Tuberkulosis (TB) paru masih menjadi masalah kesehatan masyarakat di wilayah kerja Puskesmas Kuta Baro, Aceh Besar, dengan 27 kasus terkonfirmasi pada tahun 2024, sehingga diperlukan pemahaman komprehensif mengenai pengetahuan dan perilaku pencegahan pada individu kontak. Penelitian ini bertujuan menggambarkan tingkat pengetahuan dan perilaku pencegahan TB paru pada individu kontak dengan menggunakan desain deskriptif kuantitatif dan pendekatan potong lintang terhadap 140 responden yang dipilih melalui total sampling. Data dikumpulkan menggunakan kuesioner terstruktur dan dianalisis secara univariat dan bivariat menggunakan uji Chi-square. Hasil penelitian menunjukkan bahwa sebagian besar responden memiliki pengetahuan kurang baik (76,4%) dan perilaku pencegahan yang juga kurang optimal (61,4%). Terdapat hubungan bermakna antara lama serumah (p = 0,002) dan status imunisasi BCG (p = 0,037) dengan tingkat pengetahuan, sementara perilaku pencegahan hanya berhubungan dengan lama serumah (p = 0,004). Selain itu, ditemukan hubungan signifikan antara pengetahuan dan perilaku pencegahan (p = 0,000), di mana responden dengan pengetahuan rendah memiliki peluang 4,7 kali lebih besar untuk berperilaku kurang baik. Temuan ini menggarisbawahi perlunya penguatan edukasi kesehatan yang sistematis dan berkelanjutan guna meningkatkan pengetahuan serta perilaku pencegahan TB pada individu kontak dalam upaya memutus rantai penularan TB.

Pulmonary tuberculosis (TB) remains a public health concern in the working area of Puskesmas Kuta Baro, Aceh Besar, with 27 confirmed cases reported in 2024, highlighting the need for a comprehensive understanding of knowledge and preventive behaviors among close contacts. This study aimed to describe the level of knowledge and preventive behaviors regarding pulmonary TB among contact individuals using a quantitative descriptive design with a cross-sectional approach involving 140 respondents selected through total sampling. Data were collected using a structured questionnaire and analyzed using univariate and bivariate methods with the Chi-square test. The results showed that most respondents had poor knowledge (76.4%) and suboptimal preventive behaviors (61.4%). There was a significant association between length of cohabitation (p = 0.002) and BCG immunization status (p = 0.037) with knowledge level, while preventive behavior was significantly associated only with length of cohabitation (p = 0.004). Furthermore, a significant relationship was found between knowledge and preventive behavior (p = 0.000), with respondents who had poor knowledge being 4.7 times more likely to exhibit poor preventive practices. These findings underscore the importance of strengthening systematic and continuous health education to improve knowledge and preventive behaviors among contact individuals as an effort to interrupt TB transmission. Keywords: Pulmonary tuberculosis, knowledge, preventive behavior, contact with patients.
