Core Subject :
The International Journal of Disaster Management (IJDM) is an international, peer-reviewed, open-access journal dedicated to advancing knowledge and practice in disaster management, disaster risk reduction, and resilience. The journal provides an interdisciplinary platform for researchers, practitioners, policymakers, and professionals to address contemporary disaster risks and their implications for communities and society. IJDM publishes original research and scholarly contributions covering disaster risk reduction and management; disaster preparedness, response, recovery, and reconstruction; disaster governance and policy; disaster and risk communication; early warning systems; hazard, vulnerability, and risk assessment; community-based disaster risk reduction; climate-related hazards and adaptation; community resilience; indigenous and local knowledge; social, cultural, and psychosocial dimensions of disasters; disaster education and capacity development; geospatial and technological applications; resilient infrastructure; and interdisciplinary and transdisciplinary approaches to disaster studies. The journal particularly encourages research that connects scientific knowledge with policy and practice and contributes to reducing disaster risk and strengthening resilience across diverse geographical, social, and cultural contexts.

Abstract

Flooding in the Bekasi River Basin, West Java, Indonesia, is now more frequent and destructive. This is due to rapid urbanisation, land‑cover change, and intensified rainfall. Conventional early warning systems rely on sparse rain‑gauge networks and manual reporting. This leads to limited coverage and delayed responses, such as during the March 3–4, 2025 flood event. To address these issues, this study presents a real‑time, satellite‑enabled flood forecasting framework. It integrates precipitation estimates from GSMaP with the Universitas Pertamina Rainfall–Runoff Model. Near‑real‑time GSMaP_NOW and GSMaP_NRT products, at 0.1° spatial resolution and hourly intervals, are assimilated into a semi‑distributed hydrological model. This model runs continuously to generate 24‑hour river discharge forecasts at multiple monitoring locations. When applied to the March 2025 flood event, the simulated discharge captured the timing of flood onset and escalation. Alert Level‑1 thresholds were identified about one hour in advance at Cileungsi station. At the watershed scale, upstream rainfall detection gave a five to six-hour lead time before downstream flooding. These results show that satellite‑based rainfall monitoring combined with real‑time hydrological modelling can support operational flood warning in data‑sparse urban watersheds.

Abstract

This study examines the role of open spaces as evacuation sites during disasters caused by natural hazards in Indonesia, a country highly exposed to earthquakes, floods, and tsunamis. Urban open spaces are considered not only essential for everyday urban activity but also critical refuges during emergencies. A cross-sectional online survey was conducted with 109 students from the Institut Teknologi Sumatera to explore evacuation behavior and related perceptions. The survey comprised three components: (1) disaster knowledge and experience, including prior education and evacuation drills; (2) perceived safety of residential environments; and (3) evacuation strategies, including timing, site selection, and mode of movement. The findings indicate that during earthquakes, most respondents immediately evacuate outdoors and tend to remain at their initial location rather than relocate over time. Results also elucidate limited hands-on evacuation drill experience despite prior disaster education, highlighting gaps between knowledge and practical preparedness that may constrain the effective identification and use of safe evacuation sites. Open spaces function as multifunctional environments, providing protection from structural hazards while serving as informal hubs for information and social support. The study underscores the need for integrated urban planning and preparedness strategies that strengthen both accessible open-space provision and community-based evacuation capacity to enhance urban disaster resilience.

Abstract

Slope instability along reservoir banks is an important but often overlooked source of sediment entering reservoirs during water-level fluctuations. Previous sedimentation assessments in Keuliling Reservoir mainly considered watershed erosion and did not explicitly quantify the contribution of reservoir-bank slope failures. This study investigates the potential sediment contribution from unstable reservoir slopes induced by water-level drawdown. Field observations, soil sampling, and laboratory shear tests were conducted in three landslide-prone zones around the Keuliling Reservoir, Aceh Province. Slope stability was evaluated using a limit equilibrium framework under different water-level drawdown scenarios ranging from 0.2 to 2.4 m. The results indicate that slope stability decreases significantly as water levels decline. Zones A and C exhibit unstable conditions with average safety factors of 0.52 and 0.99, respectively, while Zone B remains relatively stable with an average safety factor of 2.92. Potential sediment contribution from unstable slopes was estimated using a sediment transport approximation adapted from classical bed-load theory to represent possible mobilized material during slope failure. The analysis shows that reservoir drawdown can substantially increase slope instability and may contribute additional sediment to the reservoir storage. These findings highlight the importance of incorporating reservoir-bank instability into sediment management, operational decision-making, and disaster risk reduction strategies in reservoir systems. The results provide useful insights for reservoir operation planning, particularly in establishing safer drawdown rates and slope monitoring strategies.

Abstract

Seasonal and upstream-induced flooding in Samarinda, Indonesia, has increasingly affected cultural heritage structures, including the Lamin Pemung Tawai in Pampang Village. Existing studies on stilt dwellings have primarily focused on riverine, coastal, or marsh-based environments and generally interpret elevation as an intentional adaptation to flood hazards. This study investigates a forest-based communal stilt house whose elevation was not originally intended for flood adaptation but now functions as an inherited capacity under increasing flood exposure. Using the Hazard–Exposure–Vulnerability–Capacity (HEVC) framework, the study combines field observations, semi-structured interviews with 11 respondents conducted over 15 interview sessions, and Justified Graph spatial analysis. The findings reveal vulnerabilities associated with water accumulation beneath the structure, uneven structural reinforcement, low-clearance underfloor spaces, and the absence of formal emergency procedures. At the same time, the building's elevated timber structure, open underfloor configuration, accessible spatial layout, and strong social capital provide significant adaptive capacities. The Lamin's central hall and multi-access spatial configuration also facilitate collective gathering, temporary refuge, and emergency coordination during flood events. The study demonstrates how a forest-based communal stilt house can acquire adaptive functions while maintaining its cultural identity, highlighting the potential of vernacular heritage structures to serve as community-based disaster risk reduction assets under changing environmental conditions.

Abstract

Two decades after the 2004 Indian Ocean Tsunami, Banda Aceh remains highly vulnerable to tsunami hazards, making evacuation preparedness a critical component of disaster risk reduction. This study examines factors influencing tsunami evacuation intention among residents of Banda Aceh using a convergent mixed-methods design integrating survey data (N = 381) and focus group discussions (n = 35). Quantitative data were analysed using descriptive statistics, Pearson correlations, and binary logistic regression, while qualitative data were examined through inductive thematic analysis. The results show that trust in the tsunami early warning siren system significantly predicts immediate evacuation intention (OR = 1.39, p = .020). Descriptive findings also reveal preparedness gaps, including low participation in tsunami drills and limited ownership of emergency preparedness kits. Qualitative insights further highlight the influence of social norms, religious interpretations of disasters, and institutional trust in shaping evacuation decisions. These findings suggest that strengthening tsunami preparedness requires integrated approaches combining reliable early warning systems, culturally sensitive risk communication, and community-based preparedness initiatives.
