Abstract

The dispersion of pollutants originating from traffic activities has become a major environmental issue in many developing countries. Emissions such as SO2 and CO present significant challenges for air quality management due to their serious health impacts. Air Quality Monitoring Systems (AQMS) are commonly used to measure pollutant concentrations; however, limited availability and spatial coverage necessitate alternative approaches such as dispersion modeling using AERMOD. This study aims to evaluate the performance of AERMOD as an alternative method for estimating SO2 and CO concentrations, particularly those associated with traffic-related emissions. The simulation results indicate a strong alignment between dominant wind direction and pollutant dispersion patterns over the seven-day modeling period. Concentration accuracy assessed through regression analysis and Root Mean Square Error (RMSE) revealed positive correlations between AERMOD simulations and observational data for both SO2 and CO, with RMSE values of 21.86 µg/m3 for SO2 and 485.25 µg/m3 for CO. Overall, statistical evaluations demonstrate a high level of agreement for SO2 and a moderate level of agreement for CO. These findings underscore the significant potential of AERMOD as an alternative monitoring tool for estimating pollutant dispersion in areas lacking AQMS infrastructure, thereby supporting more effective air quality management and pollution control strategies. However, the model’s performance remains influenced by several limitations, including dependency on the quality of meteorological and emission input data, the assumption of steady-state atmospheric conditions, and greater prediction uncertainty for CO compared to SO2. These factors should be carefully considered when applying AERMOD in regions without ground-based monitoring stations.

Abstract

Kontaminasi air oleh mikroorganisme patogen merupakan masalah kesehatan global yang membutuhkan solusi disinfeksi yang efektif dan mudah diakses. Penelitian ini bertujuan untuk fabrikasi agen antimikroba ramah lingkungan berbasis Lapisan Ganda Hidroksida (layered double hydroxide/LDH) pada substrat aluminium foil yang mudah diproduksi dan diaplikasikan untuk disinfeksi air. Morfologi seperti lembaran memungkinkan pengambilan kembali LDH yang pada dasarnya berbentuk bubuk, dari air yang telah disterilkan sebelumnya secara batch. Pelapisan foil aluminium dengan Mg-Al LDH dicapai dengan merendamnya dalam larutan magnesium alkali, yang menghasilkan pembentukan LDH di permukaan. Material yang dihasilkan dikarakterisasi menggunakan Difraksi Sinar-X (XRD) dan Mikroskopi Elektron Pemindaian (SEM) untuk menganalisis struktur kristal dan morfologi permukaan Uji aktivitas antimikroba menunjukkan bahwa material LDH pada aluminium foil memiliki kemampuan menghilangkan Eschericia coli dengan efisiensi penyisihan mencapai 90,9% dalam waktu 3 jam. Studi ini menunjukkan bahwa LDH pada aluminium foil berpotensi diaplikasikan sebagai agen antimikroba ramah lingkungan dan praktis untuk disinfeksi air, seperti air ceret dalam skala rumah tangga.

Abstract

Artisanal and small-scale gold mining (ASGM) provides short-term income for rural communities but frequently creates environmental, safety, and governance problems when it operates outside formal control. This study aimed to analyze the existing condition of ASGM, identify the driving and inhibiting factors of its arrangement, describe the perceived impacts, and formulate strategic directions for ASGM arrangement in Karang Jaya District, North Musi Rawas Regency, Indonesia. A qualitative descriptive approach was applied using semi-structured interviews supported by secondary data on the study area, population, and agricultural land use. Twenty-two informants represented district officials, village officials, technical agencies, company representatives, community leaders, nearby residents, and ASGM actors. Data were analyzed through reduction, presentation, interpretation, and conclusion drawing. The findings show that ASGM development is driven by gold potential, mining history, household economic pressure, limited alternative employment, and weak field control. The main impacts include land degradation, open mining pits, landslide and occupational accident risks, and mercury-related water and soil contamination. The recommended strategy combines alternative livelihood development, skills training, local economic institutional strengthening, gradual area monitoring, land rehabilitation, and mercury-risk education.

Abstract

The governance of sand and gravel mining requires an integrated assessment of technical planning, occupational safety, environmental control, reclamation, and regulatory compliance. This study evaluated the governance of CV. Ria Bersaudara, a sand and gravel mining company located in Pasar Surulangun, Rawas Ulu District, Musi Rawas Utara Regency, using the Good Mining Practice framework. The study used a descriptive evaluative approach based on field observation, document review, indicative resource estimation, equipment productivity analysis, occupational safety and environmental risk assessment, and compliance mapping. The results show that the company has a basic legal foundation through an exploration mining permit covering 12.5 ha; however, several governance components require improvement. The indicative prospective area was approximately 2.50 ha, with an effective follow-up area of 1.80 ha and an estimated indicative resource of 21,600 m³ or 35,640 tons. Productivity analysis indicated that excavator capacity reached about 61 m³/hour, while one dump truck only transported about 10.3 m³/hour, creating a haulage bottleneck if the truck fleet is insufficient. Safety implementation was also not optimal, with personal protective equipment compliance estimated at only 55%. The study recommends validating permit documents, strengthening technical exploration data, improving drainage and sediment control, enforcing safety procedures, implementing progressive reclamation, and establishing daily operational records.

Abstract

Solid waste management in Musi Rawas Regency faces increasingly complex operational, spatial, and environmental challenges. The main problems are not limited to the amount of waste transported to the landfill, but also include limited service coverage, insufficient fleet capacity, incomplete intermediate treatment facilities, weak source separation, and the high dependence on Gegas landfill/final processing facility as the dominant downstream infrastructure. This study aimed to describe the existing solid waste management system, identify the major technical and governance constraints, and formulate an environmental-based strategy that is consistent with the territorial characteristics, service capacity, and local waste generation pattern of Musi Rawas Regency. A descriptive qualitative case-study approach was applied through semi-structured interviews, field observation, and document review. The results show that collected waste under normal conditions ranged from 19 to 21 tons per day and increased to approximately 25 tons per day during Ramadan due to seasonal consumption and organic waste from temporary trading activities. Waste services were supported by seven dump trucks for seven service areas, indicating that a substantial part of the regency had not been covered by formal collection services. Meanwhile, the potential waste generation based on population data reached 288.25 tons per day, showing a wide gap between transported waste and estimated total generation. The proposed strategy emphasizes waste data strengthening, service zoning, route and trip optimization, TPS/TPS3R revitalization, organic waste treatment, landfill risk control, operational standard procedures, and performance-based financing. These interventions are expected to improve service efficiency, reduce landfill burden, minimize environmental risk, and support more adaptive and sustainable local waste governance.

Abstract

This study aimed to evaluate the efficiency of microplastic removal using filtration media composed of coconut shell biochar and polyurethane sponge, as well as to assess the potential toxicity of the filtered water on feed consumption efficiency in Oreochromis niloticus and microplastic bioaccumulation by fish. The filtration system had a diameter of 10 cm, employed an upward flow configuration, and operated at a flow rate of 30 mL/min. Optimization was conducted using an artificial solution containing microplastics through two series-connected filtration columns with a media thickness of 40 cm. Toxicity tests on the filtered water were performed on Nile tilapia using feed efficiency and the fish’s bioaccumulation capacity of microplastics as parameters, with fish sized 4-5 cm. Results showed that the highest microplastic removal efficiency for the first and second filter averaged 79% and 93%, respectively. Toxicity tests based on feed efficiency showed favorable percentages in experiments using the effluent from the second series column filter compared to the first series, even though the fish feed efficiency of both water effluent decreased on day 14. The highest microplastic accumulation was observed in the digestive tract, followed by the fish gill and fish muscle, respectively. The bioaccumulation factor (BAF) value of microplastic in fish was less than 1, indicating a low level of bioaccumulation. This study demonstrates that the combination of coconut shell biochar and polyurethane sponge in two series of filtration has strong potential as an effective, economical, and accessible solution for microplastic filtration in water treatment.

Abstract

This study examines the resilience variables of urban Drinking Water Supply Systems (WSS) in responding to floods, with a focus on West Sumatra Province, Indonesia, using the Fuzzy Delphi Method (FDM). The study identifies three main resilience properties: robustness, recovery, and learning, within a temporal framework. Thirteen sub-properties and 41 indicators were validated using FDM by 10 experts in fields relevant to the research topic. As a result, 12 sub-properties were accepted by expert consensus, while one sub-property, namely governmental situation awareness, was rejected because all three of its indicators failed to meet the validation criteria. A total of 33 out of 41 indicators were considered significant, relevant, and useful by the expert panel. Furthermore, the findings emphasize the critical role of the governmental dimension in determining the resilience level of SPAM in West Sumatra Province. These results will serve as a guide for policymakers in prioritizing resilience-based decisions to mitigate flood threats.

Abstract

Air pollution is one of the most pressing environmental issues, with direct impacts on human health and environmental quality. The increasing intensity of transportation activities, industrial operations, forest and land fires, and regional development in South Sumatra Province has increased the risk of air pollution, particularly from nitrogen dioxide (NO2) and sulfur dioxide (SO2). This study aims to analyze the concentrations and multi-year trends of NO2 and SO2 in South Sumatra based on passive sampler measurements conducted at 68 monitoring sites across 17 districts and municipalities during the period 2021–2024. The results show that the average concentrations of NO2 ranged from 6.654 to 9.944 micrograms per cubic meter, while SO2 concentrations ranged from 7.303 to 8.456 micrograms per cubic meter. All measured concentrations were below the National Ambient Air Quality Standards as well as the European Union guideline values. Trend analysis indicates a consistent decrease in NO2 and SO2 concentrations from 2021 to 2024. These findings contribute to the availability of long-term air quality data and enhance understanding of NO2 and SO2 dynamics, providing a scientific basis for the development of evidence-based strategies for air pollution control and prevention in South Sumatra Province. Keywords: nitrogen dioxide, sulfur dioxide, passive sampler, South Sumatra, air pollution trends.

Abstract

The objective of this study is to evaluate the horizontal distribution of particulate matter concentrations (PM10 and PM2.5) in ambient air within the vicinity of the cement factory, with consideration for variations in spatial and temporal. The measurements were conducted using the EPAM 5000 instrument, with a total of six sampling points at distances of 0 km, 0.5 km, 1 km, 1.5 km, 2 km and 2.5 km, both during the day and at night, over a period of three days. Meteorological parameters such as air temperature, relative humidity, air pressure, and wind speed were measured to analyses their influence on particulate matter distribution. The findings revealed that the highest PM10 and PM2,5 concentrations were measured at the location closest to the factory (B1) with values of 113.98 μg/m³ and 75.73 μg/m³ at night and 52.80 μg/m³ and 28.27 μg/m³ during the day. A clear pattern of decreasing concentrations of both types of particulates as the distance from the source increases is evident, with a significant decrease occurring at a distance of 0-0.5 km. The PM2.5/PM10 ratio at night (0.67) was higher than during the day (0.56), indicating a greater contribution of fine particulates at night. Meteorological conditions play an important role in the distribution of particulate matter, in particular changes in wind direction and wind speed at night contribute to differences in the concentration and distribution of particulate matter. The results of this study indicate an increased risk of exposure to particulate matter in areas near factories, especially at night, which can be a basis for consideration in the preparation of air pollution control policies and efforts to safeguard public health.

Abstract

Solid waste management in Padang City is problematic due to the annual increase in waste generation, which leads to various environmental issues. This study aims to predict the most profitable waste-to-energy (WtE) treatment methods from technical and environmental perspectives that can alleviate these issues in Padang City. The study begins with analyzing solid waste generation, composition, and characteristics. Additionally, the amount of incoming waste for thermal planning is projected based on projected generation and population. The environmental implications were assessed using the LCA (Life Cycle Assessment) method. Various waste treatment methods' technical and environmental viability was evaluated, focusing on projected waste generation in 2031, estimated at 929 tons/day. The analysis of technical aspects revealed that thermal processing of mixed waste gasification is the most profitable option, requiring only 5,101 m2 of land and capable of producing 188 GWh/year while achieving the lowest LCA Single Score of 5.82E+04 Conversely, anaerobic digesters and RDF processing generate 120 GWh and 47 GWh of electrical energy, respectively, with Single Score LCA of 4.25E+10 Pt and 7.74E+09 Pt. However, the environmental impact of WtE is the most significant, primarily due to its contribution to global warming. Global warming is predominantly attributed to carbon monoxide (CO) compounds, with carbon dioxide (CO₂) being the primary emission responsible for the observed increase in global temperature.
