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

The rapid development of digital technologies and advanced material innovations has transformed the field of modern civil engineering. This study examines the integration of smart infrastructure systems with innovative construction materials to enhance structural performance, sustainability, and resilience. Using a mixed-methods approach, the research combines expert interviews, case studies, and quantitative data from 30 infrastructure projects implemented between 2018 and 2024. The results indicate that smart infrastructure equipped with real-time monitoring, IoT sensors, and AI-based predictive analytics significantly reduces maintenance frequency by up to 40% and improves reliability through early detection of structural anomalies. Meanwhile, innovative materials such as self-healing concrete, fiber-reinforced polymers (FRP), and geopolymer composites demonstrate substantial improvements in durability, mechanical strength, and carbon footprint reduction—achieving up to 70% lower CO₂ emissions compared to traditional materials. Life cycle assessments further confirm the long-term economic benefits of implementing smart and sustainable systems, despite higher initial investment costs. The study concludes that the integration of intelligent technologies and next-generation materials constitutes a paradigm shift that supports global sustainability goals, enhances infrastructure resilience, and drives the transition toward smarter, greener urban environments.

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.
