Peer education is empowerment program of peers to provide information and knowledge for adolescent health. The purpose of this study was to determine the effect of peer education on adolescent premarital sexual behavior. The study was conducted in the Pasir Gunung Selatan Village, West Java. The study was quasiexperimental with one group (pretest-posttest) design. The respondents were 32 adolescents. The results showed that majority of the respondents were in the middle age stage (15-17 years) and (55.5%) of the respondents were male. Bivariate analysis showed that there was a significant difference between the average adolescent premarital sexual behavior before and after the implementation of peer education (ρ<0.05). It is suggested to public health centers to develop a Youth Care Health Services (PKPR) program as an extension of the peer educators so that efforts to improve adolescent reproductive health can be optimalenadolescentspeer educatorspre-marital sexual behaviorUR-Proceedings
