Abstract

The construction of access roads to Kenyamukan Port in Sangatta, East Kutai, faced a major challenge due to soft saturated soils with low bearing capacity and high settlement potential. To address this issue, a soil improvement system was implemented using a combination of Prefabricated Vertical Drain (PVD) and vacuum preloading methods. PVD functions to accelerate pore water discharge both vertically and horizontally, while vacuum preloading applies negative pressure to enhance consolidation without the need for heavy surcharge loads. This internship was conducted over ±2 months, focusing on the installation stages of PVD, perforated horizontal drains (PHD), geomembranes, and vacuum systems. Based on field observations and CPTu test data, this combined method significantly accelerated soil consolidation, increased effective stress, and reduced the consolidation period from over a year to approximately 90–120 days. The method is considered effective, efficient, and suitable for infrastructure projects on soft ground, especially in coastal areas. This practical experience also provided the student with hands-on knowledge of construction execution, technical skills, and real-world problem-solving in geotechnical engineering.

Abstract

Around 15,352 families (42.66 percent) in Samosir Regency still have access to clean water, which is still a rather low percentage compared to the remaining 20,638 families (57.34 percent) who do not. The local government is concerned with this situation in order to create the BUMD PDAM Samosir Regency. This research was done to see if it would be possible to start a local water firm in Samosir Regency. In order to determine whether there is a potential water source that is adequate, sustainable, and manageable economically and profitably in the context of public services, as well as whether the establishment of PDAM Samosir Regency is worth reviewing, interviews and questionnaires were distributed to the community, SPAM owners, and State Civil Servants. In addition to socioeconomic factors, there are financial factors, market factors, legal factors, managerial factors, organizational factors, and technical factors. Legal, social and economic, technical, and notably from economic considerations with IRR = 72.32> I = 12 percent / year, PP = 3.34, and BCR = 6.27, BUMD PDAM Samosir Regency is viable to be founded

Abstract

The construction of a multi-story parking building in densely populated areas such as Plaza 6 Pondok Indah is a response to limited land availability and the increasing demand for parking facilities. This project employs modern construction methods, such as minipile foundations and precast structural systems, to accelerate project timelines and maintain on-site efficiency. This study aims to directly examine the implementation process and structural systems used on-site, as well as evaluate their effectiveness in terms of technical performance and construction time. Data were collected through direct observation at the project site, technical documentation, and informal discussions with project personnel. Emphasis was placed on the stages of foundation work, substructure components such as pile caps and tie beams, and the installation of precast components on each floor. Additionally, the installation of steel structures was an essential aspect of this study. Observations revealed that the use of precast floor slabs significantly reduced construction time by minimizing the need for formwork and scaffolding. The steel frame system provided advantages in installation flexibility and faster on-site mobilization. The selection of minipiles as the foundation type was also appropriate for the limited land space and moderate soil bearing capacity. Overall, the construction methods used in this project offered substantial benefits in terms of time and on-site efficiency. This study may serve as an initial reference for similar projects, particularly in utilizing a combination of steel structures, precast elements, and deep foundations.

Abstract

Due to the time, the steel truss had been used in several roof application. Several analysis structure methods codes had been developed and adopted for steel building constructions design and analysis. Recently, some finite element analysis also had completed the structure analysis. This research had modelled and analyzed the howie type of roof steel truss structure. The direct stiffness method had been compared to the finite element method (FEM) that was utilized by SAP2000. The stress analysis had been evaluated by performing 3D solid tension and compression member by utilizing Abaqus. The National Standard of Indonesia for steel construction (SNI 1729 2020) that was also verified by AISC/ANSI 360 2022 had been considered in this research. The results showed similarity between Direct Stiffness Method and FEM about 1% - 2%. The maximum tension stress on bottom chord had been verified by 3D solid respectively 175 MPa (ASD) and 213 MPa (LRFD) for yielding criteria. For fracture criteria the stress was recorded consecutively 140 MPa (ASD) and 260 MPa (LRFD). The compression member had been recorded correspondently 267 MPa (ASD) and 270 MPa (LRFD). The stress number that was occurred on the top chord had satisfied the design requirements accorded to AISC/ANSI 360-2022. However, in the case of compression member should be designed in double cross section for preventing the buckling failure.

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

Soil compaction plays a crucial role in determining the stability of structures, particularly in earthquake-prone regions. Inadequate compaction can lead to soil liquefaction and settlement, increasing the risk of structural failure during seismic events. Understanding the impact of different soil compaction methods is essential for enhancing building resilience. This study aims to evaluate the influence of various soil compaction techniques on the stability of buildings in earthquake-prone areas. It seeks to identify the most effective methods that can improve soil properties and overall structural integrity. A comparative analysis was conducted using laboratory experiments and field tests. Different compaction methods, including static, dynamic, and vibratory compaction, were applied to soil samples. The study measured parameters such as soil density, moisture content, and shear strength to assess the effects of each method on soil stability. The findings reveal that dynamic compaction significantly improves soil density and shear strength compared to static and vibratory methods. Structures built on dynamically compacted soil exhibited greater resilience to seismic forces, demonstrating lower risks of liquefaction and settlement during earthquakes. The research concludes that the choice of soil compaction method is vital for ensuring the stability of buildings in earthquake-prone regions. Dynamic compaction emerges as the most effective technique, providing enhanced soil properties that contribute to structural resilience. Future studies should explore the long-term effects of compaction methods and their implications for building codes and practices in seismic areas.
