The role of the Air Traffic Controller (ATC) as a regulator of flight traffic at the airport is very important in guiding pilots while running planes in the air. ATC provides information needed by pilots when the aircraft is in the controlled system area, such as weather information, flight navigation information, and air traffic information. In conducting its operations, ATC uses voice communication as the main tool in controlling flight traffic. One component of ATC that provides voice and recording communication facilities on all Working Position Controllers (CWP) such as Tower Controller, Approach Controller, Area Controller is Voice Switching Control System (VSCS). The dominant VSCS technology currently uses analog-based Circuit Switching (CS) and Time Division Multiplexing (TDM) technologies. Along with the development of computer-based systems and information technology based on Packet Switching (PS) technology that uses TCP / IP protocols, the complex and expensive VSCS systems with CS technology can be replaced with more modern and inexpensive systems based on Voice over IP (VoIP). This thesis discusses the solution for developing and measuring the performance of IP-based VSCS prototypes using VoIP technology. The results of the performance measurement of the vertical ground-plane antenna ???? ???????? ???? used in the VSCS prototype at a distance of 3600 m still have a Signal Power Level at a value of -133.9 dBm or -163.9 dBW that meets the ICAO standard namely PBN SG/1-WP/4. The results of performance measurements on overall VoIP communication on this prototype have a delay below the maximum tolerance value of VoIP communication that is 100-150 ms. While jitter has a value below 50 ms that meets the maximum tolerance for streaming communication. Packet Loss on this prototype shows very good results at 0%, while the throughput has a varying value and this is greatly influenced by the intensity of speech and noise that enter at the time of measurement. Thus, the VSCS prototype that was built has a performance in accordance with the standards required by ICAO.
