The bacterium Mycobacterium tuberculosis is the cause of this disease. Patients suffering from this disease must be treated quickly. Currently, patients need a long time and a large cost in detecting the bacteria that cause this disease. The technique used is to take the patient’s lung fluid by biopsy and given Ziehl Neelsen chemical dye and then observed using a microscope. This study aims to help detect bacteria quickly and precisely by processing the image produced by the microscope. The technique used is to develop the segmentation method. The segmentation process carried out is to develop a Hue Saturation Value (HSV) color space transformation technique with Active Contour, Edge Detection, and Otsu techniques. The images used in this research are 51 images taken from H. Adam Malik Hospital, Medan and have been validated by an expert. Of the several segmentation methods used in this study, the maximum or best result in detecting Tuberculosis Extra Pulmonary (TBEP) bacilli is the Otsu method. So the method developed is very helpful in accelerating the detection of TBEP. Description: Tuberculosis (TB) is a chronic and infectious disease that affects the world’s human population and requires complex treatment [1], Tuberculosis, with an estimated 10 million cases and 1.3 million deaths annually, continues to be a global health priority [2], The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease pandemic 2019 (COVID-19) requires concerted public health focus and action due to its rapid global spread, clinical severity, high mortality rate with 4 million deaths, and capacity for the health care system. The impact of COVID-19 on TB services has been explained by the reduction in the number of TB cases diagnosed and managed in most countries. Conservative models suggest that a 20% increase in TB deaths in the next 5 years is likely as a result of the pandemic [3]. Tuberculosis (TB) is a life-threatening infectious disease worldwide caused by the bacterium Mycobacterium tuberculosis. These bacteria are in the form of acid-fast bacilli or often called acid-fast bacilli (BTA). These bacilli are 1-4 m long and 0.3-0.56 m wide, non-sporing, non-motile, and facultative. Bacterial cell walls contain long-chain mycolic glycolipids, rich in acids and phosphopoglycans [4–6]. Tuberculosis can attack every human being. Those of productive age are susceptible to tuberculosis between the ages of 15 and 50 years and children. Tuberculosis bacteria usually come out through phlegm and cough, if the saliva is at a low temperature, then the possibility for germs to survive will be long enough to allow the transmission process. There are 2 types of Tuberculosis, namely Pulmonary Tuberculosis (TBP) and Tuberculosis Extra Pulmonary (TBEP). TBP affects the lungs, whereas TBEP can affect any organ of the body except the spine, heart, pancreas, skeletal muscle, and thyroid [7–9]. Figure 1 below shows the Mycobacterium Tuberculosis bacilli. Mon, 03 Oct 2022 00:00:00 GMT http://repository.potensi-utama.ac.id/jspui/jspui/handle/123456789/5523 2022-10-03T00:00:00Z
