| Summary: | Microbial population and species during spontaneous fermentation process of Carica Papaya leaf was unpredictable. Therefore, the Artificial Neural Networks (ANNs) method was used in this research because of the non-linearity pattern of the experimental data obtain. The parameter involve are the day of fermentation (1-100) days and the volume of water sample used (5L and 50L) as the input. The suitable of transfer function were used which are Levenberg Marquardt (trainlm) as training function and hyperbolic tangent sigmoid (tansig) as activation function to get the best performance model. The number of hidden layers to use was maximize into two hidden layers (multiple hidden layer) and the number of neurons was specified as seven neurons where can achieved the optimum model with using of the feedforward algorithm. The parameter of the output layer as the experiment data was the microbial population and the species of the C. Papaya leaf. Lastly, determining the best performance model were referring to their lower relative error percentage with correlation coefficient (R value) approach to one (1) and the least number of Mean Square Error (MSE). |
