Hipertensi merupakan penyakit tidak menular yang ditandai dengan peningkatan
tekanan darah sistolik 140 mmHg dan/atau tekanan darah diastolik 90 mmHg.
Tujuan penelitian ini adalah untuk mengetahui pengaruh konsumsi seduhan bubuk
kayu manis terhadap penurunan tekanan darah pada penderita hipertensi di Posyandu
Sehat Berseri Puskesmas Simpang IV Sipin Kota Jambi. Penelitian ini merupakan
penelitian kuantitatif dengan desain pre-experimental menggunakan pendekatan one
group pretest-posttest design. Intervensi berupa konsumsi seduhan bubuk kayu manis
yang diberikan selama 6 hari berturut-turut, kemudian dilakukan pengukuran posttest
pada hari ke-7. Pengumpulan data menggunakan lembar observasi dengan jumlah
sampel 15 responden. Penelitian ini dilakukan pada tanggal 1-7 juni 2026. Analisis data
dalam penelitian ini menggunakan analisis univariat dan bivariat dengan uji paired t-
test. Hasil penelitian menunjukkan bahwa rata-rata tekanan darah sistolik sebelum
intervensi adalah 147,80 mmHg dan rata-rata tekanan darah diastolik 90,73 mmHg,
sedangkan setelah intervensi rata-rata tekanan darah sistolik menurun menjadi 130,53
mmHg dan rata-rata tekanan darah diastolik menjadi 83,00 mmHg. Hasil uji paired t-
test menunjukkan nilai p-value sistolik < 0,001 dan diastolik < 0,001 ( = 0,05).
Sehingga dapat disimpulkan bahwa konsumsi seduhan bubuk kayu manis berpengaruh
signifikan terhadap penurunan tekanan darah pada penderita hipertensi di Posyandu
Sehat Berseri Puskesmas Simpang IV Sipin Kota Jambi.

Hypertension is a non-communicable disease characterized by an elevation in systolic
blood pressure equal to or greater than 140 mmHg and or diastolic blood pressure
equal to or greater than 90 mmHg. The objective of this study was to determine the
effect of cinnamon powder infusion consumption on blood pressure reduction in
hypertensive patients at Sehat Berseri Integrated Healthcare Center Simpang IV Sipin
Public Health Center Jambi City. This research was a quantitative study utilizing a
pre-experimental design with a one group pretest posttest design approach. The
intervention consisted of consuming a cinnamon powder infusion administered for 6
consecutive days, followed by a posttest measurement on the seventh day. Data
collection was performed using observation sheets with a sample size of 15
respondents. This study was conducted from June 1 to June 7 2026. Data analysis
involved univariate and bivariate analyses using the paired t test. The results
demonstrated that the mean systolic blood pressure prior to intervention was 147.80
mmHg and the mean diastolic blood pressure was 90.73 mmHg. Following the
intervention, the mean systolic blood pressure decreased to 130.53 mmHg and the
mean diastolic blood pressure decreased to 83.00 mmHg. The paired t test yielded a
systolic p value of less than 0.001 and a diastolic p value of less than 0.001 with an
alpha level of 0.05. Therefore, it can be concluded that the consumption of cinnamon
powder infusion significantly affects blood pressure reduction among hypertensive
patients at Sehat Berseri Integrated Healthcare Center Simpang IV Sipin Public
Health Center Jambi City.
