Air pollution is one of the environmental problems that can have serious impacts on humans and the environment. To prevent these negative impacts from spreading, environmental monitoring efforts can be carried out periodically. The existing monitoring methods basically use chemical methods that are destructive. Therefore, the development and use of fast and non-destructive methods is a much-needed innovation. One of the alternative methods that are expected to be such an innovation is the rock magnetization method. Magnetic rocks have been used to assess climate and environmental changes. The application of this method has been used in the field of biomagnetism or the study of magnetism in living things through the presence of magnetic minerals based on the type, grain size, grain shape, and morphology. This article is an overview of the use of rock magnetization methods to characterize leaves as receptors for atmospheric pollutants.

Activities along the Krueng Aceh river such as port activities, fisheries, ship breeding, tourist attractions, market activities and settlements cause a lot of domestic waste in the environment around the river and affect river clarity and increase the concentration of turbidity. High turbidity in rivers can affect the entry of light into the waters because light has an important role in the photosynthesis process. The method of monitoring water quality can be done by remote sensing because it has several advantages such as being able to carry out measurements on a larger scale for a long time, relatively quickly, and reducing the amount of costs incurred. Monitoring the Krueng Aceh River is carried out using remote sensing technology using Sentinel-2 imagery. This study aims to obtain the value of the distribution of turbidity by analyzing satellite imagery and its correlation with rainfall, and to determine the value of the distribution of turbidity, Total Suspended Solid (TSS), Total Dissolved Solid (TDS), and Power of Hydrogen (pH) in the Krueng Aceh River. The results showed that sentinel-2 image analysis got the lowest turbidity on September 6, 2021, which was -0.992424, and the highest on October 5, 2019 which was 0.248641. The distribution of water quality is known to have the highest turbidity concentration obtained at sampling location point 1, which was 107.9 NTU. The highest concentration of TSS was found at sampling locations 1, 4, and 7, which was 400 mg/l. The highest TDS concentration was found at point location 1, which was 1,413 mg/l. The pH concentration at the Krueng Aceh River sampling location has met the quality standards set in PP No. 82 of 2021

Metode Multi Soil Layering (MSL) adalah metode pengolahan limbah yang memanfaatkan tanah sebagai media dalam penyisihan parameter. Metode MSL sudah banyak digunakan pada berbagai pengolahan limbah cair seperti limbah cair domestik, industri dan lain sebagainya. Namun, belum pernah ditemukan publikasi pengolahan limbah cair industri pembekuan ikan dengan menggunakan metode MSL. Oleh karena itu penelitian ini bertujuan untuk mendapatkan efektivitas metode MSL dalam menurunkan parameter Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) dan pH pada limbah cair industri pembekuan ikan. Variasi yang digunakan pada penelitian ini adalah variasi 1, 2 dan 3 layer SMB. Penelitian ini menggunakan variasi waktu pengolahan 24, 48 dan 72 jam. Pengolahan limbah cair industri pembekuan ikan menggunakan metode MSL dapat menurunkan kadar COD, TSS, dan menetralkan pH. Hasil dari pengolahan limbah cair industri pembekuan ikan menggunakan metode MSL pada parameter COD senilai 41 mg/l dengan efektivitas penurunannya 90,33%, parameter TSS senilai 49 mg/l dengan efektivitas penurunannya 88,94%, dan mengalami perubahan nilai pH menjadi 7,7 pada variasi 1 layer SMB dengan waktu 72 jam. Metode MSL diharapkan menjadi sebuah alternatif baru pada pengolahan limbah cair industri pembekuan ikan sehingga dijadikan metode dalam mengolah limbah cair yang dihasilkan.

Oil waste that enters the soil will cause damage to the soil. Bioremediation is an alternative to hazardous waste treatment which is relatively more economical, easy and environmentally friendly. This technology utilizes microbial activity to treat polluted soil. Cow dung is an organic material that contains many microbes and also contains good nutrition for microbial growth. Cow dung contains several microorganisms such as bacteria (Bacillus sp, Lactobacillus sp and Corynebacterium sp), fungi (Trichoderma sp and Aspergillus sp), protozoan and yeast species (Candida sp and Saccharomyces sp). Cow dung in this study acts as a bioactivator and a source of nutrients for microbes in degrading Total Petroleum Hydrocarbon (TPH) in oil-contaminated soil. This study aims to determine the effect of adding cow dung on bioremediation of oil-contaminated soil. This study consisted of six (6) treatments, namely the concentration of cow dung with variations in concentrations of 0 gr, 20 gr, 40 gr, 60 gr, 80 gr, and 100 gr on each soil of 300 gr and processing time for 30 days and analyzed 2 times a day. In this study, measurements of pH and TPH values were carried out. The results of the analysis showed that the addition of cow dung with a concentration of 100 gr on 300 gr of soil was able to reduce the TPH value from 3.6% to 0.2%, with the effectiveness of reducing TPH by 86.66% within 30 days. Based on the results of the analysis using the Simple Linear Regression Test, it was stated that the bioremediation time and the addition of the concentration of cow dung had an effect on the decrease in the TPH value.

Indonesia saat ini memiliki kapasitas produksi tahu 2,56 ton/tahun. Limbah cair tahu yang dialirkan langsung ke saluran pembuangan tanpa di olah terlebih dahulu akan menjadi masalah bagi lingkungan. Salah satu teknik pengolahan air limbah adalah dengan menggunakan trickling filter dengan media bioball. Penelitian ini bertujuan untuk mengolah limbah cair tahu dengan trickling filter menggunakan media bioball. Sampel limbah cair tahu sebanyak 40 Liter, di peroleh dari Desa Sukaramai, Kecamatan Baiturrahman, Kota Banda Aceh. Penurunan konsentrasi limbah cair diamati melalui parameter nilai COD, pH dan TSS dan pengukuran total koloni pada biofilm. Eksperimen dilakukan dengan variasi jumlah media bioball sebanyak 50, 100 dan 150 bioball dan variasi waktu 8, 24, 72 dan 168 jam. Pada pengukuran COD dengan variasi 150 bioball menggunakan waktu 168 jam didapatkan penurunan yang signifikan yaitu sebesar 78,79%. Sementara, pada pengukuran TSS dengan variasi 150 bioball menggunakan waktu 168 jam didapatkan hasil penurunan sebesar 75,93%. Sedangkan untuk eksperimen peningkatan pH didapatkan hasil yaitu sebesar 8,3. Hasil penelitian menunjukan bahwa variasi jumlah media bioball dan variasi waktu mempengaruhi proses degradasi dalam reaktor trickling filter dan telah memenuhi standar baku mutu sesuai dengan peraturan Menteri Lingkungan Hidup Republik Indonesia Nomor 5 Tahun 2014. Serta, hasil total koloni bakteri yang didapatkan pada variasi 150 bioball selama 28 hari yaitu 6,2×105 Cfu/ml menunjukkan bahwa semakin lama masa inkubasi biofilm dapat mempercepat laju degradasi terhadap parameter COD, TSS, dan pH pada limbah cair tahu.

Abstract: Indonesia has a very large number of watersheds and has a very diverse size. Damage to several watersheds in Indonesia has also occurred and often results in catastrophic floods and droughts that threaten people. The presence of the RRI Model with its capabilities will help contribute to watershed management in order to solve water resource problems. The RRI model is a two-dimensional (2D) model capable of simulating runoff, rainfall, and flood inundation simultaneously. The use of this model in Indonesia has reached 13 times which was compiled based on the number of publications on the application of the RRI model. All of these publications have passed peer-reviewed papers from both journals and conference papers. Applications have been made in several places including the Solo watershed, the Upper Citarum watershed, the Batanghari watershed, and the upstream Brantas watershed. Given the increasing number of problematic watersheds in Indonesia, the use of this model has the prospect and relevancy of being carried out in other watersheds. However, until now, researchers have had challenges in building hydrological models because of the constraints on the availability of climatological and hydrological data in the watershed. Therefore, in addition to improving the data measuring infrastructure in the field, remote sensing techniques are also needed in an effort to generate targeted watershed information. In fact, the effort to utilize remote sensing in generating unmeasurable data in the field has been successfully conducted in several studies.Abstrak: Indonesia memliki jumlah DAS yang sangat banyak dan memiliki ukuran yang sangat beragam. Kerusakan beberapa DAS di Indonesia juga telah terjadi dan sering berakibat bencana banjir dan kekeringan yang mengancam penduduk setempat. Kehadiran Model RRI dengan kemampuannya akan membantu berkontribusi dalam memajemen DAS ataupun dalam usaha untuk menyelesaikan permasalahan sumberdaya air. Model RRI adalah suatu model dua dimensi (2D) yang memiliki kemampuan untuk mensimulasikan limpasan curah hujan dan genangan banjir secara simultan. Penggunaan model RRI ini di Indonesia telah mencapai 13 kali, yang tercatat berdasarkan jumlah publikasi yang terkait dengan aplikasi model RRI. Semua publikasi tersebut telah melewati peer-review baik dari jurnal maupun dari konferensi. Aplikasi telah dilakukan dibeberapa tempat termasuk DAS Solo, DAS Citarum, DAS Batanghari, dan DAS Brantas. Mengingat jumlah DAS yang bermasalah di Indonesia semakin meningkat, maka penggunaan model ini memiliki prospek untuk dilakukan di DAS lain. Namun sampai saat ini, para peneliti memiliki tantangan dalam membangun permodelan hidrologi karena terkendala pada ketersediaan data klimatologi dan hidrologi di dalam DAS. Oleh karena itu, selain peningkatan infrastruktur pengukur data dilapangan dan teknik pengindraan jauh juga diperlukan dalam usaha menyediakan informasi DAS yang ditargetkan. Usaha penggunaan teknik pengindraan jauh dalam menyediakan data yang tidak terukur dilapangan telah sukses dan terbukti dilakukan di beberapa studi.

The Company's input pipes contained microplastics, per the preliminary test findings. While the water yield produced by PDAM Tirta Daroy contains 150 particles/L, the Tirta Daroy Drinking Water Area has 275 particles/L. Microplastics found in the water pose a major risk to living beings if they are consumed. This work aims to characterize the properties, flux, and polyethersulfone (PES) membrane rejection coefficient, which were made utilizing the phase inversion technique with a solvent and additives called N,N-dimethylformamide (DMF). In Sungai Krueng Aceh, titanium dioxide (TiO2) is utilized to filter out microplastics from the water. Results of Scanning Electron Microscopy (SEM) examination of Membrane Morphology demonstrate that the resulting membrane is an asymmetrical membrane of two layers, the upper layer relatively thin and the lower layer porous. When compared to the PES membrane when it was 15% DMF/TiO2, the 20% DMF/TiO2 membrane exhibits a finger-like cross-sectional structure called a macrovoid) with more and larger numbers. Analysis of the microplastic rejection coefficients proved the effectiveness of PES, DMF, and TiO2 membranes in removing microplastics. Results of tests on the effectiveness of rejecting microplastics after undergoing process filtration with a microplastic rejection coefficient of 94% and 14.2 particles/L utilizing a 20% PES/DMF/TiO2 membrane Performance of PES membranes: The PES membrane with 20% DMF/TiO2 has a water flux of 0.467 L/m2.hour compared to 15% DMF/TiO2 0.733 L/m2.hour. This study's findings on membrane Ultrafiltration have the potential to be used as a water filter standard in PDAM.
