Based on this, the purpose of this study is to apply a Deep Learning work model using the Convolutional Neural Networks method to recognize faces using masks. To test the accuracy of CNN, the CNN model used there are 4 models, 3 models made by yourself, and 1 model using Transfer Learning VGG16, the data used in the study amounted to 30 faces with each face added a digital mask. Augmentation was carried out to increase the data in the training process, then tested on 30 faces using original masks, video testing was also carried out to test the performance of the CNN model in recognizing moving faces. In this study, the test resulted in decreased accuracy between 5 to 30%.} }
