<![CDATA[ABSTRACT The prevalence of stunting in West Nusa Tenggara remains high, reaching 29.8% in 2024 according to the Indonesian Health Survey (SKI), highlighting the need for nutrition interventions beginning in the preconception period. Prospective brides and grooms represent a strategic target group for stunting prevention; however, nutrition education delivered through the Offices of Religious Affairs (KUA) is predominantly focused on religious, psychological, and social aspects, while specific nutrition-related content remains limited. This study aimed to develop a Balanced Nutrition Education Module for Prospective Couples to Prevent Stunting during the First 1,000 Days of Life (1,000 HPK). A Research and Development (RD) approach using the ADDIE model was applied. The study participants included nutrition experts and health promotion media experts as validators, as well as 14 prospective couples from the KUA of Gunung Sari District, West Lombok Regency, who participated in the field trial. Data were collected through interviews, validation and practicality questionnaires, and pre-test and post-test instruments. The expert validation results indicated that the module was highly feasible, with scores of 88.46% from nutrition experts and 95.40% from media experts. The practicality assessment yielded a mean score of 92.11%, indicating a very high level of usability. The effectiveness test demonstrated a significant improvement in participants’ knowledge, with mean scores increasing from 57.14 at pre-test to 80.00 at post-test (p 0.001). In conclusion, the developed module is feasible, practical, and effective, and is recommended as a complementary educational tool in premarital counseling at KUA and primary health centers to strengthen preconception nutrition interventions.
