ANALISIS KINERJA JARINGAN VSAT BERBASIS SCPC MENGGUNAKAN PARAMETER QUALITY OF SERVICE // PERFORMANCE ANALYSIS OF A SINGLE CHANNEL PER CARRIER (SCPC)-BASED VERY SMALL APERTURE TERMINAL (VSAT) NETWORK USING QUALITY OF SERVICE PARAMETERS

Sistem komunikasi berbasis Very Small Aperture Terminal (VSAT) memiliki peran
penting dalam mendukung pengiriman data pada wilayah yang membutuhkan
jangkauan komunikasi luas. Namun, jaringan VSAT memiliki karakteristik delay
yang relatif tinggi karena proses transmisi sinyal dilakukan melalui satelit. Oleh
karena itu, diperlukan analisis kinerja jaringan untuk mengetahui kualitas layanan
yang dihasilkan . Penelitian ini bertujuan untuk menganalisis kinerja jaringan VSAT
menggunakan parameter Quality of Service (QoS), yaitu delay, throughput, packet
loss, dan jitter. Metode yang digunakan dalam penelitian ini adalah metode
kuantitatif deskriptif dengan data pengukuran jaringan yang telah terdokumentasi.
Data yang dianalisis meliputi nilai download, upload, ping, jitter, dan packet loss.
Penguolahan data dilakukan dengan menghitung nilai rata-rata, nilai minimum, dan
nilai maksimum, kemudian hasilnya dibandingkan dengan standar TIPHON. Hasil
penelitian menunjukkan bahwa nilai rata-rat delay sebesar 918 ms dan termasuk
kategori jelek. Throughput download memperoleh rata-rata sebesar 4,97 Mbps atau
82,83% dari kapasistas layanan download, sedangkan troughput upload memperoleh
rata-rata sebesar 0,95 Mbps atau 47,50% dari kapasitas layanan upload. Nilai ratarata packet loss sebesar 4.47% dan termasuk kategori sedang, sedangkan nilai ratarata jitter sebesar 383,17 ms dan termasuk kategori jelek. Berdasarkan hasil tersebut,
jaringan VSAT masih dapat digunakan untuk layanan komunikasi data, namun
kualitas jaringan belum optimal pada aspek delay dan jitter. // Very Small Aperture Terminal (VSAT)-based communication systems play an
important role in supporting data transmission in areas that require wide
communication coverage. However, VSAT networks have relatively high delay
characteristics because signal transmission is carried out through satellites.
Therefore, network performance analysis is required to determine the quality of
service provided. This study aims to analyzed the performance of a VSAT network
using Quality of Service (QoS) parameters, including delay, throughput, packet loss,
and jitter. The method used in this research is a descriptive quantitative method using
documented network measurement data. The analyzed data include download, upload,
ping, jitter, and packet loss values. Data processing was carried out by calculating the
average, minimum, and maximum values, then comparing the results with the TIPHON
standard. The results show that the average delay value is 918 ms and is classified as
poor. The average download throughput is 4.97 Mbps, or 82.83% of the download
service capacity, while the average upload throughput is 0.95 Mbps, or 47.50% of the
upload service capacity. The average packet loss value is 4.47% and is classified as
medium, while the average jitter value is 383.17 ms and is classified as poor. Based
on these results, the VSAT network can still be used for data communication services;
however, the network quality is not yet optimal, particularly in terms of delay and
jitter.
