Background: Adolescents are expected to be able to build strong resilient families that will help achieve global development goals. The number of children in the family contributes to family resilience because it influences parenting and child development. The use of contraception is expected to help regulate the number of children and build a happy and prosperous family.

Purpose: The purpose of this study is to describe adolescent family planning and adolescent preferences regarding contraceptive use in the future.

Method: This study uses qualitative research methods by using in-depth interviews. Research informants were determined using purposive sampling. 40 adolescents were interviewed in this study related to their demographic characteristics, knowledge of family planning, number of children desired, interest in using family planning, and exposure to information. The data obtained were then analyzed using content analysis.

Results: Most teenagers plan to marry over the age of 25, have 2-4 children, and use contraception in the future. Knowledge, access to information, number of siblings, and perceptions about the number of children contribute to family life planning in adolescents. Condoms, pills, and injections are contraception that will be used in the future. The most frequently mentioned source of information is lecture material and social media.

Conclusion: Youth have a good understanding of the importance of family planning and the benefits of family planning programs. However, family background contributes to the number of children desired and the preference for contraceptive methods. Adolescent Family Development is needed to improve the understanding of adolescent families about family planning programs.
