Hypoglycemia is a common acute complication in patients with Type 2 Diabetes Mellitus (T2DM) that may result in serious health consequences when not recognized and managed promptly by family members. Adequate family knowledge is essential to support early detection and appropriate management of hypoglycemic episodes at home. This study aimed to compare the effectiveness of a Sundanese philosophy-based educational video incorporating the values of Silih Asah, Silih Asih, and Silih Asuh (3SA) with a leaflet in improving family knowledge regarding hypoglycemia management among T2DM patients. A quantitative quasi-experimental study with a pretest-posttest control group design was conducted involving 78 family members of T2DM patients, consisting of an intervention group receiving the 3SA educational video (n=39) and a control group receiving a leaflet (n=39). Knowledge levels were measured before and after the intervention using a structured questionnaire and analyzed using the Wilcoxon Signed Rank Test and Mann-Whitney U Test. The results demonstrated a significant increase in knowledge scores in both the intervention group (p<0.001) and the control group (p<0.001). However, no statistically significant difference was found between the two educational media regarding post-test knowledge outcomes (p=0.715). These findings indicate that both the 3SA-based educational video and leaflet are equally effective in enhancing family knowledge of hypoglycemia management. The study suggests that either educational medium can be utilized in community health promotion programs according to local cultural contexts, participant characteristics, and available healthcare resources.
