Adaro Services

Adaro’s Services pillar aims to streamline all of the mining service providers within Adaro Group. This pillar focuses on providing high quality support services to the mining industry from exploration, engineering and technical, to contracting and lastly marketing and trading. Main customers of this pillar are coal mining companies from within the Adaro Group as well as from outside the group.

PT Saptaindra Sejati

PT Saptaindra Sejati (SIS) is one of Indonesia’s largest mining contractors. The company provides broad range of services covering contract mining, mine planning, civil work, infrastructure development, land logistic and reclamation of mining area. As its services are exposed to customers involved in the coal mining sector, SIS’s production volume performance can be directly impacted by the volatility of coal price.

As coal prices started to decline in 2019, SIS’s strategy of focusing on internal growth allowed SIS to weather the downturn supported by Adaro Group’s increased coal production. SIS recorded capital expenditure of US$155 million mainly to acquire and replace production equipment in support of increased operational activities. At the end of 2019, SIS owned more than 2,000 units of heavy equipment, including 400-tonne class face shovels and excavators and 200-tonne capacity dump trucks. SIS managed to maintain 91% physical availability of its equipment, above the standard operational parameter, and 61% utilization availability.

Despite coal industry’s downturn, SIS recorded solid operations in 2019, with overburden removal volume increasing by 5% to reach 231,0 Mbcm in 2019 while coal production increased by 10% to 49,2 Mt. The higher volume came from both coal mining companies under the Adaro Group and third party customers, resulting in a y-o-y increase in revenue of 5% in 2019.

To maintain SIS’s operational excellence and to meet its future growth target, SIS needs to continuously develop the competence of its workforce of 9,063 operators, mechanics, maintenance personnel, engineers, and administration and management staff. In 2019, SIS continued to conduct integrated hard skill (technical) and soft skill (managerial) trainings, which were necessary to ensure satisfactory and on-time project deliveries. This is especially important as SIS takes on new challenge to develop a new mining project within the Adaro Group, PT Maruwai Coal in Central Kalimantan.

SIS is committed to partner with its customers and be the preferred mining contractor and continues to deliver projects on time, within budget, incident free and in an environmentally sustainable manner that is in harmony with the local community. This is evidenced in SIS’s strong safety performance throughout the year. SIS achieved LTIFR of 0.05 and SR of 5.8, and has obtained several awards from the Ministry of Manpower and from the Governor of South Kalimantan.

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.
