Brief Story

A Brief History of Pupuk Kaltim

PT Pupuk Kalimantan Timur (Pupuk Kaltim) is a subsidiary of PT Pupuk Indonesia (Persero). Initially, the Pupuk Kaltim project was managed by the state oil company Pertamina with a facility of a floating fertilizer plant or a plant on a ship. However, due to several technical considerations, the project was shifted to land in accordance with the Presidential Decree No. 43 of 1975 and later through the Presidential Decree No. 39 of 1976. With the issuance of the Presidential Decree, the management was handed over to the Ministry of Industry. Through the Minister of Industry at that time, a task was assigned to complete the construction of the largest fertilizer plant in Asia, namely Pupuk Kaltim, which was officially operated on December 7, 1977. A land area of 443 hectares in Bontang, East Kalimantan, was prepared for the construction of the project. Natural gas, which is the main raw material for the production of Ammonia and Urea, was channeled through a 60 km pipeline from Muara Badak, East Kalimantan.


The first project, which is the construction of Plant 1, started in 1979, while the construction of Plant 2 started in 1982. The two plants were inaugurated simultaneously on October 29, 1984. Subsequently, Plant 3 was built and inaugurated on April 4, 1989. In 1999, the first urea granule plant in Indonesia, namely the Kaltim Optimization Project (POPKA), was established. The plant was inaugurated on 6 July 2000 at the same time as the erection of the first pile of Plant 4. The Urea Unit of Plant 4 was inaugurated on July 3, 2002 while the Ammonia unit on June 28, 2004. In 2014 Pupuk Kaltim took over the Ammonia Plant of PT Kaltim Pasifik Ammonia (KPA), and currently the operation of the ex-KPA Plant is part of the Kaltim Optimization Project (POPKA) under the coordination of Plant 1A. Moreover, in order to support the National Food Sovereignty Program as well as to support the plantation sector and domestic industry, the Government through the Presidential Instruction No. 2 of 2010 decided to revitalize the national fertilizer industry through the replacement of a fertilizer plant that has gas consumption above 34 MMBTU per ton of Urea with a new technology plant that is more energy efficient and consumes less raw materials.


This revitalization was realized through the construction of Plant 5 which started in 2011 and was inaugurated by the President of the Republic of Indonesia Joko Widodo on November 19, 2015. In addition to being more efficient in raw materials, Plant 5 has the largest production capacity, compared to other Pupuk Kaltim’s plants. At present, the construction of these plants has become a petrochemical industrial complex consisting of five Ammonia plants, five Urea plants, three NPK Blending plants, two NPK Fusion plants, one Coal Boiler plant, bagging unit, and warehousing unit. Supported by reliable and experienced human resources, Pupuk Kaltim is ready to become a major player in a growing and sustainable world-class agrochemical-based industry.
