The diversity of natural resources owned by Indonesia is a challenge for the
government in managing its natural products so that they can be utilized by the Indonesian people. Humans as the rulers of the environment have a very important
role in preserving the environment they occupy. Much of the damage caused by
human actions cannot be accounted for. Excessive use of nature has a major impact
on the environment due to waste. One of them is tailings waste which is the result
of mining activities of PT Freeport, a mineral mining company affiliated with
mining and processing ore to produce concentrate containing copper, gold and
silver. PT Freeport's mining activities have negative impacts that are detrimental
to the community and the environment. Mining activities are also not in accordance
with mining principles and legal regulations related to applicable environmental
laws and environmental pollution laws. This is what makes PT Freeport carry out
environmental conservation and community programs as a form of its
responsibility. The use of tailings as a raw material for concrete mixtures for the
manufacture and development of infrastructure in districts and provinces continues
to be carried out with the aim of reducing the negative impact of these tailings.
However, the constraints in the use of tailings are due to the fact that the tailings
qualify into the B3 class which cannot be utilized by the community and the
environment.
