Abstract

Sistem komunikasi HF merupakan sistem komunikasi yang mempunyai range frekuensi dari 3-30 MHz dengan panjang gelombangnya sekitar 10-100 m. HF berguna untuk komunikasi jarak jauh dengan jarak komunikasinya sekitar 150 sampai ribuan km di seluruh dunia dengan memanfaatkan lapisan ionosfer untuk memantulkan gelombang menuju belahan bumi tanpa menggunakan relay satelit, serta mengantisipasi efek dari bencana alam agar komunikasi tetap berjalan di kawasan bencana tersebut. Kualitas informasi yang diterima berperan penting dalam berkelanjutannya informasi tersebut. Sistem komunikasi HF dengan menggunakan metode SIMO 1x2 dengan skema MRC bertujuan untuk meningkatkan kualitas informasi yang akan diterima terutama pada kawasan bencana. Teknologi HF SIMO dengan skema MRC ini menjadi salah satu sistem komunikasi alternatif untuk mengatasi daerah yang rawan bencana alam. Pada sisi pemancar dan penerima, masing-masing memiliki 1 antena dan 2 antena untuk metode Single Input Multi Output (SIMO) pada link Bandung-Surabaya dan Surabaya-Malang. Proses evaluasi kinerja sistem komunikasi HF dengan skema MRC dapat memperhitungkan parameter SNR dan BER untuk mengetahui seberapa besar kualitas informasi yang diterima. Dan, didapatkan bahwa peningkatan SNR sebesar 6,7-8,7 dB dan penurunan BER sebesar 3,1-3,2 kali lipat penurunan. ================ HF communication system is a communication system that has a frequency range from 3-30 MHz with a wavelength of about 10-100 m. HF is useful for long distance communications with communications spacing of about 150 to thousands of km worldwide using the ionosphere to reflect waves to the hemisphere without the use of satellite relays, as well as the impact of these natural disasters in order to continue working in that affected area. Complete information that contains important information in its sustainability. HF communication system using SIMO 1x2 method with MRC theme serves to improve the quality of information that will be received specially in disaster area. HF SIMO technology with this MRC arrangement becomes one of alternative communication system to overcome disaster-prone areas. On the transmitter and receiver sides, each have 1 antenna and 2 antennas for Single Input Multi Output (SIMO) method at link of Bandung - Surabaya and Surabaya - Malang. HF with MRC method can calculate SNR and BER parameter to know much information received. And, it was found that the increase of SNR by 6,7 until 8,7 dB and decrease of BER by 3,1 until 3,2
