Abstract

This research aims to create an educational environment integrated with technology through the implementation of educational technology, particularly by managing and storing digital learning device documents known as repositories. The developed Repository System aims to optimize storage management for learning device documents within an educational institution. A case study was conducted at a Vocational High School (SMK). The management and storage system for learning device documents was developed using the Personal Extreme Programming (PXP) method, adopting an adaptive and flexible agile approach. The repository system also applies data compression technology to optimize the storage capacity of learning device documents. Based on the results of the data compression testing, the developed system proved to be suitable, achieving an average storage efficiency of 40.04% for each uploaded file. This research contributes practical insights into the implementation of a repository system in an educational environment, particularly in Vocational High Schools, with a focus on curriculum transitions and the efficiency of managing learning device documents.

Abstract

This research aims to develop a desktop application for Monitoring Ships and storing data from the Automatic Identification System (AIS) utilizing Realtek Software Defined Radio (RTL-SDR) and Raspberry Pi devices. The development method employed is the waterfall model, using Python and PyQt as the main programming languages. Black-box testing was conducted on the application, covering aspects such as decoding AIS messages, real-time monitoring, historical data storage, and statistical analysis of the data. The test results indicate that the application successfully addresses challenges faced by the simple AIS receiver, achieving the research objectives by accurately decoding AIS messages, monitoring ship journeys in real-time, storing AIS data as historical data, and presenting informative statistical data. Despite some lag, especially on the Raspberry Pi device, the application contributes positively with improved accuracy and functionality. Further evaluation, technological updates, and integration with other devices are expected to enhance the application's performance. The use of Python and PyQt provides a foundation for further development to enhance the quality of ship navigation systems. It is recommended to involve the decoding of other AIS message types in future research and to consider building a ship journey simulation system for an interactive user experience.

Abstract

The Web-Based Student Violation Point Information System (SIMPONIS) was developed to enhance the efficiency and transparency of recording and monitoring student violations at SMA Negeri 1 Ranah Pesisir. This system is designed to replace the previous manual method, which was prone to errors, data duplication, and delays in handling violations. Through SIMPONIS, guidance counselors can record and monitor student violation points in real-time and provide accurate reports to students and parents. The system integrates an Early Warning Feature that alerts users when a student’s violation points reach a critical threshold, allowing for corrective actions to be taken promptly. The system was tested using the black box method, ensuring that all functions operate as expected. The test results show that SIMPONIS provides an effective solution for managing student violation data, increases parent involvement in monitoring their children, and simplifies the administrative tasks of guidance counselors. Therefore, this system has the potential to be implemented more broadly in other educational institutions.
