Moreover, ensuring treatment adherence is crucial for pulmonary TB patients, as it improves positive treatment outcomes and prevents drug resistance. To enhance health literacy, self-efficacy, and treatment adherence, the current use of digital media offers a distinct opportunity for disseminating information. Therefore, this research aimed to develop EduTB as an online health information application to enhance knowledge and adherence to TB treatment. The design of EduTB included the combination of the PRECEDE-PROCEED and MATCH models, serving as a health promotion model starting with the analysis stage. This was followed by designing a TB health education model, namely Partnership Online Learning (POL). In the design stage, the model and educational product have been developed. The supporting products for the education model and testing instruments for development include validity and practicality testing on small and larger groups. The results showed that the EduTB application has been successfully developed, with a validity testing of 0.84, categorized as valid, and the practicality of 83%, classified as practical. The practicality result was based on the perception of educators in the experimental group, which was 91%, categorized as highly practical.

Introduction The prevalence of tuberculosis (TB) deaths doubled in 2021, reaching 1.4 million people due to the impact of the COVID-19 pandemic. Global TB Report data shows an increased incident rate of 3.6% in 2020 and 2021, with Indonesia ranking as the second-highest globally for TB cases, increasing from 8.4% to 9.2% [1], [2]. In Riau Province, the Case Notification Rate (CNR) reached 134 per 100,000 population in 2021, with Treatment Coverage (TC) of only 33.5%. Pekanbaru City had the highest number of suspected cases, accounting for 3,602 patients, with a CNR of 315 per 100,000 population, a Cure Rate of 58%, and a Success Rate (SR) of 75.8% [3]. The reduction in TB patients since the pandemic suggests an increasing number of undiagnosed and untreated TB cases, leading to high community infection transmission [1], [4]. TB is an airborne disease that spreads rapidly through the air, facilitating easy transmission from positive patients to healthy individuals, such as during coughing [5]. Pulmonary TB patients with positive acid-fast bacilli (BTA+) have the potential to transmit to 10-15 people per year, increasing the possibility of infection transmission [6]. The success of TB patients in adhering to treatment is closely related to family support from fellow patients, motivating them to take medication as prescribed [7]. Consequently, establishing social support from family, friends, patient groups, peer counseling, and individual management can help patients adhere to treatment protocols [8], [9]. Several health efforts are directed toward TB patients,
