Kehadiran telur cacing parasit di lingkungan menjadi perhatian sejak badan kesehatan dunia (WHO) mempublikasikan versi baru dari Pedoman untuk Penggunaan Kembali Air Limbah, Materi Fekal, dan Greywater untuk Pertanian dan Perairan tahun 2006 yang menjadikan telur cacing parasit sebagai polutan yang perlu mendapat perhatian. Batas ekuivalen telur cacing dalam lumpur adalah kurang dari 1 telur/gram total solid (TS). Telur cacing parasit, khususnya nematode Ascaris spp., menjadi ancaman dalam pemanfaatan air limbah dan lumpur sebagai produk sampingan Instalasi Pengolahan Air Limbah Domestik (IPALD) karena sifatnya yang resisten menyebabkan waktu ketahanan telur cacing lebih panjang dibandingkan mikroorganisme lain. Penelitian ini bertujuan untuk mengetahui jumlah telur cacing Ascaris spp. pada air limbah dan lumpur IPALD. Sampel air limbah dan lumpur diambil dari kolam anaerobic, fakultatif, dan maturasi IPAL Bojongsoang, Bandung. Metode deteksi dan kuantifikasi menggunakan prinsip pencucian, flotasi dan sedimentasi. Hasil penelitian ini adalah ditemukan telur cacing Ascaris spp. baik bentuk fertile maupun infertile di semua sampel dengan jumlah telur fertile lebih banyak dibandingkan bentuk infertile. Pada lumpur kolam anaerobic, fakultatif, dan maturasi jumlah telur Ascaris spp. fertile berturut-turut adalah 202, 40, dan 39 telur/gram sedangkan telur Ascaris spp. infertile adalah 82, 22, dan 27 telur/gram. Pada air inlet, kolam anaerobic, fakultatif, dan maturasi jumlah telur Ascaris spp. fertile berturut-turut adalah 3662, 1187, 613, dan 342 telur/liter sedangkan telur Ascaris spp. infertile adalah 1227, 333, 240, dan 280 telur/liter. Jumlah ini menunjukkan resiko tinggi pencemaran badan air dan daerah pertanian serta ancaman bagi kesehatan masyarakat di sekitar IPAL.

Introduction: Ascaris spp. eggs threaten sludge reuse because they are usually more environmentally resistant than other microorganisms. Consequently, the WHO recommended an acceptable limit of <1 helminth egg per gram of total solid as a health-based target for treated feces and fecal sludge and aimed to ascertain the effectiveness and reduction rate of Ascaris spp. eggs in sludge at various lime doses, ammonia concentrations, and temperature values. Methods: Eggs were detected and enumerated using the flotation and sedimentation principle. The reduction process was performed in batches with quick lime doses of 30% and 50% w/w, ammonia concentrations of 1,000 and 5,000 mg/L, and temperatures of 30°C and 50°C. Results and Discussion: The number of eggs of Ascaris spp. fertile in the ponds was 1.38 ± 1.38 eggs/gram to 42.98 ± 13.09 eggs/gram, and the infertile amount was 0.46 ± 0.80 eggs/gram to 17.82 ± 6.55 eggs/gram. Using a temperature of 40°C, 50% CaO, and 5,000 ppm ammonia resulted in the highest percentage of reduction, 97.98 - 98.09% but 1.12 eggs/gram was remaining. Conclusion: Higher pH and ammonia levels primarily affect egg decrease in Ascaris spp. To reduce 99% of Ascaris spp. eggs until it reaches <1 egg/g, a dose of 50% CaO is required, with 5,000 ppm ammonia at a temperature of 40°C for 2.7 hours.

Permasalahan pengelolaan sampah salah satunya terkait dengan ketersediaan lahan yang terbatas masih belum dapat teratasi terlebih di wilayah-wilayah urban dengan pertumbuhan penduduk yang pesat. Selain itu, pertumbuhan penduduk juga berimbas kepada peningkatan konsumsi energi primer yang didominasi oleh bahan bakar fosil yang sifatnya tidak terbarukan dan menghasilkan emisi berbahaya bagi lingkungan sekitar. Refused Derived Fuel (RDF) merupakan salah satu alternatif solusi bagi kedua permasalahan tersebut. RDF adalah bahan bakar atau bahan baku yang dibuat sebagai hasil pengolahan sampah untuk menghasilkan bahan bakar yang memiliki kualitas yang konsisten. Timbulan sampah di Tempat Pemrosesan Akhir (TPA) Banyuroto Kulon Progo dianalisis untuk dapat diketahui potensinya sebagai bahan baku RDF. Penelitian dilakukan untuk menghitung timbulan sampah combustible, menghitung persentase kadar air sampah combustible, dan nilai kalor sampah combustible di TPA Banyuroto. Hasil dari penelitian menunjukkan bahwa timbulan sampah di TPA Banyuroto adalah sebesar 94.11%, kadar air timbulan sampah di TPA Banyuroto adalah 25.7% dan nilai kalor timbulan sampah di TPA Banyuroto adalah sebesar 5544.569 Kkal/kg, sehingga timbulan sampah di TPA Banyuroto terkategori sebagai potensial untuk bahan bakar RDF dengan potensi sebesar 29.84 ton/hari.

The presence of heavy metal Cr(VI) in water indicates environmental pollution. Heavy metal Cr(VI) that exceeds the standard can be harmful to health because it is toxic and carcinogenic. Activated carbon can be used as a heavy metal adsorbent. Modification of activated carbon using nitric acid can increase metal adsorption capacity. Therefore, this study aims to determine the kinetic of hexavalent chromium (Cr(VI)) removal by corn cob-based activated carbon modified with nitric acid. The modified activated carbon was characterized by Boehm titration and FTIR spectrophotometer. The adsorption capacity was identified in various parameters, involving the initial concentration of Cr(VI), pH value, contact time, and concentration of the adsorbent to obtain the optimal Cr(VI) removal efficiency value. The most optimal Cr(VI) adsorption was obtained at an activated carbon dosage of 3 g/L, pH value of 1, contact time of 140 minutes, and 100 mg/l Cr(VI) concentration. Based on adsorption kinetics data, the pseudo-second-order equation was obtained (R2 =0.994). The adsorption phenomenon followed the Langmuir isotherm model (R2 = 0.998) with an optimum adsorption capacity of 28.32 mg/g. Corn cob-activated carbon modified with nitric acid has many acidic groups that act as effective active sites for reducing Cr(VI) from water.

Microplastics are plastic particles with a size less than 5 mm which pose a growing concern in terms of ecotoxicology in aquatic environments and human health. Despite the widespread presence of microplastic pollution in land, water, and air, these environments are often viewed in isolation, although they are intricately interconnected. This study endeavors to examine the existing scientific literature pertaining to microplastic research across various environmental compartments and identify research gaps to shape future priorities. Scientific papers addressing microplastic pollution, published between 2014 and 2023, have been identified in the Web of Science database. Original research articles categorized under Environmental Sciences, Marine/Freshwater Biology, Toxicology, Multidisciplinary Sciences, Environmental Studies, Oceanography, Limnology, and Ecology in the Web of Science are chosen for a detailed investigation into microplastic research in seas, estuaries, rivers, lakes, soil, and the atmosphere. The selected papers for seas, estuaries, rivers, and lakes are further categorized based on (i) occurrence and characterization, (ii) uptake by and effects on organisms, and (iii) issues related to fate and transport. The findings indicate that, despite significant scientific research on marine microplastics, our understanding of the extent of microplastic pollution in continental environments, including rivers, lakes, soil, and air, as well as the associated environmental interactions, remains limited.

Plastic particles with various size variations such as microplastics are environmental contaminants that are widely found in waters and have the potential to cause negative impacts. The process of identifying plastic particles using microscopic imagery manually takes a lot of time and considerable cost. In order to provide an alternative solution as part of early detection, microscopic image-based plastic particle detection was carried out with the YOLOv8 architecture, accompanied by an estimate of microplastic abundance in microplastic units per cubic meter. This study aims to develop and evaluate the detection of plastic particles in microscopic images of river water. This research dataset consists of 300 microscopic images taken from three river locations in Indonesia and annotated for model training and testing. The results of the evaluation showed that the proposed model had an aggregate performance value with a precision value of 0.786, recall of 0.66, and mAP@0.5 of 0.731. Additional test results show that with the addition of image resolution, the precision value can increase to 0.804 and the value mAP@0.5 increases to 0.762, even at the expense of computing time, which is also increasing. Extended scenario-based analysis showed that more than 87% of the detected objects fell into the category of small objects, affecting the localization sensitivity and variability of the estimated MPS value. This study also validated the results of object detection with FTIR-based laboratory tests using a full quantitative agreement between the model detection results and the identification of plastic particle materials at the sampling location level. The main contribution and findings of this study is an integrated evaluation framework for object detection, particle size characterization which is expected to be an alternative to the initial screening tool for plastic particle content.

Waste from coal-burning power stations and other sectors that rely on coal as a source of energy is one of the environmental issues. Fly ash obtained from burning coal causes pollution in the surrounding environment. Subsequently, a great deal of study was conducted on the application of flying ash coal. Among the techniques for making use of the flying ash of coal is the extraction of silica. This study carried out silica leaching using Aqua Regia (a combination of HCl and HNO₃) with various ratios of 1:1, 1:3, and 3:1. The leaching process was carried out at varying temperatures of 30, 45, 60, 75, and 90 °C, with a leaching time of 1 and 2 hours. Precipitates containing silica were analyzed for their levels using XRF. The results of the study show that the ratio HCl:HNO₃ 3:1 is able to extract more silica than other solvent ratios.Keywords:Silica, Fly Ash, Leaching, HCl, HNO₃
