Abstract

The fifth-generation (5G) network promises ultra-fast connectivity, massive device density, and low latency, yet ensuring reliable Quality of Service (QoS) remains a major challenge. This study conducts a Systematic Literature Review (SLR) of 35 peer-reviewed articles published between 2020–2023, sourced from IEEE Xplore, Scopus, and Google Scholar. The review identifies key QoS mechanisms such as network slicing, resource allocation, and latency management, while challenges persist in scalability, interoperability, and security. Emerging trends highlight the growing role of Artificial Intelligence (AI), Machine Learning (ML), and Software-Defined Networking (SDN) for QoS optimization. In Indonesia, regulatory readiness, spectrum allocation, and uneven infrastructure present both challenges and opportunities. The study contributes by synthesizing recent findings, outlining research gaps, and offering practical insights for policymakers, operators, and researchers.

Abstract

This study examines the application of UI/UX principles to the "Journeys" mobile application to improve accessibility for MSMEs in the tourism sector, using the User-Centered Design (UCD) approach. Digital transformation in today's era offers great opportunities for MSMEs to promote their products and services to a wider audience. The UCD methodology, supported by the User-Based Collaborative Filtering system, is the core of designing an application that is aligned with user needs. The research phase involved user surveys and Focus Group Discussions (FGD) to explore needs, which were then manifested in user personas and customer journey mapping. The UI/UX design was prototyped with Figma, resulting in intuitive interfaces for the welcome screen, login, user profile, as well as destination exploration, social interaction, and itinerary planning features. The "My Ratings" and "Forge Your Route" features demonstrate a commitment to usability principles and community-based content integration. The "Journeys" application is expected to encourage the digital growth of tourism MSMEs and expand their market reach, support the development of local tourism human resources and the effectiveness of digital promotion. Evaluation using the System Usability Scale (SUS) showed an average score of 90,75 placing the application in the "Excellent" category and confirming its ease of use.
