ANALISIS KANDUNGAN MIKROPLASTIK PADA AIR MINUM DALAM KEMASAN (AMDK) DARI SUMBER MATA AIR GUNUNG PALUNG DI KECAMATAN SUKADANA
Abstract
Abstrak: Air Minum Dalam Kemasan (AMDK) berpotensi mengandung mikroplastik yang berasal dari sumber air baku maupun dari proses pengolahan, sehingga perlu dikaji untuk mengetahui perubahan karakteristiknya hingga menjadi produk akhir. Penelitian ini bertujuan untuk menganalisis jumlah, bentuk, warna, dan kelimpahan mikroplastik pada air baku, air dari tangki penampungan, dan AMDK yang bersumber dari mata air Gunung Palung di Kecamatan Sukadana. Sampel penelitian terdiri atas tiga jenis dengan masing-masing tiga kali ulangan. Sampel air baku dianalisis melalui degradasi bahan organik menggunakan metode Wet Peroxide Oxidation, pemisahan densitas menggunakan NaCl, penyaringan dengan kertas saring Whatman No. 42, dan pengamatan mikroskopis. Sampel air dari tangki penampungan dan AMDK langsung melalui tahap penyaringan dan pengamatan mikroskopis. Hasil penelitian menunjukkan mikroplastik sebanyak 126 partikel pada air baku, 330 partikel pada air dari tangki penampungan, dan 111 partikel pada AMDK. Bentuk yang paling dominan secara keseluruhan adalah film sebanyak 268 partikel, sedangkan warna dominan adalah cokelat sebanyak 236 partikel. Kelimpahan mikroplastik pada air baku sebesar 47.55 partikel/L, air dari tangki penampungan sebesar 110.00 partikel/L, dan AMDK sebesar 24.67 partikel/L. Hasil penelitian menunjukkan bahwa mikroplastik masih ditemukan pada seluruh tahapan, dengan kelimpahan tertinggi pada air dari tangki penampungan dan terendah pada produk AMDK.
Abstract: Bottled Drinking Water (BDW) has the potential to contain microplastics originating from raw water sources as well as from treatment processes, making it necessary to examine changes in their characteristics through to the final product. This study aimed to analyze the number, shape, color, and abundance of microplastics in raw water, water from the storage tank, and bottled drinking water sourced from the Gunung Palung spring in Sukadana District. The study consisted of three sample types, each analyzed in triplicate. Raw water samples were analyzed through organic matter degradation using the Wet Peroxide Oxidation method, density separation using NaCl, filtration with Whatman No. 42 filter paper, and microscopic observation. Water from the storage tank and bottled drinking water samples were directly subjected to filtration and microscopic observation. Microplastics were identified in all samples, with 126 particles in raw water, 330 particles in water from the storage tank, and 111 particles in bottled drinking water. The most dominant microplastic shape overall was film, with 268 particles, while the most dominant color was brown, with 236 particles. Microplastic abundance increased from 47.55 particles/L in raw water to 110 particles/L in water from the storage tank, then decreased to 24.67 particles/L in bottled drinking water. This pattern indicates changes in the number and characteristics of microplastics throughout the treatment process, with the highest abundance found in water from the storage tank and the lowest in the final bottled drinking water product.
