The results of the Paired T-Test showed that the p-value of systolic blood pressure = 0.001 and the p-value of diastolic blood pressure = 0.008 (p <0.05), which means that consumption of ambon bananas is effective in reducing systolic and diastolic blood pressure. It can be concluded that there is a significant effect of banana fruit therapy of the type Musa paradisiaca Var Sapientum Linn on reducing systolic and diastolic blood pressure in hypertensive patients.
