Abstract

Aim: This study aims to investigate the efficiency of the Anaerobic Baffled Reactor (ABR) system in domestic wastewater treatment at the Graha Rectorate of the State University of Malang (UM), part of the UM Green Campus program. Methodology and results: The study was conducted by installing a laboratory-scale ABR system and investigating its performance in reducing pollutant concentrations. Sampling was carried out at the inlet and outlet ports, and the system was run for Hydraulic Retention Time (HRT) of 24 hours.  The samples were analyzed for chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS), Total Coliform (TC), pH, dissolved oxygen (DO), and temperature. The results showed that the ABR system with a flowrate of 1.408 m³/day and a reactor volume of 1.901 m³, consisting of 9 compartments, was able to reduce TSS and COD concentrations to meet the quality standards of Permen LHK No. 68/2016. Statistical tests showed significant reductions in COD, BOD, and TSS parameters. The removal efficiency of each parameter is TSS (91.33%), COD (40.44%), BOD (32.14%), and TC (51.18%). Conclusion, significance, and impact study: This study demonstrated that ABR is effective in treating campus wastewater, but further design optimisation or hybridisation with another system is still required. A combination of additional treatments is recommended to ensure compliance with regulatory standards and support the achievement of Sustainable Development Goals (SDG 6 and SDG 11), particularly in the areas of clean water and sanitation, as well as sustainable cities.

Abstract

Waste management poses a critical global challenge, particularly in developing countries. Refuse-Derived Fuel (RDF) offers a promising solution, necessitating holistic sustainability evaluations through Life Cycle Sustainability Assessment (LCSA). Aim: This study aimed to conduct a systematic and bibliometric review mapping trends, analyzing methodologies, identifying barriers, and evaluating strategies concerning LCSA development in RDF life cycles within developing countries. Methodology and results: Employing a Bibliometric-Systematic Literature Review (B-SLR) using Scopus data (2011-2024) and analyzed via VOSviewer and qualitative content analysis, the study identified 22 relevant publications. Findings reveal a fluctuating yet growing publication trend with increasing citations, though international collaboration remains limited despite concentrated productivity. Methodologically, studies predominantly use LCA and LCC, with scarce S-LCA integration; key themes include environmental impacts, waste-to-energy (especially RDF in cement), and circular economy. Implementation faces significant technical, economic, social, and regulatory barriers. Proposed strategies emphasize crucial advancements in infrastructure, process optimization, stakeholder engagement, and robust regulatory frameworks. Conclusion, significance and impact study: The findings confirm that while scholarly interest in LCSA for RDF is increasing, its application is fragmented and hindered by persistent barriers. This research provides a crucial synthesis of evidence-based insights for policymakers and enriches academic understanding of LCSA in alternative waste management. Future work should prioritize developing integrated LCSA methodologies (especially for S-LCA), addressing critical data gaps, conducting holistic case studies, fostering international collaboration, and validating proposed strategies to accelerate sustainable RDF adoption and comprehensive waste management.

Abstract

Aim: This study evaluated air quality, worker exposure, and health risks at a 3R Integrated Waste Processing Facility in Banyumas Regency, Indonesia, where waste is combusted for extended periods. Methodology and results: Over five consecutive days, concentrations of PM2.5, PM10, CO2, CO, and respirable dust were measured during morning and afternoon shifts. Results revealed persistently hazardous particulate matter levels: PM2.5 exceeded World Health Organization (WHO) limits by 10–90 times, and PM10 by 5–44 times, with no significant difference between sampling periods (p > 0.05). Respirable dust and CO remained within safe thresholds, while CO2 was consistently elevated during morning startup operations. Risk Quotient (RQ) analysis identified CO2 as the only pollutant above the safety threshold (RQ = 1.184), correlating with worker-reported symptoms such as dizziness, fatigue, and difficulty concentrating. Intake calculations confirmed high chronic health risks, particularly for respiratory and cardiovascular disease. Conclusion, Significance, and Impact: Immediate interventions are required, including improved combustion efficiency, local exhaust ventilation, strict use of personal protective equipment, and regular worker health monitoring. Long-term strategies should focus on regulatory reform, advanced emission control technologies, and transitioning toward sustainable waste management through recycling, composting, and circular economy practices. These actions align with United Nations Sustainable Development Goals for health, sustainable cities, and climate action.

Abstract

Aims: This study aimed to develop an approach for disaster risk reduction in urban communities of the indigenous community in Kampung Kuta, West Java, to enhance disaster literacy. The primary issue addressed was the insufficient integration of traditional knowledge into formal disaster education, limiting the effectiveness of disaster preparedness in local communities. Methodology and Results: The study highlighted the inadequate integration of traditional knowledge into formal disaster mitigation, hampering the effectiveness of disaster preparedness in indigenous communities. A qualitative approach was employed, involving interviews, observations, and focus group discussions (FGDs) with local indigenous leaders and community members. The results reveal that Kampung Kuta's indigenous knowledge offers valuable practices for disaster mitigation, such as environmental management and communal responsibility, which could be integrated into formal mitigation frameworks. Transforming these traditions into resilience learning strategies could significantly enhance disaster literacy, fostering greater awareness and resilience within the community. The novelty of this research lies in the fusion of traditional and modern educational strategies, creating culturally relevant disaster education approaches that preserve indigenous knowledge and enhance its application in contemporary disaster management. Conclusion, Significance, and Impact: This strategy provides a viable model for other regions with strong traditions of local wisdom, contributing to the global discourse on integrating indigenous practices into disaster risk reduction (DRR) frameworks, especially in areas prone to natural disasters.

Abstract

Smoking represents a commonly observed behavior across various segments of society. Despite widespread awareness of its harmful effects, the number of smokers continues to increase each year. In the ASEAN region, Indonesia has the highest smoking prevalence. In Banjar Regency, 15–19-year-olds make up the majority (51.35%) of new smokers. One of the main reasons teenagers start smoking is the process of social adjustment within their environment. Aim: This study aims to design an application to prevent smoking behavior among teenagers and to implement the E-Nosmo application at SMPN 1 Aranio, ensuring it aligns with its intended objectives. Methodology and results: The E-Nosmo application was developed using a specific design methodology, beginning with the conceptual design phase, including system architecture and prototype development. After approval, the application was developed and tested to ensure it achieved its goals. The results showed that 57% of students were at risk of engaging in smoking behavior, while 43% were not. The most significant contributing factor was social influence, particularly from family members and peers who smoke. Other contributing factors included family background, parental support, and economic conditions. Interestingly, cigarette advertising did not play a role in influencing students’ smoking behavior. To maintain student engagement, the application also includes interactive games. Conclusion, Significance, and Impact Study: One important recommendation for improving the application is to simplify the wording of the questions used to detect smoking behavior, as some students found them too complex to understand.

Abstract

Rapid urbanization heightens the risk of land subsidence in Makassar City. Aim: This study analyzes and maps land surface deformation alongside Land Use and Land Cover (LULC) dynamics from 2020–2024. Methodology and Results by integrating multitemporal Sentinel-1 SAR (VV polarization) and supervised LULC classification from Landsat-8 on the Google Earth Engine platform. Annual LULC maps were produced using an SVM, yielding high accuracy (Kappa 0.893–0.988). Built-up land expanded mainly at the expense of vegetation and bare land. Deformation was inferred from temporal differences in VV backscatter (VV_diff); statistics were computed for each class. Negative VV_diff values were frequently observed in built-up and bareland areas, indicating subsidence. Significant interannual variability was observed in 2023-2024, particularly within the vegetation zones. Linear regression confirmed a strong negative deformation trend in built-up areas (slope −0.0123 dB/year). These results demonstrate a linkage between urban expansion and ground deformation. Conclusion, significance, and impact study: The approach provides a repeatable and cost-effective framework for continuous subsidence monitoring using open satellite data. GEE facilitates the open replication of workflows. The findings contribute to the field of urban planning and policy by identifying vulnerable zones, promoting risk-aware land allocation, infrastructure maintenance, and sustainable development methods for Indonesian coastal megacities and other rapidly expanding metropolitan areas.

Abstract

Aim: This study aims to assess the effectiveness of phytoremediation using Ipomoea aquatica and Lemna minor in reducing contaminants in catfish aquaculture wastewater, with particular attention to the effects of plant species and residence time in the wastewater. Methodology and Results: The phytoremediation tanks were constructed from Glass with dimensions of 40 cm (L) × 25 cm (W) × 30 cm (H). The effluent tank was made of a plastic basin with an approximate capacity of 3 liters. The treatment was conducted using a batch system. The independent variables in this study were plant type and retention time. The dependent variables comprised Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), phosphate and ammonia concentrations in the wastewater. The effectiveness of contaminant reduction varied depending on plant type and retention time, with significant reductions observed. The combination of Ipomoea aquatica and Lemna minor, with a retention time of 10 days (T3D3), achieved the highest removal efficiencies for BOD (96.15%), COD (83.63%), and 95.9% for Ammonia and Phosphate (91.87%). Conclusion, significance, and impact study: The phytoremediation process using different plant types and retention times effectively reduced BOD, COD, TSS, Ammonia, and phosphate levels in catfish aquaculture wastewater. Notwithstanding these advancements, the application of a combination of Ipomoea aquatica and Lemna minor for phytoremediation to mitigate pollutants in catfish aquaculture wastewater remains relatively unexplored.

Abstract

Aim: This study analyzes how land cover affects land surface temperature (LST). Understanding this helps optimize land management, improve agriculture, and address climate change impacts on soil temperature. Methodology and Results: To achieve this objective, the study employs a field experiment and remote sensing analysis to evaluate soil temperature variations. Land surface temperature data from Landsat satellite imagery enabled observation of the spatial distribution of soil temperature. The results indicate that sandy soils experience greater temperature fluctuations compared to clay soils, which are better at retaining heat over time. Conclusion, Significance, and Impact Study: This study confirms that soil texture and moisture content significantly influence land surface temperature dynamics. The findings can be applied to water management planning in the agricultural sector, climate change adaptation strategies, and more effective land use planning. The integration of remote sensing and field data improves the accuracy of large-scale soil temperature monitoring. Building on these results, future studies should specifically focus on quantifying the separate and combined effects of vegetation cover and organic matter content on soil thermal properties to further refine predictive models.

Abstract

Industrial wastewater treatment is increasingly recognized as a strategic sector for climate change mitigation. Integrating carbon credit mechanisms with process engineering solutions offers opportunities to convert pollution control infrastructure into measurable greenhouse gas (GHG) reduction assets by linking greenhouse gas recovery, energy utilization, and environmental compliance. Aim: This study aims to identify emission reduction potential and evaluate how financial incentives from carbon credit markets can enhance the feasibility of wastewater treatment investments for industries, municipalities, and Non-Governmental Organizations (NGOs). Methodology and results: using Clean Development Mechanism (CDM) and mixed-method approach, this study indicates promising results that anaerobic technologies such as Upflow Anaerobic Sludge Blanket reactors and covered lagoons can remove 70–90% of Chemical Oxygen Demand (COD) while producing recoverable greenhouse gas equivalent to significant Carbon dioxide emissions reductions annually. Compared with conventional aerobic treatment, inclusion of carbon revenue improves project attractiveness, with estimated payback periods between 3 and 7 years. Conclusion, significance and impact study: carbon credit opportunities in wastewater treatment are primary driven by techno-economic ability of process technologies to recover greenhouse gas, reduce emissions, and create economic value. the assessment shows that anaerobic systems provide both environmental improvement and financial returns, making industries more willing to adopt cleaner treatment solutions. The availability of carbon revenue increases the attractiveness of investment and accelerates modernization of existing facilities. Wastewater treatment industry is no longer viewed solely as pollution control units, but as platforms for energy recovery and climate mitigation. The implementation of carbon-oriented wastewater management supports urban environmental protection while strengthening industrial competitiveness. The approach contributes directly on achieving SDG 6.
