Abstract

Perancangan jaringan komunikasi radio khusus memerlukan analisis propagasi untuk mengestimasi redaman sinyal (path loss) dan kualitas sinyal yang diterima. Kota Mataram sebagai wilayah studi memiliki karakteristik topografi dan lingkungan urban yang memengaruhi propagasi gelombang radio. Penelitian ini bertujuan untuk menganalisis dan membandingkan beberapa model propagasi, yaitu ITU-R P.1812-6, ITU-R P.1546-6, Longley-Rice (ITM), Okumura-Hata, serta ITU-R P.526 pada frekuensi 350–380 MHz. Simulasi dilakukan menggunakan software RadioPlanner dengan variasi tinggi antena 10 meter dan 30 meter. Parameter evaluasi meliputi Received Power, path loss, dan Signal-to-Noise Ratio (SNR), serta analisis regresi log-linear untuk memperoleh pathloss exponent. Hasil model Okumura-Hata menunjukkan Received Power sebesar –14,6 hingga 68,2 dBm (30 m) dan -96,9 hingga 25,4 dBm (10 m). Path loss berada pada rentang -9,59 –141 dB dan meningkat terhadap jarak, sedangkan SNR berkisar 31,3–196,23 dB.. Nilai pathloss exponent diperoleh sebesar 3,5–3,8 dengan koefisien determinasi 0.9 dan 1. Hasil menunjukkan peningkatan tinggi antena meningkatkan kualitas sinyal dan cakupan, serta model Okumura-Hata cukup representatif untuk lingkungan urban.

The design of specialised radio communication networks requires propagation analysis to estimate signal attenuation (path loss) and the quality of the received signal. The city of Mataram, as the study area, has topographical and urban environmental characteristics that influence radio wave propagation. This study aims to analyse and compare several propagation models, namely ITU-R P.1812-6, ITU-R P.1546-6, Longley-Rice (ITM), Okumura-Hata, and ITU-R P.526 at frequencies of 350–380 MHz. Simulations were carried out using RadioPlanner software with antenna heights of 10 metres and 30 metres. The evaluation parameters included Received Power, path loss, and Signal-to-Noise Ratio (SNR), as well as log-linear regression analysis to determine the path loss exponent. The results of the Okumura-Hata model showed Received Power ranging from –14.6 to 68.2 dBm (30 m) and from –96.9 to 25.4 dBm (10 m). Path loss ranges from –9.59 to –141 dB and increases with distance, whilst SNR ranges from 31.3 to 196.23 dB. The path loss exponent values obtained were 3.5–3.8 with a coefficient of determination of 0.9 and 1. The results indicate that increasing antenna height improves signal quality and coverage, and that the Okumura-Hata model is sufficiently representative for urban environments.
