Pulmonary tuberculosis is an infectious disease caused by Mycobacterium tuberculosis which mostly attacks the lungs and can also attack other organs. Tuberculosis is transmitted by smear positive tuberculosis patients, Tuberculosis germs are transmitted through the air when the patient coughs and sneezes so that the germs spread in the air in the form of droplets (sputum sparks), so people can become infected if they inhale the droplet into the respiratory tract (Ministry of Health Republic of Indonesia, 2014 ). According to Achmadi (2010) risk factors for tuberculosis transmission are environmental and behavioral factors. Environmental factors include ventilation, occupancy density, temperature, lighting and humidity. Whereas behavioral factors include smoking, spitting or sputum in any place, coughing or sneezing not closing the mouth and habit of not opening the window. Based on the results of a survey in Indonesia by the Directorate General of Communicable Disease Eradication and Environmental Health (2011), the high incidence of pulmonary TB is caused by a lack of knowledge. Knowledge of tuberculosis sufferers will affect the attitude and behavior such as throwing up spit or sputum that can be carelessly a source of transmission for people around him. Prabu in Fitriani (2013) explained that family heads who have an income below the regional minimum wage (UMR) will consume foods with nutrient levels that are not in accordance with the needs of each family member so that they have an nutritional status that is lacking and will make it easier to contract infectious diseases including Lung TB. According to WHO the number of cases of tuberculosis is ranked above HIV / AIDS. In 2016 there were an estimated 10.4 million new cases of tuberculosis or 142 cases / 100,000 population, 60% of new cases occurred in 6 (six) countries namely India, Indonesia, China, Nigeria, Pakistan and South Africa, and Indonesia ranked second (WHO Global Tuberculosis Report, 2017). Based on data on Indonesia's health profile in 2018 the number of tuberculosis cases in Indonesia in 2017 was 420,994 cases and increased in 2018 to reach 511,873 cases (Ministry of Health Republic of Indonesia, 2018). The number of pulmonary tuberculosis in Riau Province in 2018 is 11,135 cases (Ministry of Health of the Republic of Indonesia, 2018). Based on data on the health profile of Kampar Regency in 2017, tuberculosis is an environmentally-based direct infectious disease that ranks second with a total of 1,071 cases after diarrheal disease with a total of 1,076 cases. The number of positive AFB cases in 2017 in Kampar District reached 1071 cases, with the highest number of sufferers found in Tambang District, 78 cases.
