Abstract

The quality of the Wi-Fi network plays an important role in supporting academic activities at the Faculty of Engineering, Muhammadiyah University of Bengkulu. This study aims to analyze Wi-Fi network performance using the Quality of Service (QoS) method based on parameters like throughput, packet loss, delay, and jitter. Measurements were taken on six access points located on the 1st, 2nd, and 3rd floors during busy and quiet hours using the Wireshark application. The measurement results were analyzed and compared with TIPHON standards to determine network quality. The research results showed that the average throughput value of 770.19 Kbps falls into the Fair category, packet loss at 0.01% is in the Very Good category, delay of 32.49 ms is in the Very Good category, and jitter of 32.65 ms is in the Good category. Based on this analysis, an average index of 3.25 was obtained, so the overall Wi-Fi quality at the Faculty of Engineering, Muhammadiyah University of Bengkulu is in the Good category according to TIPHON standards and can support academic activities.

Abstract

The process of recording teacher attendance at SD Negeri 50 Kota Bengkulu still uses an attendance book, resulting in manual data management. This study aims to develop a web-based teacher attendance system using QR Code and location validation. Data were obtained through observation, interviews, and literature study. The system was developed using the Waterfall method with PHP and MySQL and Visual Studio Code. The admin can manage teacher data, schedules, QR Codes, attendance data, and reports, while teachers record their attendance by scanning the QR Code and logging in using a username and password. The system automatically displays the schedule and validates the attendance time and location based on a predetermined polygon area. The system also limits attendance recording to once per day and provides a 15-minute late tolerance. The implementation results show that the system can perform attendance recording, location and time validation, data storage, and report generation, which can be printed and exported to Excel. Testing using Black Box Testing shows that the main system functions operate according to the requirements. The developed system can assist the school in digitally recording and managing teacher attendance and provide data for administrative needs.
