Abstract

Background: Landslides are natural disasters that often result in significant human and material losses, especially in areas with unstable topography. In Jombang Regency, East Java, a major landslide occurred on January 28, 2014, killing 14 people and destroying infrastructure. This study aims to examine the level of disaster preparedness among the local community of Kopen Hamlet in anticipation of future landslides. Methods: This research employed a quantitative approach using survey and interview methods to collect primary data. A preparedness index was used to measure the readiness level of residents, while the Kolmogorov-Smirnov method was applied to test the normality of the data distribution based on demographic variables such as gender, age, and education. Findings: The study found that 68% of respondents were classified as sufficiently prepared, and 69% were nearly prepared depending on demographic factors. The Kolmogorov-Smirnov test yielded an Asymp. Sig (2-tailed) value of 0.063, indicating that the data were normally distributed. Preparedness levels were relatively consistent across different community groups. Conclusion: The results highlight the importance of demographic factors in community disaster preparedness and provide a foundation for targeted risk reduction interventions in similar vulnerable areas. Novelty/Originality of this article: This study uniquely integrates a preparedness index with demographic analysis in a post-disaster context, offering empirical insights from a localized rural community that has received limited prior research attention in Indonesian landslide risk studies.

Abstract

Background: Occupational accidents remain a persistent issue in the construction sector, often associated with various risk factors including worker fatigue. This study aims to analyze the effect of fatigue on the incidence of work accidents in construction projects. Previous studies have shown that fatigue can impair concentration and reaction time, leading to increased accident risks. Methods: This research employed a quantitative descriptive method with data collected through structured questionnaires from 34 construction workers. The data were analyzed using regression analysis. Additionally, instrument testing included validity tests, reliability tests, and linearity tests to ensure the accuracy and consistency of the data. Findings: The results demonstrated that worker fatigue has a significant effect on the occurrence of work accidents (p < 0.05). Factors such as long working hours, insufficient sleep, and heavy workload contributed to fatigue, which in turn increased accident potential. These results align with existing theoretical frameworks linking physical exhaustion to unsafe behaviors and reduced awareness. Conclusion: Fatigue significantly influences the frequency of workplace accidents in construction environments. Effective management of work schedules and adequate rest is essential to minimize these risks. Novelty/Originality of this article: This study offers a statistically validated perspective on the influence of fatigue on construction-related accidents, supported by rigorous instrument testing to ensure reliability and precision of findings, which contributes new empirical evidence to occupational safety literature.
