Abstract

One of the network instabilities is bandwidth traffic. Therefore, it is necessary to analyze monitoring and QoS on synchronous and asynchronous computer networks by measuring QoS to overcome these problems. QoS (Quality of Service) measurement is carried out so that internet users can find out whether the quality of internet services they get is good or not. Monitoring and QoS on synchronous and asynchronous computers at pmi muara enim emphasizes the process of monitoring and measuring network quality parameters on internet network infrastructure such as access speed and transmission capacity, work, from the sender point to the destination receiver point. Based on the results of the Quality of Service (QoS) analysis on the WLAN network, it can be concluded that Packet Loss is included in the “Very Satisfactory / Very Good” category with an index of 4. Delay: Also falls into the “Very Satisfactory / Very Good” category with an index of 4. Jitter: Falls into the “Satisfactory / Good” category with an index of 3. With a percentage of QoS value of 91.66%. So based on the percentage obtained, the quality of WLAN network services falls into the “Satisfactory” category. This shows that the network can provide good performance in terms of managing packet loss, delay, and jitter so that the user experience is considered very good and meets the applicable TIPHON standards.

Abstract

This study aims to analyze and compare the User Interface (UI) and User Experience (UX) of three online transportation applications in Palembang City, namely Gojek, Grab, and Maxim. The rapid growth of Indonesia’s online transportation industry, which reached 88.3 million users in 2024, highlights the importance of evaluating usability quality. Palembang has unique geographical characteristics, as the city is divided by the Musi River, creating specific challenges for app-based transportation services. The novelty of this study lies in the integration of the System Usability Scale (SUS) with Nielsen’s heuristic evaluation within an urban geographical context fragmented by natural barriers. A descriptive comparative approach was employed, involving 120 active users and three UI/UX expert evaluators. The results show that Gojek achieved the highest SUS score of 78.5 (Good), followed by Grab with 75.2 (Good) and Maxim with 68.7 (OK). One-Way ANOVA indicates significant differences among the applications (F = 12.847; p < 0.001). Theoretically, these findings demonstrate that an integrated usability evaluation approach provides a more comprehensive understanding of UI/UX quality in geographically specific contexts.
