The material provided regarding contraceptive information using the WHO Contraception application in choosing contraception, even though it uses English, respondents can understand it, then the evaluation is carried out by comparing the pretest and post-test questionnaires that have been given to respondents a week later which has been determined by the researcher. According to the researcher's assumption that the mother's knowledge of the mother's cognitive ability where the mother's knowledge is at the level of knowledge . about all contraceptive information, be it what contraception is, types of contraception, side effects of contraception, besides that the mother is also in the level of understanding . about all contraceptive information, be it what contraception is, types of contraception, side effects of contraception. The posttest results showed that all mothers had good knowledge, which means that there was a change after being given the use of the WHO Contraseption application, respondents were able to apply it, this application is useful for choosing contraception that is appropriate to the respondent's condition. Changes in respondent knowledge occurred due to counseling on the use of this application, which was given using the question and answer lecture method and conducting demonstrations so that respondents could understand the use of the application, even though it uses English, respondents could understand it, based on Rabia's research that this contraceptive guide application helps respondents in choosing contraception when women experience health problems before using contraception. These results reinforce that digital-based educational approaches such as the WHO Contraception application can be a strategic alternative in improving reproductive health literacy, especially among women of childbearing age who have limited access to direct counseling. This application also provides flexibility for users to access information anytime and anywhere, so that the learning process becomes more independent and sustainable. In addition, the increase in knowledge that occurred shows that digital interventions can strengthen women's role in making decisions regarding their own reproductive health. With better understanding, women tend to choose contraceptive methods that are appropriate to their needs, health conditions, and future pregnancy plans. This is very important in supporting the success of the Family Planning program and reducing the number of unplanned pregnancies. Not only that, the successful use of this application also shows that language barriers can be overcome with appropriate and interactive information delivery methods. Although the application uses English, through intensive assistance and varied learning methods such as lectures and Q&A, respondents can still understand the contents of the material well. Thus, this study can contribute to the world of midwifery and public health in developing innovative educational methods that are effective and adaptive to technological developments. Similar interventions can be recommended for implementation on a wider scale as part of a national strategy to improve the quality of family planning services and reproductive education.
