Background: Multidrug-Resistant Tuberculosis (MDR-TB) remains a major public health challenge in Indonesia. Objective: To identify spatial clusters of MDR-TB in Jambi City during 2020–2025. Methods: A total of 101 MDR-TB cases were geocoded based on patient residential addresses to obtain precise geographical coordinates. A retrospective space-time scan analysis was then performed using population and MDR-TB incidence data. The SaTScan™ software with the discrete Poisson model was applied to detect areas at higher risk. The analysis covered the period from January 1, 2023 to August 31, 2025. Results: 101 MDR-TB cases were recorded during the study period. The analysis identified two cluster. The first cluster located around (1.1571425 S, 103.598028 E) with a radius of 5.44 km, comprising 28 observed cases compared to 10.00 expected, with a relative risk (RR) of 3.49 (p = 0.0037). The second cluster not reached the statistical significance was cantered at (1.638602 S, 103.577643 E) with a radius of 2.22 km, including 3 observed cases compared to 0.46 expected with an RR of 6.74 (p = 0.99). Conclusion: Spatial concentrations of MDR-TB were observed in areas of Jambi City. Strengthened surveillance, integration of spatial analysis into TB control programs are recommended to support targeted interventions.
