Abstract


Paddy (oryza sativa) was a basic foodstuff that was vital for people of Indonesia. The amount of rice production at a time can not be calculated exactly, so it was necessary to predict rice production in order to provided rice to achieve endurance and food self-sufficiency. This research aimed to make prediction system of rice production in january-april  period, may-august period, and september-december period using interval regression with neuro fuzzy in Kubu Raya regency. The interval regression method was based on backpropagation network which there are two separately trained backproagation networks, one model to find out the lower bound and one model to find out the upper bound. Based on the results of the training and testing phase, the best network result were obtained by 4 input layer neurons, 3 hidden layer neurons and 1 output layer neuron using minimum error parameter 0,00001 and maximum epoch 100000. The results showed that MSE BPN- for period 1 training with lr 0.09 of 0,064722 and MSE BPN+ of 0,030644; Period 2 with Ir 0.09 results of MSE BPN- 0,141674 and MSE BPN+ of 0,179612, and period 3 with Ir 0.09 results of MSE BPN- of 0,025324 and MSE BPN+ of 0,036961. The mean deviation of the interval between the lower limit with the actual value on the test data was 4.369,2 (BPN-), while the interval deviation between the upper limit with the actual value on the test data was 19.744,3 (BPN+).
