This research method is included in comparative quantitative research. This quantitative research contained lumerical data and was processed using statistical methods. With a comparative approach, namely to determine the level of approach of a variable from two different groups.

The results of the study show that there is a Javanese perspective in looking at the characteristics of Madurese before carrying out marriages.
