Abstract

Increased development of community facilities triggers changes in land use that result in less open land for infiltration. This causes run-off and little rainwater is absorbed by the soil. For this reason, it is necessary to make a reservoir in the form of an infiltration well that functions to accommodate and absorb rainwater into the ground slowly. The purpose of this study was to determine the number and point of infiltration wells. The research was conducted at the Kelapa Gading Pumping Building located in North Jakarta. The address of the registered entity is Jl. Gading Mas Timur I No. 17, RT.12 / RW.10, Pegangsaan Dua Village, Kelapa Gading District, North Jakarta City, where the Kelapa Gading Pump Building stands on an area of ± 4,000 m2, has a reservoir with an area of ± 1,955 m2 with supporting buildings in the form: 1. pump building of 160 m2, 2. substation house of 35 m2, 3. transformer house of 75 m2, 4. employee mess of 52 m2, 5. generator house of 75 m2. This research uses survey methods in the form of measurements, interviews, and to obtain the required data. Based on the data and calculation analysis according to SNI 846-2017, a circular infiltration well with a diameter of 1meter and a depth of 2 meters to 2.5 meters can be determined.

Abstract

The Tiong Channel is located on Jalan Tiong Karet Kuningan, South Jakarta, geographically located between 6°13'06.5" South Latitude and 106°49'17.0" East Longitude. On Jalan Tiong often floods when the rainy season arrives. The flood was caused by several factors, one of which was the drainage channel that could not function properly. At several points in the water channel that will lead to the Krukut River there is a lot of plastic waste from residents which causes narrowing of the channel. The non-uniform channel dimensions are also the cause of flooding, there are several channel points that experience narrowing. From the above conditions, it is necessary to do an analysis of flood problems in the Tiong Karet Kuningan Canal area of South Jakarta to find out whether the Tiong Karet Kuningan Canal in South Jakarta can still accommodate water discharge based on rainfall in the last 10 years and whether the Tiong Karet Kuningan Canal in South Jakarta needs to be normalized. Based on the results of manual calculations and the HEC-RAS application, the Tiong Karet Kuningan Canal in South Jakarta cannot accommodate water discharge based on rainfall in the last 10 years of 12.61 m3/s. At point 0 – point 350 it is necessary to normalize by widening the channel to 2 m and increasing the depth/height of the channel to 2 m. and planning of sluice gates on the downstream of the canal.

Abstract

old-formed steel has emerged as a prominent material in modern construction due to its excellent structural performance, cost-effectiveness, and sustainability. Hollow structural sections made of cold-formed steel have garnered significant attention due to their favourable strength-to-weight ratios and versatility in construction applications. In this research, the cross-section of cold-formed steel hollow structural sections will be analysed as a structure that receives a combination of compressive and bending loads. Numerical analysis was carried out using the finite element method with the help of ABAQUS software to obtain the buckling behaviour and cross-sectional capacity. The cold rolled steel regulations in SNI 79712013 or AS/NZS 4600 will be compared with numerical results to see the level of performance of the code in the case of hollow structural sections. Numerical testing and cross-sectional capacity calculations refer to existing references in the literature.

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

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
