Abstract

Bengkulu Province, located along the western coast of Sumatra, is one of Indonesia’s most seismically vulnerable regions due to its proximity to major tectonic boundaries. This study aims to enhance earthquake-resilient infrastructure planning by developing a two-dimensional geospatial model of key geotechnical parameters—Plasticity Index (PI) and water content (ѡ) —in the coastal zone. A total of 65 geotechnical observation points served to generate detailed maps by using the Inverse Distance Weighting (IDW) method down to 30 meters depth. The model integrates empirical correlations with statistical and spatial analyses to overcome the challenges of limited data. Results highlight distinct geotechnical variations across different soil layers and administrative regions, revealing zones with high liquefaction potential. The findings provide insight for engineers, urban planners, and disaster risk authorities in designing site-specific construction strategies. This research fills a critical gap in the current literature regarding Inverse Distance Weighting (IDW)-based geospatial modelling in seismically active areas. It offers a replicable framework for other coastal regions with similar geological contexts. Keywords: Plasticity Index; Water Content; Geospatial modeling; Inverse Distance Weighting (IDW)

Abstract

South Sumatra is a province on the island of Sumatra, positioned along the boundary between the Indo-Australian Plate and the Eurasian Plate. The tectonic interaction between these plates has resulted in a mountain range that extends longitudinally from the island’s northern to southern regions, a geological condition that contributes to the area’s susceptibility to natural hazards, one example is the Dempo Volcano. This study uses the four-step model method to analyse the vulnerability of the road network on evacuation routes during the eruption of Dempo Volcano in Pagar Alam City. Eight road sections were observed. A comparison of traffic survey results and numerical modelling was conducted to assess the consistency of the model and also to predict critical conditions. Scenario 1 represents evacuation conditions without any changes to road geometry, while Scenario 2 represents evacuation conditions with modifications in the form of road widening. The analysis showed that most of the population prefers motorcycles as a mode of transport and the fastest route during evacuation, considering the faster evacuation time. Scenario 1 showed a surge in traffic volume, which became an obstacle to evacuation. Scenario 2 can increase capacity and improve traffic flow. The Vulnerability Index indicates that some road sections are vulnerable to evacuation impacts. Keywords: Disaster Evacuation; Four Steps Models; Dempo Volcano Eruption; Road Network Modelling; Vulnerability Index.

Abstract

In the landslide–prone terrains of Puri District, East Java, engineers have crafted a groundbreaking solution to a life–threatening problem: a hybrid retaining wall that fuses traditional batu kali masonry with reinforced concrete, designed to outlast both relentless soil creep and violent earthquakes. Standing 4.25 meters tall and stretching 20 meters across a fragile slope, this structure—embedded 1.5 meters into the earth—defies seismic forces amplified by climate change, withstanding horizontal accelerations of 0.19g and shear forces that spike 388% during quakes. Rigorous analysis reveals its secret: D16 steel bars, spaced as tight as 100 mm at stress hotspots, work in concert with locally quarried stone to balance cost and resilience. The wall’s success lies in numbers—sliding safety factors of 4.02 (normal) and 1.78 (seismic), bearing pressures grazing 99.9% of limits without failure—but its true victory is human. Shielding a riverside community from catastrophic landslides, it ensures roads stay open, homes remain intact, and daily life flows uninterrupted. As Indonesia battles rising rainfall and tectonic unrest, this innovation offers a replicable blueprint: marrying ancestral building wisdom with 21st–century engineering to turn vulnerability into durability. Keywords: Retaining Wall; Seismic Condition; Landslide Mitigation; Masonry Structure; Sustainable Infrastructure.

Abstract

Building Information Modelling (BIM) has emerged as a transformative methodology within the Architecture, Engineering, and Construction (AEC) sector, significantly changing the approach to project planning, execution, and management. This study presents a narrative literature review (NLR) of BIM, focusing on its theoretical foundations, implementation benefits, and the key barriers to its adoption. The objective is to identify and synthesize the core concepts that define BIM's maturity levels, level of development (LOD), and the use of a common data environment (CDE) within the construction industry. The literature search was conducted using Google Scholar, with keywords such as "Building Information Modelling," "BIM benefits," "BIM barriers," and "BIM theory." The findings indicate that BIM offers significant advantages in enhancing design quality, facilitating collaboration, improving cost estimation, promoting sustainability, and optimizing lifecycle management. However, its implementation faces challenges, including high initial investment, lack of skilled professionals, interoperability issues, and organizational resistance. A case study on a residential building project was also included to illustrate the practical application of 3D, 4D, and 5D BIM. This review concludes with recommendations to enhance BIM adoption through standardization, training, supportive policies, and promoting its role in sustainable construction. Keywords: Narrative Literature Review (NRL); BIM maturity; Level of Development (LOD); Common Data Environment (CDE); BIM barriers.

Abstract

Reinforced concrete plays a crucial role in structural systems by providing strength and stability to buildings. Recent advancements in construction technology have introduced bamboo as an alternative reinforcement material to steel, due to its relatively high tensile strength (up to 253 MPa). However, bamboo's high cellulose content increases its vulnerability to fire. During building fires, structural elements may be exposed to temperatures between 800–1000°C for up to one hour. This study aims to investigate the effect of elevated temperatures on the axial load capacity and strain behavior of bamboo-reinforced concrete columns. Two reinforcement types were tested: (1) intact round bamboo with spiral steel stirrups, and (2) slatted bamboo with rectangular steel stirrups. All specimens were made using 25 MPa concrete with dimensions of 15×15×60 cm, and were exposed to 800°C for one hour before testing. Results showed that the round bamboo column with spiral stirrups sustained a maximum axial load of 247.6 kN (4.67% lower than analytical predictions and 59.83% lower than pre-fire values). The slatted bamboo column with rectangular stirrups held 233.2 kN (4.18% lower analytically and 61.78% lower than pre-fire values). Axial and lateral strain values varied slightly between specimens. This research highlights the structural viability of bamboo reinforcement under high-temperature exposure. Keywords: High Temperature Effect; Concrete Column; Bamboo Reinforced Concrete.

Abstract

This study evaluates the quantity and operational costs of heavy equipment in the Wulan River Revitalization Project (CWP–3DJK) across Demak, Kudus, and Jepara, aiming to identify factors hindering efficiency and performance. Using a mixed–methods case study (quantitative analysis, field observations, interviews, and document reviews), results show Excavator productivity dropped 14.3% from theoretical standards (12.67 m³/hour vs. 14.57 m³/hour), mainly due to 22% non–technical downtime from heavy rainfall, excessive sedimentation, and social conflicts. Operational costs exceeded the budget by 12.5% (Rp. 14.8 billion), driven by fuel (42%) and emergency maintenance on muddy terrain. Equipment imbalance (4 Excavators vs. 11 dump trucks) caused loading queues, reducing dump truck efficiency by 18%. Constraints included technical (sedimentation), environmental (rainfall), and social (protests), with social factors contributing 18% downtime—often overlooked in past studies. Recommendations include swamp–type excavators, 10–15% contingency funds in the Budget Plan (QS), and community dialogue forums to reduce conflicts. Practical benefits include improved budget efficiency (<5% deviation), reduced social downtime, and IoT–based real–time monitoring. Findings emphasize the need for an integrated approach combining technical, environmental, and community participation to ensure sustainable infrastructure project success in Indonesia. Keywords: Heavy Equipment; Operational Costs; River Revitalization; Productivity; Project Management.

Abstract

Nusantara Capital City (IKN), designated as Indonesia’s new capital under Law Number 3 of 2022, is envisioned as a sustainable, eco-friendly forest city; consequently, strategic infrastructure such as the KKT Kariangau–Sp. Tempadung Toll Road (IKN Toll 3B) must strictly comply with green standards, yet empirical evaluation of its actual on-site construction performance remains highly limited. Implementing Green Road Construction is vital to reducing environmental impacts and strengthening sustainability commitments. This study evaluates its performance using the Importance Performance Analysis (IPA) method, based on responses from 42 participants comprising service users, providers, and supervising consultants. Results show an average importance score of 4.42 and a performance score of 4.17. Most indicators fall into Quadrant II (Maintain Performance), while energy-efficient lighting and excess material use fall into Quadrant I (Top Priority). Indicators related to energy, water, and materials are in Quadrant III (Low Priority), and none are in Quadrant IV. Overall, the implementation is satisfactory, with recommendations to enhance energy efficiency and material management to support sustainable toll road development in IKN further Keywords: Green Road Construction; Toll Road; Importance Performance Analysis (IPA); Sustainability; Nusantara Capital City (IKN).

Abstract

This study investigates the effect of bracing-shape variations—specifically Z-braces and X-braces—on the energy dissipation capacity of cold-formed steel (CFS) portal frames under cyclic loading. The research was conducted experimentally at the Structural Engineering Laboratory, Department of Civil Engineering, Universitas Negeri Malang, using hollow box CFS profiles (G550 grade, 40×40×0.3 mm). Three configurations were tested: non-braced (No-Brace), X-braced, and Z-braced frames. Cyclic static loading was applied in accordance with ASTM E2126-11 to evaluate lateral strength, energy dissipation, and failure mechanisms. The results show that adding bracing significantly increases lateral load capacity compared to the unbraced frame. The X-brace specimen demonstrated the highest lateral strength of 1.808 kN, nearly double that of the No-Brace configuration (0.898 kN), followed closely by the Z-brace (1.825 kN). In terms of energy dissipation, the X-brace achieved the highest value of 743.61 kN·mm, approximately 79.5% higher than No-Brace and 165.7% higher than Z-Brace, indicating superior hysteretic performance. Structural failures primarily occurred at screw joints due to cyclic shear and pull-out effects. Overall, the study concludes that X-brace configurations provide the most effective enhancement in both lateral stiffness and seismic energy dissipation capacity for cold-formed steel portal frames. At the same time, Z-braces exhibit better ductility but lower energy absorption efficiency. These findings are expected to contribute to the design of lightweight, earthquake-resistant cold-formed steel structures. Keywords: Cold-formed steel; Bracing configuration; X-brace, Z-brac; Cyclic loading; Energy dissipation; Structural performance.

Abstract

Serviceability performance is crucial for reinforced concrete (RC) structures to ensure durability, functionality, and user comfort. While existing research often focuses on individual components, integrated evaluations of complete slab-beam floor systems using practical finite element analysis (FEA) in accordance with Eurocode 2 remain limited. This study evaluates the short-term and long-term serviceability performance of a typical RC floor system (top/bottom slabs, main/secondary beams) under service loads. A 3D finite element model was developed using SAFE software, with crack-width and deflection verifications conducted in accordance with Eurocode 2 (EN 1992-1-1) and Eurocode 0 (EN 1990). The numerical results confirm that all structural components satisfy the prescribed serviceability limits: Maximum Crack Width, measured at 0.085 mm for the main beam and below 0.22 mm for the slabs, both well within the 0.30 mm allowable limit. Maximum Long-Term Deflection: Reached 27.6 mm for the main beam, remaining below the 34.0 mm allowable limit. The FEA successfully captured realistic slab-beam interactions and internal force redistributions, providing structural engineers with practical, code-compliant guidance. Keywords: Reinforced Concrete; Serviceability Limit State; Crack Width; Deflection; Eurocode 2; FEM.

Abstract

Project construction bridge own risk safety and health high work safety (K3). However, the empirical relationship between the implementation of the Occupational Health and Safety Management System (OHSMS) and workers' productivity in Indonesia, especially in remote infrastructure project areas, has not yet Been Widely researched. This research analyzes the impact of implementing SMK3 on workers' productivity during bridge construction in North Maluku Province. Approach quantitative, with an explanatory design survey used. Data collected from 40 respondents using a 5-point Likert-scale questionnaire were analyzed using multiple linear regression. Five independent variables examined: K3 regulations and procedures (X1), communication workers (X2), competent workers (X3), environmental work (X4), and workers' involvement in K3 (X5). The results of the F test show that the fifth variables are, in a way, simultaneously influential on productivity among workers (F = 16.443; p < 0.05). The coefficient of determination (R² = 0.574) indicates that the model explains 57.4% of the variation in productivity. Competence worker become the most dominant factor (β = 0.307; t = 3.744; p = 0.001), followed by involvement worker in K3 (β = 0.267) and the environment work (β = 0.222). Keywords:​ System K3 Management; Productivity Workers; Project Construction Bridge; Competence Workers; Involvement of Workers.
