lingkungan akan mengakibatkan timbulan sampah plastik. Sampah plastik yang terfragmentasi menjadi berukuran <5 mm disebut mikroplastik. Tujuan dari penelitian ini adalah untuk mengetahui jenis sampah plastik dan kandungan mikroplastik pada air sungai di daerah Hilir Aliran Sungai Tembuku, maka dari itu perlu dilakukan identifikasi dengan metode kuantitatif. Jenis sampah plastik yang teridentifikasi dengan klasifikasi sesuai dengan ASTM International Resin Identification Coding System adalah: Polyethylene terephthalate (PET); Low density polyethylene (LDPE); Polypropylene (PP); Polystyrene (PS); dan Other (O). Kelimpahan mikroplastik ditemukan berkisar antara 590 sampai dengan 850 partikel/liter. Dari hasil penelitian menunjukkan bahwa Polymer Risk Index (PRI) pada sampel air sungai berada pada kategori sedang dan Pollution Load Index berada pada kategori sangat tinggi. Dibutuhkan adanya pengendalian pencemaran sampah plastik ke lingkungan terutama daerah aliran sungai seperti pemilahan sampah dari rumah, penambahan tempat pembuangan sementara dan regulasi terkait penanganan maupun mitigasi masalah terkait pencemaran mikroplastik ke lingkungan

Analysis of the Relationship Between Microplastic Abundance and the Presence of Plastic Waste in the Mahakam River, Muara Kaman District
AI summary Read the abstract
Indonesian-language research linked the abundance of plastic debris in the Mahakam River to the concentration of microplastics in the water, confirming that larger plastic waste is a direct source of microplastic contamination in this river system. The study supports the importance of plastic litter control as a strategy to reduce microplastic pollution.

AI summary Read the abstract
Researchers measured microplastic abundance in the Batanghari River in the Nipah Panjang area of East Jambi, Indonesia. Microplastics were found in river samples, with the community's practice of dumping plastic waste into the river identified as a key source. The findings call for improved waste management and public education in communities adjacent to Indonesian rivers.
