Abstract

PT Integrasi Data Nusantara (ID-Networkers) is a company that provides training and certification in the field of information technology. In its implementation, the company faces issues related to the management of laptops borrowed by training participants, where there is no organized system to record the borrowing status, resulting in the risk of device loss and reduced training efficiency. To address this, a web application has been developed for monitoring, tracking, and inventorying laptop loans. This application is designed to assist warehouse administrators in recording and tracking device status in real-time, as well as ensuring the timely return of laptops. The methods used in the development of this application include literature review, system requirement analysis, and system testing by distributing questionnaires to application users. The testing results show that this application can enhance the efficiency of device management, minimize the risk of laptop loss, and support the smooth running of training programs. With this application, it is expected that PT Integrasi Data Nusantara can better manage its devices, improve training efficiency, and ensure optimal device availability for training participants.

Abstract

Network security plays a crucial role in supporting productivity and ensuring operational continuity within Small Office/Home Office (SOHO) environments. However, limitations in infrastructure and technical resources often hinder the implementation of reliable and efficient security solutions. This study aims to optimize network security through a centralized VPN connection approach using ZeroTier technology. ZeroTier is a peer-to-peer-based virtual network solution that supports end-to-end encryption using the AES-256-GCM protocol and public key authentication based on Curve25519. It enables secure connections between computers within a virtual local network, even if they are physically located in different places. This research employs an experimental methodology by comparing two scenarios: a SOHO network without VPN and a SOHO network with centralized VPN connectivity using ZeroTier. The evaluation focuses on security parameters (encryption, authentication, and secure routing), network performance (latency and throughput), and ease of implementation. The results show that implementing ZeroTier significantly enhances data communication security without requiring additional physical infrastructure. Furthermore, the centralized connection scheme offers centralized traffic control, simplifies access management, and reduces potential vulnerabilities from uncontrolled peer-to-peer connections. In conclusion, the application of centralized VPN connections using ZeroTier proves effective in optimizing network security for SOHO environments through a lightweight, efficient, and easy-to-implement approach.
