Mangongkal Holi is known as the highest level of tradition on Batak Toba daily life
 practices. Previously, this tradition was done by those limited families for the reasons of
 funding and its complicated management. But nowadays, the practice of mangongkal
 holi tradition is more rarely to be found; eventhough there are many local wisdom
 implicitly impressed on it. This study is part of the first writer’s dissertation, entitled
 Tradisi Mangongkal Holi pada Masyarakat Batak Toba (Mangongkal Holi Tradition in
 Batak Toba Society). This research was done in qualitative research, the data were
 collected through direct participatory observation, in-depth interviews with many batak
 toba informants (adat’s experts, practitioners and academicians/theologians), as well as
 audio-visual documentation. The data were analyzed by using Miles, and Huberman
 model; where data condensation, data display and data conclusion/verification were
 the three concurrent flows activities done to make sure the process of data analysis
 precisely on the track. The final conclusion of this research state that there were
 nine local wisdom found in mangongkal holi tradition, they are: thanksgiving, respect,
 humble/humility, blessings, responsibility, mutual cooperation, prays, concession in
 dialogue, and prestige; where all these local wisdom will be well-stored and longlasting
 while mangongkal holi tradition conserved through good and acceptable

 many solutions to solve the problems of funding, such as: down-grading the level
 of ceremony, or unifying more individual saring-sarings in a mangongkal holi ceremony.
