Implementasi R Software Untuk Prediksi Curah Hujan (Perbandingan ARMA dan ARIMA)

Abstract

Rainfall or weather conditions that occur in a particular area can basically be calculated, or
predicted. X district is an area that is frequently flooded during the rainy season. Forecasting rainfall can
help governments and communities in taking flood precautions [1]. In this study, forecasting rainfall in
the district of X, is done by using time series method approach. To perform forecasting rainfall, used two
methods, ARMA and ARIMA. Furthermore, the results of both methods are compared with the actual data
to determine which method is most closely with real data. The conclusion of this study is the method of
ARMA (1,1) forecasting results are closer to the real data [2].
