This research aims to explain the effect in using simulation to develop students' educated character in learning economics. The quantitative analysis uses pre- and post-test experimental design, while descriptive analysis is completed with percentage analysis and the category of the mean score. Instruments of data collection use observation rule and questionnaire by using four scale assessments start from very good/strongly agree until very bad/strongly disagree. The result of the research shows that there are different characters in education development before and after implementation simulation in learning economics. The use of simulation in learning economics has an effect on the development of student character education. The simulation in learning economics can develop the students' character with very good category, with a total percentage that shows the number of good at 56.29% and very good at 42.71%. Through simulation, learning economics conducted is easier to develop the very important character education in students' life. The simulation which presents the real situation in learning economics improves the students' learning experience in economics field, so that the students can feel that real condition, especially for learning activity to do the economical activity by implementing good characters (by using good ways) and avoids the bad ways which can be harmful for others.
