PT Saptaindra Sejati

As one of Indonesia’s leading mining contractors, PT Saptaindra Sejati (SIS) provides mining services and develops infrastructure and logistics for Adaro Indonesia and other customers.

With a heavy equipment fleet exceeding 1,300 units, SIS is among the largest mining contractors in Indonesia. This modern equipment fleet aids the company in ensuring that it maintains a competitive edge by continually improving productivity, utilization and efficiency.

SIS runs its business with a mission to provide sustainable excellence in mining services by ensuring high reliability and standard of occupational health, safety, and environment, with the support of competent human resources and proper technology. SIS offers an integrated mining service from coal extraction, coal hauling and overburden removal.


SIS is one of Indonesia’s leading mining contractors, providing mining services and infrastructure development and logistics services for AI, SCM and third-party customers.

In 2015, SIS removed 151.1Mbcm of overburden, 13% less than in 2014, and mined 29.5Mt of coal, down 3%. Adaro Indonesia remains SIS’s largest customer, accounting for 57% of SIS’s total overburden removal and 67% of its coal production.

For Adaro Indonesia, SIS removed 85.7Mbcm of overburden in 2015, down 24% year-on-year, and produced 19.6Mt of coal, down 7%. SIS also removed 5.5Mbcm of overburden at SCM mine in 2015 and produced 1.1Mt of coal.

SIS saw increases in its services for non-Adaro customers in 2015, with overburden removal for third-party customers 4% higher at 59.9Mbcm and coal production 7% higher at 8.7Mt. SIS’s Operational EBITDA was US$127 million, 7% higher than in 2014, and its net debt to Operational EBITDA ratio remained healthy at 1.4x.

At the end of 2015, SIS owned more than 1,300 units of heavy equipment, including 400-tonne excavators and 250-tonne haul trucks. SIS invested US$10 million in capital expenditure during the year for equipment maintenance and replacement of obsolete equipment.

SIS continually works to improve its services by applying the best technologies available to increase efficiencies, especially during the current difficult coal market condition. SIS extended its implementation of Jigsaw, a real-time fleet monitoring system, to maximize efficiencies and cost savings.

SIS has also obtained several international certificates for quality assurance, such as ISO 9001:2008 for quality management, OHSAS 18001:2007 for occupational health and safety management, and ISO 14001:2004 for environmental management.

Our History

PT Saptaindra Sejati started its business in 1991 as a small subcontractor for heavy equipment named Dianlia Setyamukti. The business developed and successfully became a mining contractor, and among the several first projects it was awarded were for PT Adaro Indonesia and PT Berau Coal.

In 2002, the shareholders and the management agreed to transfer all operational activities, consisting of staff and assets, gradually into PT Saptaindra Sejati (SIS). SIS was acquired by Adaro Energy in 2008.

Overburden removal and coal transportation are our main expertise. Through many years of working with a range of clients in differing conditions, we have gained a wealth of experience in the types of environment that characterize most mines in Indonesia.


Our workforce is trained and experienced in all required activities including planning, overburden removal, coal production and support activities needed to provide efficient mining. We use modern equipment and comply with all applicable safety standards.

With our well-maintained dump trucks and trailers, we can transfer coal efficiently from mining locations to ROM stockpiles and client shipping locations. We understand that every mining service is different and thus requires a specifically designed solution. SIS operates a different fleet for every hauling operation; this means that even for the most difficult areas coal can be hauled efficiently.

Moreover, SIS has adopted several cutting-edge mining technologies to improve the services; among these are using high-capacity machinery and adopting real-time tracking in fleet management. This system, adopted in 2010, uses micro-controllers for heavy equipment and Global Positioning System (GPS) technology to track the location and evaluate the performance of equipment on site.

SIS is also a leader in the use of dewatering technology, with material-breaking dredger pumps introduced in early 2011.

SIS is constantly striving to improve its services by applying the best technologies available to increase efficiencies, especially during the current difficult coal market condition.

SIS has implemented the “jigsaw system” technology, a real-time tracking method to maximize efficiencies and cost savings. It has also obtained several international certificates for quality assurance, such as ISO 9001:2008 for Quality Management System, OHSAS 18001:2007 for Occupational Health and Safety Management System, and ISO 14001:2004 for Environmental Management System.

PT Adaro Eksplorasi Indonesia

As a mining company, we must continually engage in exploration and expansion of our reserve and resource base. Organic growth is one of our key strategies and essential for our long-term goal of creating value from Indonesian coal.

PT Adaro Eksplorasi Indonesia (AEI) is charged with these activities not only at Adaro Indonesia but also across the rest of our coal properties in South Sumatra, East Kalimantan, and most recently in South Kalimantan at Balangan.


AEI annually reviews Adaro Energy’s resources and reserves by using the most recent drilling data and assumptions to provide an accurate assessment of the coal in the ground.

Adaro Energy Resources and Reserves are mostly reported according to the JORC Edition 2012.

For details of Adaro Energy’s coal quantity and quality at its various mine deposits, see Our Reserves and Resources.

PT Jasapower Indonesia

PT Jasapower Indonesia (JPI) is the owner of Adaro’s Out-of-Pit Overburden Crusher and Conveyor (OPCC). In order to combat rising haulage costs and reduce Adaro Indonesia’s dependence on fuel, we decided in 2010 to commence the mechanization of the mine with the installation of an OPCC system that will crush, transport and spread overburden to outlying dumping areas not practically accessible for overburden trucks.

Through an international tender process, we selected an international engineering company to design and construct the system, which consists of two 7,000 tonnes per hour (tph) crushing stations and a 12,000tph, 7.7km transport conveying system, including a 2.4km movable conveyor and mobile stacking and spreading conveyor.


Our subsidiary PT Makmur Sejahtera Wisesa (MSW) powers the OPCC from its 2x30MW coal-fired mine-mouth power station nearby. The use of coal-fired power reduces diesel fuel consumption and contribute to cost savings and efficiency.

The OPCC handled 8.56Mbcm of overburden in 2015. Along with the lengthening distance of the dumping area from the mine, the position of the OPCC’s spreading arm, the relocatable overland conveyor, was gradually extended by 384 meters, resulting in the distance from the crusher to the edge of the disposal area reaching 9,960 meters, compared to the 2014 average distance of 7,848 meters.

PT Adaro Mining Technologies

We established PT Adaro Mining Technologies in 2011 to focus on the research and development of coal upgrading techniques, coal gasification and coal liquefaction. Our goal is to optimize the use of coal reserves through developments in technology.

Coaltrade Services International Pte Ltd

Coaltrade Services International (CTI) is the coal sales agency handling Adaro’s exports to certain destination countries. CTI also trades coal from third parties and sells these to the export market. Its offices are based in Singapore.

In 2015, CTI’s total sales declined by 31% to 3.1Mt. Adaro accounted for 68% of CTI’s volume at 2.1Mt, 49% less than in 2014, while third-party customers accounted for 32% of volume at 1.0Mt, a 150% increase compared to 2014.
