Family planning program is a global scale program that is encouraged not only to overcome the population issues but also contribute to decreasing the maternal and neonatal mortality rate. Indonesia is one of the countries that are committed to incite this program, especially among the fertile-age couples, because of the complexity of the population and health issues in this country. Nevertheless, the participation of the fertile-age couple in this program which is marked with the usage of contraceptives has not reached the expectation. The purpose of this research is to analyze the determinants or factors related to the use of contraceptives among fertile-age couples. This study uses quantitative research with cross-sectional time approach on 100 women of fertile-age couples. The variables collected by interview with questionnaire. The variables that are statistically related to the use of contraceptives are knowledge (p value=0.036, CC=0.224), culture (p value= 0.014, CC=0.257), husband support (p value=0.000, CC=0.442) and the role of health worker (P value=0.000, CC=0.417). The most dominant factor on contraceptive usage is husband support. The result of this study is expected to give information for family planning program managers for designing program to increase the usage of contraceptives in their work area.
