Abstract

Sampah Kota Mojokerto yang berasal dari berbagai sumber diangkut dan ditimbun di TPA Randegan, Kota Mojokerto. Di TPA terjadi proses degradasi dan fragmentasi plastik menjadi mikroplastik (MP). Peristiwa tersebut menyebabkan lindi terkontaminasi MP. TPA Randegan telah dilengkapi dengan instalasi pengolahan lindi (IPL) yang terdiri dari 8 unit, yaitu: bak inlet, bak ekualisasi, bak aerasi, bak pengendap 1, bak pengendap 2 (2 unit), bak pengendap 3, dan bak outlet. Penelitian ini bertujuan untuk menentukan kelimpahan dan karakteristik (ukuran, bentuk, jenis polimer, dan warna) dan sebaran MP pada unit-unit pengolahan dan efluen IPL, serta efisiensi penyisihannya. Sampling dilakukan secara grab pada bagian influen dan efluen setiap unit-unit pengolahan, serta pada efluen IPL. Jumlah lokasi sampling pada penelitian ini adalah 2 lokasi. Sampling dilakukan dengan dua kali pengulangan yaitu pada tanggal 13 dan 20 Maret 2022 pukul 09.00 – 11.30. Pengambilan sampel dilakukan dengan menggunakan alat sampler berukuran 5 L. Ekstraksi MP dilakukan menggunakan metode Wet Peroxide Oxidation (WPO) lalu disaring menggunakan filter dan membran PTFE. Kemudian MP diamati dan disortasi menggunakan dissecting microscope (1-1200X digital microscope HD 7 inch LCD screen 12 megapixels dan Dino Capture 2.0) dengan pembesaran 40× – 60×, sedangkan identifikasi jenis polimer MP menggunakan Thermo ScientificTM NicoletTM iSTM 10 FTIR Spectrometer. Kelimpahan MP pada proses pengolahan air lindi di IPL TPA Randegan menurun dari 9,00 ± 0,85 partikel/L di inlet menjadi 2,20 ± 0,28 partikel/L pada efluen. Bentuk MP didominasi oleh bentuk fiber yaitu sebesar 78,55% dan fragmen sebesar 17,86%. Warna MP didominasi oleh warna hitam sebesar 66,91% dan warna merah sebesar 14,92%. Ukuran MP didominasi dengan ukuran 101 μm – 350 μm sebesar 37,51% dan 1 μm – 100 μm sebesar 30,58%. Jenis polimer yang ditemukan pada sampel adalah bakelit, cellophane, polyethylene (PE), polyvinylidene fluoride (PVDF), polyamide (PA), polystyrene (PS), polypropylenesulfide (PPS), polycarbonate (PC), polyethyleneterephthalate (PET) dan polyacrylate. Kelimpahan MP mengalami fluktuasi pada bak aerasi menuju bak pengendap 1. Unit IPL yang dapat menurunkan kelimpahan MP adalah bak ekualisasi (10%-16%), bak pengendap 1 (29%), bak pengendap 2A (8%-13%), bak pengendap 2B (9%-15%), bak pengendap 3 (27%-30%), total bak sedimentasi (59% - 62%), dan bak outlet (25%-29%). Total penyisihan MP pada IPL TPA Randegan adalah 75%-76%.

Mojokerto City waste originating from various sources is transported and stored at the Randegan Landfill, Mojokerto City. In the landfill, there is a process of degradation and
fragmentation of plastic into microplastic (MP). This incident caused the leachate to be contaminated with MP. Randegan Landfill has been equipped with a leachate treatment plant which consists of 8 units, namely: inlet tank, equalization tank, aeration tank, settling tank 1, settling tank 2 (2 units), settling tank 3, and outlet tank. This study aims to determine the characteristics (size, shape, polymer, and color) and distribution of MP in leachate processing units and treatment plant (LTP) effluent, as well as their removal efficiency. Samples were collected from influent and effluent sections of each processing unit, as well as from the LTP effluent. The number of sampling in this study were 2 locations. Sampling was carried out twice, namely on 13 and 20 March 2022 at 09.00 – 11.30. The sample was taken using a 5 L sampler. The MP was extracted out using Wet Peroxide Oxidation (WPO) and filtered using PTFE membrane. Then MP was observed and sorted using a dissecting microscope (Sunshine SZM45T-B1 and Dino Capture 2.0) with 40× – 60× facilities. While the type of polymer MP uses a Thermo ScientificTM NicoletTM iSTM 10 FTIR Spectrometer. The abundance of MP in the leachate treatment process at IPL TPA Randegan decreased from 9.00 ± 0.85 particles/L at the inlet to 2.20 ± 0.28 particles/L in the effluent. The MP form is dominated by the fiber form, which is 78.55% and the fragment is 17.86%. MP color is dominated by black by 66.91% and red by 14.92%. The size of the MP is dominated by the size of 101 μm – 350 μm by 37.51% and 1 μm – 100 μm by 30,51%. The types of polymers found in the samples were bakelite, cellophane, polyethylene (PE), polyvinylidene fluoride (PVDF), polyamide (PA), polystyrene (PS), polypropylenesulfide (PPS), polycarbonate (PC), polyethyleneterephthalate (PET), and polyacrylate. The abundance of MP fluctuated in the aeration tank to the settling tank I. The IPL units that could reduce MP were equalization tank (10%-16%), settling tank 1 (29%), settling tank 2A (8%-13%), settling tank 2B (9%-15%), settling tank 3 (27%-30%), total settling tank (59% - 62%), and outlet tank (25%-29%). Total MP allowance for Randegan Landfill is 75%-76%.
