A door-to-door, community-based educational intervention using videos and infographics significantly improved residents' knowledge of hypertension control.
Hipertensi merupakan penyakit tidak menular dengan prevalensi tertinggi (32,0%) di RT 04 RW 05 Kelurahan Klatak, Kabupaten Banyuwangi, melampaui prevalensi nasional (30,8%), dengan akar masalah berupa rendahnya pengetahuan warga, tingginya konsumsi garam, kurangnya aktivitas fisik, dan minimnya media edukasi yang menarik. Program pengabdian LENSA SEHAT (Langkah Edukasi Nyata Sasaran Hipertensi) ditawarkan sebagai solusi berupa sosialisasi kesehatan berbasis video dan infografis yang dilaksanakan secara door-to-door kepada 30 warga usia 18–65 tahun selama tiga hari (25–27 Juni 2026). Metode pelaksanaan meliputi pengisian pre-test, pemutaran video edukatif, pembagian infografis, dan pengisian post-test, dengan analisis data menggunakan uji Wilcoxon Signed-Rank Test dan ukuran efek Cohen's d. Hasil kegiatan menunjukkan peningkatan rata-rata skor pengetahuan dari 83,33 menjadi 91,33 (p = 0,028) dengan efek sedang-kecil (d = 0,43), serta peningkatan proporsi peserta berkategori pengetahuan baik dari 80,0% menjadi 96,7%. Program ini berhasil menjangkau seluruh sasaran (ketercapaian 100,0%) dan terbukti efektif meningkatkan pengetahuan warga tentang pengendalian hipertensi, sehingga dapat dijadikan model intervensi promotif-preventif berbasis komunitas pada skala RT.

Cahyawan et al. (2026) studied Hypertension (n=30). LENSA SEHAT program (video and infographic-based health education) vs. Pre-intervention baseline was evaluated on Average hypertension knowledge score (0-100 scale) (Cohen's d 0.43, p=0.028). The LENSA SEHAT video and infographic-based educational program significantly increased residents' average hypertension knowledge scores from 83.33 to 91.33 (p = 0.028, Cohen's d = 0.43).
