<![CDATA[The face recognition process aims to identify some of the basic requirements of the system and learn the techniques required for the development of a realtime face recognition system. Facial recognition is one of the pattern recognition approaches for the purpose of identifying a person's face with a biometric approach. In this case Haar Feature is one of the methods to identify face recognition, Haar feature is used to recognize objects based on the simple value of a feature, not the pixel value contained in the object image. In testing this system, it is known that the success rate in the Confusion Matrix calculation on the image is between the actual and predicted values with a Precission value of 93%, meaning that the level of accuracy between the information requested by the user and the answer given by the system is the same. Recall results from the Precission value tend to be inverse to the results of the Recall value. If the Precission result is small then the Recall result is large, because the success rate of the Recall system in finding back a given information is 98%. Precission and Recall results are not the result of Accuracy. The difference is the level of closeness between the predicted results and the actual results of Precission and Recall. Where the actual results are the results found / relevant (True Positive) and the absence of true results / not found (True Negative) and these results are calculated based on the results found. The prediction results that users want, then the result of Accuarcy is 93% which is obtained based on the addition of actual results divided by the prediction results.]]>

<![CDATA[Palm oil is a very abundant source of vegetable oil and produces the highest vegetable oil compared to other plantation crops, which is the background of this research. This study aimed to classify the quality of CPO (Crude Palm Oil) into two classification classes using the Naïve Bayes method. This classification is expected to reduce human error in determining CPO quality. The parameters used in this research are free fatty acid content, moisture content and impurities which greatly affect the quality of CPO. By using the split data technique at the time of validation, the data is divided into training data and test data by 70:30. Based on the results of testing using the confusion matrix, the use of the Naïve Bayes method for data collected on research objects obtained an accuracy rate of 97.7% or included in the excellent category. While the specificity value is 95.8%, the recall value is 100%, and the precision is 95.4%.]]>

<![CDATA[Corn is one of the world's most popular carbohydrate-producing food crops, besides wheat and rice. The large number of corn plants attacked by pests and diseases can disrupt corn productivity and the community's economy because corn plants can be damaged, resulting in lower prices and quality of crops. This system aims to build an expert system to identify eight types of diseases and nine pests in corn plants from 49 symptoms using the Bayes Theorem method and make it easier for corn farmers to carry out control after knowing that there are identified pests and diseases. The Bayes Theorem method is a method for dealing with data uncertainty. This method is based on the initial conditions, which are the conditions of the existing symptoms, then subject to predetermined rules. Then the largest truth value is taken to determine conclusions and solutions to the previously mentioned symptoms. The results of 100% functionality have been successfully tested through black box testing. The results of the evaluation of the accuracy of the Bayes Theorem Method for identifying pests on corn plants amounted to 94.23%.]]>
