Diagnosis of control was based on clinical diagnosis and examination of blood sample with Leptotek Lateral Flow. The data was analyzed in univariate, bivariate and multivariate tests using logistic regression. Result : The results of this research found that physical environmental factors that influenced the incidence of leptospirosis were stagnant water of the ditch (OR = 3.5; 95% CI: 1,282-9,301; p = 0.014) and habit of taking bath or washing in the river (OR = 7.5; 95% CI: 1.534- 36.185; p = 0.014). Recomendation: It was sugested for Health Departement to control the risk factors of physical environment by cooperating with relevant agencies, especially PROKASIH (Clean River Program).
