Abstract

USB Flash Drive is one of the most widely used storage media today, with its small shape, large capacity, and easy to carry anywhere, making USB Flash Drive the most widely used media in data exchange, along with its development, a security system is needed that can protect data stored on USB Flash Drive. The problem of this study is how to create a data security application on USB Flash Drive media? This system aims to provide data protection stored in USB Flash Drive using encryption methods, the system is created using the Delphi XE2 programming language, utilizing two Rijndael cryptographic algorithms and SHA-1 hash. The methods used in writing include data collection methods (Literature Study) and analysis methods, namely system analysis (system weaknesses, system requirements, and system feasibility). This study has succeeded in implementing a data security system for USB Flash Drive media, and testing has been carried out on the results of the implementation. Based on the results of the respondents that have been collected, it produces good response values, thus the system can provide data protection on USB Flash Drive media.

Abstract

Fire is a disaster that can cause significant material and non-material losses. Delays in detecting early signs of fire often result in the rapid spread of flames and greater damage. This study aims to implement an early fire detection and warning system based on the AVR ATmega16 microcontroller, utilizing the LM35 sensor for temperature detection, the Flame V2 sensor for flame detection, and an SMS Gateway via a Wavecom modem as a medium for remote notification. The research adopts a prototype development approach, encompassing the stages of design, implementation, and system testing. The system is designed to provide two forms of alerts: a local audio alarm and a short message service (SMS) notification to registered user mobile numbers. System testing was conducted using the black box method to validate the functionality of both hardware and software. Experimental results indicate that the LM35 sensor successfully detected temperature increases above 39°C, while the Flame V2 sensor accurately identified the presence of fire. The system automatically transmitted SMS notifications to the user and activated a buzzer alarm as a danger alert. Furthermore, users were able to control the activation and deactivation of sensors via SMS commands with specific formats, thereby enhancing the system’s operational flexibility. This study is expected to serve as a foundation for further development toward more intelligent, integrated, and adaptive fire detection systems.
