Abstract

This study presents a comparative analysis of the technical effectiveness and cost efficiency of three ground reinforcement methods—geogrids, soil nailing, and gabion retaining walls—for slope stabilization in highway construction projects. Numerical modeling using geotechnical software was conducted to evaluate the performance of each method based on the increase in the factor of safety (FS) and the degree of slope deformation. The results indicate that soil nailing is the most technically effective method, providing the highest FS increase (up to 1.68) and the best control over deformation. However, it also incurs the highest implementation cost. In contrast, geogrids proved to be the most cost-efficient solution, although with a more moderate FS increase. Meanwhile, gabion retaining walls offer a good compromise between performance and cost. The study concludes that the optimal choice of a ground reinforcement method must be based on a multi-criteria analysis that considers specific geotechnical conditions, safety priorities, and budget availability. The findings of this research are expected to serve as a practical guide for engineers in designing safe, efficient, and sustainable slope stabilization solutions.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan pengenalan dunia kerja bagi mahasiswa Program Studi Teknik Sipil Universitas Widya Kartika, dengan fokus pada persiapan lulusan yang siap bersaing di industri konstruksi. Kegiatan dilakukan secara online melalui Google Meet, dan diikuti oleh mahasiswa Universitas Widya Kartika. Materi disampaikan oleh seorang narasumber yang merupakan praktisi industri konstruksi, yang memberikan wawasan terkait perkembangan teknologi konstruksi terbaru dan green building, serta pentingnya pengembangan soft skills. Hasil evaluasi menunjukkan bahwa kegiatan ini sangat bermanfaat dalam meningkatkan pemahaman mahasiswa mengenai  tantangan dunia kerja, serta memberikan saran praktis untuk mempersiapkan diri memasuki industri konstruksi. Kesimpulannya, kegiatan ini berhasil menjembatani kesenjangan antara teori yang dipelajari di kampus dengan praktik di lapangan, dan memberikan arahan untuk persiapan karier yang lebih baik.

Abstract

The carpentry training program in Mudik Village aims to improve the technical and entrepreneurial skills of the community as part of local economic empowerment efforts. The three-day training program utilizes a combination of theory and practice. The first day focused on theoretical material, including an introduction to wood types, equipment usage, measurement techniques, occupational safety principles, and entrepreneurial fundamentals. The second and third days focused on hands-on practice in making simple products, such as bookshelves, covering the measuring, cutting, assembly, and finishing processes. Evaluation results showed significant skill improvements across all aspects, with the greatest improvement in the ability to use modern tools (+64%). Furthermore, participants demonstrated increased awareness of occupational safety and understanding of product marketing strategies. This training demonstrated that the three-day, integrative approach can improve skills while motivating the community to develop carpentry businesses. Future recommendations include further training, business mentoring, and the formation of village business groups to support the program's sustainability.

Abstract

Traffic congestion has become a major transportation challenge affecting mobility, economic activities, and regional accessibility, particularly along national roads that serve as primary transportation corridors. This study aims to analyze the effect of traffic volume on traffic congestion levels along national roads in Nias Regency, Indonesia. A quantitative descriptive approach combined with correlational analysis was employed to examine the relationship between traffic volume and roadway operational performance. Primary data were collected through manual traffic surveys conducted during morning, midday, and evening observation periods over seven consecutive days. Vehicle counts were converted into Passenger Car Units (PCU) based on the Indonesian Highway Capacity Guidelines (PKJI 2023). Traffic congestion levels were evaluated using road capacity, Volume-to-Capacity (V/C) ratio, average travel speed, and Level of Service (LOS). The influence of traffic volume on congestion was analyzed using simple linear regression. The results indicated an average traffic volume of 1,535.5 PCU/hour, an estimated road capacity of 1,850 PCU/hour, and a V/C ratio of 0.83, corresponding to Level of Service (LOS) D, which represents unstable traffic flow approaching roadway capacity. Regression analysis produced a correlation coefficient (R = 0.914) and a coefficient of determination (R² = 0.835), indicating that approximately 83.5% of the variation in traffic congestion levels could be explained by traffic volume. The statistical test confirmed that traffic volume has a significant positive effect on traffic congestion along national roads in Nias Regency (p < 0.001). The study concludes that increasing traffic demand substantially reduces roadway operational performance and recommends integrated congestion management strategies, including traffic control optimization, roadside activity regulation, parking management, and long-term infrastructure improvements to support sustainable regional transportation.

Abstract

High-rise buildings in coastal environments are exposed to complex geotechnical and environmental conditions that significantly affect foundation performance. This study evaluates the behavior of high-rise building foundations under variable soil and load conditions using field investigation, laboratory testing, and numerical modeling. Soil stratigraphy, groundwater fluctuations, and load variability were analyzed to assess settlement, differential tilting, and stress distribution. Results indicate that pile foundations outperform mat and combined mat-pile foundations in controlling differential settlement and maintaining structural serviceability. Groundwater level changes and load variations notably influence foundation performance, emphasizing the need for site-specific, performance-based design. The integrated methodology provides insights for resilient foundation design strategies in challenging coastal environments.
