Abstract

Masalah pencemaran mikroplastik (MPs) di lingkungan perairan semakin mengkhawatirkan, terutama di daerah pembuangan limbah. Sungai Sumber Beling, yang mengalir di area TPA Supit Urang, Kota Malang, menjadi salah satu contoh area yang berpotensi terkontaminasi mikroplastik. Aktivitas manusia dan limbah lindi yang mengalir ke sungai ini dapat menyebabkan peningkatan akumulasi mikroplastik yang berbahaya bagi ekosistem dan kesehatan manusia. Oleh karena itu, penting untuk melakukan studi mengenai distribusi spasial dan risiko ekologis mikroplastik di sungai ini untuk memberikan gambaran yang jelas tentang kondisi lingkungan dan bahaya yang ditimbulkannya Penelitian ini melibatkan beberapa langkah utama yang dimulai dengan pengambilan sampel air sungai secara acak sederhana di Sungai Sumber Beling untuk mendapatkan sampel yang representatif. Identifikasi mikroplastik dilakukan dengan mikroskop binokular dan analisis kimia menggunakan ATR-FTIR untuk menentukan jenis polimer yang ada dalam sampel. Penilaian risiko ekologis dilakukan dengan beberapa indeks, seperti Polymer Hazard Index (PHI), Pollution Load Index (PLI), dan Potential Ecological Risk Index (PERI). Selain analisis fisik dan kimia, survei deskriptif juga dilakukan untuk mengetahui pengetahuan dan perilaku masyarakat terkait pencemaran mikroplastik. Penelitian menunjukkan kelimpahan MPs pada air lindi tinggi sebelum pengolahan 232,00 partikel/liter, namun menurun signifikan setelah melalui sistem MBR (Membrane Bioreactor) di TPA Supit Urang 63,67 partikel/liter. Sumber utama MPs di Sungai Sumber Songo berasal dari aktivitas masyarakat di pemukiman padat, dengan konsentrasi tertinggi 240,00 partikel/liter, didominasi oleh film dan fragmen. Polimer yang paling banyak ditemukan adalah PE dan PP. Penilaian risiko ekologis umumnya menunjukkan risiko kecil, kecuali di satu lokasi yang menunjukkan risiko tinggi. Pengetahuan masyarakat sekitar sungai tentang mikroplastik sangat rendah, meskipun pemanfaatan sungai untuk aktivitas sehari-hari sangat tinggi. Hal ini menunjukkan perlunya sosialisasi dan edukasi masyarakat terkait bahaya mikroplastik untuk mengurangi polusi MPs di sungai.

English Abstract

The issue of microplastic (MPs) pollution in aquatic environments is becoming increasingly alarming, particularly in areas near waste disposal sites. Sumber Beling River, which flows through the Supit Urang Landfill area in Malang City, is an example of a region potentially contaminated by microplastics. Human activities and leachate discharge into this river may lead to increased accumulation of microplastics, posing significant threats to ecosystems and human health. Therefore, it is essential to study the spatial distribution and ecological risks of microplastics in this river to provide a clear understanding of environmental conditions and associated hazards. This study involved several key steps, starting with a simple random sampling of river water from the Sumber Beling River to obtain representative samples. Microplastic identification was conducted using a binocular microscope and chemical analysis via ATRFTIR to determine the types of polymers present in the samples. Ecological risk assessment was carried out using indices such as the Polymer Hazard Index (PHI), Pollution Load Index (PLI), and Potential Ecological Risk Index (PERI). A descriptive survey was also conducted to assess community knowledge and behaviour regarding MPs pollution. The results showed that the abundance of microplastics in leachate water was high before treatment reaching 232.00 particles per liter but significantly decreased to 63.67 particles per liter after being processed through the MBR (Membrane Bioreactor) system at the Supit Urang Landfill. However, the primary source of microplastics in the Sumber Songo River was attributed to community activities in densely populated residential areas, with the highest concentration reaching 240.00 particles per litre, predominantly in the form of films and fragments. The most commonly found polymers were PE and PP. Ecological risk assessment generally indicated low risk, except for one location that showed high risk. Community knowledge about microplastics was found to be very low, despite the high utilization of the river for daily activities. These findings highlight the urgent need for public outreach and education about the dangers of microplastics to reduce pollution in the river.
