Adaro Services

Adaro Services pillar was established 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. The companies under this pillar continuously develop expertise in their respective field and serve mostly the coal mining companies within the Adaro Group, while actively building relationships with third party customers to expand market shares.

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.

In 2020, SIS’ performance was affected by the pandemic COVID-19. The declining coal price drove SIS’s customer decisions to reduce both coal production and overburden removal activities. During 2020, SIS achieved overburden removal volume of 163.27 Mbcm, a decline of 29% y-o-y compared to 2019. SIS’s coal production volume in 2020 also declined by 16% y-o-y to 41.48 Mt. SIS’s customers, both from the Adaro Group as well as third party, lowered overburden removal and coal production volume due to the challenging coal market condition in 2020. On top of that, prolonged wet weather in 2020 posed a challenge for SIS to recover its overburden removal and production volume.

At the end of 2020, SIS owned more than 2,000 units of heavy equipment, including 400-tonne class face shovels and excavators, 200-tonne capacity of dump truck. SIS managed to maintain 94% physical availability of its equipment, above the standard operational parameter, and 55% utilization availability. In addition, SIS recognizes that to meet its future growth targets it has to continuously develop the competence of its workforce of 3,740 operators, 1,268 mechanics, 117 engineers, 460 administration and 1,720 management staff. In 2020, SIS continued to conduct integrated hard skill (technical) and soft skill (managerial) trainings, which were necessary to ensure satisfactory and on-time project deliveries.

In 2020, SIS maintained a strong safety performance throughout the year. SIS achieved LTIFR of 0.08 and SR of 7.50, and received Utama Award from the Ministry of Energy and Mineral Resources for standardization management and mining service business for mineral and coal.

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.

With its 1,300-strong fleet of heavy mining and support equipment, SIS has a continual flow of machinery that is surplus to requirement through being replaced by newer or upgraded units.

We have recently begun offering for sale good-quality used units and have a supply of approximately 30 units available for sale at any one time, including dump trucks, excavators, articulated trucks, dozers, motor graders and others.

PT Adaro Jasabara Indonesia

During 2020 Adaro Jasabara Indonesia (AJI) continued to provide a wide range of mining related services to AE’s coal assets and subsidiaries. AJI has four main practice areas: mining infrastructure engineering, mining facilities engineering, strategic planning including water management, and geological services, each of which makes up a division in the company. The technical teams are backed by our Support Services Department.

The Strategic Planning team provided added value studies to Adaro Indonesia, Adaro MetCoal, Balangan Coal and Mustika Indah Permai. AJI’s In-depth, strategic studies help the individual companies and AE make critical business decisions. The Strategic Planning team has either estimated or assisted in estimating coal reserves and coal resources for most of AE’s coal assets. Another vital service area for Strategic planning is water management.

The Geological Services team covers geotechnical services, field exploration management, drilling, and geological studies. The Geological Services Division also managed exploration projects for Balangan Coal (LSA and PCS) and AJI’s Geotechnical expert has provided reviews and advice for a range of mining and civil projects for AE’s coal assets. The Geological Services Division has the geological modeling expertise to provide new and updated estimates of coal resources for most of AE’s coal assets.

Coaltrade Services International Pte Ltd

Coaltrade Services International Pte. Ltd. (CTI) is AE’s subsidiary mainly operates as a coal trader, marketing agent, and coal terminal service agent from its office in Singapore. By providing agency services to the Adaro Group, CTI takes a strategic role by giving the group the access to the international marketing networks and keeping an eagle eye on the global and regional trends of coal production, supply, demand and pricing.

Apart from serving Adaro Group as its main client, CTI makes continuous efforts to expand its network in the global coal market, especially within the global metallurgical coal market. In 2020, CTI’s sales of coal purchased from third party decreased to 0.16 Mt from 1.24 Mt in 2019. Low electricity demand due to COVID-19 pandemic had negatively impacted the global coal market demand. However, the growth potentials in Asia’s coal trades post pandemic are expected to bring a positive impact to CTI’s trading volume and activities, thus generating higher revenue contribution to the Adaro Group in the coming years.
