Perilaku dan Kualitas Kesehatan Lingkungan Fisik Rumah dengan Kejadian Penyakit TB Paru di Kota Palembang

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.
