The community in this village consists of 150 heads of households whereby 90% earn a living by farming. The community manages various kinds of horticulture plants, especially vegetables and fruits, i.e. corn. The Geographic Village, which is located near to (± 8 km) the bottom of Sinabung mount, causes people often get crop failures, since the hot wind released from the Sinabung mount. Especially at the dry season, since the village is far from the source of water, therefore only relies on rain drops both for daily needs and for their agricultural lands. Failure of this harvest can reduce the economic welfare level of the community in the village.
