Abstract

Prediksi Curah Hujan Bulanan di daerah Purbalingga telah dilakukan menggunakan metode Kalman Filter dengan Prediktor SST 3.4. Validasi terhadap prediksi tiga tahun kebelakang (hindcast) 2006, 2007, 2008 menunjukkan nilai koefisien korelasi mencapai 75%. Untuk memperoleh nilai prediktor SST Nino 3.4 diprediksi menggunakan metode ARIMA. Validasi prediksi SST Nino 3.4 selama tiga tahun periode pengujian menunjukkan pada tahun 2006 r=0.91, 2007 r=0.64 dan 2008 r=0.82. Monthly Rainfall Prediction in the area Purbalingga been performed using the method of Kalman Filter with SST Predictor 3.4. Validation of predictions three years before (hindcast) 2006, 2007, 2008 showing the correlation coefficient reached 75%. To obtain Nino 3.4 SST predictor values predicted using ARIMA method. Validation of Nino 3.4 SST predictions for three-year testing period in 2006 showed r = 0.91, 2007 and 2008, r = 0.64 r = 0.82
