Abstract

Ajatappareng is a region in South Sulawesi Province, Indonesia which consists of four regencies and one administrative city. The regencies are Barru, Sidenreng Rappang, Pinrang, and Enrekang while the city is Parepare. The area has experienced a significant growth in terms of population which further leads to an increase in waste generation. Waste are a major challenge for environmental management especially due to the role in producing carbon emissions.  Aim: This study aims to assess the carbon emissions produced in waste management sector of the Ajatappareng Region. Methodology and results: The GHG Simulation-Version II spreadsheet was used to assess the GHG emissions from the transportation of waste in the respective regencies. Mathematical formulas were provided in the cells to calculate the GHG emissions of the simulation developed. Conclusion, significance, and impact study: The results showed that the volume of carbon emissions was 16,299.84 kg CO2-eq/month for Barru Regency, 17,076.03 kg CO2-eq/month for Sidrap Regency, 16,817.30 kg CO2-eq/month for Parepare City, 17,722.85 kg CO2-eq/month for Pinrang Regency, and 19,145.85 kg CO2-eq/month for Enrekang Regency. Moreover, the GHG emissions from mixed waste in the final disposal site were 918,531.01 kg CO2-eq/month, 1,733,537.85 kg CO2-eq/month, 1,404,917.59 kg CO2-eq/month, 1,723,004.12 kg CO2-eq/month, and 523,506.36 kg CO2-eq/month, respectively. Therefore, potential efforts are required to reduce CO2 emissions by optimizing waste transportation, promoting recycling, managing organic waste through composting, as well as improving collaborations with the private sector.

Abstract

This study investigates the combination of Fly Ash (FA), Bottom Ash (BA), and Soil (S) as a potential bottom liner in landfills. It is expected to cover the need for sustainable environmental technology, maintain structural strength, and prevent heavy metal pollution in rapidly urbanizing areas, while considering problems related to urban waste management. Aim: Evaluate FABA-Soil mixture as an alternative bottom liner material in landfill by assessing geotechnical performance and Cadmium (Cd) adsorption capacity. Methodology and results: The research explores two issues: mechanical stability (specific gravity, void ratio, compaction, and permeability) and mitigating Cadmium contamination from landfill leachate. Four mixture compositions (FBS1-FBS4), 15%, 30%, 50%, and 65% FABA content, were tested. Laboratory tests are conducted, including compaction, permeability, and adsorption continuous column tests. The results showed that intermediate FABA content (FBS2 and FBS3) may have stronger mechanical stability compared to others. For permeability, all values exceeded the regulatory standard. In the case of adsorption capacity, all compositions effectively removed Cd from the leachate. Conclusion, significance, and the impact study: Results on void ratio (e) and maximum dry density (MDD) suggested that a suitable mixture design may enhance long-term mechanical performance under a normal urban landfill loading situation. The FABA-soil mixture shows promise as an alternative landfill liner in moderate proportions and demonstrates excellent adsorption of heavy metals. All the attributes support general objectives of sustainable urban development and circular resource management, align with sustainable cities and communities, and responsible consumption and production.

Abstract

Aims: This study was aimed to Supit Urang Landfill in Malang, East Java, Indonesia, urgently needs a smart waste management system because it is strategically important as a large landfill with a monthly operating capacity of 4.560 trucks. Landfill management is very challenging due to some cases, such as overcapacity, inefficient waste sorting, and environmental risks. Methodology and results: The research introduced an integration of Internet of Things (IoT) and Artificial Intelligence (AI) into the waste management system to support the principles of a circular economy. IoT was applied for real time monitoring of waste conditions, while AI was utilized for big data analytics, enabling predictions, decision-making support, and policy recommendations. The results demonstrated that the proposed system improves efficiency and cost-effectiveness by reducing the amount of waste disposed of in the landfill and optimizing the waste sorting and recycling process. Conclusion, significance and impact study: The study concludes that the transformation toward a sustainable waste management model is urgently needed and can be achieved through AIoT integration. This innovation supports circular economy practices by enhancing waste reduction, reuse, and recycling. The successful implementation at Supit Urang could serve as a scalable model for other landfills across Indonesia, thereby contributing to national strategies for sustainable waste management. This technological intervention not only improves environmental outcomes by reducing pollution and conserving resources but also fosters economic development through efficient resource utilization and job creation in the recycling and waste processing sectors.

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.
