Abstract

Groundwater recharge is a crucial factor in determining the permissible groundwater extraction within a watershed. In the Cikapundung watershed, the contribution of groundwater to raw water supply has been continuously declining, prompting a shift from groundwater to surface water usage. This study aims to quantify the groundwater recharge volume and recharge coefficient for each geological formation within the Cikapundung-Gandok watershed, covering an area of 90.4 km², and to compare the results with previous studies. The analysis estimates recharge volumes based on rainfall data from 8 stations around the Cikapundung-Gandok watershed from 2010 to 2019, geological formation data, and alternative recharge coefficients. The difference in recharge volume from previous studies is 393,348 m³/year or 1%. Two formations, Qvu and Qyu, which were not identified in earlier studies, supplement the existing geological dataset. The selected recharge volume for the Cikapundung-Gandok watershed is 33,232,004 m³/year or 1.05 m³/s, with the lowest contribution from the Lava formation (Qyl) at 1,364,504 m³/year or 0.04 m³/s and the highest from the Old Volcanic Product (Qvu) at 14,072,243 m³/year or 0.45 m³/s. The tentative recharge coefficients for each rock formation are as follows: Colluvium (Qc) 30%; Unweathered Old Volcanic Product (Qvu) 20%; Sand Tuff (Qyd) 10%; Lava (Qyl) 25%; Pumiceous Tuff (Qyt) 20%; and Young Volcanic Product (Qyu) 20%. The groundwater recharge data obtained can be used to set groundwater extraction limits and to plan for groundwater management using a conservative approach to ensure long-term sustainability.Keywords: groundwater recharge, recharge coefficient, geological formation, groundwater exploitation, Cikapundung-Gandok Watershed

Abstract

The Phase I development project of the Onan Runggu Port in Samosir Regency, North Sumatra, is a strategic government initiative to improve connectivity and water transportation access on Lake Toba. This port is expected to stimulate local economic growth and the development of the tourism sector. However, the project faces a number of technical risks that can disrupt its smooth implementation and timely completion. Based on the analysis, one risk was found to be on a medium scale, eighteen risks on a high scale, and one risk on an extreme scale. Risk control can be carried out through preventive and corrective measures, such as weather monitoring, work schedule adjustments, technical drawing inspections, and the implementation of a strict quality control system. In addition, preparing backup materials and equipment, as well as worker training, is very important. These risk controls aim to reduce the impact on the time performance of the Phase I Onan Runggu Port development project in North Sumatra.

Abstract

Basement structure work is a crucial part of constructing multi-story buildings, especially in dense urban areas with limited workspace or heavy equipment maneuverability. This study aims to analyze the comparison between two basement construction methods, namely the Cut-and-Cover method and the Top-Down construction method, using a case study on the Wahid Hasyim Apartment building project in Medan, North Sumatra. The analysis is based on two main parameters: execution duration and construction cost. The research findings indicate that the Cut-and-Cover method requires an execution time of 215 days with a total cost of Rp. 59,297,411,788.65. Meanwhile, the Top-Down method only requires an execution time of 164 days with a total cost of Rp. 48,012,728,671.13. Based on these results, the implementation of the Top-Down construction method is proven to be superior, with a time effectiveness of 23.72% and a cost efficiency of 19.03% compared to the Cut-and-Cover method. This is because with the Top-Down method, several work items can be performed concurrently.

Abstract

The construction of high-rise buildings is influenced by land limitations and advances in construction technology. However, these structures present more complex technical risks, particularly in earthquake-prone regions such as Indonesia. Earthquake-resistant structural design serves as a preventive approach to minimize potential casualties and post-disaster losses, rather than to create completely earthquake-proof buildings. Concrete and steel are commonly used structural materials in high-rise buildings due to their high strength, but their selection also considers various other parameters beyond strength alone. This study analyzes the comparative seismic performance of high-rise building models using steel and reinforced concrete materials. The analysis focuses on base shear force, inter-story drift response, and the impact of P-Delta effects using the response spectrum method in ETABS v.21 software. The results show that the total base shear force (Vtotal) in the Reinforced Concrete Structure (RCS) model is 28,979.31 kN, while in the Steel Structure (SS) model it is 8,133.61 kN. The higher value in the RCS model is due to its greater structural weight and shorter structural period. Both models meet the allowable inter-story drift limits, with the RCS model showing smaller displacements: 50.001 mm (X direction, 10th floor) and 41.058 mm (Y direction, 9th floor), compared to the SS model’s 50.930 mm (X direction, 8th floor) and 40.700 mm (Y direction, 7th floor). Furthermore, the P-Delta effect in both models remains within safe limits; however, the RCS model exhibits smaller maximum values of 0.0220 and 0.0185 compared to the SS model’s 0.0649 and 0.0530, indicating better seismic stability in the reinforced concrete structure.

Abstract

Castellated steel is a steel beam that has a hexagonal hollow web element. One of the cases that often occurs in castellated steel structures is buckling. This study takes a case study of ramp door construction made of castellated steel. The ramp door construction experienced buckling damage after a load test. Analysis was carried out on four ramp door models with loading resembling the actual conditions of the bridge according to SNI 1725-2016. The first modeling uses a 900x200x11x17 castellated main beam without the addition of stiffeners. The second modeling with the addition of stiffeners at each distance between castellated holes. The third modeling closes all holes without the addition of stiffeners. The fourth modeling closes all holes with the addition of stiffeners at each distance between castellated holes. The analysis was carried out using the finite element method. This study aims to determine the effect of stiffeners and castellated hole covers on deformation values, equivalent stress and buckling eigenvalues. From the analysis of the effect of stiffener (second model) for the deflection value decreased by 0.62%, the stress value increased by 4.04%, the buckling eigenvalue increased by 144.94%. The effect of castellated cover (third model) for the deflection value decreased by 8.69%, the stress value decreased by 19.71%, the buckling eigenvalue increased by 12.75%. The effect of stiffener and castellated cover (fourth model) for the deflection value decreased by 11.18%, the stress value decreased by 20.15%, the buckling eigenvalue increased by 153.98%.

Abstract

The implementation of VE in the construction sector is an approach carried out systematically by a team from many disciplines that focuses on value and function. The implementation of VE in construction projects has the potential for significant savings from the project budget. In the construction world, project owners are often faced with various constraints such as budget constraints, increasing material costs, and the need for time efficiency. VE offers a solution to overcome these constraints with a functional analysis-based approach that aims to increase value by reducing unnecessary costs without reducing the quality of the final product. The implementation of VE carried out in construction projects, the techniques and alternatives used vary, this is due to the approach used, cultural conditions, and different procurement systems. The purpose of this study is to identify VE practices in Indonesia, examine the success factors in these practices, knowledge and experience of VE, and the constraints often faced in VE practices. The research method was carried out by distributing questionnaires to respondents who had knowledge of VE. The data obtained from the questionnaire were analyzed using descriptive analysis. The results of the analysis show that the implementation of VE in Indonesia is carried out on projects that are being proposed and on projects that are underway, the knowledge and experience of construction actors are the main success factors, construction actors have sufficient knowledge about VE, and the lack of knowledge about VE is the main obstacle in the implementation of VE in Indonesia.

Abstract

The ongoing construction of the project requires a fairly large allocation of funds, and it is necessary to reconsider whether the design used is optimal. This can be done by reviewing the project planning design so that it is possible to make cost savings by identifying and reducing unnecessary costs without reducing the level of quality, reliability and function of the project itself. Carrying out value engineering techniques, namely carrying out cost analyzes by comparing the costs per item with the details of each job from the contractor's offer to find the cheapest price up to the negotiation stage for cost savings and efficiency. The AHP (Analytic Hierarchy Process) method can be used as a solution to problems in finding decisions, and for assessment using a Likert scale questionnaire. Value engineering in the planning review by taking a case study of an ongoing project in the Pengambengan area of ​​Bali, namely the integrated fishing port project. There are 3 alternatives compared to the planning budget, namely breakdown analysis techniques (Work Breakdown Structure), cost modeling techniques (Cost modeling techniques), and Delphi techniques (Delphi Teqhnique). In value engineering, you can see the price comparison for each work item for planning reviews. The results for the final review based on value engineering RAB planning estimate Rp. 1,626,877,637,500. The stages in the AHP method analysis are determining the objective of the analysis, namely value engineering in selecting contractors, determining the analysis criteria: Cost Budget Plan, Detailed Drawings, Technical Specifications, and Implementation Time, as well as determining alternative options

Abstract

Engineering, Procurement, and Construction (EPC) projects face complex challenges such as multidisciplinary coordination, tight schedules, material procurement risks, and design change dynamics, which require the crucial role of Construction Management Consultants (CMCs) in ensuring the achievement of time, cost, and quality targets. This study analyzes the influence of expert competence, quality management, and communication on CMC performance in the coal processing facility construction project in Tanjung Enim, South Sumatra. The study employs a quantitative approach using research instruments developed based on indicators of expert competence, quality management, and communication. Instrument validation was conducted using item analysis with Pearson's product-moment correlation coefficient, while reliability was measured using Cronbach's Alpha coefficient. Data were analyzed using partial correlation and multiple regression techniques. The results of the study indicate: (1) Expert competence has a significant positive effect on KMK performance (ry1 = 0.377 > 0) with the regression equation Ŷ = 19.843 + 0.144 X1; (2) Quality management has a significant effect (ry2 = 0.543 > 0) with the equation Ŷ = 19.040 + 0.174 X2; (3) Communication makes an important contribution (ry3 = 0.471 > 0) with the equation Ŷ = 19.590 + 0.152 X3. Multiple regression analysis shows that the three variables together explain 82% of the variance in performance (ry123 = 0.9272 > 0) with the equation Ŷ = 3.9547 + 0.200 × X1 + 0.1995 × X2 + 0.2237 × X3. These findings confirm that the performance of construction management consultants on EPC projects is significantly influenced by expert competence, quality management, and communication. The study recommends the need for standardization of competencies, implementation of an integrated quality management system, and development of an effective communication model to improve the performance of CMC on similar projects.
