The study used a quantitative approach with a quasi-experimental method and a nonequivalent control group design. Sampling was done by a random sampling technique with a purposive sampling type. Data were collected through observation, questionnaires, and documentation with simple linear regression analysis assisted by SPSS 16 software for Windows. The results show that the average value of emotional intelligence in the experimental class is 79.4% (high-level category), while the control class is 72% (medium-level). On the other hand, the character of manners in the experimental class is 79% (very good category), and in the control class is 72% (sufficient category). The results indicate that there is an influence of students’ emotional intelligence on their manners and characters. The results of a simple regression test in the experimental class are Y = 11.354.–0.861 with a significant value of 0.00. The significance value is <0.05 (0.00<0.05), then Ha is accepted and Ho is rejected. The results of a simple regression test in the control class are Y = 17,323- 0.760 with a significant value of 0.00, the significance value <0.05 (0.00 <0.05), then Ha is accepted and Ho is rejected.
