Abstract

Rainfall is a very crucial weather parameter. The information on rainfall is also used for certain fields including farming, transportation, and flood early warning system. The significant fluctuation of rainfall in Bandung recently causes the difficulty in rainfall forecasting. The study analyzes and implements Soft Computing algorithm for rainfall forecasting in Bandung Regency. The algorithms belong to SC method are Fuzzy Logic, Neural Network, and Evolutionary Algorithms (EAs). The study compares the performance of the forecasting from two algorithms, Grammatical Evolution (GE) and Adaptive Neuro-Fuzzy Inference System (ANFIS). For GE algorithm, the comparison between two survivor selection methods is conducted, namely between generational replacement and steady state. The experiment used the rainfall data for Bandung regency obtained from Indonesian Agency for Meteorology Climatology and Geophysics (BMKG) for the current 10 years (2003-2012). The experiment shows the performance of forecasting result of 70.76% for GE that uses the generational replacement, 74.35% for GE that uses the steady state and 80% for ANFIS.
