Earthquake Disaster Capacity Analysis and Mitigation through Geographic Information System (GIS) Mapping: A Case Study of Unjani Cimahi Campus

Abstract

Background and Aims: Universities have a strategic role in building disaster preparedness capacity, particularly in the context of climate change and the increasing intensity of natural disasters in Indonesia. As a higher education institution, Jenderal Achmad Yani University (Unjani) has a responsibility to ensure a safe environment for its academic community. This study aims to map disaster risks at Unjani by 2025 to increase campus resilience to potential disaster threats. Methodology: This study employed a qualitative approach using Geographic Information Systems (GIS)-based spatial mapping and risk analysis, including the identification of hazards, vulnerabilities, capacities, and disaster impacts. Data were collected through surveys, stakeholder interviews, and analysis of campus policy documents related to disaster management. Result: In the context of UNJANI, the campus area is generally located in a low landslide vulnerability zone around the campus centre and a medium vulnerability zone on the southern and eastern edges. The medium vulnerability zone indicates that landslide potential can increase if slope disturbances occur, such as unstable slope cutting or extreme rainfall conditions. This finding has important implications for campus area management, particularly in development planning, geotechnical research, and the evaluation of slope stability and building foundations to support sustainable disaster mitigation efforts. The high hazard index across the UNJANI area indicates that, regardless of the campus's distance from the earthquake source, the characteristics of the underlying ground, such as the presence of soft soil or a relatively thick layer of sediment, have the potential to amplify seismic waves. This can result in more intense surface shaking and potentially greater damage to campus infrastructure. Interview findings indicate the importance of implementing sustainable building maintenance management as an integral part of disaster risk mitigation efforts. Conclusion: The study confirms that disaster risk reduction efforts in campus environments depend not only on the strength of building structures, but also on the awareness of managers in maintaining facilities, providing a complete evacuation information system, and ensuring that buildings continue to meet safety standards over time.
