Abstract

Construction projects on soft soils face significant technical and financial challenges due to low soil bearing capacity and high potential for settlement. These unique characteristics require effective integration of design and implementation to overcome high risks and improve structural stability. This study develops a Decision Support System (DSS) model based on Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) applied to the process of selecting foundations and construction methods for buildings on soft soils. This DSS enables a comprehensive assessment of various design alternatives and construction methods based on multi-aspect criteria, including stability, cost, time, material, and environmental conditions. Through data analysis and questionnaires involving construction experts, this DSS was tested on an infrastructure project in the tidal area of ​​South Kalimantan. The results show that this DSS model is effective in supporting the selection of foundations, such as piles and bored piles, which are adjusted to the building load and soil conditions. This DSS also provides implementation priorities that can minimize the risk of project costs and delays. In addition to improving efficiency and accuracy in decision making, this model offers an integrated approach that optimizes every stage of construction from planning to field execution. This DSS contributes to the development of better and more sustainable risk management methods in construction projects on soft soils. These findings are expected to be applied more widely in the construction industry, especially in efforts to manage the high risks associated with soft soil conditions and create more efficient and stable construction.

Abstract

To overcome the problem of flooding and tidal flooding in the city of Semarang, especially in the eastern part of Semarang, the Semarang-Demak Toll Road was built which is integrated with the sea wall. The sea wall is planned to prevent sea water from entering the land area, however, the sea wall will also block the direct flow of several rivers to the sea so that a fairly large coastal reservoir is needed. As in general, coastal reservoirs and retention ponds often experience sedimentation problems which have an impact on the economic value of the reservoir concerned, while in the planning of coastal reservoirs and retention ponds in general they are not equipped with sediment retaining structures. From this study, the results of the selection of the right type of sediment retaining structure to be applied in coastal reservoirs were obtained. The selection of the type of sediment retaining structure in this study used the AHP (Analytical Hierarchy Process) method, which is a decision support model that involves experts who have knowledge and experience in planning or implementing retention ponds or sedimentation in river estuaries. From the results of the global priority analysis above, the weight of each alternative sediment retaining structure is obtained, namely a fixed dam of 33.21%, a vertical movable dam with an upper opening of 31.35%, without a sediment retaining structure of 19.61%, a vertical movable dam with a lower opening of 15.84%. From the results of the AHP analysis above, the highest weight was obtained, which was then used as a decision maker to choose the type of building with the highest value, namely a sediment retaining structure in the form of a permanent dam.

Abstract

This study aims to analyze the influence of the quality of infrastructure facilities and human resources (HR) competence on the effectiveness of the building licensing process in Denpasar City. The change in regulations from Building Permits (IMB) to Building Approvals (PBG) under the Job Creation Law 2020 provides new challenges in implementing building permits, especially in areas with high levels of development, such as Denpasar City. This study uses a quantitative approach with the Partial Least Square-Structural Equation Modeling (PLS-SEM) method to test the contribution of infrastructure facilities and human resource competence to the effectiveness of licensing. The results show that the quality of infrastructure has a significant influence with an R-square value of 0.45 and a direct influence of 0.60, which means that improving the quality of infrastructure has a positive impact on the smooth licensing process. In addition, HR competence also has a significant influence on the effectiveness of licensing, with an R-square of 0.40 and a direct impact of 0.55. These two variables, when integrated, form an optimal service model that improves licensing efficiency and community satisfaction. These findings show that investment in infrastructure and human resource training focused on enhancing SIMBG's technical and operational skills is an important step to improve the quality of public services. This study provides recommendations to the local government of Denpasar City to increase investment in digital infrastructure, especially in the SIMBG licensing system, and carry out periodic training for employees involved in the licensing process. This recommendation is expected to support the implementation of PBG that is more effective, responsive, and to the needs of the community and permit applicants.

Abstract

A common problem faced by most reservoirs during their operational period is sedimentation. Sedimentation problems occur due to high levels of land erosion which is influenced by land use in the reservoir catchment area. Based on this, the aim of this research is to determine changes in land use in the reservoir catchment area, the amount of erosion and sedimentation caused by land use and the influence of erosion on the estimated service life of the reservoir. The research location is in the water catchment area of ​​the Gerokgak Reservoir, Buleleng Regency, Bali Province. The data needed in this research includes land use maps and topography of the reservoir catchment area, planning data for the Gerokgak Dam and soil types. The methods used in this research are the Universal Soil Loss Equation (USLE) method to predict the amount of land erosion and the Sediment Delivery Ratio to determine the percentage of sediment entering the reservoir as well as the dead storage comparison method with the amount of sediment to determine the estimated service life of the reservoir. Based on the land use map, the land use condition of the Gerokgak Reservoir water catchment area in 2023 is 95.5% forest and 4.5% rice fields. The average rate of land erosion from 2018 to 2023 is 27.427 tons/ha/year with potential sedimentation of 9,698.563 tons/year. Based on the amount of sediment, it can be analyzed that the service life of the Gerokgak Reservoir is around 5.279 years.

Abstract

Aerodynamic phenomena poses risks for long-span cable-stayed bridge structures, nevertheless, the prevention method is often neglected on older bridges. The effort to reduce the risk and increase the aerodynamic performance of cable-stayed bridges mostly focuses on design and construction stages. This study attempts to improve aerodynamic performance by mitigating the aeroelastic heaving response of an existing bridge structure chosen as the subject, Suramadu Bridge. The approach is made by exploring different options applicable to already built bridges, such as the addition of fairings with varying shapes to modify the shape model of the bridge deck while maintaining the value of vertical and torsional stiffness. The study finds that there is relatively no increase in the lowest margin of critical vortex velocity of the bridge deck with fairing addition compared to the original bridge deck. The amplitude of oscillation caused by aerodynamic lift force is also fairly low since critical vortex velocity occurs in the range of 9.35-9.38 m/s. Upon increasing wind velocity up to the design wind speed of 37.8 m/s, there are significant differences in lift force and amplitude of oscillations. The shape model with the steepest fairing shows a significant decrease in amplitude, up to 35.6% lower than the original bridge deck, indicating a better aerodynamic stability. Meanwhile, the other two shape models show identical and higher amplitude compared to the original bridge deck.

Abstract

Field load testing using static loading is widely applied as a non-destructive testing (NDT) method for bridge assessment due to its practicality and ability to provide immediate, on-site results. This approach is suitable for both new and old bridges, requiring strength evaluation to understand the behavior and fundamental characteristics of the bridge. In this paper, 40.8 span PCU Girder Bridge was tested with a static loading test to obtain key performance and response indicators, such as the maximum deflection of the bridge under static load. The research findings showed that the bridge’s maximum deflection was -13.8 mm from the field load test, indicating the bridge structure is below the design limit of -35.7 mm, confirming its capacity to support a 192-ton load. The experimental results indicate that the bridge remains within the elastic range when subjected to the planned test loads. This suggests that the bridge has sufficient load-bearing capacity. Additionally, these findings reflect the current condition of the structure, which can serve as a foundation for ongoing structural health monitoring and future maintenance of the bridge.

Abstract

Puncak area, located in Bogor, is known as one of the main tourist destinations as well as an important conservation area for the ecosystem in the Jabodetabek area. With its crucial ecological role as a water catchment and flood control area, this area faces rapid development pressures, especially for the tourism and housing sectors. This study explores changes in land use and spatial planning in Puncak area and their impacts on environmental quality and the socio-economic well-being of local residents. This article results show that the conversion of green land into built-up areas, such as housing and tourism facilities, has reduced environmental quality, increased disaster risks, and changed the socio-economic structure of the community. In addition, inconsistencies in spatial planning and weak supervision of regulatory implementation have further exacerbated this situation. Therefore, a more comprehensive and sustainable spatial management approach is needed to maintain the balance between development and environmental conservation in this area.

Abstract

Sustainable mining requires the implementation of Good Mining Practice (GMP) principles to minimize negative environmental impacts, particularly on tailing disposal sites. One important aspect of GMP is post-mining land rehabilitation, especially on tailing sites that have the potential to cause ecosystem damage. Tailing-affected lands require restoration involving plants capable of adapting to extreme environmental conditions. This study aims to apply GMP by utilizing angiosperm vegetation for land rehabilitation at the Research Center Mile 21, PT. Freeport Indonesia. Tailing-contaminated lands need recovery through plants that can thrive in harsh conditions. Angiosperm plants were selected for their ability to improve soil structure, reduce erosion, and enhance soil fertility. This research evaluates the effectiveness of angiosperm vegetation in accelerating soil recovery and supporting ecosystem sustainability. The findings are expected to provide valuable information and recommendations for more effective tailing site rehabilitation management and serve as a reference for environmentally friendly mining practices in the future.
