Abstract

Earthquakes that often occur in Indonesia are tectonic earthquakes. Indonesia is one of the countries in the earthquake area. Thus, the construction of structures built in earthquake-prone areas must meet applicable national standards and the structures can still function and be safe from earthquakes affected by the earthquake. Reinforced concrete shear walls are one of the structural elements that effectively resist earthquake forces. The application of reinforced concrete shear walls can effectively reduce the displacement and shear forces of the structure floor. This study aims to determine the effect of shear wall position on symmetrical high-rise buildings due to earthquake loads. In this research, the building that is analyzed is earthquake by considering two types of structural systems. Namely the frame system and the dual system. The first model is an open frame structure system, and the other three models are a double type structure system. The dual system with shear walls in the core and placed in the center of the building showed a significant reduction of more than 85% of lateral displacement at the top of the structure

Abstract

The seismic performance of reinforced concrete (RC) shophouse buildings is strongly influenced by local soil conditions, which affect the amplification of ground motion and the dynamic response of structures during earthquakes. This study aims to analyze the effect of soil classification on displacement and inter-story drift in a reinforced concrete shophouse building subjected to seismic loading. A quantitative research approach was employed using Response Spectrum Analysis (RSA) in accordance with the provisions of SNI 1726:2019. The structural model was analyzed under three different soil classifications, namely Site Class SC (very dense soil), Site Class SD (medium soil), and Site Class SE (soft soil), while maintaining identical structural geometry, material properties, and loading conditions. The results indicate that soil classification significantly affects the seismic response of the building. The maximum roof displacement increased from 42.8 mm for Site Class SC to 76.9 mm for Site Class SE, representing an increase of 79.67%. Similarly, the maximum inter-story drift ratio increased from 0.72% to 1.42%, corresponding to an increase of 97.22%. The highest displacement and drift values were consistently observed under soft soil conditions due to greater seismic wave amplification and increased flexibility of the soil-structure system. Although all analyzed cases satisfied the drift limitations specified by SNI 1726:2019, buildings located on soft soil sites exhibited significantly higher deformation demands. The findings demonstrate that soil classification is a critical parameter in seismic design and should be carefully considered during the planning and analysis of reinforced concrete shophouse buildings to ensure structural safety and resilience in earthquake-prone regions.

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.

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 Program (Pengabdian kepada Masyarakat/PKM) aimed to support school environmental planning through land measurement activities at SMA Negeri 1 Gunungsitoli Idanoi. The main problem faced by the partner school was the absence of accurate and well-documented land measurement data to serve as a basis for environmental arrangement and infrastructure planning. The implementation method consisted of several stages, including coordination with school stakeholders, technical preparation, direct land measurement in the field, data processing, and the formal handover of measurement results to the school. The program applied a participatory approach by involving school representatives during the measurement process as a form of technical assistance and knowledge transfer. The results showed that the land measurement activities successfully produced systematic and reliable data on land area and spatial division, which can be utilized as a foundation for school environmental management and future infrastructure development. In addition, the activity enhanced the school’s understanding of the importance of spatial data in educational environment planning. Therefore, this community service program provided practical and sustainable benefits for the school and strengthened the role of higher education institutions in supporting the improvement of educational environments.
