ABSTRAK

Pada era globalisasi saat ini teknologi telekomunikasi berkembang dengan sangat pesat. Begitu juga dalam bidang broadcasting penyiaran. Sehingga sangat memungkinkan meningkatnya kebutuhan terhadap kanal frekuensi yang baru. Pada penelitian ini digunakan data pengukuran level daya pada link propagasi dari Banda Aceh ke Surabaya yang berjarak 2400 Km jarak jauh dengan menggunakan frekuensi izin ORARI yaitu 14.3 MHz. Pemodelan yang digunakan yaitu dengan pemodelan ARIMA sehingga perlu dipertimbangkan sifat tak stasioner dalam dimensi waktu agar didapat keakuratan yang tinggi. Dari hasil pemodelan diperoleh dua belas model ARIMA yaitu Model ARIMA 011 100 101 102 103 104 005 200 201 202 205 dan 303. Model ARIMA yang paling dominan yaitu model ARIMA 102 dengan jumlah event 3067 model ARIMA 202 dengan jumlah event 20 model ARIMA 201 1467 model ARIMA 103 933 model ARIMA 101 667 ARIMA 303 533 model ARIMA 011 4 ARIMA 100 4 model ARIMA 005 200 205 dan 104 masing-masing 133. Dari kedua belas model tersebut hanya dua model yang paling mendekati dengan model pembangkitan yaitu model ARIMA 100 dan model ARIMA 102. Dari seluruh model ARIMA yang diperoleh dipilih salah satu model ARIMA terbaik dengan mempertimbangkan kriteria AIC dan MSE yang paling kecil Model ARIMA terbaik tersebut adalah model ARIMA 102.


ABSTRACT

In the current era of globalization telecommunication technology develops very rapidly. As also in the broadcasting field. So it is possible increasing the need for new frequency channel. This study used the data on the power level measurements at the propagation link from Banda Aceh to Surabaya within 2400 km long distance using 14.3 MHz ORARI permission frequency. The Modeling used is ARIMA modeling so should be considered the unstationary nature of the time dimension in order to obtain high accuracy. The modeling results obtained twelve ARIMA model is ARIMA model 011 100 101 102 103 104 005 201 202 200 205 and 303. The most dominant ARIMA models is ARIMA model 102 with a number of events as much as 30.67 ARIMA 202 with the number of events by 20 the model ARIMA 201 is as much as 14.67 ARIMA 103 of 9.33 the model ARIMA 101 6.67 ARIMA 303 of 5.33 the model ARIMA 011 4 ARIMA 100 4 005 200 205 and 104 respectively by 1.33. And only two models that most closely to the generation model are ARIMA model100 and ARIMA model 102. Of all ARIMA model obtained are selected one of the best ARIMA modelwith considering the AIC criteria and the smallest MSE. Best ARIMA model is ARIMA 102.
