Tuberculosis (TB) is a contagious disease of the respiratory system that remains a global public health problem, including in Indonesia, with high incidence rates among adolescents due to intense social activities and interactions. This community service activity aims to increase adolescents' knowledge about TB from an epidemiological perspective, including modes of transmission, symptoms, risk factors, and prevention efforts as an airborne disease. The method used was a quasi-experimental approach with a two-group pretest-posttest design, through health education provided to 149 adolescents aged 15–17 years at Darussalam High School in Medan. Data collection was conducted using questionnaires to assess the level of knowledge before and after the educational intervention. The results of the activity showed a significant increase in the level of knowledge after the education was provided, where the percentage of respondents in the high knowledge category increased from 82% in the pre-test to 93% in the post-test, accompanied by a decrease in the sufficient and low knowledge categories. This study shows that community service activities through health education have a significant effect on increasing adolescents' knowledge about tuberculosis. Health education has been proven to be effective as a promotional and preventive measure, so it needs to be implemented continuously to prevent the transmission

Tuberculosis (TB) is an infectious disease that remains a public health problem in Indonesia, including in Banjarmasin City. Low public knowledge and awareness of clean and healthy living behaviors (PHBS) are also factors in the high rate of TB transmission. Health education is a strategic step in addressing this problem. This study aims to determine the effect of health education using lecture methods and audio-visual media on increasing knowledge in TB prevention efforts in the Alalak Tengah Community Health Center working area. The research design used was a pre-experimental study with a one-group pre-test post-test design approach. The study sample consisted of 51 respondents selected by purposive sampling. The research instrument was a questionnaire administered before and after the education, then analyzed using the Wilcoxon test. The results showed a significant increase in knowledge after the education intervention (p value <0.05). Before the education, most respondents were in the sufficient and poor knowledge categories, while after the education, most respondents moved to the good knowledge category. This indicates that the combination of lecture methods and audio-visual media can effectively increase public understanding. Delivering information through visualization has proven to be more engaging and easier to understand for a wide range of audiences. The conclusion of this study is that this outreach method is effective as a medium for educating the public about TB prevention. A similar approach can be implemented more widely in other regions to support the national TB control program. Consistent and sustainable education programs are essential to maintain high levels of public knowledge. The involvement of health workers, cadres, and community leaders is also a crucial factor in the success of outreach. This strategy is expected to be replicated in other regions with a high TB ​​burden.

Tuberculosis (TB) is a contagious illness triggered by Mycobacterium tuberculosis, with transmission influenced by not only personal behaviors but also by the physical condition of the home environment. Environmental risk factors include flooring, wall material, ceiling structure, indoor temperature, humidity levels, air ventilation, habits of opening windows, and housing density. This research aimed to explore the correlation between individual behavior and the quality of home environmental conditions with pulmonary TB incidence in the Sematang Borang Health Center’s coverage area, Palembang, in 2025. A descriptive observational design was employed, involving 91 participants from Lebung Gajah Subdistrict. The sample consisted of both confirmed pulmonary TB patients (PCR positive) and individuals without TB (PCR negative), selected through purposive sampling. Data were processed using univariate analysis to describe frequency distributions and respondent characteristics. The study found that 35.2% of respondents were diagnosed with pulmonary TB, while 64.8% were not. Most participants were between 46 and 65 years old (42.9%), predominantly female (59.3%), and had a senior high school education (40.7%). In terms of TB-related knowledge and behavior, 59.3% had good knowledge, 63.7% held a positive attitude, and 50.5% practiced proper prevention measures. Nevertheless, more than half (56.0%) of the housing conditions failed to meet health standards for a safe home environment. These findings highlight that while the community shows generally good awareness and preventive behavior regarding TB, many still reside in environments that may contribute to TB transmission. Therefore, continuous health education, proactive contact tracing, and targeted health campaigns for at-risk groups—especially among those with lower educational backgrounds—should be prioritized.

Tuberculosis (TB) is an infectious disease caused by infection with bacteria from the Mycobacterium tuberculosis complex group. TB prevention efforts are crucial, especially for individuals at high risk of exposure, to disrupt the chain of transmission of this disease. The intervention aimed to increase community understanding of TOSS TB (Find, Treat, Treat Until Cured) so that it can be applied in daily life. It is expected that after the intervention, participants' knowledge will increase, as will their ability to demonstrate the practices taught appropriately. Data collection was conducted through a mini-survey of the community in the local Community Health Center (Puskesmas) working area. The data obtained were then analyzed using the Blum Paradigm to identify factors contributing to the problem. Problem prioritization was carried out using the non-scoring Delphi method, while root cause analysis was conducted using a fishbone diagram. During the intervention process, pre- and post-tests were conducted to evaluate changes in the level of knowledge of villagers before and after the intervention. For program monitoring and evaluation, the PDCA (Plan-Do-Check-Act) cycle approach and a systems approach were used. The analysis using the Blum Paradigm showed that lifestyle was the primary contributing factor to the problem. After the intervention, three participants were able to repeat the material effectively, demonstrating a better understanding of TB prevention. Based on these results, it can be concluded that the intervention was successful and is expected to encourage improvements in public health in the village. Furthermore, this program is also expected to serve as a model for other public health interventions, thereby expanding the positive impact of TB control efforts in other areas. Thus, public awareness and knowledge about TB can continue to increase, which in turn will contribute to reducing TB incidence in Indonesia and improving the overall quality of life of the community.

Tuberculosis (TB) is one of the ten diseases that most frequently causes death worldwide. This disease is caused by Mycobacterium tuberculosis and lasts a long time. Indonesia ranks third in the world in terms of the number of people suffering from tuberculosis, behind India, China and India. In East Nusa Tenggara, the most cases of tuberculosis are found in Kupang City, and Oesapa Village is one of the places where cases are still quite high. With so many TB cases still occurring, public knowledge about the symptoms, transmission and treatment of the disease is still lacking. It is hoped that empowering teenagers as health drivers will increase public awareness, especially teenagers, about prevention, symptom monitoring, and discovery and treatment of tuberculosis. Tuberculosis education can help teenagers understand the importance of maintaining a clean and healthy lifestyle to reduce TB transmission (1). This community service activity aims to increase youth knowledge and attitudes about pulmonary TB through comprehensive counseling, structured information, and youth empowerment. They also monitor communities for TB symptoms, especially children(2) The results of the activity show that the level of understanding among teenagers about TB disease has increased from 35 percent to 85 percent. There were no TB symptoms at the monitoring stage in the community, especially teenagers, and everyone was in good health. It is hoped that peer cadres (adolescents) can adopt a clean and healthy lifestyle and become pioneers in monitoring the symptoms of tuberculosis in the community to make it easier to find, handle and treat. Peer cadres can transfer information about pulmonary TB to the community, especially teenagers, by implementing Clean and Healthy Living Behavior

Mycobacterium tuberculosis is a bacterium that causes the infectious disease pulmonary tuberculosis (TB). Bayongong District is ranked second in terms of TB cases found in Garut Regency. The involvement of adolescents in controlling TB disease is needed as an agent of change to increase early detection of TB in their family members. With early detection of TB disease, treatment can be started quickly and transmission can be controlled. To increase teenagers' knowledge and awareness of TB disease, it is necessary to provide education to teenagers, namely high school students in Bayongbong District, about the importance of recognizing symptoms, transmission, prevention and treatment, as well as laboratory examinations for TB disease. Education is carried out by presenting material related to TB disease. Apart from that, students were also shown a video on how to carry out a TB examination using BTA (Acid Fast Bacteria) staining and TCM (Rapid Molecular Test). Before and after education, each student received a questionnaire designed to measure their level of knowledge. After community service, education about TB disease among high school students resulted in an increased understanding of TB symptoms, transmission, prevention, treatment and examination.
