Abstract

Video conferencing is one of the technologies widely used for learning during the Covid-19 pandemic. UIN Maulana Malik Ibrahim Malang is one of the universities that implements online learning and has a video conference platform that is connected to an electronic learning system (e-learning). However, not all students can access a smooth internet connection. This causes a decrease in the quality of video conferencing that interferes learning process. This study seeks to find ways to improve the quality of video conferencing on a limited internet connection. This research use the packet priority technique at the router to manipulate the packet queue. Video conference data packet will be prioritized upon another application data. The results of the research show that manipulating the queue of data packets on a computer network can improve the quality of video conferencing on a limited bandwidth from the delay and jitter parameters between 20% to 30%. Meanwhile, packet loss shows 0%, but packet retransmission is quite a lot in the scenario without packet priority, especially at bandwidth < 3Mbps. The results of this study indicate that the priority manipulation of data packets has an impact on reducing lag / lost information when the video conference process takes place, especially at bandwidth < 3Mbps.

Abstract

Moodle is a widely used Learning Management System in various educational institutions worldwide. However, frequent reports on internet forums indicate performance degradation when massive simultaneous users access Moodle. One of the most resource-intensive components supporting Moodle is the database, as all user-accessed data is stored in it. This study aims to optimize Moodle’s performance through distributed databases. Distributing the database into multiple database servers allows the database load to be distributed across all the database servers, resulting in an overall improvement in Moodle performance. This study compares the performance of Moodle installed on a single server with that installed on multiple database servers. Various testing parameters are employed to get valid results. Namely, course read, course write, and database performance, utilizing the server performance plugin available in Moodle. This research reveals a performance improvement of 384% in course read, 193% in course write, and 260% in the Moodle database in the multi-server scenario compared to the single-server scenario. This result validates that the database is the most crucial part of Moodle.
