Abstract

The increasing number of motor vehicles has been accompanied by a rise in vehicle-related crimes, highlighting the need for more advanced and adaptive security systems. Conventional vehicle security systems are limited by their inability to provide real-time monitoring and accurate intrusion detection. This study aims to develop and evaluate an Internet of Things (IoT)-based vehicle security system that integrates multiple sensors to improve detection accuracy and responsiveness. The research employs a Research and Development (R&D) Level 3 approach, involving system design, development, and performance testing. The proposed system utilizes a combination of piezoelectric sensors for vibration detection, glass break sensors for acoustic detection, and a GPS module for real-time tracking, all controlled by an ESP32 microcontroller and connected to a Telegram-based notification system. The results indicate that the multi-sensor integration enhances the system’s ability to detect various intrusion patterns more accurately while minimizing false alarms compared to single-sensor systems. Additionally, real-time notifications and location tracking improve user responsiveness to potential threats. In conclusion, the developed system provides a more effective, accurate, and adaptive vehicle security solution suitable for modern security challenges.

Abstract

This study profiled the critical thinking disposition of early-year science education students and examined preliminary psychometric evidence of an Ennis-based questionnaire. A quantitative descriptive survey with preliminary psychometric analysis was conducted with 90 second-semester science education students from three universities in West Nusa Tenggara Province, Indonesia. Data were collected using a 36-item questionnaire organized into 12 indicators of critical thinking disposition. Negatively worded items were reverse-scored before analysis. Descriptive statistics, category distribution, indicator-based profiling, Cronbach’s alpha, corrected item-total correlation, and exploratory factor analysis based on 12 indicator scores were applied. The results showed that students’ critical thinking disposition was generally moderate, with nearly all participants located in the moderate category. The highest indicator scores were found in precision required by situation, total situation, and employing critical thinking abilities, while the lowest scores were found in clear reasons, credible sources and observations, and being well-informed. The corrected internal consistency was modest, and several negatively worded items showed weak item-total correlations. The exploratory factor analysis suggested a tentative three-factor structure: evidence-based reasoning disposition, contextual and reflective judgment, and self-regulated critical engagement. These findings indicate that students’ critical thinking disposition is still developing and that the questionnaire requires further refinement.
