Abstract

Abstract: The increasing use of cosmetics and personal care products containing small-sized and low-density microbeads will disrupt the aquatic environment because they are difficult to remove in wastewater treatment plants (WWTPs). Electrocoagulation (EC) is an effective technology for removing microbeads from greywater. This research aims to develop an effective cylindrical electrode geometry design in the EC process to reduce electrode passivation, as evidenced by the removal of polyethylene (PE) microbeads from greywater, reduced energy consumption, and the analysis of the EC kinetics model. Experiments were carried out on batch and continuous systems using artificial greywater with an initial concentration of 0.5 g/L. Variations made in the batch system are the geometry of the cylindrical electrode without holes (ESTB), a cylindrical electrode with holes (ESB), a cylindrical electrode with anode with holes, and a cathode with no holes (ESB-A), a cylindrical electrode with cathode, with holes and anode with no holes (ESB-K), and plate electrode (EP). The variations carried out in the continuous system were flow rates of 60, 70, 80, and 90 mL/minute using the best electrode geometry design obtained from the batch system. The best removal efficiency of PE microbeads in a batch system was 98.44% in ESB-K geometry and saved 75% energy consumption compared to EP. The best removal efficiency of PE microbeads in a continuous system was 79.76% at a flow rate of 60 mL/minute. The kinetic model of the EC reaction which corresponds to the removal process of PE microbeads is a first-order reaction. Future research should focus on optimizing the design of continuous reactors so that they can be applied to tertiary processing in domestic WWTPs and industrial WWTPs.Abstrak: Meningkatnya penggunaan kosmetik dan produk perawatan pribadi (CPCP) yang mengandung microbeads berukuran kecil dan berkepadatan rendah akan mengganggu lingkungan perairan karena sulit disisihkan di instalasi pengolahan air limbah (IPAL). Elektrokoagulasi adalah teknologi yang efektif untuk menyisihkan microbeads dari greywater. Penelitian ini bertujuan untuk mengembangkan desain geometri elektroda silinder yang efektif pada proses elektrokoagulasi untuk mengurangi pasivasi elektroda yang dibuktikan dari penyisihan microbeads polyethylene dari greywater dan pengurangan konsumsi energi yang digunakan dan menganalisis model kinetika elektrokoagukasi. Eksperimen dilakukan pada sistem batch dan kontinu menggunakan greywater artifisial dengan konsentrasi awal 0,5 g/L. Variasi yang dilakukan pada sistem batch adalah geometri elektroda silinder tidak berlubang (ESTB), elektroda  silinder  berlubang (ESB), elektroda silinder anoda berlubang dan katoda  tidak  berlubang (ESB-A), elektroda  silinder  katoda  berlubang  dan  anoda  tidak  berlubang (ESB-K), dan elektroda pelat (EP). Variasi yang dilakukan pada sistem kontinu adalah laju alir 60, 70, 80, dan 90 mL/menit menggunakan desain geometri elektroda terbaik yang diperoleh dari sistem batch. Efisiensi penyisihan microbeads polyethylene terbaik pada sistem batch sebesar 98,44% pada geometri ESB-K dan menghemat 75% konsumsi energi dibandingkan EP. Efisiensi penyisihan microbeads polyethylene terbaik pada sistem kontinu sebesar 79,76% pada laju alir 60 mL/menit. Model kinetika reaksi elektrokoagulasi yang sesuai dengan proses penyisihan microbeads polyethylene adalah reaksi orde satu. Penelitian selanjutnya harus berfokus pada optimalisasi desain reaktor kontinu, sehingga dapat diterapkan pada pengolahan tersier di IPAL domestik maupun IPAL industri.

Abstract

Abstract: Microplastics have become a global concern due to their wide distribution and ecological effects. Understanding the interactions between microplastics and ecosystems is important for environmental risk assessment. This study analyzed the abundance and distribution of microplastics in Lake Singkarak. Substantial microplastic research is still lacking for freshwater biota, so a study was conducted to determine the level of microplastic pollution in bilih fish tissue. The fish's size, weight, and sampling point were studied about microplastic uptake through two channels, digestion and respiration. From the results, the types of polymers identified in this study were polyethylene, polyvinyl chloride, and polyethylene terephthalate. Overall, 7.14% - 23.53% (average = 11.48%) of microplastics were identified in the D tract of bilih fish from sixteen different sampling points. While 7.69% - 17.39% (average = 11.85%) of microplastics were identified in the respiration of bilih fish. The highest percentage of the abundance of microplastic forms in the digestions identified was fiber at 70.42% and 66.82% in the digestions. At the same time, The lowest percentage identified was fragmented, with an average abundance of 29.58% in digestion and 33.32% in respiration. In conclusion, this study reveals the presence and impact of microplastics in Lake Singkarak, West Sumatra, on the bilih fish (Mystacoleucus padangensis). By examining the fish's digestive and respiratory systems and using FT-IR Spectroscopy, the research highlights the ecological and economic implications of microplastic pollution. These findings emphasize the need for targeted conservation and management strategies.Abstrak: Mikroplastik telah menjadi perhatian global karena distribusinya yang luas dan efek ekologisnya. Pemahaman tentang interaksi antara mikroplastik dengan ekosistem dinilai penting untuk penilaian risiko lingkungannya. Penelitian ini menganalisis kelimpahan dan distribusi mikroplastik di Danau Singkarak. Penelitian mikroplastik secara substansial masih sedikit untuk biota air tawar maka dilakukan penelitian untuk menentukan tingkat polusi mikroplastik pada jaringan ikan bilih. Ukuran, berat, dan titik sampling ikan diteliti dalam kaitannya dengan jerapan mikroplastik melalui dua saluran, yaitu digestif (pencernaan) dan respirasi (pernapasan). Dari hasil penelitian, jenis polimer yang teridentifikasi dalam penelitian ini adalah jenis polietilen, polivinil klorida, dan polietilen tereftalat. Secara keseluruhan 7,14% - 23,53% (rata-rata = 11,48%) mikroplastik teridentifikasi pada digestif ikan bilih dari enam belas titik sampling yang berbeda. Sementara 7,69% - 17,39% (rata-rata = 11,85%) mikroplastik teridentifikasi pada respirasi ikan bilih. Persentase kelimpahan bentuk mikroplastik tertinggi pada digestif yang diidentifikasi adalah fiber sebesar 70,42% dan 66,82% pada digestif. Sementara persentase terendah yang diidentifikasi adalah fragment dengan rata-rata kelimpahan sebesar 29,58% di digestif dan 33,32% di respirasi. Sebagai kesimpulan, penelitian ini mengungkap keberadaan dan dampak mikroplastik di Danau Singkarak, Sumatera Barat, pada ikan bilih (Mystacoleucus padangensis). Dengan memeriksa sistem pencernaan dan pernapasan ikan serta menggunakan Spektroskopi FT-IR, studi ini menunjukkan implikasi ekologis dan ekonomi dari polusi mikroplastik. Temuan ini menekankan perlunya strategi konservasi dan pengelolaan yang terarah.

Abstract

The purpose of this study is to identify factors that affect environmental parameters in sediments and their impact on sewage treatment plant in Padang city in order to become a basic scientific reference in effective and sustainable water resources management. The measurements were carried out at 5 artificial system locations, namely the Rubber Factory Wastewater Treatment Plant (WWTP), Tofu Factory wastewater drainage, WWTP of Teaching Hospital Andalas University, Fecal Sludge Treatment Plant, and Leachate Treatment Plant at the Air Dingin of Landfill in Padang City, West Sumatra. The measured water parameters are pH, temperature, and salinity, while the measured sediments are nitrite and nitrate. Analysis of environmental parameters in the waters were temperature (30 - 34°C), pH (5.5 - 6.8), and salinity (0 ± 0.4 ppt). The results obtained in the sediment were nitrite (0.63 - 153.58 mg/L), and nitrate (19.28 - 50.01mg/L). Factors that affect water and sediment parameters are biological activity and anthropogenic contaminants. One of the causes of high concentrations of environmental parameters in sediments is the ability of sediments to accumulate and absorb particles and chemicals.
