History

Map of Onderafdeeling Pasir [id]
Former coat of arms until renaming in 2007

On 26 June 1959, Pasir was first established as a regency in East Kalimantan, after being separated from Kotabaru in South Kalimantan, for "historic and social-economic reasons". At the time of its formation, it originally consisted of four districts as mentioned: Central Pasir, North Pasir (not to be confused with Penajam North Paser), Pasir Hulu, and South Pasir.[5] Meanwhile, it largely inherited the borders from Onderafdeeling Pasir [id], with the exception of parts south of modern East Kalimantan–South Kalimantan border (still part of Kotabaru till this day). Little are known the archives relating to its separation from South Kalimantan.[6]

Twenty-eight years later, on 13 October 1987, Pasir annexed the district of Penajam, then known as Balikpapan Seberang.[7] Four northeastern districts, namely Penajam, Sepaku (created in 1996), Waru, and Babulu (also created in 1996), were later separated on 10 April 2002 to form Penajam North Paser.[8] On 22 August 2007, Pasir was officially renamed to Paser by the regional government.[2]

Administrative districts

edit

Following the separation of the districts in the northeast to form the new Penajam North Paser Regency on 10 April 2002, the residual Paser Regency is now divided into ten districts (kecamatan), tabulated below with their areas and their populations at the 2010 Census[3] and the 2020 Census,[4] together with the official estimates as of mid 2025.[1] The table also includes the locations of the district administrative centres, the number of administrative villages in each district (totalling 5 urban kelurahan and 139 rural desa), and its postal codes.

Proposals have been under consideration for the existing regency to be split in two, with separate regencies being formed for South Paser and for Central Paser. The proposed South Paser Regency (Indonesian: Kabupaten Paser Selatan)[9] would comprise five districts in the south and west (specifically Batu Sopang, Muara Komam, Muara Samu, Batu Engau and Tanjung Harapan) with its capital at Batu Sopang, a combined area of 5,941.34 km2 and a population of 86,886 as at mid 2025. The proposed Central Paser Regency (Indonesian: Kabupaten Paser Tengah)[10] would comprise five districts in the centre and east (specifically Long Kali, Long Ikis, Kuaro, Tanah Grogot and Pasir Belonglong) with its capital at Kuaro, a combined area of 5,662.60 km2 and a population of 228,147 as at mid 2025.
