Implementation of Moran Index-Based Geographic Information System on Tuberculosis Case Distribution: Case Study at Batujajar and Bayongbong Community Health Centers, Indonesia
Abstract
This study examines the spatial distribution of tuberculosis (TB) cases using the Global Moran’s I Index in two regions: Batujajar and Bayongbong Community Health Centers, West Java, Indonesia. Using a correlational design and secondary data (2023–2024), TB cases were analyzed with Geographic Information System (GIS). Results show significant spatial clustering in Batujajar (Moran’s I = 0.329; z = 4.038; p < 0.01), with cases concentrated near industrial areas and water bodies, indicating environmental and demographic influences. In contrast, Bayongbong shows no significant spatial autocorrelation (Moran’s I = -0.131; p = 0.982), suggesting random distribution. These findings highlight the need for targeted interventions in clustered areas and broader strategies in dispersed regions, supporting improved TB control and resource allocation.
