RANCANG BANGUN SISTEM KOMUNIKASI MENGGUNAKAN VOIP BERBASIS OPEN SOURCE ANTAR UNIT KERJA DI POLITEKNIK PENERBANGAN SURABAYA

Abstract

Voice Over Internet Protocol (VOIP) is a technology that facilitates rapid and efficient communication and information exchange. This technology converts analog voice into digital data and transmits it through the Internet network. At Surabaya Flight Polytechnic Campus, the communication system between units still relies on personal phones and the Public Switched Telephone Network (PSTN), which proves inefficient due to limitations in personal phone numbers and dependence on cable infrastructure. This study aims to develop an open source Briker-based VOIP communication system using the Surabaya Flight Polytechnic's WiFi network. With this development, the open source Briker-based VOIP communication system offers a more efficient solution for inter-unit communication at Surabaya Flight Polytechnic, potentially enhancing service quality and reducing reliance on traditional cable infrastructure. The research method used is the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) approach to design and implement the Briker-based VOIP communication system in the Integration Lab. The system's testing involves analyzing Quality of Service (QoS) metrics such as delay, jitter, and packet loss, measured through testing between two users in five trial runs. The test results show that VOIP communication using open source Briker can run on a softphone with QoS results meeting TIPHON standards, with the highest delay value reaching 20.52 ms, the highest jitter value at 20.32 ms, and a packet loss of 1.21%. Product validation also averaged 95.33% with a "strongly agree" criterion.
