Abstract

The need for high network traffic in Indonesia with the challenge of geographical topology that is difficult to reach makes the majority of internet network users access via wireless networks with limited budgets, resulting in poor internet QoS in Indonesia. An available solution to optimize low-cost network quality is to use the OpenWRT, open source router operating system with a focus on ease of application implementation in network projects. Another solution is pfSense, which is an open source router operation with a firewall network security focus to prevent intrusion. These two operating systems have different comparison methods in performance testing, making it difficult to make decisions about the performance differences between the two operating systems. This study aims to analyze the difference in performance and significance of open source operating systems with different development focuses on low-cost wireless network services. Analysis obtained from the quality of service measurement method on OpenWRT and Pfsense router operating systems on users that connected to a simulated wireless network topology. Data was collected by sending data between a number of users to the server and vice versa using iperf3 and mtr tools. The data consisted of QoS parameters: troughput, delay, jitter, and packet loss. The data shows that there are significant differences in several QoS parameters in the service of a number of users between the OpenWRT and PfSense operating systems. The results of this study show the limitations of each operating system in its implementation in low-cost wireless networks.

Abstract

This study investigates the effectiveness of using videos with subtitles to improve the pronunciation skills of ninth-grade students at SMP Al-Lathifah 2 Setu. Mastering pronunciation is a critical aspect of learning English, especially for non-native speakers. However, many students face difficulties in accurately pronouncing words due to insufficient practice and exposure. The study employed a Classroom Action Research (CAR) methodology, implemented over two cycles, to evaluate how multimedia resources, specifically videos with subtitles, can enhance pronunciation skills. The research was grounded in social learning theory, which emphasizes the role of observation and imitation in the learning process. Students engaged with videos in English, where they could simultaneously hear the correct pronunciation and view the corresponding text. The results indicated significant improvement in students’ pronunciation, with increased engagement and confidence. In the pre-cycle assessment, only 35% of students met the minimum passing criteria, but after the intervention, the passing rate rose to 90%. This improvement suggests that videos with subtitles can provide an effective tool for enhancing pronunciation, as students were able to better imitate the pronunciation patterns observed in the videos. The study highlights the potential of multimedia tools in language education and recommends their integration into teaching practices to improve English pronunciation among students.
