Abstract

Leprosy is a chronic infectious disease caused by Mycobacterium leprae and remains a public health problem in several regions of Indonesia, including Central Java Province. This study aims to statistically analyze the distribution of leprosy cases in Central Java Province in 2018–2019 based on data from the Central Java Provincial Statistics Agency (BPS), sourced from the Health Office. Central Java Province. The methods used include descriptive statistical analysis, measures of central tendency and dispersion, spatial distribution analysis across regencies/cities, and interpretation of interregional case trends. The analysis results show that there are significant variations in the number of cases across regencies/cities. Brebes, Pemalang, Tegal, and Blora Regencies are categorized as areas with relatively high numbers of cases, while several cities such as Magelang City and Salatiga City have relatively low numbers of cases. In total, the number of leprosy cases in Central Java in 2018 and 2019 was recorded at 2,133 cases. This uneven distribution indicates the presence of risk factors such as social conditions, population density, and access to healthcare services that influence disease spread. This analysis suggests that health policy approaches should be targeted (targeted intervention) toward areas with high case numbers in order to reduce transmission and prevent disabilities due to delayed diagnosis.
