Abstract

Aim: This study aimed to evaluate the performance of 30% and 50% Reclaimed Asphalt Pavement (RAP) mixtures incorporating polymer as a recycling agent. Multi-layer Plastic (MLP) waste was used along with the coupling agent lignin to improve compatibility between the materials. Methodology and results: RAP was processed to separate the aged binder from the reclaimed aggregate, and both components were characterized by physical analysis. The results showed that the presence of aged asphalt in RAP affected the gradation consistency and decreased the bulk density of the RAP aggregate. The Asphalt Concrete-Wearing Course (AC-WC) specification was applied, and analyses were completed based on Marshall mix design parameters. The results indicated an increase in the stability values of the RAP mixtures by up to 15%. This condition was accompanied by increased volumetric parameters, causing the 50% RAP mixture to exceed the allowable threshold values. The recycling agent provided better compatibility, resulting in a decrease in the void percentage of the 30% RAP mixture. The Residual Strength Index (RSI) analysis demonstrated that the recycled mixtures exhibited better resistance to moisture, particularly the 30% RAP mixture, which showed more than a 10% increase in the RSI value. Conclusion, significance and impact study: The recycling agent is crucial in reducing the porosity and air voids in mixtures containing RAP. Increased adoption of mixtures incorporating solid construction waste, such as RAP, can contribute to the conservation of natural resources. Substituting new asphalt and aggregates with recycled materials will help achieve sustainability goals in road construction projects.

Aim: to select sustainable coastal city management policies that have the best chance of success. Methodology and results: First, identify problems based on 31 previous research results. The results are problems in Labuan Bajo city management. Second, discuss the problems in FGD stakeholders and experts. The results of the FGD are 61 variables in sustainable coastal cities management, consisting of 11 socio-cultural variables, 17 economic variables, 7 environmental variables, and 25 governance variables. Third, analyzing the reciprocal influence relationship between 61 sustainability variables using the MICMAC technological approach. The results are 21 key variables, 13 critical variables, 23 output variables, and 4 inert variables. Fourth, determine hypotheses/policies and their probabilities through FGD stakeholders and experts. The results are 6 hypotheses/policies and their probability values. Fifth, analyzing 64 alternative scenarios (policy combinations) using the SMIC-Prob technological approach. The results of the analysis are scenarios, their probabilities, and degrees of elasticity. Conclusion, significance and impact study: The highest probability is 12.2%, namely scenario of 111011 (combination of all policies except the 4th policy, namely the policy of "Local workforce capacity development and expansion of employment opportunities/P4).: A technological approach to multi-criteria analysis significantly facilitates urban and environmental planners in finding solutions to the complex problems involved in decision-making regarding sustainable coastal urban development policy scenarios. This approach ensures a transparent and participatory policy planning process, ensuring that the resulting policies meet the interests of all stakeholders.
ASSESSMENT OF CARBON EMISSIONS FROM THE WASTE MANAGEMENT SECTOR IN AJATAPPARENG REGION, SOUTH SULAWESI, INDONESIA Rahim, Irwan Ridwan; Sari, Kartika; Mukrim, Muhammad Ihsan Mukrim; Iman, Alfiyah Zhafirah; Taweesan, Achara; Swe, Zin Aung

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.
