Tuberculosis (TB) remains one of the main challenges in the health sector in Indonesia, with a fairly high number of cases each year. This study aims to analyze the distribution of TB cases based on occupation and identify community groups that are at higher risk of spreading this disease. The data used in this study were obtained from estimates of the 2022 TB epidemiology report. The results of the analysis show that informal workers, such as laborers and traders, are the group with the highest number of TB cases, at 36.0%. This is followed by formal workers (21.6%), farmers/fishermen (17.3%), housewives (14.4%), students (6.5%), and unemployed or retired groups (4.2%). The high prevalence of TB in informal workers is caused by several factors, including an unhygienic work environment, limited access to health services, and unhealthy lifestyles. Based on these findings, a more effective strategy is needed in efforts to prevent and control TB, especially for groups with high levels of vulnerability. Health education, increasing access to health services, improving work environment sanitation, and early detection programs are important steps in reducing the spread of TB. With the right intervention, it is hoped that the number of TB cases in Indonesia can be reduced significantly.

Mental health disorders, particularly depression, are becoming an increasing concern among university students. This study aims to analyze the comparative levels of depression among students from the 2022 and 2024 cohorts in the Biology Department at Universitas Negeri Medan. The research employs a mixed-method approach, integrating both quantitative and qualitative methodologies. Data were collected through questionnaires distributed to 51 active students. The results indicate that students from the 2022 cohort exhibit higher levels of depression compared to those from the 2024 cohort, due to academic pressure, social factors, and lifestyle habits. These findings highlight the importance of preventive strategies and interventions to mitigate depression risks, such as stress management, promoting healthy lifestyle habits, and strengthening social support in academic environments. Therefore, educational institutions must prioritize student mental health to foster a more conducive learning environment.
