Abstract

Sumber Rezeki Printing is a business entity that operates in the digital printing sector, which does setting and printing. For the Sumber Rezeki Printing transaction system, customers come with raw files and then go home with the printed results. However, the transaction system at Sumber Rezeki Printing is still carried out manually, such as in the process of creating order forms and SPK (work orders), which makes this system inefficient, especially in terms of materials and time. Based on the problems described, the author intends to create a web-based application to overcome existing problems. Therefore, the topic that will be created is "Design and Build a Web-Based Print Ordering Application at PT. Source of Fortune”.

Abstract

Virtual Private Networks (VPN) represent a popular solution for securing network access, particularly within the context of remote work and sensitive data access. However, VPN usage also affects network performance metrics such as latency and access speed. This study aims to evaluate the impact of VPNs on network security and performance utilizing a Research and Development approach. Experimental results demonstrate a 65% increase in access security alongside a 22% decrease in performance, with variations depending on the type of VPN protocol deployed. With the growing demand for personal data protection, VPNs play a vital role in maintaining privacy and securing digital communications. Nevertheless, the impact of VPN usage on network performance, specifically regarding access speed and latency, frequently remains a subject of debate. The research findings show that although VPNs can reduce access speed, newer technologies such as WireGuard and IKEv2 have mitigated these negative performance impacts. This study provides useful insights for individuals and organizations in selecting VPN services that align with their specific requirements.

Abstract

Digital transformation within campus environments via Peer-to-Peer (P2P) networks and the Internet of Everything (IoE) integration offers high efficiency and intelligent connectivity, yet introduces significant network security risks. This study analyzes these risks and designs contemporary technology-based security strategies to support Smart Campus systems. Utilizing a Research and Development approach, a hybrid security model based on adaptive encryption and AI-driven monitoring was developed. Experimental results demonstrate a 72% increase in threat detection capabilities and an average attack mitigation response time of 3.4 seconds. This article proposes a digital security transformation model built upon a P2P architecture to enhance network efficiency and resilience. Furthermore, this study examines security strategies, technological innovations, and their implementation impacts on smart campus operational efficiency. Through case studies and network simulations, this article offers a novel contribution to adaptive digital security design.
