This study aims to describe the teacher's efforts in developing moral values-based character. This type of research is descriptive qualitative. The technique of collecting data in this research is by using observation, interview, and documentation. The results of this study show that of 19 students, there are two students who have different characters and if the teacher gives lessons to the students, it turns out the two students are just playing. These two students also handed in their assignments to the last minute. It revealed that the nature of the two students was influenced by the environment and also the influence of the background of parents of students whose job is only farmers and motorcycle taxi drivers. The condition makes the students less motivated in getting involved in the learning process at school. In conclusion, the teacher has tried to advise, give warning, light punishment, and yet both students keep on doing things that make other students less happy.
