Adat Social Structure
It has been stated above that not only did adat include tradition, custom, convention and law, but it also included a kind of social structure. The social structure bound by a common adat was typified by small-scale communities of people in villages or of nomads wandering over a specific area. These communities were rather like miniature democratic republics. Their headmen were elected from the descendants of the oldest branch of the tribe, and they saw to the needs and interests of the community, assisted by a council of elders. Really important decisions were taken by collective deliberations, called as mupakat. Naturally in a democracy of this type, in which a premium is put on unanimity of opinions, the position of the balai was extremely important. This was the building in which meetings and discussions were held. We can think them as the centers of social life within these small communities (Alisjahbana 1961:14-15).
The principal duty of the village government was to administer the adat handed down from generation to generation, and to settle any disputes that might arise. However, the actual scope of administration within this indigenous Indonesian society was very broad if one compared it to the scope of governmental activity today. it included the regulation of marriage ceremonies, crop cultivation, distribution of the harvest, division of legacies, etc., quite apart from attending to the daily needs of the community (Alisjahbana 1961:15).
