... Pneumonia. This study uses a lung X-ray image dataset. In this study there are 4 folders in it, namely Scenario 1, Scenario 2, Scenario 3, and Scenario 4. This study will use the Convolutional Neural Network (CNN) method by using an architectural model including Convolutional 2D, activation layers, max pooling layer, dropout layer , flatten, and finally dense layer. After building the model, in each scenario, the results of accuracy, precision, recall, and f1-score will be obtained. The result of accuracy of Scenario 1 is 97.87%, in Scenario 2 the accuracy is 94.84%, in Scenario 3 is 91.66%, and Scenario 4 is 91.41%.
