Abstract

People's need for internet connection is a must nowadays, as everyone surely performs all activities through the internet. All activities require internet connection, be it work, lectures, gaming, household payments, shopping and many other activities that are done online. However, because people still rely on the experiences of other users when choosing Internet providers, it is difficult to find a fiber Internet service provider whose quality of service meets one's needs. The decision support system can help people choose an Internet service provider efficiently. The decision support system for fiber optic Internet service provider selection uses the weighted product method, which is one of the methods in the decision support system. The weighted product method is considered suitable to determine the best fiber optic internet service provider in North Jakarta with the appropriate weighting. The stages of the weighted product method include determining the priority value of each criterion, calculating the weight of the criterion, calculating the vector Si, calculating the vector Vi, and making the decision based on the results of the vector Vi calculations. The largest Vi value is the best alternative option. The results of this study are proven to be able to provide an objective alternative for choosing the best Internet service provider in the North Jakarta area.

Abstract

This study examines the development and deployment of a remote access management system by integrating Defguard with the WireGuard VPN at PT. Esta Dana Ventura. The company previously faced unstable connections and inefficient user administration due to the limitations of its MikroTik-based PPTP and L2TP VPN solutions. To overcome these challenges, a new architecture was designed using WireGuard for its lightweight performance and Defguard for centralized and streamlined access control. The system was implemented within a Docker environment and evaluated using key performance indicators such as latency, throughput, packet loss, and connection stability across multiple internet service providers. The results demonstrated that the WireGuard-based configuration delivered lower latency, zero packet loss, and secure connections without DNS leakage, while token-based authentication significantly simplified user management. Overall, the new system enhanced connection reliability, improved security, and provided scalable remote access for geographically distributed users, making it an effective replacement for the legacy VPN infrastructure.
