Prototype radius server wifi koin (WIKO) at PT SIMS using the evolutionary prototype method

Abstract

PT Sarana Insan Muda Selaras (PT SIMS) is a company engaged in the technology sector, specifically in providing internet network services. One of the company's products is the WiFi Koin service, which allows users to access the internet based on a certain duration of time through a prepaid voucher system. PT SIMS faces obstacles in its WiFi Koin service due to the decentralized voucher management system, which requires users to purchase new vouchers at each location. The purpose of this research is to Create a RADIUS Server Prototype to centralize the management of WiFi Koin voucher data across all PT SIMS locations. The research method used is Evolutionary Prototype, by integrating Mikrotik Routers at each location as Network Access Servers (NAS) with a central server. This central server runs the User Manager package as a RADIUS Server and utilizes Point-to-Point Tunneling Protocol Virtual Private Network (VPN) technology to bridge secure communication between locations. The results of the research show that the developed Prototype successfully centralizes the Authentication, Authorization, and Accounting (AAA) functions, allowing users to use a single voucher across the entire WiFi Koin network. Functional testing proves that the system can handle user authentication.
