Abstract

Slope stability is a critical aspect of road construction projects, particularly in areas with hilly topography and complex soil conditions. Slope failure can lead to serious consequences, including disruption of road functionality, economic losses, and safety risks. This study aims to analyze slope stability in a road construction project using a numerical method based on the Finite Element Method. The analysis was carried out using the strength reduction method to determine the factor of safety and to identify deformation patterns and slope failure mechanisms. The data used include results of soil investigations, soil mechanical parameters, slope geometry, and groundwater conditions. The analysis results indicate that the unreinforced slope is in a critical condition, with a factor of safety below the recommended value. The application of reinforcement systems, particularly soil nailing combined with drainage systems, significantly increases the factor of safety and reduces slope deformation. This study concludes that numerical methods provide a more comprehensive and realistic approach to slope stability analysis and are highly recommended for the design and evaluation of slopes in road construction projects with complex geotechnical conditions.

Abstract

This study aims to analyze the utilization of local labor in construction projects in the Nias region and to identify the factors influencing their level of involvement. The research employs a descriptive quantitative approach, with data collected through questionnaires, interviews, and field observations. The sample was selected using a purposive sampling technique, involving construction workers, contractors, and project supervisors. Data analysis was conducted using descriptive statistics and factor analysis to determine the dominant factors affecting the use of local labor. The results indicate that the level of local labor involvement falls into a moderate category, accounting for approximately 60–70% of the total project workforce. The primary factor influencing the use of local labor is workforce competence, followed by contractor policies, education and training levels, as well as geographical and socio-cultural conditions. The use of local labor has a positive impact on increasing community income and employment opportunities; however, challenges remain in terms of work quality due to limited skills. This study concludes that optimizing the use of local labor requires improving competencies through training and certification, as well as strengthening policies that support local workforce empowerment. Synergy between the government, contractors, and the community is essential to achieving inclusive and sustainable construction development in the Nias region.
