Abstract

IPAM Tegal Besar PDAM Tirta Pandalungan Kabupaten Jember menyediakan kebutuhan air bersih bagi masyarakat Jember. IPAM Tegal Besar mengambil air Sungai Bedadung sebagai air baku. Air Sungai Bedadung mengalami penurunan kualitas akibat pembuangan sampah plastik ke sungai. Plastik yang berukuran besar dapat terdegradasi menjadi mikroplastik. Penelitian ini bertujuan untuk menghitung kelimpahan dan mengidentifikasi karakteristik mikroplastik pada air dan lumpur hasil pengolahan IPAM Tegal Besar serta mengevaluasi penyisihan mikroplastik pada unit koagulasi-flokulasi-sedimentasi, unit filtrasi, dan unit desinfeksi IPAM Tegal Besar PDAM Kabupaten Jember. Penelitian ini dilakukan terhadap air dan lumpur dari unit-unit operasi IPAM Tegal Besar yang terdiri atas unit intake, inlet unit flokulasi, outlet unit sedimentasi, outlet unit filtrasi, inlet unit reservoir, saluran lumpur backwash, dan saluran lumpur sedimentasi. Pengambilan sampel dilakukan dengan menggunakan metode komposit lokasi dan komposit waktu. Ekstraksi sampel mikroplastik menggunakan hidrogen peroksida dan larutan NaCl. Partikel mikroplastik dipisahkan secara manual, diamati, dan disortasi menggunakan mikroskop digital untuk menganalisis kelimpahan dan karakteristik mikroplastik. Jenis polimer mikroplastik ditentukan dengan FTIR. Kelimpahan mikroplastik pada air baku IPAM Tegal Besar PDAM Kabupaten Jember sebanyak 10-17 partikel/L dan mengalami penurunan akibat adanya pengolahan pada unit koagulasi-flokulasi-sedimentasi, unit filtrasi, dan unit desinfeksi menjadi 4-5 partikel/L di air produksi dengan efisiensi penyisihan mikroplastik total sebesar 60-70,6%. Sedangkan pada lumpur backwash ditemukan mikroplastik sebanyak 4-12 partikel/L dan pada lumpur sedimentasi ditemukan mikroplastik sebanyak 5-10 partikel/L. Karakteristik mikroplastik yang diamati berupa bentuk, warna, dan ukuran. Bentuk mikroplastik baik pada air baku, air hasil pengolahan, dan lumpur hasil pengolahan IPAM Tegal Besar didominasi oleh filamen/fiber seebsar 50-86%. Warna mikroplastik yang paling banyak ditemukan adalah warna hitam sebesar 60-86%. Sedangkan ukuran mikroplastik pada air dan lumpur didominasi oleh ukuran 51 μm-100 μm sebesar 23-100%. Jenis mikroplastik yang ditemukan seluruhnya berjenis LDPE atau Low Density Polyethylene.

The Tegal Besar Water Treatment Plant of PDAM Tirta Pandalungan Jember provides clean water for the people of Jember. Tegal Besar Water Treatment Plant takes water from Bedadung River as raw water. Bedadung River water quality has decreased due to plastic waste disposal into the river. Large plastic can be degraded into microplastics. This study aims to calculate the abundance and identify the characteristics of microplastics in water and sludge from the Tegal Besar Water Treatment Plant and evaluate the removal of microplastics in the coagulation-flocculation-sedimentation unit, filtration unit, and disinfection unit of the Tegal Besar Water Treatment Plant of PDAM Jember. This study was conducted on water and sludge from the Tegal Besar Water Treatment Plant operating units consisting of the intake unit, flocculation unit inlet, sedimentation unit outlet, filtration unit outlet, reservoir unit inlet, backwash sludge channel, and sedimentation sludge channel. Sampling was conducted using location composite and time composite methods. Extraction of microplastic samples using hydrogen peroxide and NaCl solution. Microplastic particles were manually separated, observed, and sorted using a digital microscope to analyze the abundance and characteristics of microplastics. The polymer type of microplastics was determined by FTIR. The abundance of microplastics in the raw water of the Tegal Besar Water Treatment Plant of the Jember Regency PDAM was 10-17 particles/L and decreased due to treatment in the coagulation-flocculation-sedimentation unit, filtration unit, and disinfection unit to 4-5 particles/L in production water with a total microplastic removal efficiency of 60-70.6%. Meanwhile, in the backwash sludge, microplastics were found to be 4-12 particles/L and in the sedimentation sludge, microplastics were found to be 5-10 particles/L. The characteristics of microplastics observed are shape, color, and size. The shape of microplastics in both raw water, treated water, and sludge from the Tegal Besar Water Treatment Plant is dominated by filaments/fiber as much as 50-86%. The most common color of microplastics is black at 60-86%. While the size of microplastics in water and sludge is dominated by the size of 51 μm�100 μm by 23-100%. The types of microplastics found were all LDPE or Low Density Polyethylene
