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

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

Soil bearing capacity is a critical parameter in geotechnical engineering that determines the safety, stability, and performance of foundation systems. Accurate evaluation of bearing capacity is essential for selecting appropriate foundation types and preventing excessive settlement or structural failure. This study aims to evaluate the soil bearing capacity in Gunungsitoli City, Indonesia, based on Cone Penetration Test (CPT) results. A quantitative descriptive research approach was employed using in-situ CPT data collected from six representative investigation points. The analysis involved the interpretation of cone tip resistance (qc), sleeve friction (fs), friction ratio (Rf), soil stratification, and estimation of allowable bearing capacity through established empirical correlations. The results indicate that cone resistance generally increases with depth, reflecting a transition from soft clay and silty sand near the ground surface to dense sandy deposits at greater depths. The estimated allowable bearing capacity ranges from 320 kPa to 500 kPa, depending on local subsurface conditions. These values suggest that isolated footings are suitable for light to medium-rise structures, whereas raft or pile foundations are recommended for heavier infrastructure. Spatial variations in bearing capacity demonstrate the influence of local geological conditions, emphasizing the necessity of conducting site-specific geotechnical investigations before construction. Overall, the study confirms that the Cone Penetration Test provides a reliable, efficient, and economical method for evaluating soil bearing capacity and supports safer and more cost-effective foundation design for future infrastructure development in Gunungsitoli City.

Abstract

This study aims to analyze the soil conditions at the construction site of the BNKP Hosiana Church by conducting cone penetration tests (CPT) as a basis for designing a safe and efficient foundation system. The CPT was performed to obtain cone resistance (qc), sleeve friction (fs), and friction ratio (Rf) across various soil depths. The results indicate the presence of three main soil layers: a soft clay layer at depths of 0–2 meters with low bearing capacity, a silt or stiff clay layer at 2–6 meters with moderate bearing capacity, and a dense sand or hard layer below 6 meters characterized by high bearing capacity. Analysis based on the Robertson approach suggests that shallow foundations are not recommended due to the weak surface soil conditions. Deep foundations, such as driven piles or bored piles, are considered the most suitable option to reach the competent hard layer capable of supporting the structural load effectively. Therefore, the cone penetration test proves to be an essential tool for strengthening the planning of the BNKP Hosiana Church building project, particularly in ensuring the long-term safety and structural stability of the facility.

Abstract

This community service activity aimed to implement civil engineering expertise through the preparation of a building floor plan for BNKP Hosiana Church in Gunungsitoli City as a technical document to support the planning and development of worship facilities. The partner's main problem was the absence of a systematically documented floor plan, which hindered renovation planning, building development, and the preparation of technical construction documents. The activity employed a participatory approach consisting of coordination with the partner, field surveys, building measurements, data processing, floor plan preparation using AutoCAD software, validation with the church management, and submission of the final technical document. The results demonstrated that an accurate floor plan reflecting the existing building conditions was successfully produced and validated by the church administrators. The document serves as a reference for future renovation planning, building expansion, construction documentation, and systematic building asset management. In addition to producing a technical drawing, the activity improved the partner's understanding of the importance of technical planning documents in supporting effective, efficient, and sustainable building development. This community service demonstrates that the application of civil engineering knowledge can provide practical solutions to community needs through the provision of high-quality technical planning documents.

Abstract

Landslides are one of the major hazards in areas with hilly topography and high rainfall, such as Nias Island. Landslide risk is influenced not only by physical environmental factors but also by community perceptions of potential hazards. This study aims to analyze community perceptions of landslide risk in Nias and identify the factors that influence these perceptions. The research employs a quantitative approach with data collection techniques through questionnaires and interviews involving 120 respondents selected randomly from landslide-prone areas. Data analysis was conducted using descriptive and inferential statistics to determine perception levels and relationships between variables. The results indicate that community perception is at a moderate level, with education, experience, and access to information significantly influencing perception levels. Additionally, local wisdom plays an important role in supporting disaster mitigation efforts. Therefore, it is necessary to enhance education, socialization, and community involvement in community-based mitigation programs to improve preparedness for landslide risks in Nias.
