Abstract

Virtual Private Network (VPN) is a form of private network through a public network by focusing on the security of the encrypted data in it. This research uses Cisco Packet Tracere software as a computer network technology simulation tool. Cisco Packet Tracker is a device in network technology simulation that functions for creation and development in networks. The purpose of this research is to create a VPN simulation using a star topology with Cisco Packet Tracer software. Star topology is a star-shaped topology, where each node is to the centre. The method used is a qualitative method with data collection techniques or Literature Study, namely looking for references from the internet in the form of journals. In creating a VPN simulation using Cisco Packet Tracer requires hardware in the form of a server, router, switch, and PC or computer.

Abstract

Traffic congestion is a major challenge in many big cities, including Serang City, Banten Province. This study aims to optimize vehicle flow at a four-way intersection using a traffic light system based on Omron CP1L Programmable Logic Controller (PLC). The research method involves simulation and hardware experiments to analyze traffic efficiency. The simulation results show that the PLC system can adjust the duration of traffic lights based on vehicle density, thereby reducing queues and increasing vehicle flow efficiency. This study concludes that the PLC-based approach is effective for more dynamic traffic management and recommends further improvements to the design aspects of indicator lights to ensure signal clarity for road users.
