History

Kutai Kartanegara Regency lies in the historical region of Kutai, home to the first and oldest Hindu kingdom of Indonesia, the Kutai Martadipura Kingdom founded in the 4th century CE by King Kudungga.

Between 3 January 1953 until 21 January 1960, this area was known as the Special Region of Kutai, the last political iteration of the Sultanate of Kutai. Following its dissolution (de jure on 26 June 1959), it was subsequently split into three entities: Balikpapan, Samarinda, and its remainder, known as the Kutai Regency. Since then, it has been governed by civilian officials instead of the sultanate family. Kutai remained the largest regency by area in its province and additionally shared an international border with the Kapit Division (Sarawak, Malaysia) until 4 October 1999; when the regencies of East Kutai, West Kutai, and Bontang city were formed out of the regency.

On 23 March 2002, it was officially renamed to its present name, the Kutai Kartanegara Regency, following the release of a decree regarding that matter by the Regional House of Representatives (DPRD) of Kutai Regency on 26 June 2001.

Bukit Bangkirai rainforest

Bukit Bangkirai (Bangkirai Hill) is a 1,500-hectare natural tropical located about 58 kilometres (around 45 minutes by car) from the city of Balikpapan.'Bukit Bangkirai a rainforest wonderland', The Jakarta Post, 16 June 2007. Plants of the family Dipterocarpaceae dominate in the area, especially Bangkirai trees (Shorea laevis of the genus Shorea) growing to 40–50 metres in height. There are over 120 bird species as well as gibbons (Müller's Bornean gibbon), macaque monkeys (Southern pig-tailed macaques, Crab-eating macaques), Maroon leaf monkeys, Banded pigs, and Banggai crows. Black Orchids (Coelogyne pandurata), among 45 kinds of orchids, are endemic to Bukit Bangkirai.

To visit the forest, visitors can walk along a 64-metre canopy bridge that connects five big Bangkirai trees 30 metres above the ground.

Places of interest Mangrove information, research center In 2011, East Kalimantan province developed an 18-hectare plot of land for mangrove information and research center in Sepatin village, in Anggana District, as Bali has done. It will function as a research, exhibition, information, breeding as well as education center on mangroves, especially in the Mahakam Delta.

Smart city In early 2015 it was announced that part of Kutai Kartanegara Regency had been selected to be a trial 'smart city', the first in Indonesia, based on the Fujisawa Sustainable Smart Town (SST) concept. The aim of the SST concept was to reduce emissions by 70 percent and reduce consumption of water by 30 percent. The Kutai Kartanegara area was chosen as a trial area because of good investment growth in the region, the extensive area, relatively moderate levels of population density, effective planning in the area, and rich energy resources.
