These include Enim, Musi, Rawas, and Ogan proper. Agriculture is the principal economic activity of the Ogan. Rice, rubber, and coffee are the main crops cultivated. Wet rice plots are still worked mostly by water buffalo. Planting is done by groups of five to ten people, working either for wages or as a part of a rotating work group.
Harvesting is done by mixed-sex work groups or by the farming family.
Ogan villages usually contain from 300 to 400 households. Dwellings are generally single-family structures of three or four rooms. The houses are raised on stilts, with the lower part being used for storage or trade. In upstream Ogan territory, specific skills are associated with particular villages. In addition, each village has stories of its founding and conversion to Islam that set it apart from other villages.
