Site Sebuku Tanjung Coal (STC), Kotabaru, South Kalimantan

Hillcon's capability is proven by its achievements to work on coal production in proportion of the RKAB targeted by the mining site owner. Initially this site was in the form of a sea island which later then is processed with a planned plan. STC site has created job opportunities with nearly 1,000 employees, of which 60% of the workers are local people. With major developments like this, STC is targeted to continue to increase in production so that in the future there will be more job opportunities.

Sebuku's RKAB was initially targeted at 1.8 million tons per year in 2020 which then increased to 3 million tons per year in 2021. To fulfill the commitment to achieve this RKAB value, Hillcon continues to add units of heavy equipment capacity to achieve the coal overburden mining target. By 2022, Hillcon will increase its target to 5 million tons per year.

As a form of trust by the Sebuku group, Hillcon also participated in a road construction project for PT Sebuku Sejaka Coal which located nearby of the STC site.


RKAB (Rancangan Kegiatan Belanja) is the minimum mineral production value that needs to be achieved per year. This figure is determined by the site owner taking into account the capacity of the mining contractor. If the number is improved, it means that the mining contractor's performance in the previous year was satisfactory.
