History
Establishment and early history
In 1977, an offshore fertilizer project was started on two ships owned by
Pertamina
PT Pertamina (Persero) is an Indonesian state-owned oil and natural gas corporation, headquartered in Jakarta. It was created in August 1968 by the merger of ''Pertamin'' (established 1961) and ''Permina'' (established in 1957). In 2020, the ...
, the largest Indonesian oil producer, which later became the beginning of the establishment of PT Pupuk Kalimantan Timur. The success of the project finally began the establishment of a factory covering an area of 493 ha (hectares) which was once a very dense forest area on the hillsides of the forests of East Kalimantan. Precisely on December 7, 1977, PKT was officially established. The main raw material for the plant in Bontang is natural gas which is piped from
Muara Badak
Muara Badak () is a district of Kutai Kartanegara Regency, East Kalimantan, Indonesia. As of 2023, it was inhabited by 50,435 people, and currently has the total area of 781.52 km2. Its district seat is located at the village of Muara Badak ...
, about 60 km from the factory location.
Initially the Pupuk Kaltim project was managed by Pertamina with floating fertilizer factory facilities or a factory on board. Because of some technical considerations according to Presidential Decree No.43 of 1975 the project location was transferred to land, and through Presidential Decree 39 of 1976 the management was handed over from Pertamina to the Ministry of Industry.
In 1979 the construction of the Kaltim-1 plant began and the commercial operation period was first started in 1987. The Kaltim-2 plant was built in early 1982 and completed 3 months ahead of the stipulated schedule and succeeded in achieving commercial operations faster than East Kalimantan. -1, namely in 1984. The Kaltim-1 plant and Kaltim-2 factory were inaugurated by
President Soeharto on October 28, 1984.
The Kaltim-3 plant was built in 1986 and was inaugurated on April 4, 1989. In addition, a unit for making urea formaldehyde (UFC-85) with a capacity of 13,000 tons per year was built to improve the quality of urea fertilizer produced.
Development since 1990
On November 20, 1996, an IV urea unit (POPKA) was built which aims to increase added value for residual Ammonia (Ammonia excess) and gas which is wasted into the atmosphere to produce granular urea products. The factory with a projected production capacity of 570,000 tons per year was completed on April 12, 1999. The investment value for the construction of the POPKA factory was US$44 million and Rp 139 billion.
The Kaltim 4 factory was built in 1999 with a projected capacity of 570,000 tons of urea granule and 330,000 tons of ammonia per year. Construction of the urea plant was completed in mid-2002, while the ammonia plant was completed in early 2003. In 2007, Pupuk Kaltim made the NPK factory fuse blending in Bontang to produce
NPK with phosphates imported from

.
The Kaltim 5 plant, which is planned to have a capacity of 1.2 million tons of urea per year, will soon be realized by the Kaltim-5 Factory PKT which will replace the existence of the Kaltim-1 factory unit which is likely to be closed because it is old and inefficient. To support Kaltim-5 operations, Pupuk Kaltim will also build an ammonia plant with a capacity of around 600,000 tons per year.
At present Pupuk Kaltim has five Urea fertilizer plants with a total capacity of 2.98 million tons of urea per year and four Ammonia plants with a total capacity of 1.85 million tons of Ammonia per year. While NPK fertilizer production is as much as 350,000 tons per year with factories in three cities, namely: Bontang, Semarang and Surabaya.
