Kalimantan

Kalimantan is the Indonesian portion of the island of Borneo. It comprises 73% of the island's area. The non-Indonesian parts of Borneo are Brunei and East Malaysia. In Indonesia, "Kalimantan" refers to the whole island of Borneo. In 2019, the Indonesian President Joko Widodo proposed that Indonesia's capital be moved to Kalimantan.
Etymology.
The name "Kalimantan", was derived from the Sanskrit word "Kalamanthana", which means "burning weather island", or island with a very hot temperature, to describe its hot and humid tropical climate. It consists of the two words "kal[a]" ("time, season, period") and "manthan[a]" ("boiling, churning, burning"). The indigenous people of the eastern region of Borneo referred to their island by the term "Pulu K'lemantan" or "Kalimantan" by the time the Portuguese explorer Jorge de Menezes made contact with them. Its association with the island and its peoples has also been attributed to British scientist and colonial administrator Charles Hose from the early 20th century. However, the use of this term to refer to a supposed Klemantan people has since been discontinued, as it has been deemed to be an invented term of convenience that does not properly represent the people it claims to describe.
Area.
The Indonesian territory makes up 73% of the island by area, and 69.5% (13,772,543 at the 2010 Census of Indonesia, and 16,379,977 according to the mid-2019 official estimates) by population. The non-Indonesian parts of Borneo are of Brunei (400,000) and East Malaysia (5,625,000), the latter comprising the states of Sabah, Sarawak and the federal territory of Labuan. The region within Indonesia is also known as Indonesian Borneo.
