One health disorder that is categorized as a serious disease and can cause death is an inflamed lung condition, which is then called pneumonia. Each year, pneumonia infects about 450 million people (about 7% of the worlds total population) and causes about 4 million deaths. The World Health Organization (WHO) in 2020 reported that this disease is the cause of 15% of deaths in children under 5 years old. In Indonesia, based on a report from the Indonesian Ministry of Health in 2018, the number of people experiencing health problems due to pneumonia is around 2%. The Covid-19 pandemic that has occurred since the beginning of 2020 has worsened this condition massively. The SARS-CoV-2 Corona Virus, which causes Covid-19, attacks the respiratory tract and infects the lungs, which then causes the lungs to become inflamed. Pneumonia due to COVID-19 is then known as Covid-19 Pneumonia. This research aims to detect COVID-19 pneumonia based on digital images obtained from the acquisition of lung objects from X-rays / x-rays of the lungs. The experimental process is carried out to classify the image of the lungs in normal conditions (no inflammation), experiencing inflammation due to the SARS-CoV-2 corona virus (covid-19 Pneumonia), or experiencing inflammation due to other factors (pneumonia). The classification approach used is the Convolutional Neural Network (CNN) method which uses a 5-layer convolution architecture with filter values of 16, 32, 64, 128, and 256. The experimental process uses 3900 images for the training process, 450 images for the validation process, and 225 images for the testing process. Based on the testing process that has been carried out, the performance of the Covid-19 Pneumonia classification resulted in an accuracy of 84.88%, a precision of 0.85, a recall of 0.84, and an f1 score of 0.85.
