Abstract

The adoption of circular economy (CE) practices is essential for fostering sustainability in the construction sector, particularly in developing economies like Nigeria. This study investigates the barriers, opportunities, and strategies for advancing CE adoption in Nigeria’s construction industry. Using a mixed-methods approach, data were collected through surveys of 285 construction firms, semi-structured interviews with 40 stakeholders, and system dynamics modeling to evaluate policy scenarios. The findings reveal a low adoption rate of CE principles (18%), with large firms (42%) significantly outpacing SMEs (9%). Urban areas showed higher adoption rates (26%) compared to rural regions (12%), attributed to better access to infrastructure, market-driven incentives, and regulatory enforcement. Key barriers include high financial costs, regulatory gaps, and limited access to advanced technologies such as Building Information Modeling (BIM). Opportunities for accelerating CE adoption were identified, including public-private partnerships (PPPs) to bridge financial and technical gaps, increasing demand for sustainable practices from multinational clients, and integrating CE principles into educational curricula to address skill shortages. System dynamics modeling demonstrated that high policy interventions—combining financial incentives, regulatory reforms, and capacity-building initiatives—could achieve a 60% reduction in construction waste and a 40% improvement in resource efficiency by 2035. This study underscores the need for comprehensive policies, collaborative initiatives, and educational reforms to enable Nigeria’s transition to a sustainable construction sector. By aligning national strategies with global sustainability goals, particularly the United Nations Sustainable Development Goals (SDGs), Nigeria can position itself as a regional leader in sustainable construction.

Abstract

Kualitas air minum yang aman dan higienis di lingkungan universitas merupakan aspek fundamental dalam menjaga kesehatan sivitas akademika serta mendukung reputasi institusi sebagai ruang belajar yang berkelanjutan. Salah satu risiko utama terhadap keamanan air minum dan minuman olahan di kantin kampus adalah kontaminasi Escherichia coli (E. coli), yang menjadi indikator adanya pencemaran fekal. Studi ini tidak berfokus pada uji laboratorium, melainkan pada analisis dampak kualitatif dan evaluasi kebijakan pengendalian melalui pendekatan cost–benefit. Tujuan utama penelitian ini adalah untuk mengidentifikasi konsekuensi sosial, ekonomi, dan lingkungan dari potensi kontaminasi E. coli, menilai efektivitas pendekatan pencegahan berbasis investasi higienitas, serta merumuskan strategi kebijakan jangka pendek, menengah, dan panjang di tingkat universitas. Analisis dilakukan menggunakan kerangka SWOT dan matriks aksi strategis (Strategic Action Matrix) untuk merumuskan langkah implementasi yang realistis, terukur, dan berorientasi pada keberlanjutan. Hasil analisis menunjukkan bahwa penerapan sistem desinfeksi air, pelatihan kebersihan bagi pengelola kantin, dan pembentukan mekanisme pemantauan kualitas air secara berkala memberikan manfaat sosial dan ekonomi yang signifikan dibandingkan pendekatan reaktif. Upaya preventif ini terbukti memperkuat tata kelola air kampus, meningkatkan kepercayaan mahasiswa terhadap keamanan konsumsi, dan mendukung penerapan prinsip green campus.

Abstract

Circular economy (CE) implementation offers promising pathways for sustainable development, resource efficiency, and waste minimization. However, the transition from linear to circular systems presents considerable engineering management challenges, especially in developing economies such as Nigeria, where socio-institutional complexity, regulatory uncertainty, and infrastructural limitations persist. This study critically examines the risk landscape associated with engineering-managed CE projects in Nigeria, with the objective of identifying, quantifying, and prioritizing key risk factors that undermine project delivery and long-term sustainability. A sequential exploratory mixed-methods design was adopted, combining qualitative insights from expert interviews with advanced quantitative modeling. Risk data were analyzed using Monte Carlo simulation to estimate probabilistic impact, Principal Component Analysis (PCA) to uncover latent risk structures, and Fuzzy Analytic Hierarchy Process (FAHP) to prioritize mitigation strategies under uncertainty. Five major risk dimensions were evaluated: technical failure, regulatory delay, stakeholder conflict, financial overrun, and supply chain disruption. Findings revealed that stakeholder conflict and regulatory delay are the most severe and probable risks, accounting for the highest variance in risk exposure. Technical risks, while relevant, were found to be less critical in shaping project success than governance-related variables. The analysis underscores the need for a shift in engineering risk management from traditional design-centric models to integrative frameworks that incorporate policy, finance, and stakeholder dynamics. This research offers a replicable methodological approach for CE project risk analysis in developing countries. It also provides evidence-based guidance for engineering managers, policymakers, and investors seeking to enhance the resilience and performance of CE infrastructure.

Abstract

The aim of this study is to address the critical sustainability challenges in prefabricated construction (PC) by developing an AI-driven Building Information Modeling (BIM) system that enables collaborative prediction and optimization of carbon emissions and energy efficiency. By integrating deep learning techniques with BIM technology and PC manufacturing processes, this research examines the synergistic optimization of environmental performance across the entire lifecycle of prefabricated buildings. A comprehensive simulation test was performed on a selected residential PC project, focusing on carbon footprint reduction and energy consumption optimization. The findings revealed that the AI-driven system achieved carbon emission reductions of 17.8% and energy efficiency improvements of 22.3% compared to conventional approaches. The combination of BIM technology and deep learning models substantially enhanced sustainability performance through intelligent optimization of PC component design, manufacturing processes, and assembly sequences. Data analysis showed that the convolutional neural network (CNN) algorithm achieved prediction accuracy above 92% for both carbon emissions and energy efficiency metrics, with mean absolute percentage error (MAPE) approximately 8%. This integrated framework provides a transformative approach to achieving carbon neutrality goals in the construction industry.

Abstract

This study examines the determinants of community digital participation in marine waste management in Batam, Indonesia, focusing on the roles of adaptive capacity, attitudes, subjective norms, perceived behavioral control, and intention. A structured survey of 450 respondents was conducted, and the data was analyzed using Structural Equation Modeling (SEM). The descriptive analysis shows that respondents strongly recognize the importance of social media in protecting Batam’s coastal environment and receiving encouragement from family and peers, yet actual behavioral participation remains relatively low. Measurement results confirm that all construction demonstrates high reliability and validity, with the model explaining 62.2% of the variance in willingness to participate. Structural relationship testing reveals that adaptive capacity exerts the strongest direct effect on both intention (β = 0.79, p < 0.001) and willingness to participate (β = 0.613, p < 0.001), while intentions significantly predict willingness to participate (β = 0.775, p < 0.001). In contrast, attitudes, subjective norms, and perceived behavioral control have indirect or nonsignificant direct effects. These findings suggest that digital participation in environmental initiatives depends less on awareness alone and more on adaptive skills and motivational commitment. The study highlights the importance of digital literacy, capacity building, and intention-driven interventions for strengthening marine waste management in emerging coastal cities.

Abstract

The growing demand for environmentally responsible products presents new opportunities for the Indonesian batik industry to strengthen its competitiveness while supporting sustainable development objectives. Eco-labeling has emerged as a potential instrument for communicating environmental performance and promoting sustainable consumption; however, consumer acceptance of eco-labeled batik remains poorly understood. This study examines the strengths, weaknesses, opportunities, and threats (SWOT) associated with the adoption of eco-labels in the batik industry from the perspective of consumers in Jakarta. The analysis explores how environmental awareness, cultural identity, purchasing behavior, and sustainability concerns influence consumer perceptions toward eco-labeled batik products. The findings indicate that eco-labels can enhance consumer trust, product differentiation, and market appeal, particularly among younger consumers who are increasingly concerned about environmental and social issues. However, challenges remain regarding consumer understanding of eco-labels, higher product prices, limited information transparency, and the risk of greenwashing. Opportunities are supported by increasing sustainability awareness, government initiatives promoting environmentally friendly batik production, and the growing influence of digital marketing channels. Meanwhile, competition from fast fashion products, limited standardization of eco-label certification, and economic uncertainty pose significant threats. The study suggests that integrating eco-label certification, sustainability communication, and digital traceability mechanisms can strengthen consumer confidence and increase market acceptance of environmentally responsible batik products. These findings provide practical insights for policymakers, industry stakeholders, and batik producers seeking to promote sustainable consumption and enhance the long-term competitiveness of Indonesia’s batik industry.
