Abstract

The implementation of Performance Grade (PG) asphalt specifications has become increasingly important for supporting pavement construction and maintenance practices that account for the influence of climatic and traffic conditions on asphalt performance. However, the Superpave system requires continuous pavement temperature measurements over a minimum period of five consecutive years, while such data are not yet available on a national scale in Indonesia. This study aimed to determine the appropriate asphalt Performance Grade classification for standard traffic conditions in Indonesia using daily maximum and minimum air temperature data collected from 172 meteorological and climatological stations operated by the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG). Air temperature data were converted into pavement temperatures using the Superpave pavement temperature prediction equations. The maximum pavement temperature at a depth of 20 mm was used to determine the high-temperature performance grade, while the minimum pavement surface temperature was used to evaluate low-temperature performance requirements. The results indicate that most regions in Indonesia require PG 58 asphalt binders, whereas 13 locations require PG 64 binders. These findings suggest that the thermal conditions of Indonesian pavements generally remain within the operational range of PG 58, although several locations experience higher pavement temperatures that necessitate greater resistance to rutting and temperature-related distress. This study provides preliminary information on the spatial distribution of asphalt Performance Grades across Indonesia and may serve as a scientific basis for the development of a national PG map and the broader implementation of performance-based asphalt specifications for sustainable pavement infrastructure management.

Abstract

In the design of elevated bridge structures, the selection of Lead Rubber Bearing (LRB) types plays an important role in controlling seismic response and improving the efficiency of reinforcement requirements in piers. This study aims to analyze the correlation between variations in LRB specifications and the effectiveness of reinforcement in elevated pier structures. The methods used include literature study, three-dimensional numerical modeling, and structural response analysis using SAP2000 software with response spectrum and time-history approaches. The analysis results show that variations in LRB parameters, particularly effective stiffness (Keff) ranging from 0.60 to 0.81 kN/mm and characteristic strength (Qd) ranging from 39 to 80 kN, have a significant influence on the distribution of internal forces within the structure. The use of LRB with lower Keff values was able to reduce internal forces in the piers by approximately ±15–30 percent and significantly decrease longitudinal reinforcement requirements compared to configurations with higher stiffness. In addition, the LRB deformation capacity of 110–140 mm proved effective in enhancing seismic energy dissipation and maintaining the structural capacity-to-demand ratio close to the optimum condition of < 1.0. The contribution of this study demonstrates that optimizing LRB parameters, particularly Keff, can be used as a design strategy to produce pier structures that are more efficient, safe, and economical. These findings provide a technical basis for selecting appropriate seismic isolators to improve the performance of elevated structures under earthquake loads.

Abstract

The COVID-19 pandemic significantly disrupted construction projects worldwide by introducing risks related to occupational health and safety (OHS), workforce availability, and material supply. While previous studies have largely focused on project- and organizational-level impacts, limited empirical research has examined how pandemic-related risks affect individual construction activities. This study investigates pandemic-related risks from an activity-level perspective and proposes mitigation strategies based on evidence from a developing-country context. A descriptive quantitative approach was employed using a questionnaire survey of 112 construction practitioners involved in active projects during the pandemic. Data were analyzed using Mean Score Analysis and the Relative Importance Index (RII) to evaluate the severity of risks affecting construction stakeholders and specific construction activities. The results show that OHS was the most critical risk category (mean = 3.82), followed by labor availability (3.71) and material procurement (3.58). At the activity level, masonry work was the most affected (mean = 3.79), followed by earthwork (3.63) and concrete work (3.49). These findings indicate that pandemic-related risks are unevenly distributed across construction activities, with labor-intensive activities being particularly vulnerable to health restrictions and workforce disruptions. This study extends construction risk management literature by introducing an activity-level assessment perspective and emphasizes the need to integrate health-related risks into conventional risk management frameworks while adopting activity-specific mitigation strategies to improve resilience against future public health emergencies and other large-scale disruptions.

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

Wood charcoal ash is the result of chemical changes from the burning of wood. Wood charcoal contains silica which is a good binder aggregate for concrete mixtures, it is the same as the function of cement in a concrete mixture. Wood charcoal can also be used as a mixture or addition to the manufacture of reactive concrete. Concrete is a mixture of portland cement, fine aggregate, coarse aggregate and water, with or without additives that form a solid mass. Concrete is prepared from coarse aggregate and fine aggregate. Cement and water interact chemically to bind the aggregate particles into a solid mass (George Winter, 1993). Based on the results of research that has been done, the results obtained on normal concrete of 17.98 Mpa at the age of 7 days and increased at the age of 14 days of 20.73 Mpa, and 28 days of 22.94 Mpa. At the time of normal concrete mixed with wood charcoal ash 3% compressive strength of concrete again increased by 20.43 Mpa at the age of 7 days, but at the age of 14 days of concrete with a mixture of wood charcoal ash increased by 20.82 Mpa and again increased at the age of 28 days by 27.07 Mpa. The decrease continued to occur in concrete with a mixture of wood charcoal ash 8% and 13% at the age of 7 Days, 14 days, and 28 days, the increase in the compressive strength of the optimal concrete is in the concrete mixture of wood charcoal ash 3% at the age of 28 days.

Abstract

An earthquake is a natural disaster event that causes seismic waves and vibrations or shocks due to a sudden release of energy under the earth's surface. Earthquakes are caused by collisions or frictions between tectonic plates (earth plates) or the collapse of gaps in the sea. In this study, it is specialized to evaluate the performance of the upper structure by adopting a plan on the existing building structure (existing condition) in accordance with the change in the field due to differences, changes in field conditions and will carry out a non-linear static analysis in the form of pushover analysis using the ATC-40 method with a building that functions as a flat. The results of the pushover analysis in the Rusun Jagakarsa building by modeling using the ETABS application obtained a greater value from the base shear in the y direction compared to the base shear in the x direction. The capacity curve in the x-direction stopped at step 9 with a value from the Base Shear of 48.654,4992 KN, the capacity curve in the direction of y stopped at step 3 withand a Base Shear value of 29.656,6413 KN. The level of performance of the structure was measured based on the calculation of the maximum parameter of total drift and the maximum parameter of inelastic drift of the direction x of 0.00803 < 0.01 value is included in Damage Control (DC). For the maximum parameter value of the total drift resulting from the calculation of pushover in the direction y is 0.00741 < 0.01, based on these results it is included in the category of Immediate Occupancy (IO). Then for the maximum parameter value of inelastic drift as a result of the calculation of Pushover in the direction of y is 0.00745 > 0.005, this value is included in the category of Damage Control (DC).Keywords: Earthquake, pushover, ETABS

Abstract

The construction of the I-Smart Building is planned on a site with steep slope topography, with an elevation difference of approximately 8 meters between the front side (+110.000) and the rear side (+102.000), resulting in a slope gradient of about 4.7%. During the construction phase, the zero elevation of the I-Smart Building had to be adjusted to match that of the previously constructed Technopole building, necessitating soil excavation of up to ±5 meters. This adjustment significantly impacted the structural design, particularly due to the variation in column heights, which led to the short column effect. Short columns are known to experience greater shear forces and bending moments due to concentrated lateral loads, while carrying smaller axial loads compared to taller columns. The analysis showed that short columns received approximately 53% higher shear forces and 83% higher bending moments, but carried only half the axial load of tall columns. Nevertheless, all column types satisfied the requirements for cross-sectional capacity, internal forces, and reinforcement needs. Additionally, the difference in column heights affected the distribution of lateral loads on the floor slabs. However, theoretical calculations and structural analysis indicated that the floor slabs were capable of resisting the resulting internal forces, with reinforcement meeting the requirements of SNI 2847-2019. Overall, both the column structures and floor slabs were deemed safe and met design criteria.Keywords: Short Column, Sloped Terrain, Slab, Sloping

Abstract

Indonesia, as a strategic global maritime axis, has only 7.03% of its islands equipped with jetties, and jetty construction poses environmental challenges due to emissions and ecological impacts. Green retrofitting provides a sustainable solution by improving energy efficiency in existing jetties. The Envision rating system guides the transition from conventional to green infrastructure, assessing quality of life, leadership, resource allocation, natural environment, and climate resilience. Despite its benefits, 32% of green projects experience delays. This study analyzes the key factors influencing time performance optimization in Green Retrofit Jetty projects using Lean–Value Stream Mapping (VSM). Using SEM-PLS, ten critical factors were identified. Lean–VSM facilitates process visualization and waste elimination. The Green Retrofit Jetty, achieving an Envision Platinum rating, reduced project duration from 250 to 220 days, demonstrating a 12% improvement in time performance while supporting efficient and sustainable jetty development.
