Bontang is a city on the eastern coast of the island of Borneo in Indonesia, in the province of East Kalimantan. It occupies an area of 497.57 km2 (192.11 sq mi), and the population was 140,787 at the 2010 Census, and 178,917 as of 2020. It is also the third most densely populated place in the province after Balikpapan and Samarinda.[6]



Bontang refers to the town's traditional status throughout history as a humble village populated mostly by immigrants. ‘Bon’ can refer in Indonesian to ‘receipt’ and ‘tang’ to ‘debt.’ Alternately, the name of the town means group of visitors. A coastal town, Bontang was initially a settlement governed under the Kutai Sultanate based in Tenggarong.[7]

Colonial Era[edit]

In 1920 the village of Bontang was established as a sub-district town, which at that time was called the Onder Van Bontang District. Bontang was still a sub-district under the leadership of a wedana assistant who was a cleric in the government of Sultan Aji Muhammad Parikesit, the 19th Sultan of Kutai Kartanegara (1921-1960).

Independence Era[edit]

Since 1954, a subdistrict head has taken office. After the enactment of Law Number 27 of 1959 concerning the establishment of the Regional Level (Dati) II in East Kalimantan it removed the status of self-government.[8] In 1972 the government of the Kutai regency recognized Bontang as a district. The major development of Bontang took place after two major companies were founded there in the 1970s, PT Badak Natural Gas Liquefaction and PT Pupuk Kaltim. PT Badak established early in 1974. PT Pupuk Kaltim, a company specializing in the production of ammonia and fertilizer, followed three years later. Since 1978 Bontang experienced rapid regional growth and development. As a positive impact arising from being made Bontang as an industrial area, both by PT Badak NGL and PT Pupuk Kaltim. The two companies were building facilities and infrastructure that were very important for the economic growth of the city, so the central government planned to upgrade the status of Bontang from the sub-district into an administrative city. In 1989 its status changed to administrative city (kota administratif - kotif), by government law of No. 20 of 1989 and followed up the expansion of the Kotif region from one sub-district to two sub-districts. Namely District of North Bontang and District of South Bontang District.[7] In 1999, Bontang upgrade status to autonomous independent city (kotamadya).
