Jakarta officially known as the Special Capital Region of Jakarta (Indonesian: Daerah Khusus Ibu Kota Jakarta), is the capital and largest city of Indonesia, and one of the most populous urban agglomerations in the world.
Located on the northwest coast of Java, Jakarta is the country’s economic, cultural and political centre, and with a population of 9,761,407 as of December 2012, it is the most populous city in Indonesia and in Southeast Asia.
The official metropolitan area, known as Jabodetabek (a name formed by combining the initial syllables of Jakarta, Bogor, Depok, Tangerang and Bekasi), is the second largest in the world, yet the metropolis’s suburbs still continue beyond it. The metropolitan has an area of 4,383.53 square kilometres (1,692.49 sq mi) and population of well over 28 million.
Established in the fourth century, the city became an important trading port for the Kingdom of Sunda. It was the de facto capital of the Dutch East Indies (known as Batavia at that time) and has continued as the capital of Indonesia since the country’s independence was declared in 1945.
Banten is a province of Indonesia. Bordering Jakarta, it is the westernmost province on the island of Java, and its capital is Serang. The population of Banten was officially estimated at 11,834,087 at the start of 2014, up from over 10.6 million during the 2010 census. Formerly part of the province of West Java, Banten became a separate province in 2000. The province is a transit corridor to Sumatra
The Baduy (or Badui), who call themselves Kanekes, are a traditional community living in the western part of the Indonesian province of Banten, near Rangkasbitung. Their population of 11,700 is centered in the Kendeng mountains at an elevation of 300–500 meters (975′-1,625′) above sea level.
Their homeland in Banten, Java is contained in just 50 km2 (19 sq mi) of hilly forest area 120 km (75 mi) from Jakarta, Indonesia’s capital
Ethnically the Baduys belong to the Sundanese ethnic group. Their racial, physical and linguistic traits bear much resemblance to the rest of the Sundanese people; however, the difference is in their way of life. Baduy people resist foreign influences and vigorously preserve their ancient way of life, while modern Sundanese are more open to foreign influences and a majority are Muslims.
The Baduy are divided into two sub-groups; the Baduy Dalam (Inner Baduy), and the Baduy Luar (Outer Baduy). No foreigners were allowed to meet the Inner Baduy, though the Outer Baduy do foster some limited contacts with the outside world.
