Hypertension or high blood pressure is a degenerative disease. Hypertension can attack people of all ages, including the elderly. One way to deal with the problem of hypertension is by giving orange juice. Orange juice is considered to have quite effective ingredients in lowering blood pressure. The aim of this research was to determine the effect of orange juice on blood pressure in elderly patients at RSU Prasetya Bunda Tasikmalaya. Quantitative research method with pre-experimental methods. The sample in this study was 18 hypertensive patients obtained using a (total sampling technique). Data analysis used the dependent T test (paired). The results of this study showed that the average blood pressure before was 153.89/95.83 mmHg and the blood pressure after was 141.11/85.78 mmHg. The results of the paired T-test for systolic blood pressure p value=0.000 and diastolic blood pressure p value=0.000 (p≤0.05) So the hypothesis is accepted. The conclusion from this research is that orange juice therapy can reduce blood pressure in elderly people with hypertension. This research suggestion can be used as a reference in providing nursing care to elderly people who experience hypertension and health education about the use of orange juice as a non- pharmacological treatment to lower blood pressure in elderly people who experience hypertension without having to cause side effects.
