<![CDATA[The Maternal Mortality Rate (MMR) and Infant Mortality Rate (IMR) in Indonesia remain high. According to the Ministry of Health (2023), there were 7,389 maternal deaths and 120 infant deaths, consisting of 71 neonatal deaths and 49 post-neonatal deaths. West Sumatra ranks 10th among provinces, and Padang City ranks 1st due to preeclampsia, vaginal bleeding, postpartum infections, and unsafe abortions. The purpose of this study is to determine the effect of education through WhatsApp Groups on pregnant women's knowledge of pregnancy danger signs at the Padang Pasir Community Health Center in 2025. This quantitative study used a pre-experimental design with a one-group pretest and posttest approach. The population consisted of 134 pregnant women at the Padang Pasir Community Health Center. The study was conducted from March to August, with data collection carried out from July 1 to 23, 2025, using a questionnaire via Google Form. The sample consisted of 30 pregnant women selected using purposive sampling. Data analysis was performed using univariate and bivariate analysis with the Wilcoxon test, yielding a p-value of 0.000 (p<0.05). The results of this study indicate that the average knowledge of pregnant women before receiving education (45.66) increased after receiving education (87.50). The Wilcoxon test results show a p-value of 0.000 (p<0.05), meaning that there is an effect of education through WhatsApp Groups on the knowledge of pregnant women about danger signs of pregnancy at the Padang Pasir Community Health Center. The conclusion of this study is that there is an effect of education through WhatsApp Group on the knowledge of pregnant women about danger signs of pregnancy at the Padang Pasir Community Health Center.
