Abstract

The intersection of Jalan H. Rais is where 3 (three) roads meet, namely Jalan H. Jamat Gang Rais, Jalan Puspitek Segment 1, and Jalan Puspitek Segment 2. This intersection often experiences long queues due to inadequate intersection capacity so that it cannot accommodate the volume of vehicles during morning and evening rush hours. The research method used was a direct survey method at the research location to collect traffic data at the H. Rais intersection and the surrounding roads. The research results found that the average length of the queue before handling during peak hours on weekdays was 168.52 m and delays were 35,471 with an intersection service level (LOS) D, while the average length of the queue before handling during peak hours on holidays was 119 .82 m and a delay of 33.52 with a level of service (LOS) D. H. Rais intersection performance for the next 5 years, before handling becomes worse with the result that the average queue length during weekday peak hours is 219, 64 m and a delay of 49,137 with an intersection service level (LOS) E, while the average queue length during holiday peak hours is 218.28 m and a delay of 43,635 with an intersection service level (LOS) E. Handling that needs to be done at the intersection H. Rais road in short-term scenario 1 is by providing road equipment facilities and assignment of traffic officers, and in short-term scenario 2 by widening the bend radius to a minimum of 7.8 m and widening the H. Jamat Gang Rais road to 6 m, while The treatment carried out at the H. Rais intersection in the long term is to change the Puspitek road type to 4/2-T with a width of 6 m per direction.

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 aviation industry increasingly relies on composite materials to optimize performance and reduce weight in high-speed aircraft structures. These materials offer superior strength-to-weight ratios, corrosion resistance, and design flexibility. Understanding the mechanical properties of composite materials is essential for enhancing the safety and efficiency of high-speed aircraft. This research aims to analyze the strength characteristics of composite materials used in high-speed aircraft structures. The study focuses on evaluating the mechanical properties and performance under various loading conditions to determine their suitability for aviation applications. An experimental approach was employed, involving the fabrication of composite samples using different matrix and fiber combinations. Tensile, compressive, and flexural tests were conducted to assess mechanical properties. Data were collected and analyzed to evaluate the performance of each composite configuration under simulated operational conditions. The findings indicated that hybrid composite materials exhibited the highest strength and stiffness, outperforming traditional materials. The tensile strength of the best-performing composite reached up to 600 MPa, while flexural tests showed significant resistance to deformation. These results highlight the potential of advanced composites to enhance the structural integrity of high-speed aircraft. The research underscores the importance of selecting appropriate composite materials for high-speed aircraft applications.

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.
