Abstract

The lower structure has a role to maintain the stability of the structure of the building and is the most vital thing in building planning. The substructure itself is one of the foundations. Foundation is defined as the lowest part of the building that functions to transmit the load of the building to the soil or rocks below it. The purpose of this research is to plan the pile foundation in the low-rise apartment and plan the required budget. Based on the soil investigation, it was found that the soil type was dominated by silty clay. The foundation is planned to use bored pile with a diameter of 0.7 m with a depth of 20 m on sample bore hole 02 and 15 m on sample bore hole 03. The ultimate axial bearing capacity calculation using the Meyerhof method is obtained at 492.162 tons in bore hole 02 and 677,195 tons in bore hole 03, with a permit axial capacity of 196.865 tons on bore hole 02 and 270,878 tons on bore hole 03. The calculation of single pile settlement using the Semi-Empirical Method is obtained at bore hole 02 of 0.025 m and on bore hole 03 of 0.021 m with an immediate settlement calculation at pile group using the Vesic Method is in the range of 2,946 – 5,140 m. The pile cap design obtained consists of three pile configurations, namely 2, 4 and 8 piles.

Abstract

Construction projects face time risks, such as delays causing cost overruns, and cost risks, including cash flow bottlenecks hindering funding. Effective cash flow management is critical to ensure project profitability and success, measured through both physical and financial aspects. This study compares the optimal profits of projects without a down payment and with a 20% down payment, under float utilization rates of 0%, 25%, 50%, 75%, and 100%. Using Microsoft Project 2021 and the Precedence Diagram Method (PDM), critical path and float durations were analyzed to assess financial feasibility with Net Present Value (NPV), Benefit-Cost Ratio (BCR), and Return on Investment (ROI). Results show the most optimal cash flow without a down payment occurs at 50% float utilization, yielding an NPV of IDR 2,121,722,719, a BCR of 1.0698, and an ROI of 6.98%. For a 20% down payment, optimal results occur at 25% float utilization, with an NPV of IDR 1,998,159,242, a BCR of 1.0568, and an ROI of 5.68%. These findings emphasize the importance of strategic cash flow planning to optimize financial performance in construction projects.

Abstract

Since the COVID-19 pandemic in March 2020, the economy of Semarang has grown. The demand for office space has increased due to business expansion, resulting in high land prices due to government restrictions on development. Renting office space has become an effective solution by utilizing space vertically and providing adequate facilities. In the construction of tall buildings, mature structural planning is necessary to ensure stability and compliance with the latest SNI standards. Structural analysis follows the requirements of SNI (2847-2019) for structural concrete and SNI (1726-2019) for earthquake resistance planning. The research method involves primary data such as building technical drawings, soil data, and earthquake data, which are then analyzed using ETABS V.18 software. The analysis results show a maximum story displacement of 68.838 mm in the X direction and 83.941 mm in the Y direction, with a permissible structural displacement of 90 mm. The maximum story drift ratio in the X and Y directions is 0.009 mm and 0.011 mm, respectively, with a permissible structural drift ratio of 0.0909 mm. The largest torsion irregularity in the X and Y directions is 1.0813 and 1.1781, respectively, which are both below the permissible torsion irregularity value of 1.4. It can be concluded that the building is categorized as safe as it does not exceed the limits of displacement and torsion.

Abstract

With increasing development in the construction sector, construction implementers are required to be faster and more efficient in completing project activities. The Permata River View housing development does not use BIM in its implementation. This research aims to carry out modeling with BIM software in 3D form and Quantity take-off. In this research, the Tekla Structures application will be used in the Permata River View housing complex. The modeling will start from the foundation, sloof, beams and columns along with the reinforcement. In this modeling, the material standards and concrete compressive strength are adjusted to SNI, the distribution of reinforcement in the Permata River View housing complex does not comply with the SRPKM and SRPMM stated in the SNI 2847:2019 regulations. However, the distribution of reinforcement is still in accordance with SNI. In this modeling we also get a comparison from Tekla Structures to RAB of 94.25% for concrete and 115.1% for reinforcement. The application of BIM using the Tekla Structures Application produces more accurate calculations and also makes work easier so it is faster, saves human resources and also and can be accounted for with objects that have been modeled in Tekla Structures

Abstract

This study focuses on the repair of substructure and the installation of carbon FRP to enhance the capacity and performance of a pier, with a case study at Pax Ocean Batam. A pier, which is infrastructure extending into the sea and often exposed to chloride-containing seawater, is prone to concrete corrosion that can shorten the structure’s lifespan. To ensure the safety and operational continuity of the pier, structural evaluation through field inspections, structural testing, analytical modeling, and repair recommendations is necessary. The study employs a quantitative research method, using primary data obtained from field surveys and secondary data from related documents. Non-Destructive Testing (NDT) using Ultrasonic Pulse Velocity (UPV) was conducted to assess the quality of the concrete and the extent of cracking. The findings indicate that the concrete quality is generally in the good to moderate range, though some areas require repair. Repairs were focused on areas with damage, such as delaminated concrete and cracking. To improve the structural capacity, reinforcement with Carbon Fiber Reinforced Polymer (CFRP) was applied. The repair recommendations include strengthening the damaged slabs, beams, and columns to ensure the safety and optimal performance of the pier.

Abstract

Rapid urbanization in Batam City has transformed its landscape, reducing water absorption areas due to the conversion of green spaces into residential and commercial zones. This has increased surface runoff, contributing to a higher risk of flooding. This study employs a quantitative method with a survey approach and descriptive quantitative analysis of land-use and drainage system data. Spatial analysis was conducted to identify land-use changes and their impact on drainage networks. Batam's rapid economic development has brought positive benefits but also significant negative environmental impacts, as construction activities often disregard land-carrying capacity. Flooding is closely linked to urban expansion, population growth, and land demand for residential and economic purposes, which increases by 0.9% annually. The study reveals that surface water volume rises yearly due to diminished groundwater absorption capacity. To address this issue, it is recommended that the Batam City government establish stricter regulations on land use to mitigate future flood risks.

Abstract

The Aria Apartment project is the construction of a modern apartment complex that requires a strong and safe pile foundation. To ensure the quality and strength of the piles, a PDA Test (Pile Driving Analyzer Test) is carried out. PDA Test is a non-destructive method used to measure the performance and integrity of piles by utilizing vibration waves produced during driving. In this project, the PDA Test was carried out to test the pile bearing capacity against dynamic loads, check the structural integrity of the pile, and ensure that the pile installation complies with the design specifications. This test provides data regarding ultimate compressive strength, energy transfer efficiency, and the possibility of defects or damage to the pile.The PDA Test results show that the piles used in the "The Aria Apartment" project have adequate strength and integrity to support the planned building structure. Thus, the PDA Test is an important part of ensuring the quality and safety of the foundation on this project, as well as providing additional confidence for stakeholders regarding the reliability of the construction.

Abstract

Mooring Dolphin is an important port infrastructure that often receives high dynamic loads and is at risk of damage due to ship collisions, as occurred in Tanjung Uban, where the Mooring Dolphin owned by PT Pertamina was damaged after a collision with a vessel from PT Soechi Lines. This study uses the Ultrasonic Pulse Velocity (UPV) method as part of a Non-Destructive Test (NDT) to evaluate the level of structural damage. UPV works by measuring the speed of ultrasonic waves through concrete to identify cracks, voids, or weak zones. Testing was conducted on the upper and lower structures of the Mooring Dolphin, with results showing cracks ranging in depth from 2 to 15 cm and widths of 0.2 to 1.5 mm, particularly in the areas directly affected. Most of the structure showed wave speeds above the safe threshold, indicating that the integrity of the concrete is relatively good; however, zones with low wave speeds were found that require repair. This study demonstrates that the UPV method is effective in providing detailed information about the location and extent of damage to support repair processes. Technical recommendations include epoxy injection in cracks and additional reinforcement in critical areas to enhance the structure's resistance to dynamic loads. The findings of this study are expected to serve as a reference for the evaluation and repair of port structures that experience similar damage.

Abstract

Mineral waste, particularly from synthetic fabrics, is challenging to manage due to its non-decomposable nature and inability to compost. This waste accumulates, posing environmental risks. As a solution, utilizing fabric waste in concrete mixtures has been proposed. This study aims to evaluate the compressive strength and stiffness of concrete with added fabric waste and identify the optimal percentage of waste as fiber reinforcement. The research employed experimental methods following the SNI-03-2834-2000 standard at the Structural Materials Laboratory, Muhammadiyah University of Parepare, conducted from February to March 2024. Results showed that on the 28th day, adding 5% table iron increased concrete compressive strength to 9.91 MPa, while increasing it to 10% reduced strength to 0.66 MPa. Adding 10% cotton fabric improved compressive strength by 2.23 MPa and flexural strength by 3.822 MPa. The findings suggest that fabric waste, combined with vibration and wire reinforcement, enhances concrete performance. The optimal results were observed with 5% boron material for compressive strength and 10% cotton material for flexural strength, demonstrating the potential of textile waste as an effective concrete mixture component. This study highlights the dual benefits of waste reduction and material enhancement, contributing to environmental sustainability and advancing concrete technology.
