Abstract

Steel construction contributes significantly to global carbon emissions and energy consumption. In response to sustainability concerns, circular economy principles offer a promising approach to reducing waste, maximizing material reuse, and minimizing environmental impact. This study presents a systematic literature review of 317 Scopus-indexed articles published between 2010 and 2024. The selection focused on reputable journals (Q1–Q4), environmentally friendly steel structures, reuse, and life cycle assessment (LCA). Bibliometric and keyword mapping analysis using VOSviewer revealed that the topic of steel structure reuse and sustainability is still fragmented. Design for Deconstruction (DfD) practices were found to reduce emissions by up to 70% compared to new structures but face practical limitations due to technical and economic challenges. Moreover, the reuse of industrial by-products such as steel slag and blast furnace gas shows high potential for energy savings and CO₂ reduction, although adoption remains limited. These findings highlight the need for innovative joint design, technological integration, and policy incentives to advance circular economy implementation in steel construction.

Abstract

Digital construction has become an important strategy in promoting the Sustainable Development Goals (SDGs) set by the United Nations, especially in the context of infrastructure development. The purpose of this research is to discuss the development of Energy Harvesting (EH) technologies that have been investigated in infrastructure to date. By utilizing energy in the surrounding environment, EH technology offers great potential in reducing carbon emissions generated by infrastructure systems.  This study employs the Systematic Literature Review (SLR) method, involving a structured process of literature search in the Scopus database, selection based on abstracts and content relevance, and in-depth analysis of 27 qualified articles. This research discusses five of the most common EH technologies, namely photovoltaic, piezoelectric, thermoelectric, Wind Energy Conversion System (WECS), and Wind Energy Converter (WEC) technologies. Each technology was evaluated based on its application in infrastructure with a focus on the efficiency and effectiveness of the application of the technology. The results indicate that Photovoltaic and Piezoelectric technologies are the most ready for short-term implementation, while Thermoelectric and WEC technologies show strong long-term potential despite facing technical and economic challenges. Hybrid combinations of multiple technologies have also been proven to enhance efficiency compared to single systems. The harvested energy can be utilized for various infrastructure needs, such as street lighting and Structural Health Monitoring (SHM) systems. This study recommends the application of hybrid technologies as a more efficient solution, tailored to the characteristics of the location and type of infrastructure. In addition, policy support and incentives are needed to accelerate the adoption of these technologies. By implementing these strategies, the construction industry can significantly contribute to achieving the UN's 2030 agenda for sustainable development.

Abstract

Industrial Wastewater Treatment Plants (WWTPs) are essential infrastructures for managing industrial waste, maintaining environmental quality, and protecting public health. However, high concentrations of organic and chemical contaminants increase energy demand, particularly for pumping and treatment processes, contributing to indirect greenhouse gas emissions. This study aims to develop a simulation model to assess operational and financial risks in industrial WWTPs. The framework focuses on the linear relationship between technical and financial variables under uncertain conditions, analyzed using Monte Carlo simulations. Variability in wastewater discharge and quality from multiple industrial tenants introduces technical risks that affect process efficiency, operational costs, and compliance with environmental standards. Key input variables, such as discharge volume, BOD/COD concentrations, and energy and chemical prices, are modeled as probability distributions. The simulation generates probabilistic outputs of operational costs and potential penalties. This approach enables systematic analysis of uncertainty and supports more effective, data-driven decision-making in WWTP management.

Abstract

Toll Road Investment is a key strategy in transportation infrastructure development aimed at improving connectivity, logistics efficiency, and economic growth. However, financing complexity, regulatory uncertainty, and socio-political risk dynamics make this investment face serious challenges. Twenty scientific articles published in Q1–Q3 between 2019–2024 were evaluated based on their study focus, key findings, geographic context, and journal rankings. The research results indicate that toll road investment trends are undergoing a significant transformation, marked by the dominance of Public–Private Partnership (PPP) schemes, the integration of digital technology, and a lifecycle-based management approach. Meanwhile, the key challenges identified include a weak regulatory framework, financial risks, limited government capacity, and minimal stakeholder involvement. Conversely, opportunities can be leveraged through strengthening project governance, utilizing innovative contract models, and adopting risk- and sustainability-based performance evaluation systems. These findings are expected to provide theoretical and practical contributions to academics, policymakers, and investors in designing more adaptive and sustainable toll road investment strategies in the future

Abstract

The increasing global challenges of waste accumulation, energy transition, and climate resilience have positioned Waste-to-Energy (WtE) systems as an important pathway for sustainable resource recovery. However, the complexity and uncertainty of WtE processes require advanced modeling approaches capable of capturing nonlinear relationships and improving predictive accuracy. Machine Learning (ML) has emerged as a promising tool for optimizing WtE operations; however, existing studies remain fragmented and are largely focused on technical performance rather than broader conceptual, methodological, and sustainability dimensions. This study aims to systematically examine the development, trends, methodological characteristics, and research gaps in ML applications for WtE systems. A Systematic Literature Review (SLR) was conducted using the PRISMA framework by analyzing relevant publications indexed in Scopus from 2020 to 2025. From the initial search results, 42 studies were selected for qualitative thematic analysis using structured coding to identify technological domains, geographic patterns, theoretical foundations, and methodological approaches. The findings indicate that ML applications in WtE are predominantly focused on optimization, prediction, gasification, and energy recovery modeling. However, the field remains characterized by geographical concentration, limited theoretical integration, insufficient interdisciplinary perspectives, and inconsistent consideration of governance, policy, and socio-environmental factors. The review highlights that future ML-based WtE research should incorporate stronger theoretical frameworks, improve data diversity, enhance model transparency, and integrate sustainability-oriented assessments. In conclusion, ML provides significant opportunities for advancing WtE systems; however, its transformative potential depends on moving beyond algorithmic accuracy toward holistic, equitable, and context-sensitive sustainability solutions.

Abstract

Pengembangan infrastruktur listrik di Indonesia beroperasi dalam lingkungan regulasi berlapis yang menimbulkan risiko hukum multidimensi di seluruh siklus hidup proyek. Terlepas dari kompleksitas ini, kerangka kerja manajemen risiko yang ada di sektor energi cenderung memprioritaskan dimensi teknis dan operasional, sehingga dimensi hukum secara sistematis kurang dieksplorasi. Studi ini bertujuan untuk memetakan dan menganalisis kategori risiko hukum yang tertanam dalam proyek pengembangan pembangkit listrik di Indonesia yang meliputi pembangkit listrik tenaga uap (PLTU), PLTM, PLTS, PLTA, dan panas bumi, serta untuk merumuskan kerangka kerja manajemen risiko hukum terintegrasi yang sesuai dengan lanskap regulasi sektor tersebut. Pendekatan penelitian hukum normatif diterapkan, yang menggabungkan pendekatan undang-undang, konseptual, dan studi kasus. Data dikumpulkan melalui penelitian pustaka sistematis dari sepuluh jurnal peer-reviewed yang terindeks di SINTA dan Scopus (2021–2025), serta sumber hukum primer termasuk undang-undang Indonesia tentang kelistrikan, perlindungan lingkungan, pengadaan lahan, dan kesehatan dan keselamatan kerja. Enam tipologi risiko hukum utama berhasil diidentifikasi: risiko perizinan dan lisensi, risiko kontraktual, pengadaan lahan dan risiko pengadaan lahan, risiko kepatuhan K3, risiko kepatuhan lingkungan dan AMDAL, serta risiko regulasi energi yang dinamis. Keenam tipologi ini saling terkait dan berpotensi memperburuk satu sama lain jika tidak dikelola secara terintegrasi. Metode analisis AHP, FMEA, dan FTA ditemukan memiliki keterbatasan struktural dalam menangkap dimensi hukum secara komprehensif. Implementasi manajemen risiko hukum yang sistematis dan terintegrasi melalui uji tuntas hukum, pemantauan berkelanjutan terhadap kepatuhan regulasi, dan mekanisme penyelesaian sengketa yang terstruktur merupakan prasyarat mendasar untuk keberhasilan pengembangan infrastruktur listrik yang berkelanjutan dan efisien di Indonesia.

Abstract

The government is currently encouraging readiness in government projects using the Design & Build project delivery system, as regulated in the Construction Services Law No. 7 of 2017. Design and Build (DB) from various previous literature has been proven to provide advantages compared to Design Bid Build (DBB) including speed of implementation, project risks, design changes and the absence of change orders during project implementation. This study aims to examine what factors influence the partnership of contractors and designers in design and build projects to produce good project performance including cost, quality, time, K3 and environment. The research method used in this study is a quantitative method with 50 respondents and processed through SPSS to explore respondents' perceptions, about factors that are considered to influence the partnership of contractors and designers in Design and Build (DB) projects. The respondents came from contractors and consultants who have worked on government projects with design & build project delivery. The results of this study indicate six key factors influencing contractor–designer partnerships in Design and Build projects, including relationship factors, process factors, and environmental factors, with partnership maturity acting as a moderating variable. These factors contribute to improved project performance in terms of cost, quality, time, safety, and environmental aspects. The findings provide practical insights for contractors and designers in strengthening collaboration and readiness for implementing Design and Build project delivery systems.

Abstract

The high demand for dormitories at Astra Polytechnic will keep rising in tandem with the growing student body. Investment for another tower building is required and also will have an impact on dormitory rental prices. The purpose of this study is to find out the evaluation of the feasibility of building a new dormitory building in terms of financial aspects and to calculate the appropriate dormitory room rental price for the dormitory building using a forecasting method. The research results show that the project is declared financially feasible because the IRR value is greater than the MARR, which is 7.8% > 6.875%, and the payback period is 19.38 years. The results were obtained with an adjusted rental price, where rental rates increase by 10% per year from the second to the fifth year. Following the development of the second dormitory tower in the sixth year, rental prices must increase by 20% annually until the end of the investment period in the 20th year
