Calamity: A Journal of Disaster Technology and Engineering
ISSN : -     EISSN : 30254140     DOI : -
Calamity: A Journal of Disaster Technology and Engineering focuses on unique research on all facets of natural hazards, such as the prediction of catastrophic events, risk management, and the nature of natural and manmade hazard precursors. The effects on the environment are equally disastrous even if risks might come from a variety of sources and systems, including atmospheric, hydrologic, oceanographic, volcanologic, seismic, and neotectonic. This calls for tight collaboration between many scientific and operational disciplines in order to improve risk reduction. Risk assessment is included in the coverage of hazards in the atmospheric, climatological, oceanographic, storm surge, tsunami, flood, snow, avalanche, landslide, erosion, volcanic, man-made, and technology categories.

Abstract

Background: In construction work, occupational accidents remain one of the most critical issues in the construction industry, particularly in housing development projects that involve various high-risk activities. An occupational accident is an undesired and unexpected event that occurs in the workplace, resulting in worker injuries, equipment damage, workflow disruption, or even fatalities. Methods: This study aims to analyze the probability of work accidents using the Hazard and Operability Study (HAZOP) approach to identify potential hazards and operational failures in each stage of construction work at the XYZ housing project. The method is applied to systematically review various risk scenarios based on field observations, interviews, and available safety documentation. Findings: The HAZOP analysis successfully identified six critical hazards in the XYZ housing development project, including material-related accidents, falls from heights, heavy material intrusion, and respiratory disorders from dust, primarily caused by worker negligence, lack of proper procedures, and inadequate use of PPE. Conclusion: The implementation of integrated preventive measures such as the provision of complete PPE, structured SOP development, continuous training, and strict supervision has proven to be an effective strategy in mitigating occupational accident risks in construction environments. Novelty/Originality of this article: This study presents a systematic HAZOP-based approach combined with the 5S methodology and enhanced SOP enforcement as a practical and replicable model for risk evaluation in residential construction projects.

Abstract

Background: This research was conducted in Lebakharjo Village, Malang Regency. Malang Regency is prone to flooding due to high rainfall, with Lebakharjo Village being one of the affected areas. In July 2023, the village experienced another flood, damaging 119 houses and cutting off access to the village, leaving the village isolated. The purpose of this study was to assess the level of community preparedness in Lebakharjo Village for flood disasters. Methods: This study used a quantitative descriptive method with multiple correlation tests and multiple linear regression. Data collection was carried out by distributing questionnaires to respondents selected from flood-prone areas in Lebakharjo Village door to door. Findings: Data tabulation showed that 66 people, or 67.35%, were in the medium preparedness category, while 32 people, or 32.65%, were in the high preparedness category. This indicates the need for disaster preparedness training or evacuation simulations to improve community preparedness for floods. Knowledge and attitude significantly influence community preparedness in Lebakharjo Village for floods. The combined effect of Knowledge (X1) and Attitude (X2) variables on Community Preparedness (Y) is 28.5%, while the remaining 71.5% is influenced by other variables not covered in this study. Conclusion: This study highlights that increasing knowledge and attitudes through targeted interventions can improve flood preparedness in the Lebakharjo Village community. Novelty/Originality of this article: This study uniquely quantifies the impact of knowledge and attitudes on flood preparedness in the village, highlighting the need for targeted community training to improve preparedness.

Abstract

Background: Infrastructure preparedness during disasters depends greatly on the successful and timely execution of government construction projects, particularly multi-story buildings that function as critical public facilities. However, in practice, many of these projects experience tender failures due to significant price deviations from the Owner’s Estimate (HPS), either through underpricing or overpricing. These failures often result in delays or cancellations, disrupting the availability of essential infrastructure in emergency scenarios. Methods: This study applies the Failure Mode and Effect Analysis (FMEA) method to systematically identify, assess, and prioritize the underlying causes of tender failure in a government-funded multi-story building project. Data collection involved document analysis, expert validation, and structured questionnaires focusing on three key parameters: severity, occurrence, and detection of each failure mode. Findings: The results reveal two major categories of failure factors: issues related to documentation and problems in cost estimation. Documentation issues include unclear specifications and lack of expert personnel due to limited preparation time, while cost estimation problems involve insufficient market analysis, unrealistic pricing, and scheduling errors. The highest Risk Priority Numbers (RPNs) were found in the indicators “failure in offering strategy” (RPN = 22.944), “failure in prequalification” (RPN = 22.874), and “lack of expert personnel due to limited time availability” (RPN = 22.032), all of which are considered critical and indicative of systemic vulnerability in the tendering process. These critical failures highlight the potential risk they pose to infrastructure readiness, especially in disaster-prone contexts. Conclusion: Tender failures caused by price deviation pose a systemic risk to infrastructure preparedness. Reforming public procurement systems with improved risk identification and mitigation strategies—especially in document and cost estimation processes—is essential for supporting disaster-resilient infrastructure development. Novelty/Originality of this article: This study is one of the first to link FMEA-based tender risk assessment with disaster preparedness outcomes, offering a novel contribution to both construction management and resilience planning.
