J-3-2-CEMENTITS–Cement is pivotal for such countries as Indonesia to support its developmental efforts. The government of Indonesia started to prioritize the development of cement industry a long time ago. In a relatively short period, the Indonesian cement industry changed from the biggest cement importing country to the biggest cement producing country in South East Asia. The largest Indonesian cement producer by capacity is PT Semen Gresik. It is a state-owned company, which traces its roots back to Gresik, East Java in 1957. Starting with just one 0.25Mt/yr wet-process kiln, the company has grown massively over the past 50 years, expanding the original site and opening plants at Tonasa, Tuban and Indarung through its subsidiaries.
The group has added capacity at Tonasa through its subsidiary PT Semen Tonasa, which operates three plants at a single site. In 2012, the Tonasa site was expanded to accommodate a fourth plant, bringing an additional 2.5Mt/yr online. Semen Gresik has a second cement-producing subsidiary, PT Semen Padang, which operates a 5.24Mt/yr plant at Indarung in North Sumatra.
Indocement (Heidelberg Cement) was established in 1975, but since 2001 it has been majority-owned by Germany’s HeidelbergCement. Today the company has three integrated cement plants with a total production capacity of 18.5Mt/yr.
Indocement’s most significant installation is the 11.3Mt/yr integrated mega-plant at Citeureup, which has an incredible nine dry kilns. It is complemented by two 2.6Mt/yr plants at Tarjun and Cirebon. As well as the integrated facilities, the company operates grinding and packaging plants. Of all of the plants, nine are located in Citeureup, Bogor in West Java, two are in Palimanan, Cirebon in West Java and one isin Tarjun, Kotabaru in South Kalimantan. Having marketed cement under the ‘TigaRoda’ brand since it started production, Indocement now offers OPC, CEM II, CEM III, oil-well cement and Portland composite cement. In 2005 Indocement differentiated itself from its local competition by becoming Indonesia’s only producer of white cement. The launch was successful and the supply of white cement now accounts for the majority of its cement sales. In 2010 Indocement installed new batching plants for its bulk cement and ready-mix concrete activities so that it could expand its market share away from its traditional Java base. Indocement also has minor aggregate activities.
Holcim Indonesia was founded as PT Semen Cibinong in 1971. It was renamed after being taken over by the Swiss cement giant Holcim in 2006 and now operates two integrated cement plants. These are located at Narogong and Cilacap, both of which are in Java. It also has a cement grinding station at Ciwanda inBanten. A third integrated plant is scheduled to begin operations in 2013 at Tuban in East Java. The company’s cement production capacity is currently 8.3Mt/yr although the Tuban plant will see this increase to 10Mt/yr in 2013.
As well as Semen Gresik, Indocement and Holcim Indonesia, there are also integrated cement plants operated by Semen Kupang, Semen Bosowa Maros, Semen Baturaja and Semen Andalas Indonesia (SAI). Between them, these plants have approximately 5.25 Mt/yr of cement production capacity.
