Many sexually active adolescents have been doing premarital sex. Based on the Cairo 1994 commitment, adolescents have freedom to think and have rights
to make decision on reproductive health. Therefore, adolescents have rights to involve in the family planning and contraceptive services. The objective of
this research is to identify knowledge and attitude on contraceptive use among “sociable” adolescent girls. This research uses cross sectional design with
subjects of “sociable” adolescent girl age 15 to 24 years old who usually socialize in Parkir Timur Senayan, Southern Jakarta in Saturday night. Samples were
taken by Quota Sampling. The result shows that “sociable” adolescence girl in Parkir Timur Senayan have good knowledge (54,1%) and good attitude of
using contraceptive (57, 1%). The result also shows that there is no significant relationship between knowledge and attitude of using contraceptive. Therefore,
we need to promote adolescent’s reproductive health, sexual education and programs on adolescent reproductive health service in a comprehensive and integrated
ways to improve adolescent reproduction health situation and adhere to religious and cultural norms. There is a need to improve and to refine research
