Unintended pregnancy and pre-marital sex are common in adolescents due to the lack of understanding about Adolescent Sexual and Reproductive Health (ASRH), family planning, and/or birth control.
The purpose of this study was to classify unintended pregnancy and pre-marital sex among adolescents in East Java to find the factors behind them.
The data used in this research included women of childbearing age based on SKAP by BKKBN in 2019. This study employed SMOTE-NC as a method for handling imbalanced data and random forest as a classification method.
The result of this study showed that the most influential variable was education and domicile for unintended pregnancy and pre-marital sex, respectively.
