Pengaruh teh bunga telang terhadap pengendalian tekanan darah dan glukosa darah lansia

The community service carried out by the YSI MORSE FKIK UMY team was motivated by the high prevalence of degenerative diseases, particularly hypertension and diabetes mellitus, among the elderly population in Indonesia, including in Padukuhan Kweni and Padukuhan Garon. The problems found in the field show that older adults tend to rely on pharmacological treatment without accompanying changes in health behavior, while the use of non-pharmacological therapies based on local potential is still limited. On the other hand, the Panggungharjo area has the potential for butterfly pea flower (Clitoria ternatea L.) plants, which have so far been used more as ornamental plants, even though the elderly show an interest in herbal medicine. This community service activity aims to determine the effectiveness of butterfly pea flower tea consumption as a complementary non-pharmacological intervention in controlling blood pressure and random blood sugar (RBS) levels in the elderly. The method used was quasi-experimental with a one group pretest–posttest design conducted within the framework of community service with a community based intervention approach. Sampling was conducted using purposive sampling techniques involving elderly people with hypertension in Padukuhan Kweni and elderly people with diabetes mellitus in Padukuhan Garon. The intervention consisted of providing butterfly pea flower tea during 10 meetings from August 28 to October 5, 2025, with a frequency of twice a week and a recommendation to consume butterfly pea flower tea once a day. The results showed a significant decrease in systolic blood pressure from an average of 152.75 mmHg to 149.00 mmHg (p = 0.008) and diastolic blood pressure from 85.42 mmHg to 77.67 mmHg (p = 0.041). In the diabetes mellitus group, the average RBS level decreased from 229.53 mg/dL to 195.57 mg/dL, but statistically, this change was not significant (p = 0.807). Based on these results, it can be concluded that consumption of butterfly pea flower tea is effective as a complementary therapy in controlling hypertension in the elderly. However, a longer intervention duration and dietary control are needed to achieve more optimal results in controlling blood sugar levels.
