Abstract

This study aims to determine the effect of soursop leaf herbal tea consumption on reducing stress levels among new students at MAN Insan Pakar OKI. The research employed a laboratory and field experimental method using a One-Group Pre-Test-Post-Test Design. The stages included the preparation of soursop leaf tea, phytochemical tests (Benedict, FeCl₃, and saponin), microbiological tests (TPC, Salmonella sp., and E. coli), and psychological assessment using the DASS-42 questionnaire. A total of 90 respondents consumed one cup of soursop leaf tea daily for seven days, with stress levels measured before and after the intervention. The results indicated a significant decrease in DASS-42 scores (t = 9.12; p < 0.001) with a large effect size (Cohen's d = 1.15). These findings suggest that soursop leaf tea has the potential to serve as a functional herbal beverage that is safe for consumption and supports students' psychological well-being in adapting to a boarding school environment.
