Background: Breastfeeding is a valuable experience for both mother and infant, enhancing cognitive development, immunity, and emotional bonding. However, exclusive breastfeeding coverage remains suboptimal, partly due to inadequate breastfeeding technique skills among mothers. Objective: This study aims to analyze the differences in breastfeeding technique skills among pregnant women before and after a video-based educational intervention at the Gema Santi Nusa Penida Regional General Hospital, Klungkung Regency. Methods: This study utilized a pre-experimental design with a one-group pretest-posttest approach. The population consisted of 160 pregnant women visiting the Gema Santi Nusa Penida Regional General Hospital from March to April 2025. A sample of 32 pregnant women was determined using a comparative analysis sample size formula and selected via purposive sampling. Primary data were collected through observation using a validated and reliable breastfeeding technique skill checklist (calculated $r = 0.411 - 0.758 > 0.349$; Cronbach's alpha $= 0.757 > 0.6$). Results: The Shapiro-Wilk test indicated that the data were normally distributed, with values of 0.325 (pre-test) and 0.127 (post-test) $> 0.05$. The mean score for breastfeeding technique skills was 42.28 before the intervention and increased to 70.46 afterwards. The paired t-test demonstrated a significant difference in breastfeeding technique skills before and after the educational intervention ($p = 0.000 < 0.05$). Conclusion: Video media is highly effective in improving breastfeeding technique skills. Future initiatives should focus on developing more comprehensive video content to further enhance educational efficacy.
