Abstract

Kisaran frekuensi radio komersil dan frekuensi penerbangan berdekatan sehingga berpotensi untuk terganggu. Kondisi tersebut bisa membahayakan keselamatan penerbangan karena tidak jelasnya informasi yang diterima oleh pilot. Tujuan penelitian ini mengkaji potensi gangguan frekuensi pemancar radio terhadap frekuensi penerbangan, menggunakan metoda simulasi. Gangguan dilihat dari nilai Voltage Standing Wave Ratio (VSWR) yang terjadi pada hasil simulasi sehingga dapat mengidentifikasi apakah pengguna radio frekuensi sesuai dengan aturan yang ditetapkan. Informasi dari simulasi juga dapat mengetahui mode dari modulasinya sehingga diketahui jenis intermodulasi dan pemancar-pemancar radio penyebabnya. Dari hasil simulasi dengan menggunakan VSWR ini juga dapat disimpulkan bahwa stasiun radio yang beroperasi perangkatnya sudah memenuhi standar dan harus senantiasa diperiksa kondisi perangkatnya untuk menjaga linearitas jaringannya agar emisi tersebar (spourius emission) yang terdiri dari harmonisa, intermodulasi, parasitik dapat dikendalikan level dayanya. Untuk mengatasi gangguan frekuensi radio, disarankan menggunakan peralatan berupa low pass filter untuk meminimalkan besarnya level frekuensi intermodulasi sehingga tidak mengganggu frekuensi existingnya.
