UT-AKSES NETWORK PERFORMANCE AND RELIABILITY IN SUPPORTING DISTANCE EDUCATION

Abstract

Universitas Terbuka (UT), as a pioneer of distance education in Indonesia, has developed the UT-Akses Point (UT-AP) system to support inclusive and flexible online learning. This study aims to evaluate the performance and reliability of the UT-Akses network in supporting the distance learning process. UT-Akses uses a low-orbit (LEO) satellite constellation capable of reaching remote areas, including the 3T (outermost, disadvantaged, and isolated) areas, which have previously been difficult to reach by terrestrial networks. The methods used include literature studies, secondary data analysis, and observations of the implementation of learning technology at UT. The results of the study indicate that UT-Akses has high performance in terms of service coverage, access flexibility, and digital technology integration through a digital learning ecosystem (Digital Learning Ecosystem). However, satellite signals are susceptible to atmospheric interference and physical obstacles such as obstruction by buildings, geographical location with many tall trees that obstruct the placement of equipment. To measure the reliability of UT-Akses, parameters are used, including: Average download throughput, Maximum download throughput, Average upload throughput, Maximum upload throughput, Percentage of time latency is below 90ms, Percentage of time latency is below 50ms, Down time, Average power consumption, and Peak power consumption. The UT-Akses trial program in 2025 was carried out at 20 blank spot locations including UT Kupang, UT Menado, UT Pontianak, UT Palangkaraya, UT Jambi and UT Bengkulu.
