Abstract

Infrastructure user safety is a fundamental aspect of civil engineering practice that is closely related not only to technical compliance but also to engineers' moral responsibility toward society. This study aims to analyze the forms, scope, and implications of civil engineers’ moral responsibility in ensuring infrastructure user safety and to identify factors influencing the implementation of professional ethical principles in engineering decision-making. The research employed a quantitative approach using a narrative review method. Data were collected from 35 scientific articles, professional standards, and policy documents published between 2020 and 2025. A data extraction form was used to identify indicators of moral responsibility, ethical compliance, and infrastructure safety. Data analysis was conducted using descriptive quantitative techniques, including frequency, percentage, correlation, and trend analysis. The findings reveal that 88.57% of the reviewed literature identified public safety as the primary priority of civil engineers’ professional responsibility. Furthermore, 82.86% of the sources indicated that ethical violations contribute to an increased risk of infrastructure failure, while 80.00% emphasized the importance of moral responsibility in engineering decision-making. Correlation analysis demonstrated a strong positive relationship between moral responsibility and infrastructure user safety (r = 0.812; p < 0.05). The study concludes that moral responsibility is an essential component of civil engineering practice and plays a significant role in protecting infrastructure users. The findings contribute to the development of engineering ethics theory, public safety policies, and the improvement of civil engineering practices oriented toward public welfare.

Abstract

The construction industry contributes approximately 37–39% of global carbon dioxide emissions and consumes around 36% of total final energy, making it a priority sector in the sustainable development agenda. Green technology in construction offers solutions through the use of low-carbon materials, energy efficiency, and green building certification. However, the adoption of green technology cannot be separated from ethical considerations involving the professional responsibility of engineers, social justice, certification transparency, and respect for local communities. This study employs a conceptual literature-based approach to identify and analyze relevant engineering ethics dimensions in the implementation of green technology in Indonesia's construction sector. The findings indicate that engineering ethics must serve as the primary foundation for every green technology adoption decision, rather than merely fulfilling formal regulatory requirements. This study recommends integrating an engineering ethics framework into Indonesian green construction practice standards.

Abstract

In the studies reviewed, bolted connections in steel structures generally exhibit semi-rigid behavior with a nonlinear moment-rotation response, where the majority of studies report behavior lying between the perfect pin and fully rigid conditions. The authors have not identified a review that simultaneously synthesizes rotational stiffness, bolt slip effects, and implications for SNI 1729:2020 within a single integrated framework; similar reviews in the Indonesian standards context remain scarce based on searches across Scopus, ScienceDirect, and Google Scholar. This study presents a systematic literature review following the PRISMA 2020 protocol (Page et al., 2021), examining 13 selected studies from 75 identified articles (search conducted 15–20 June 2026). The 2017–2025 timeframe was selected to capture recent developments in nonlinear analysis and FEM of bolted connections. Quality assessment using an internal scoring instrument adapted from JBI principles yielded scores ranging from 2 to 5 out of 5, reflecting realistic methodological quality variation. Qualitative synthesis reveals a consistent tendency that increasing end-plate thickness produces a significant increase in initial rotational stiffness, accompanied by a moderate-to-significant reduction in rotation capacity. Neglecting bolt slip was found to tend toward significant displacement prediction errors near ultimate capacity. Comparison of SNI 1729:2020 and Eurocode 3 identifies three aspects not yet explicitly accommodated in SNI 1729:2020, potentially addressable through Eurocode 3 component method adoption with Indonesian condition validation.

Abstract

The aviation industry increasingly relies on composite materials to optimize performance and reduce weight in high-speed aircraft structures. These materials offer superior strength-to-weight ratios, corrosion resistance, and design flexibility. Understanding the mechanical properties of composite materials is essential for enhancing the safety and efficiency of high-speed aircraft. This research aims to analyze the strength characteristics of composite materials used in high-speed aircraft structures. The study focuses on evaluating the mechanical properties and performance under various loading conditions to determine their suitability for aviation applications. An experimental approach was employed, involving the fabrication of composite samples using different matrix and fiber combinations. Tensile, compressive, and flexural tests were conducted to assess mechanical properties. Data were collected and analyzed to evaluate the performance of each composite configuration under simulated operational conditions. The findings indicated that hybrid composite materials exhibited the highest strength and stiffness, outperforming traditional materials. The tensile strength of the best-performing composite reached up to 600 MPa, while flexural tests showed significant resistance to deformation. These results highlight the potential of advanced composites to enhance the structural integrity of high-speed aircraft. The research underscores the importance of selecting appropriate composite materials for high-speed aircraft applications.

Abstract

This study investigates the differences in mechanical behavior and stress distribution between two types of bolted steel connections—splice and endplate joints—using the Finite Element Method (FEM). Numerical simulations were conducted with MIDAS FEA NX, employing SS400 structural steel and A325 high-strength bolts to model beam connections subjected to bending loads. The analysis focused on evaluating von Mises stress distribution, deformation behavior, and load transfer mechanisms. Results showed that the endplate connection exhibited higher stiffness —approximately 5% less deflection than the splice connection —but also experienced 9.6% higher local stresses concentrated near the weld and in the outer bolt regions. Conversely, the splice connection exhibited a more uniform stress distribution and greater ductility, enabling controlled local yielding and improved energy dissipation. FEM predictions closely matched analytical beam theory with less than 5% deviation, confirming the accuracy of the numerical model. The findings suggest that endplate joints are suitable for rigid moment-resisting frames, while splice connections are preferable for applications requiring flexibility, fatigue resistance, and ease of assembly.

Abstract

Increasing exposure of infrastructure systems to extreme hazards, aging effects, and climate-induced uncertainties has revealed fundamental limitations of conventional strength- and safety-oriented design approaches. Structural performance can no longer be evaluated solely in terms of damage prevention, but must also account for functionality loss, system interdependencies, and recovery capacity. This study aims to reengineer the concept of structural resilience by developing a multiscale framework that integrates resilience explicitly into performance-based infrastructure design. The research adopts an analytical and framework-oriented methodology, combining critical synthesis of performance-based design theories, structural resilience metrics, and systems engineering concepts. Multiscale linkages are established among component-level behavior, system-level functionality, and network-level performance, with explicit consideration of temporal recovery processes. The results demonstrate that resilience is an emergent and time-dependent system property that cannot be inferred directly from component-level performance indicators. Local strengthening strategies are shown to yield limited resilience gains unless supported by system redundancy, connectivity, and recovery-oriented design. The proposed framework reveals hidden vulnerabilities and recovery bottlenecks that remain unaddressed in conventional performance-based approaches. The study concludes that effective resilience-oriented infrastructure design requires a paradigm shift toward multiscale, system-aware, and recovery-informed performance objectives. Embedding these principles into performance-based design provides a robust foundation for enhancing infrastructure reliability, functionality, and societal resilience under extreme and uncertain conditions.

Abstract

Solar energy technology is one of the most rapidly advancing renewable energy solutions aimed at meeting electricity demands in a sustainable manner. This technology converts sunlight into electrical energy through two primary approaches: the photovoltaic (PV) system, which utilizes solar panels to directly transform sunlight into electricity, and the Concentrated Solar Power (CSP) system, which uses mirrors or lenses to concentrate solar heat for electricity generation. The main advantage of solar energy lies in its environmentally friendly nature, as it does not produce carbon emissions or harmful greenhouse gases. Moreover, solar energy is derived from the sun—a renewable and abundant source that will not deplete. Economically, solar technology offers long-term cost efficiency; after the initial installation, operational costs are relatively low and can significantly reduce or eliminate electricity bills. The versatility of solar applications is another key benefit, as it can be used for various needs, ranging from household systems to large-scale industrial projects. With these advantages, solar energy stands as a strategic alternative in supporting the transition toward a cleaner, more sustainable energy system and environmentally friendly, especially within the environment of Mpu Tantular University in Jakarta.

Abstract

Soil compaction plays a crucial role in determining the stability of structures, particularly in earthquake-prone regions. Inadequate compaction can lead to soil liquefaction and settlement, increasing the risk of structural failure during seismic events. Understanding the impact of different soil compaction methods is essential for enhancing building resilience. This study aims to evaluate the influence of various soil compaction techniques on the stability of buildings in earthquake-prone areas. It seeks to identify the most effective methods that can improve soil properties and overall structural integrity. A comparative analysis was conducted using laboratory experiments and field tests. Different compaction methods, including static, dynamic, and vibratory compaction, were applied to soil samples. The study measured parameters such as soil density, moisture content, and shear strength to assess the effects of each method on soil stability. The findings reveal that dynamic compaction significantly improves soil density and shear strength compared to static and vibratory methods. Structures built on dynamically compacted soil exhibited greater resilience to seismic forces, demonstrating lower risks of liquefaction and settlement during earthquakes. The research concludes that the choice of soil compaction method is vital for ensuring the stability of buildings in earthquake-prone regions. Dynamic compaction emerges as the most effective technique, providing enhanced soil properties that contribute to structural resilience. Future studies should explore the long-term effects of compaction methods and their implications for building codes and practices in seismic areas.
