Artificial Neural Network (ANN) techniques were used to develop and validate water quality by predicting the Water Quality
Index (WQI) in Melaka River Basin, Malaysia. Nine sampling stations were monitored in total. ANN techniques were applied
for testing and developing the water quality prediction based on two sets of data. In the first data set, the independent water
quality of six variables was used as input into ANN for trained, test and validated samples. In the second data set, a combination
between Multiple Linear Regression (MLR) and ANN indicating only Chemical Oxygen Demand (COD), Biochemical Oxygen
Demand (BOD), Suspended Solid (SS), and Ammoniacal-Nitrogen (AN) are accounted for training, testing and validating in
modeling the water quality. Generally, MLR is used to exclude the lowest value invariance of independent variables, while
rejecting the Dissolved Oxygen (DO) and pH. Based on the result of the correlation coefficient, the second set data (0.89) is
marginally better than the first set data (0.87). These circumstances stated that predictions for WQI using ANN are acceptable,
and the result is better when the variables of DO and pH are eliminated. |
