Abstract

Cement is an important material in the development process. Cement production in Indonesia is quite high compared to the amount of consumption. This condition results in oversupply, a condition where the amount of production is greater than the amount of consumption. This resulted in falling cement prices and warehouse full of cement that has not been sold. This makes the Indonesian Cement Association (ASI) to issue its regulation to temporary stop producting cement. This study aims to predict the amount of cement demand in the next time so that regulations can be issued more quickly, so the factory can adjust its production capacity without having to stop production. Many methods can be used to make predictions, for example is Backpropagation Neural Network which is proven to provide good results in predicting, such as predicting the amount of newspaper demand and sugar production. This research uses Backpropagation Neural Network with network architecture of 6 input neurons, 4 hidden neurons and 1 output neuron. The best parameters used are the learning rate of 0.8, the maximum iteration of 200 and the initial weight interval between -1,4 to 1,4. The MSE best predictive value is 0.049064.

Abstract

Red chili is one of the most important vegetables in Indonesia, whether it is as a commodity that is consumed domestically and as an export commodity. As vegetables, beside red chili has a high nutritional value, it also has a high economic value. However, the productivity of national red chilli is still very low at 7.34 tons / ha, whereas the actual yield can potentially reach 12 tons / ha. In a planting period, chili can be harvested several times. If the season and the treatment is very good, chili can be harvested 15-17 times but generally, it can be harvested only 10-12 times. The low productivity of chili can be caused by a variety of factors, including poor quality of chili seeds, decreasing soil fertility, bad implementation of cultivation techniques, plant pest and disease problems. In order to handle this, technology is needed by applying one of the classification methods, namely Modified K-Nearest Neighbor (MKNN). Modified K-Nearest Neighbor (MKNN) is the development of the KNN method that has been designed to overcome the weaknesses of the distance between data and weight in the KNN. The method analysis is based on 18 symptoms of the disease with the process of calculating euclidean distance, calculating the validity and calculation of wighted voting which result in the determination of the classification class based on the specified K value. The test results showed that when using the value K = 5 produces an accuracy of 94%, then K = 8 produces an accuracy of 92%, K = 11 produces an accuracy of 88% and testing K = 14 produces an accuracy of 88%. Based on the results obtained, the Modified K-Nearest Neighbor (MKNN) method showed good accuracy for classifying chili disease.
