Diabetes mellitus merupakan salah satu penyakit tidak menular dengan prevalensi yang terus meningkat dan berisiko menimbulkan komplikasi serius akibat kadar glukosa darah yang tidak terkontrol. Upaya pengendalian tidak hanya dilakukan secara farmakologis, tetapi juga melalui pendekatan nonfarmakologis berbasis edukasi dan perubahan perilaku. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pengetahuan dan keterampilan penderita diabetes mellitus dalam mengendalikan kadar glukosa darah melalui terapi nonfarmakologi. Kegiatan dilaksanakan di Polindes Gampong Sidodadi, Kecamatan Langsa Lama, Kota Langsa, pada 31 Agustus–1 September 2025 dengan sasaran 15 penderita diabetes mellitus. Metode yang digunakan meliputi pretest, edukasi interaktif, simulasi dan demonstrasi terapi nonfarmakologi berupa senam kaki diabetes, relaksasi autogenik, dan relaksasi otot progresif, serta posttest. Selain itu dilakukan pemeriksaan kadar glukosa darah peserta. Hasil pemeriksaan menunjukkan sebagian besar peserta memiliki kadar glukosa darah di atas nilai normal (114–428 mg/dl). Evaluasi pengetahuan menunjukkan peningkatan kategori baik dari 33,3% pada pretest menjadi 86,67% pada posttest. Peserta juga menunjukkan partisipasi dan antusiasme tinggi selama kegiatan. Program ini berkontribusi dalam meningkatkan literasi kesehatan dan kemampuan praktik terapi nonfarmakologi sebagai upaya pendukung penurunan dan stabilisasi kadar glukosa darah. Model edukasi dan pendampingan ini berpotensi direplikasi sebagai strategi promotif–preventif berbasis komunitas. Education and Assistance in Non-Pharmacological Therapy for Blood Glucose Control among Patients with Diabetes Mellitus in Sidodadi Village Diabetes mellitus is a non-communicable disease with an increasing prevalence and a high risk of complications due to uncontrolled blood glucose levels. Blood glucose control can be achieved not only through pharmacological treatment but also through non-pharmacological approaches that emphasize education and lifestyle modification. This community service program aimed to improve the knowledge and skills of patients with diabetes mellitus in controlling blood glucose levels through non-pharmacological therapy. The activity was conducted at the Village Maternity Post (Polindes) of Sidodadi Village, Langsa Lama District, Langsa City, on August 31–September 1, 2025, involving 15 participants diagnosed with diabetes mellitus. The methods included a pretest, interactive health education, simulation and demonstration of non-pharmacological therapies such as diabetic foot exercises, autogenic relaxation, and progressive muscle relaxation, followed by a posttest. Blood glucose level measurements were also performed as part of health screening. The results showed that most participants had blood glucose levels above normal ranges (114–428 mg/dl). Knowledge evaluation demonstrated a substantial improvement, with the proportion of participants in the “good” knowledge category increasing from 33.3% in the pretest to 86.67% in the posttest. Participants showed high enthusiasm and active participation throughout the program. This community service activity contributed to improving health literacy and empowering patients to apply non-pharmacological therapies to support blood glucose reduction and stabilization. The program offers a community-based promotive and preventive model that can be replicated in similar settings
