Abstract

Mining industry provides benefits to the state in mining as a source of state revenue and foreign exchange earner, producing raw materials for the industrial, infrastructure and socio-economic facilities, and employment providers. Utilization of natural resources in openly coal mining in the forest did to get these benefits, but on the other hand cause environmental harm. Land clearing activities in coal mining, open forest vegetation is causing the loss of economic benefits of forest. Exploitation of coal caused the shrinking amount of coal (coal depletion). Although revegetation activities have been conducted on coal mined land, those would still cause harm to the environment. The research conducted at the site of coal mining PT Bukit Asam (PTBA) South Sumatra Indonesia using quantitative methods of Net Present Value (NPV) aims to assess the value of environmental damages incurred as a result of the utilization of natural resources in coal strip mine in forest areas. The calculation of forest benefit in and after the forest recovery period is using time dimensions that has innovated in this study. The results found for the environmentalloss duringlife of mine for a period of time 1997–2023 PV 2009 amounted to Rp 73.98 trillion,-

Highlights

Sound development becomes an important requirement for any nation that wants the preservation of natural resources
Value of forest loss is not taken into account only in the dimension of space, and with the calculation of time dimensions (15 years), adjusted to the time of recovery secondary forest logged over to approach its original state, and the mature eucalyptus plants are most abundant in the location Tambang Air Laya (TAL) PT Bukit Asam (PTBA) and can be extracted as eucalyptus oil, as well as the loss values for each component and forest benefits over the life of the mine and the benefits of forests to t years after the end of the forest restoration activities carried out calculations to obtain the present value of the total economic value as the novelty of this study are as follows: a
The calculation of forest benefit in and after the forest recovery period is using time dimensions has been innovated in this study

Summary

Introduction

Sound development becomes an important requirement for any nation that wants the preservation of natural resources. According to Reference [1] a lot of forest ecosystem services value clearly can not be known its monetary value The impact of these policies affect the forest use, including for open pit coal mining activities more consider the financially benefits, so that the rate of degradation become faster. Use of natural resources by open mining coal land clearing activities and coal exploitation activities pose a negative externality on the function of forest ecosystems, such as forests function as a provider of natural resources such as timber resources and coal resources contained in the forest The loss of this function results in loss of economic benefit to the forest so that the resulting loss of forest and coal depletion. In accordance with this study seem it necessary to assess economic losses of natural resources and the environment due to the use of natural resources in coal mines open in logged-over secondary forests on coal stock loss and the loss of value of the economic benefits of forests
