Pregnant adolescents aged 10-19 years have a higher risk of eclampsia, endometriosis, systemic infections, and undergoing abortion. Adolescents require reproductive health education, particularly related to preconception, to increase knowledge about pregnancy preparation using appropriate, interesting, and easily accessible media, such as video. Aims: The aim of this study is to find out the influence of health education using video media on preconception knowledge in female adolescents in SMA Muhammadiyah 1 Sragen. Methods: The type of study was quantitative using a pre-experimental method with a one-group pre-test and post-test design. The population of the study was 245 respondents. The sampling technique used was purposive sampling with 71 respondents. The instrument of the study was a preconception knowledge questionnaire, which has been tested for its validity and reliability. Results: The results of the study showed that the average age of respondents was 17 years old. Before receiving health education using video media, 47 respondents (66,2%) had a moderate knowledge level, and after health education using video media, 63 respondents (88,7%) had a good knowledge level.
