According Mering, it is not known exactly, but it is expected the same with the tradition of the tattoo when I started the entry of missionaries into remote areas in the Dayak village in the Dutch colonial era first.
This tradition was further eroded out during a confrontation between Indonesia and Malaysia in Kalimantan border area. It was developed stigma in society, those who leaved long ears and live in long houses, inhabited by several families, a community group that is not modern. Not resistant to such views, eventually some people cut off the ear length.
The stigma of this kind continued until now. Dayak among the younger generation no longer willing to make long ears for fear of being considered obsolete and not modern.
Only a minority of the Dayak people who still adhere to the tradition of ear leaf length, and even then the amount is very minimal.
