Abstract

Office buildings require security systems to ensure comfort, such as fire protection systems, including adequate water supply. This research implements rainwater harvesting as an alternative source for more efficient water resource management and modifies the piping system for hydrants and sprinklers. In this study, a hydrological analysis was conducted based on rainfall data in Bandung City from 2014 to 2024, assessing the water needs for hydrants and sprinklers, as well as analyzing the plans for filtration, pumping, and storage tanks for the rainwater harvesting system. This research utilizes a storage tank with a capacity of 128 m³ and employs Nanotec filtration using FRP filter media, along with a pump capacity of 125-139 m, operating on power ranging from 110-132 kW. The results of the study indicate that the availability of harvested rainwater reaches 55% of the requirements for hydrants and sprinklers.

Abstract

Soft clay soil has low bearing capacity and high compressibility, which can cause structural damage. On the other hand, Expanded Polystyrene (EPS) waste and eggshell waste are abundant and difficult to decompose, making them potential materials for sustainable soil stabilization. This study aims to improve the physical and mechanical properties of soft clay by adding EPS particles at 0.45% of the dry soil weight and eggshell powder at 4%, 8%, and 12%. Soil samples were obtained from Mekarmukti Village, West Bandung Regency, then cured for 0–28 days and tested through water content, specific gravity, standard compaction, unconfined compressive strength (UCS), and California Bearing Ratio (CBR) tests. The results showed that the mixture reduced water content, increased density, and improved soil strength. The optimum composition was achieved with soil + 0.45% EPS + 8% eggshell powder, where the unconfined compressive strength increased from 1.631 kg/cm² to 2.662 kg/cm², the unsoaked CBR increased from 2.201% to 4.659%, and the soaked CBR reached 1.458%. The mixture produced lighter, more stable, and easily compacted soil, and is recommended as an environmentally friendly stabilization material for lightweight embankments, bridge approaches, and construction on soft ground.

Abstract

Bridges are vital infrastructure that require feasibility evaluation before being used to ensure user safety. Feasibility assessment can be done through dynamic and static tests. The dynamic parameters used are natural frequency and damping ratio, while static parameters include deflection and strain during loading. This study conducted forced vibration tests and static load tests on the Batang Toru-4 Bridge. The vibration test results showed a natural frequency of 3,248 Hz, lower than the minimum limit of 3,357 Hz according to Bina Marga empirical data, but still above the British Standard, and a damping ratio of 7.636%, indicating an indication of excessive energy dissipation which is generally due to defects in the structure. However, the static test showed a maximum deflection at 100% UDL of 11.9 mm, still far below the permissible limit of 50 mm. The residual deflection ratio was also only 0.044, still below the permissible limit of 0.2. Therefore, with these results, the bridge was declared functionally fit, but it was recommended to conduct further checks to ensure that excessive damping was not caused by structural damage. The calculated relative capacity is approached by a more conservative dynamic load test compared to a static load test, so that the dynamic load test is an alternative test with a relatively faster time, easier and more conservative results compared to the static load test.

Abstract

This study evaluates the structural performance of a four-story sports center and parking building in South Sumatra designed using a Special Moment Frame System (SMFS). The building has a total height of 17.55 m, with reinforced concrete structures on floors 1–3 and a steel H-beam system on the fourth floor. The materials used are 30 MPa concrete and 420 MPa reinforcing steel. Structural analysis was performed using STAAD.Pro V8i with the response spectrum method in accordance with SNI 1726:2019, considering site class SE and seismic parameters SDS = 0.434 g and SD1 = 0.363 g. The applied load combinations include gravity and seismic loads in both principal directions. The results show that the maximum interstory drift in X and Y directions is well below the allowable limits, and the structure satisfies the Strong Column–Weak Beam requirement (ΣMnc ≥ 1.2 ΣMnb), ensuring ductile seismic behavior. Design comparison indicates several construction-driven modifications, including changes in column cross-sections and the use of steel framing at the fourth floor, which were verified to remain compatible with the overall structural system. Overall, the structure demonstrates adequate seismic performance and code compliance.

Abstract

Ketapang Regency, West Kalimantan, is one of the regions with intensive industrial activity, particularly bauxite mining and coal-fired power plants (CFPPs), which generate large amounts of industrial waste such as bauxite tailings, red mud, fly ash, and bottom ash. To date, most of this waste has not been optimally utilized and has the potential to cause environmental issues. This study aims to conduct basic physical characterization of the four types of waste and assess their potential for utilization in concrete construction for sustainable transportation infrastructure. The methodology employed includes testing for moisture content, particle size distribution, bulk density, specific gravity, water absorption, and clay content. Test results indicate that fly ash exhibits pozzolanic properties, bauxite tailings have potential as an alternative fine aggregate, bottom ash approaches sand gradation though it requires preliminary treatment, while red mud is more suitable for use as a filler or cement substitute in limited quantities after chemical stabilization. These findings indicate that the utilization of industrial waste in Ketapang can serve as a strategic solution in supporting environmentally friendly infrastructure development while reducing dependence on conventional natural resources.

Abstract

Understanding how pavement surface conditions influence operating speed is essential for improving road safety and optimizing urban traffic performance. This research investigates how pavement surface deterioration represented by the Surface Distress Index (SDI) influences vehicle operating speeds along Kolonel Sudiarto Street, a key urban roadway in Tegal City. A quantitative descriptive method was employed, in which pavement conditions were evaluated using the SDI framework, and vehicle speeds were obtained through space mean speed (SMS) measurements. A total of 358 vehicle samples were examined through simple linear regression to quantify the influence of SDI on motorcycle and passenger car operating speeds. The findings reveal a strong and statistically significant negative association between SDI and motorcycle speed (R² = 0.947), demonstrating that higher levels of pavement distress markedly decrease motorcycle operating speeds. In contrast, the relationship between SDI and car speed is weak and not statistically significant (R² = 0.064), suggesting that car speeds are influenced more by traffic dynamics and vehicle stability than by pavement surface deterioration. Combined regression simulations further demonstrate that motorcycles are markedly more sensitive to incremental surface distress. These findings affirm the relevance of SDI as a key indicator for evaluating pavement performance and predicting speed behavior, emphasizing the need for timely maintenance interventions to support safer and more efficient urban road operations.

Abstract

Quantity take-off (QTO) calculation is an important component in cost estimation and material control in construction projects. Manual methods based on 2D drawings and Bill of Quantities (BOQ) are prone to inconsistencies due to the global volume addition approach and do not always follow the actual geometric cuts. This study compares the results of QTO based on Building Information Modeling (BIM) using Tekla Structures with manual BOQ on the structural work of the Tegal City Public Service Mall Building. The analysis focused on three materials: concrete, formwork, and reinforcement including foundation elements, beams, columns, slabs, and stair slabs. The results show that the total BIM volume produces 1,989.49 m³ of concrete, 6,857.70 m² of formwork, and 302,817.10 kg of reinforcement, while the BOQ recorded 2,025.37 m³, 7,305.17 m², and 303,502.10 kg. The deviations were 1.77%, 6.13%, and 0.23%, respectively. The differences were mainly influenced by automatic geometry truncation in the 3D model, the separation of specific elements such as pitlift walls, and inconsistent reinforcement rules (clear span, overlap, and development length) in manual calculations. These findings confirm that BIM-based QTO and BOQ can produce significant quantity differences in some elements, and identify recurring sources of deviations that can be used as a basis for quantity audits and improve calculation consistency across similar projects.

Abstract

Mahar Martanegara Road in Cimahi City serves as a strategic urban corridor connecting Cimahi and Bandung, characterized by high traffic volume influenced by surrounding industrial, residential, and commercial land use. The volume-to-capacity ratio approaching saturation conditions has increased traffic conflicts and accident risks in recent years. This study identify and analyze accident prone locations (blackspots) along Mahar Martanegara Road using the Equivalent Accident Number (AEK), Upper Control Limit (UCL), and Upper Control Boundary (BKA) methods. Accident data from 2022–2024 obtained from PT Jasa Raharja were analyzed and segmented per 300 meters. The AEK was calculated using weighted severity values for fatalities and injuries, and the results were statistically evaluated using BKA and UCL thresholds. The analysis indicates that two road segments categorized as blackspots is STA 0+600–0+900 and STA 2+400–2+700. The AEK values for these segments are 27 and 33, respectively, exceeding the BKA value (25.69) and their corresponding UCL values STA 0+600–0+900 (23.99) and STA 2+400–2+700 (24.94). These findings suggest systematic accident patterns beyond normal statistical variation. Contributing factors include high traffic density, the presence of heavy vehicles, roadside activities, inadequate safety facilities, and geometric and operational constraints. The results provide a data driven basis for local government intervention through traffic engineering improvements, enhancement of road safety facilities, regulation of heavy vehicle movement, and integrated road safety management strategies.

Abstract

The development of passive telecommunications infrastructure (IPT) plays an important role in supporting digital transformation and urban spatial planning. However, in Bandung City, underground cable excavation works as part of IPT development not only cause traffic disruption during implementation but also frequently degrade road pavement quality due to restoration processes that do not comply with technical standards. This study aims to evaluate the level of conformity of cable excavation manhole restoration in Bandung City with road construction regulations. The evaluation employs a conformance-based approach using a scoring technique applied to six technical indicators: the gap between the cover and frame, the presence of utility identification, the condition of the cover material, surface depressions or protrusions, surface uniformity, and elevation relative to the roadway. A total of 82 manhole locations across 16 road segments were observed to assess field restoration conditions. The results indicate that 84,14% of the locations fall into the “fair” category, 10,98% into the “poor” category, and only 4,88% meet the “good” category. These findings suggest that most post-excavation road restorations have not met the required technical standards, particularly with respect to surface evenness and utility identification. Such conditions affect safety risk levels and pavement performance. Therefore, consistent supervision and improvements in restoration quality are required to ensure that IPT development aligns with the principles of safety and sustainability of road infrastructure.

Abstract

Enclosed High Temperature Flaring Systems (EHTFS) are employed to control gas emissions through high-temperature enclosed combustion; however, structural modifications such as flare stack heightening may alter dynamic characteristics and induce environmental vibration problems. This study evaluates vibration responses induced by EHTFS operation and investigates the mechanisms of vibration amplification and resonance affecting surrounding structures. Field measurements were carried out using three-axis accelerometers installed on the flare stack, supporting structures, soil, and nearby residential buildings during flaring events. Structural dynamic properties were identified using Operational Modal Analysis (OMA) based on the Stochastic Subspace Identification (SSI) method, combined with an assessment of soil–structure interaction. The results show dominant vibration frequencies of 6.1–6.2 Hz, where the natural frequencies of the flare stack and nearby houses are closely spaced. Peak acceleration at residential buildings reached 0.149 m/s², approximately twice that at the source (0.074–0.077 m/s²), indicating significant amplification. Soil investigation revealed shear-wave velocities of 168–257 m/s with relative dynamic amplification factors up to 1.0. Although soil–structure interaction influences wave propagation, the observed amplification is primarily attributed to low-frequency resonance between operational excitation and structural natural frequencies. Increasing flare stack stiffness effectively shifts the natural frequency and reduces resonance potential. The proposed integrated OMA–SSI framework provides a reliable basis for vibration mitigation in industrial flaring facilities.
