Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh jumlah pelat elektroda Fe-Al pada pengurangan mikroplastik dalam limbah masker secara elektrokoagulasi. Sampel penelitian adalah limbah masker medis. Masker dipotong-potong dengan ukuran 1-5 mm. Potongan masker tersebut direndam dalam aquades selama 7 hari. Cairan yang mengandung mikroplastik dielektrokoagulasi dengan kombinasi pelat elektroda (Al-Fe), (Al-Fe-Al), dan (Al-Fe-Al-Fe) selama 4 jam, arus listrik 2,5 A dan pH 6,0. Serat mikroplastik sebelum dan sesudah elektrokoagulasi diamati dengan mikroskop perbesaran 40 kali. Karakterisasi mikroplastik dilakukan dengan menggunakan FTIR (Fourier Transform Infra Red) dan SEM (Scanning Electron Microscope). Hasil penelitian menunjukkan bahwa efektifitas pengurangan mikroplastik yang dielektrokoagulasi menggunakan kombinasi pelat elektroda (Al-Fe), (Fe-Al-Fe), (Al-Fe-Al-Fe) berturut-turut adalah 82,5; 87,5; dan 90,0%. Semakin banyak jumlah pelat pada elektrokoagulasi mikroplastik dapat meningkatkan efektifitas pengurangan mikroplastik. Gugus fungsi yang terkandung dalam masker sebelum dan sesudah elektrokoagulasi mempunyai kemiripan dengan flok yang dihasilkan. Gumpalan Flok hasil elektrokoagulasi berbentuk variatif dan terdapat serat.Kata kunci: elektroda, elektrokoagulasi, masker, mikroplastik, pelat Fe-Al Application of variation in Al-Fe electrode plates to reduce microplastics in masks waste by electrocoagulationAbstract: This study investigates how the number of Fe-Al electrode plates affects electrocoagu-lation's effectiveness in decreasing mask waste microplastics. The sample in this study was medical mask waste. The mask is chipped into 1-5 mm pieces. The pieces of the mask are soaked in distilled water for seven days. Liquid-containing microplastics were electrocoagulated with a combination of Fe-Al, Fe-Al-Fe, and Fe-Al-Fe-Al electrode plates for 4 hours at an electric current of 2.5 A and a pH of 7.0. Microplastic fibers before and after electrocoagulation were observed with a forty-fold magnification microscope. Microplastic characterization was carried out using FTIR (Fourier Transform Infra Red) and SEM (Scanning Electron Microscope). The results showed that the effectiveness of electrocoagulation microplastics using a combination of electrode plates (Fe-Al), (Fe-Al-Fe), and (Fe-Al-Fe-Al) was 82.5, 85.0, and 87.5%, respectively. The efficiency of microplastic reduction can be improved by using more plates in microplastic electrocoagulation. The functional groups contained in the masks before and after electrocoagulation are similar to the flocs produced. Floc clumps resulting from electrocoagulation are varied in shape and contain fibers.Keywords: electrocoagulation, electrode, face mask, microplastic

Abstract

Tujuan penelitian ini untuk mengetahui karakter gugus fungsi masker bedah medis sebelum dan sesudah pelepasan mikroplastik, karakter flok ditinjau dari gugus fungsi dan kenampakan butiran flok dan pengaruh volume Na2SO4 0,01 M, pH dan waktu elektrokoagulasi terhadap efektivitas pengurangan konsentrasi mikroplastik dalam limbah masker bedah medis. Sampel penelitian ini adalah limbah masker bedah medis yang diambil mikroplastiknya dengan cara direndam dalam aquabidest selama ± 50 hari. Identifikasi mikroplastik dengan menganalisis spektrum FTIR. Elektrokoagulasi menggunakan elektroda Al-Fe-Al, arus 2,5 A dan jarak antar elektroda 2 cm dengan variasi volume Na2SO4 0,01 M, pH larutan dan waktu elektrokoagulasi. Efektivitas pengurangan konsentrasi mikroplastik setiap variasi dihitung dengan membandingkan jumlah serat sebelum dan sesudah elektrokoagulasi. Morfologi flok ditentukan dengan menganalisis kenampakan permukaan flok menggunakan SEM dan gugus fungsi flok menggunakan FTIR. Hasil penelitian menunjukkan bahwa karakterisasi menggunakan FTIR masker medis sebelum dan sesudah pelepasan mikroplastik serta flok terdapat gugus fungsi yang sama yaitu pada bilangan gelombang 611 cm-1 menunjukkan adanya serapan vibrasi fenil yang memperlihatkan bahwa terkandung monomer polipropilena (PP) dan bilangan gelombang 1165 cm-1 menunjukkan adanya gugus C-Cl yang memperlihatkan bahwa terkandung monomer polivinil klorida (PVC). Hasil SEM menunjukkan bahwa flok berbentuk serbuk berwarna putih dengan butiran flok renggang dan tidak kompak. Volume Na2SO4 0,01 M optimum 1 mL, pH optimum 6 dan waktu elektrokoagulasi optimum 4 jam dengan efektivitas pengurangan konsentrasi mikroplastik dalam limbah masker bedah medis sama yaitu 87,5%.

Abstract

Karangmalang and Kuningan are the area located near the campus ofYogyakarta State University and Gadjah Mada University. This causes the twoareas have crowded population. Many students from outside of Sleman Yogyakarta stay in many boarding houses that need laundry service since they do not have enough time and are very busy of studying activities. There are approximately 30 laundry service businesses in these areas. The condition has positive impact on local people income generating. However, it also cause adverse effects on the environment because of the laundry waste water directly discharged into the environment without prior treatment. The priority problem to solve is the disposal of waste water and dissemination of eco-friendly detergen. We had "Sekar Laundry" and "Ramadhani Laundry"as our partners in this programme. To achieve the objectives of the project we carried out the following methods: (1) socialization, counseling, and training for the introduction of ecofriendly detergents and simple sewage treatment; and (2) the application of appropriate technology of waste water treatment based on fitoremediation for both partners. The results obtained were in accordance with the purposes. We could overcome the environmental pollution caused by waste water of laundry activities. Based on laboratory tests, laundry waste water from the outlet of the Waste Water Treatment Plant (the WWTP) had significantly quality improvement that it made safer to be discharged into the environment, with 27,125% of BOD decline efficiency, 120,350% of COD decline efficiency, 17,300% of TSS decline efficiency, 11,597% of detergent decline efficiency, and 88% of phosphate decline efficiency
