The story
Bumitama is part of the Harita Group, which was founded in 1915 by Lim Tju King. His son, Lim Hariyanto Wijaya Sarwono (President and Chair of Harita Group), took over and developed a timber business. He built a small factory and began manufacturing plywood in 1983.
With the help of his two sons, Lim Gunawan Hariyanto (CEO of Harita Group) and Gunardi Hariyanto Lim (Deputy CEO of Harita Group), the Group entered the coal mining industry through the 1985 Kelian Equatorial Mining gold project (a joint venture, Rio Tinto owned 90% and the Harita Group 10%) and the 1988 Lanna Harita coal project.
In 1996, Bumitama was established by the Harita Group with its acquisition of 17,500 hectares in Central Kalimantan and the company began its through acquisitions, and by 2007 Bumitama had 50,000 hectares of planted area. As of March 2012, just before the IPO, Bumitama had 118,000 hectares of planted area. For comparison, Singapore (where Bumitama is publicly traded) covers roughly 69,300 hectares (693 km2).
In 2007, IOI Corporation bought 33% of PT Bumitama Gunajaya Agro as part of its plan for strategic investment in Indonesia. Bumitama would benefit from IOI's technical expertise and management support, since IOI has operations throughout the palm oil supply chain and markets in more than 65 countries.
