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

Jalan Gading Kirana Timur, North Jakarta, experienced significant flooding problems due to an inadequate drainage system. This study aims to analyze the performance of the drainage pipeline network using EPANET v.2.0 software and compare the simulation results with manual calculations. Quantitative descriptive methods are used to collect data through literature studies and field surveys. The results of the analysis showed that the flow speed in the pipeline was above the set minimum limit, but the headloss value reached 19.38 m/km, far exceeding the maximum limit of 10 m/km. This indicates that water cannot flow properly to the disposal site, potentially causing inundation and flooding. Manual calculations and EPANET simulations show consistency in total head and headloss, with total heads at junction 2 being 32.07 m. Recommendations for improvements include increasing pipeline capacity to reduce headloss and the use of EPANET as an aid in planning more effective drainage systems. This research is expected to provide input for the community and the government in flood mitigation efforts on Jalan Gading Kirana Timur, North Jakarta.Keywords: flooding, drainage system, EPANET.

Abstract

Landslides often occur unexpectedly, even on slopes previously considered stable according to standard methods, but in reality, the slopes fail. This study presents a method for landslide analysis and mitigation using the concept of cracked soil that considers hidden subsurface cracks as the main triggering mechanism under heavy rainfall conditions. A case study was conducted at the 150 kV SUTT tower site in Segoromadu-Petrokimia, Gresik, Indonesia, where slope failure was observed near critical infrastructure. Comprehensive field investigations, including Standard Penetration Tests (SPT), geoelectric surveys, and laboratory testing have revealed a predominantly stiff clayey silt soil profile with potential cracks between 4–7 meters deep. Slope stability was analyzed using the Limit Equilibrium Method (LEM) under critically saturated and undrained conditions and modeling a weak layer indicated as a cracked layer. The layer was obtained from the interpretation of geoelectrical testing results in the field. The results confirmed that the existing safety factor was below the recommended threshold, especially when considering the tower load. To restore stability, a reinforcement design using mini-piles combined with concrete overlays and sheet piles was proposed. Post-reinforcement analysis showed an overall stability factor exceeding 1.5, validating the design's effectiveness. This study highlights the importance of accounting for subsurface cracks in analyzing slope failure mechanisms to provide mitigation solutions best suited to field conditions.Keywords: Landslide, Cracked Soil Theory, Slope Stability, LEM Analysis

Abstract

Jakarta is facing a clean water crisis due to rapid population growth, land subsidence, and fluctuations in the supply of PDAM. This study analyzes the potential application of Artificial Aquifer Storage Rainwater (ABSAH) technology as an alternative solution for providing clean water in densely populated residential areas. The study was conducted in Gading Kirana RW 08 Housing, Kelapa Gading, North Jakarta, with an area of 42 hectares. The research method includes the analysis of BMKG rainfall data at the Tanjung Priok Maritime Meteorological Station for the period 2016–2025, the calculation of the volume of rainwater availability from a roof area of 252.000 m², the analysis of domestic water needs based on SNI 6728.1:2015 (200 liters/person/day), and the planning of the ABSAH system with a depth of 2.5 meters. The results showed that the daily availability of rainwater fluctuated between 2.015,19–9.099,65 m³, while the domestic needs of the community were 1.243 m³/day. The analysis of the water balance shows that there is an annual surplus of 33.159,79 m³ that can be utilized through the ABSAH system. The implementation of the system requires 173 units of ABSAH tubs with a capacity of 150 m³ with dimensions of 12 m × 5 m × 2.5 m, serving a ratio of 7 houses per unit. The ABSAH system integrates rainwater storage, artificial recharge, and flood mitigation functions to support urban water resilience. This study provides a model for the implementation of ABSAH technology for similar residential areas and contributes to the achievement of SDGs related to sustainable clean water access.Keywords: ABSAH, rainwater harvesting, artificial aquifers, urban water resilience, North Jakarta

Abstract

Castellated steel beams, produced by cutting solid cross-sections, enhance the moment of inertia without increasing self-weight but remain vulnerable to lateral–torsional buckling (LTB) and Vierendeel action. This study investigates the nonlinear behavior of IWF 200×100×5.5×9 beams with spans of 8–10 meters using ABAQUS and the modified Riks algorithm. Results reveal that LTB is the governing failure mode, consistent with AISC 360 predictions. Circular web openings provide 2–7% higher ultimate capacity at short spans, though their performance aligns with hexagonal openings for longer spans. Hexagonal openings, however, reduce deflections by 15–20%, indicating improved serviceability. Strengthening strategies are proposed, including stiffeners, lateral bracing, partial closure of web openings near supports, and optimization of opening ratios between 50–70%, achieving an effective balance between strength and deflection control. The findings highlight the critical influence of opening geometry and span on structural performance and provide actionable guidance for the design and optimization of castellated steel beams. This work advances understanding of perforated steel behavior under bending and offers practical solutions for enhancing both ultimate capacity and serviceability in engineering applications.Keywords: Castellated steel beams, nonlinear analysis, lateral–torsional buckling, ABAQUS, structural optimization

Abstract

Traditional markets are characterized by direct retail transactions between sellers and buyers, operating on either a temporary or permanent basis with specific service levels. Perumnas Klender Market represents one of the prominent traditional markets in Jakarta. High levels of commercial activity during peak hours frequently result in significant vehicle accumulation within the market's parking facilities. Consequently, parking management has become a critical factor in maintaining the functionality of traditional market infrastructure. This research aims to evaluate the parking characteristics and performance for motorcycles and private vehicles. Primary data were collected through field surveys and analyzed using the parking characteristic formulations established by the Directorate General of Land Transportation’s technical guidelines. The findings indicate that the current parking area is insufficient to accommodate the volume of vehicles, primarily due to limited space and irregular parking behavior among visitors. Analytical results show a parking index exceeding 100%, signifying that vehicle demand surpasses the available capacity. By implementing the proposed alternatives, the parking index can be effectively reduced to a more sustainable level.Keywords: Traditional Market, Parking Performance, Parking Index, Parking Characteristics, Parking Accumulation
