Mass Movement Risk Assesment as the Basis for Disaster Mitigation at Petirtaan Belahan Site in Pasuruan Region Penilaian Risiko Gerakan Tanah sebagai Dasar Mitigasi Bencana di Situs Petirtaan Belahan Kabupaten Pasuruan

Abstract

The Petirtaan Belahan Site area, located in Pasuruan Regency, East Java, is a designated cultural heritage site. Such sites are finite in number, unique, and non-renewable, thus highly vulnerable to damage which makes protecting them from the threat of disasters risk essential. This research explores on how to assess disaster risk in the Petirtaan Belahan Site area and what mitigation efforts can be undertaken. A qualitative research approach was used with data collected through field observations, map document studies, interviews, and literature reviews. The data used include Cunggrang Inscription, Kakawin Negarakertagama, environmental condition maps, scientific literature, and interview results. Findings shows that the site holds significant importance for history, education, economy, and religion, thus its existence must be preserved. The site faces low to moderate hazards, primarily triggered by rainfall conditions and land use changes. Vulnerability linked to the structures and the absence of adequate reinforcement systems, while disaster preparedness capacity has not been optimized. To address these risks, disaster mitigation efforts can be implemented through slope reinforcement with soil conservation, land management, provision of preparedness facilities, and community involvement in education and disaster response teams.
