Penerapan Teknologi/Mage Processing dan Artificial Neural Network untuk Menduga Ketersediaan Air dan Nutrisi pada Pertumbuhan Tanaman Cabal Merah

Abstract

The objective of this research is to predict the water and nutrient status during the growth of red chili plant by means of an image processing and artificial neural network algorithm. In this study, about 150 chili plants were cultivated at Leuwi Kopo's Greenhouse but only 30 plants were chosen as samples. The data were collected using a CCO Camera only during the vegetative growth and the collected data were analyzed using a back propagation artificial neural network. The results showed the linear relationship between the predicted and target values of water with a coefficient determination of 0.728 and 0.973 for the training and validation data, respectively. The linear relationships were also found between the predicted and target values of nutrient with a coefficient determination of 0.716 and 0.963 for the training and validation data, respectively. Key word: Red chilli plant, image processing, artificial neural network, water and nutrient status.
