Abstract

The performance of a Local Area Network (LAN) greatly depends on the efficiency of the routing protocol applied. This study aims to optimize the configuration of the Open Shortest Path First (OSPF) protocol to improve LAN performance. OSPF is a dynamic routing protocol based on a link-state algorithm that calculates the shortest path using Dijkstra’s algorithm. The research method employed is simulation using Cisco Packet Tracer software. The network topology consists of multiple routers and end-devices, divided into three OSPF areas, each configured with specific IDs, subnets, and IP addresses. The configuration process includes setting IP addresses, assigning OSPF areas, and testing connectivity using ping and traceroute commands. The results demonstrate that OSPF successfully establishes full adjacency between routers, synchronizes the Link-State Advertisement (LSA) database, and ensures optimal routing paths across devices. This implementation proves that OSPF enhances efficiency, convergence speed, and network stability. The study contributes to the development of small to medium-scale LAN networks requiring optimal and reliable data traffic management. It also provides practical insight for network engineers in designing scalable and high-performance routing configurations.

Abstract

The furniture industry is undergoing a significant digital transformation, reshaping how consumers interact and make purchasing decisions. Augmented Reality (AR) technology enables users to visualise furniture products in their actual physical spaces before making a purchase, offering a more interactive, realistic, and personalised shopping experience. This study aims to evaluate the effectiveness of AR technology in supporting online furniture purchasing by applying the ADDIE development model and assessing usability through the System Usability Scale (SUS) method. A total of 35 respondents, representing millennial and Gen Z users aged between 18 untill 35, participated in testing an AR-based furniture shopping application. The research findings indicate that the application achieved an average SUS score of 81.5, which falls into the "Excellent" usability category, signifying a high level of user satisfaction and acceptance. The results also reveal that AR improves consumer confidence in product selection by allowing realistic visualisation of furniture items in users' own environments. Therefore, this study concludes that integrating AR technology in digital commerce not only enhances user experience but also provides an effective marketing strategy for furniture businesses to strengthen customer engagement, trust, and purchase decisions in the digital era.
