This study aims to find out and analyze the influence of Unsuitable Drinking Water Sources and Unsuitable Latrines on the incidence of Stunting in Sampanahan District, Kotabaru Regency. The object of the study is the Effect of Improper Drinking Water Sources and Unsuitable Latrines on Stunting Incidence. Meanwhile, the subjects in this study are the population and research sample consisting of children under five years old (toddlers) in Sampanahan District, Kotabaru Regency. There are 2 (two) variables used in this study, namely dependent and independent variables. The dependent variable is Stunting Occurrence. Independent variables are Unsuitable Drinking Water Sources and Unsuitable Latrines. The research method uses a correlation research type with a quantitative approach and uses a descriptive research type with a qualitative approach. The analysis used in this study is a mixed approach consisting of Descriptive Statistics, Multicollinearity Test, Overall Model Fit Test, Nagelkerke's R Square Test, Model Conformity Test, Classification Matrix, Wald Test, Logistic Regression Analysis and Interview. Based on the results of the study, quantitatively, the variable of unsuitable drinking water source (X1) had no effect on the incidence of stunting (Y) with a p-value of 0.376 > 0.05. The variable of unsuitable toilets (X2) had no effect on the incidence of stunting (Y) with a p-value of 0.756 > 0.05. Meanwhile, qualitatively, the variables of drinking water sources are not suitable and latrines are not suitable to affect the incidence of stunting.
