Assessing Disaster Mitigation System Readiness in Building Construction Using Wireless Network Systems: An Exploratory Factor Analysis

Abstract

The increasing frequency of natural disasters demands effective early warning and mitigation systems, especially in disasterprone regions. This study explores the readiness to implement Wireless Network System (WNS)-based disaster mitigation in building construction through Exploratory Factor Analysis (EFA). A structured Likert-scale questionnaire was administered to 15 professionals involved in construction and disaster management in Trenggalek Regency, Indonesia. Principal Component Analysis (PCA) with Varimax rotation was used to identify the latent constructs behind system readiness perceptions. The analysis revealed a three-factor structure: Technological Readiness and Usage Attitude, Information Quality and System Interaction, and Perceived Usefulness. These dimensions explain the majority of variance in the dataset and highlight the key areas of concern in adopting WNS in real-world construction practices. The findings contribute to better system planning and policy development in the context of disaster-prone infrastructure.
