The Company’s policy to sustain the environmental preservation is reflected in various activities of PKBL program. In determining the PKBL program, every factory and sales area prioritizes the surrounding community’s basic needs such as religious, youth, and regional and national holiday activities. The Company implemented PKBL program after directly interacting with the surrounding community to determine the programs that are on target and needed by the community. A healthy and synergized working environment makes business activity can runs smoothly, and the Company achieves profit and grows and develops in accordance with determined target.


Corporate social responsibility in environmental field is held annually as the proof that the Company is willing to preserve and protect the nature. Activities performed such as trees-planting, waste management, environmental impact assessment.

Waste Management

During concrete making process, the Company produces production waste that is not dangerous and poisonous (B3 waste). Before dumping, the waste is first flowed to ponds to clean it from mud. The clean water from mud pool is flowed to the filtering, while the silt is used by the society for environment maintenance such as streets and embankment. The volume of silt used by the community in 2016 was 3,532 m3, while it was 92,179 m3 in 2015.The silt was used for strengthening the infrastructure as shown in the table below:

Environmental Impact Assessment (Amdal)

Periodically, the Company cooperates with external audit, to audit occupational safety management system in which it includes waste management. Up to date, waste produced by the company is liquid waste, which then is re processed to be utilized. If the re-processed waste is not utilized, the company gets rid of the waste in areas that have been determined beforehand. Concerning solid waste, the Company cooperates with local citizen to make use of the waste as ground cover. The waste can also be used to repair streets.

Regarding dust waste, its level is always maintained to be within the limit stipulated by the Environmental Impact Management Agency (BAPEDAL). The Company attempts to reduce dust waste by planting trees in location near the factory. Other than trees plantation and waste management, the Company complies with the rules stipulated by the Government, especially rules concerning environment. The Company seeks to be responsible by applying for permission in the form of UKL-UPL analysis of environmental impact. The following is permission granted to the Company concerning environmental field:

Utilization of Environmental-Friendly Energy and Material

The implementation of environmental-friendly green building concept is currently a rapid-growing trend in construction industry. One of essential parts in green building concept is the utilization of environmental- friendly construction materials, including concrete. The construction materials are drawn, produced, used, and maintained as minimum as possible to reduce damage to the environment. Concrete is composed of cement, sand, gravel, and water materials, as well as other additional materials to  achieved the desired quality. Several addition materials  contribute significantly in creating energy and waste, thus impact the environment. In the effort to reduce the negative impact of concrete production material, the Company has assessed and utilized the more environmental-friendly material and energy to produce concrete. They are:

  • Utilization of other materials, such as fly ash, hulk ash,  bagasse ash, metakaolin, and silica fume as pozzolan  that is able to reduce most of the use of cement;
  • Development of high quality concrete mix design, recycled material utilization, artificial material and  industry waste such as tailing, bottom ash, ferronickel, and glass as aggregate;
  • Development of bacteria-based self healing concrete, concrete that can heal itself by using bacteria;
  • Utilization of cement substitute material as basic bonding material such as alkali activated material and geopolymer, a material formed by using alkali activation on silica-alumina-rich basic material as the precursor.
