Abstract

Aim: The study aims to design and develop a bedside table using recycled wood and plywood waste while incorporating an indoor air quality (IAQ) monitoring system to improve indoor environmental health within the context of interior design innovation. Methodology and results: The study employs a qualitative design thinking approach, following the five key stages: empathize, define, ideate, prototype, and test. The bedside table is developed using upcycled wood waste and features an integrated IAQ monitoring system based on Arduino Nano's technology. The system includes DHT11 sensors for temperature and humidity monitoring and additional sensors for detecting CO and CO₂ levels. The results demonstrate that utilizing wood waste in furniture production effectively reduces landfill dependency while contributing to sustainable material use. Moreover, the embedded IAQ monitoring system enhances user awareness of indoor environmental conditions, supporting healthier living spaces. This research demonstrates the feasibility of integrating sustainable design and technological innovation to address environmental and health challenges in furniture interior design. The study enhances resource efficiency by repurposing wood waste into functional furniture while improving indoor air quality through smart monitoring technology. Conclusions, Significance, and Impact Study: The findings highlight the potential of smart furniture in promoting sustainability and health-conscious living. This study provides a practical framework for future furniture designs that support ecological responsibility and user well-being. This research sets a foundation for innovative product development in the furniture industry by bridging sustainable materials with IoT-based monitoring.

Abstract

Aim: This study aims to evaluate the influence of gold tailings waste (GTW), nickel slag (NS), and rejected plastic (RP) as partial substitutes for cement and fine aggregates on the mechanical and physical properties of lightweight concrete blocks for sustainable construction applications. Methodology and Results: GTW was substituted at 5% by weight of cement, while NS and RP replaced fine aggregates at variations of 10–20% and 10–15%, respectively. Concrete specimens were cast, cured, and tested in accordance with SNI and ASTM standards. Compressive strength and density were measured at 7, 14, and 28 days, while splitting tensile strength and porosity were evaluated at 28 days. The results show that compressive strength increased with curing age, reaching 1.56–2.37 MPa at 28 days. The optimal mixture (BR 5GTW 20NS 10RP) achieved 1.93 MPa, exceeding the minimum SNI requirement of 1.8 MPa for lightweight concrete blocks. Density values ranged from 683 to 1001 kg/m³, confirming the lightweight classification. Splitting tensile strength ranged between 0.315 and 0.388 MPa, while porosity varied from 4.38% to 8.12%, indicating acceptable physical performance. Conclusion, Significance, and Impact of the Study: The incorporation of GTW, NS, and RP enhances mechanical performance while maintaining appropriate density and porosity. This approach offers a sustainable and cost-effective construction material by valorizing industrial waste, reducing environmental burdens, and supporting environmentally responsible urban infrastructure development.

Abstract

Aim: This study aims to develop an adaptive management and maintenance model for flexible pavement in coastal areas by integrating road condition evaluation, cost analysis, and the effects of seawater immersion. The model is intended to improve maintenance efficiency, extend pavement service life, and support sustainable infrastructure management. Methodology and results: A quantitative and experimental approach was employed. Field surveys assessed pavement conditions using the Pavement Condition Index (PCI), Surface Distress Index (SDI), and International Roughness Index (IRI). Asphalt samples were tested in the laboratory under seawater immersion to evaluate strength reduction through Marshall and Indirect Tensile Strength tests. Damage data were integrated with maintenance cost analysis and traffic volume, producing a predictive model using regression and correlation analysis. Initial results indicate that seawater immersion significantly accelerates pavement deterioration and increases maintenance costs compared to normal conditions. Conclusion, significance, and impact study: he proposed model provides a comprehensive framework by considering technical, economic, and environmental factors specific to coastal infrastructure. Findings highlight the importance of condition-based maintenance strategies that are adaptive to climate change and extreme environmental risks. This study contributes to achieving sustainable infrastructure, resilient cities, and climate action for coastal environments.

Abstract

Aim: The goal of this study is to evaluate the sustainability performance of the Maggot-in-the-Box system, a household-scale organic waste management solution in Indonesia, from environmental, economic, and social perspectives. Methodology and results: The study used an integrated assessment framework, which is a combination of Life Cycle Assessment (LCA), Cost–Benefit Analysis (CBA), and social perception analysis. Furthermore, environmental performance was assessed using LCA and the focus is on Global Warming Potential (GWP) (per kilogram of biowaste). CBA was used to evaluated Economic feasibility considering net profit, payback period, and Net Present Value (NPV). Latent Dirichlet Allocation (LDA) topic modelling of user reviews was used to examine social acceptance. The results show the Maggot-in-the-Box system has very low emissions, with a GWP of 0.002576 kg CO₂-eq per kilogram of biowaste. In comparison with the Takakura composting method, this is about 27 times lower. It is just 3.6% of the combined emissions of all systems evaluated. Economically, the system has financial benefits, generating a net annual profit of IDR 2.38 million per household. The payback period is 3 to 4 months with a 5-year NPV of IDR 10.2 million at a 3% discount rate. Social analysis shows positive user perceptions regarding waste reduction and simplicity in the operation. Conclusion, significance and impact study: Research findings reflect how the Maggot-in-the-Box system achieves a strong balance between environmental performance, economic feasibility, and also social reception. Therefore, there is high potential that the system could be used as a practical and scalable household organic waste management solution in Indonesia.

Abstract

Aim: This study focuses on the main urban corridors of Makassar City and the short-term exposure levels of CO, PM2.5, and TSP resulting from traffic congestion during peak hours. Methodology and Results: Field measurements were conducted along three major corridors: Sultan Alauddin, A.P. Pettarani, and Urip Sumoharjo. The measurements included pollutant concentrations, traffic counts, and weather conditions during both peak and non-peak periods. The study employed a time-series quantitative observational design. The statistical analyses used were Pearson’s correlation, multiple linear regression, and the independent-samples t-test. The results revealed correlations of 0.98–0.99 between traffic volume and CO concentrations, and 0.94 for TSP. During peak periods, a strong correlation was observed between vehicle volume and PM2.5 levels, which exceeded WHO limits. TSP concentrations were also noticeably above the acceptable exposure range. CO concentrations were influenced by traffic volume and remained low but significant. Conclusion, Significance, and Impact of the Study: During peak traffic congestion, substantial tailpipe and non-tailpipe emissions are released, leading to the accumulation of pollutants along urban corridors. The implementation of a fully functional multi-corridor and multi-pollutant traffic and air quality monitoring system demonstrates an assessment framework that can be applied in other locations. These findings provide evidence to support sustainable urban transport systems and air quality management strategies, with expected outcomes including time-targeted traffic control and reductions in non-tailpipe emissions. Ultimately, these efforts contribute to achieving the Sustainable Development Goals (SDG 11 and SDG 3) related to improved air quality.
