Abstract

Taman Ratu Housing Area which is included in the drainage area of the Taman Ratu connecting channel is almost always flooded with a height variation of 30-60 cm at the peak of the rainy season. One solution of the flood control system according to the principle of sustainable drainage is the utilization of storage ponds. The availability of land, which is dominated by residential areas, motivates the placement of below ground pools with 2 different models, known as concrete pond and modulars. The placement of below ground ponds is also intended to fulfill public facilities into green open space areas. Therefore, this study was conducted to determine the comparison of cost budget plans related to the dimensions of the planned pond. The method that will be used through three stages of research includes hydrological analysis to calculate planned rainfall and planned runoff discharge, followed by hydraulic analysis for the design on the total land area of the development plan of 2015.88 m2, the maximum storage volume obtained with dimensions of 45×45×1.5 m is 421.84 m3 for a 5-year rain return period. The preparation of work unit prices refers to the Minister of PUPR Regulation No.8 of 2023 so that a budget value of Rp 6,256,025,595.86 for concrete pond and Rp 10,518,367,732.62 for modular pond is obtained.

Abstract

Recent studies on nanomaterial concrete in Indonesia have demonstrated improvements in mechanical properties, particularly in the context of fatigue life for concrete road pavements. While traditional designs focus primarily on traffic axle loads, curling stress from temperature differentials also plays a significant role. Previous research using 3D finite element analysis (FEA) software, such as EverFE2.26, showed that the tensile and curling stresses matched those calculated by established methods like Westergaard and Bradbury. This research uses a mechanistic approach and 3D finite element analysis (FEA) software for simulations. A literature review gathered data on the mechanical properties of nanomaterial concrete. After inputting all required parameters, EverFE2.26 performed a stress analysis, allowing for the calculation of concrete pavement fatigue life. The simulation showed that temperature differential greatly impacts the fatigue life of concrete pavements in tropical environments like Indonesia. Nevertheless, nanomaterial concrete could be a promising option to reduce those impacts if its strength can be further improved
