Sustainability for Management and Protection Tin Mining Environment

. Tin mining environment sustainability is an effort for the protection and management of the environment as a systematic and integrated include planning, utilization, control, maintenance, surveillance, and enforcement of the law. This effort was done as big as for the prosperity of the people. Development in the field of natural resources and the environment is an attempt to harness the natural resources for the prosperity of most of the people by remaining attentive to the preservation of the function and the balance of the environment, economic interests the local society and culture, as well as spatial harmony in effort attainment of sustainable development. The environment has supported limited environmental resources like tin mine. During the exploitation is done are not beyond the limits of resources support neighborhood then natural resources can be used sustainably in accordance carrying capacity, i.e. the ability of natural resources to support the life of all beings in the ecosystem on an ongoing basis.


Introduction
The term Sustainable Development or sustainable development is also called, is designed to transform the conventional development paradigm (for conventional development) into a better direction. Broadly speaking, the definition of sustainable development is defined as development that adheres to the principle of the fulfillment of the needs of today without compromising the interests of generations to come [1]. But, in fact, sustainable development is not only based on environmental issues but instead undertook to include the policy in the field of economic, social and environmental protection. When referring to the results of the meeting of the World Summit in New York in 2005, these three policies that have been mentioned above have an affinity with each other, besides that, the third pillar of the above is also a catalyst for the achievement of sustainable development [2]. In other words, with the creation of synergies between economic, social * Corresponding author: author@email.org policy and the protection of the environment, it will be created a controlled relationship (bearable), equitable, and the relationship that has a spirit of development, the achievement of synergies between these dimensions will create development that is sustainable or sustain [3]. Through this sustainable development, due to the negative impact of development with conventional methods in the form of environmental damage through the destruction of natural resources such as water, forests, as well as the massive exploitation the resulting mining damage Ecology, can be prevented.
The availability of natural resources in improving the development was very limited and uneven, while natural resource demand continues to increase, due to increased development to meet the needs of the population. The efforts of controlling the pollution and environmental damage, then, need to do development planning which is based on the principle of sustainable development. The principle of sustainable development is done by combining the capabilities of the environment, natural resources and technology into the development process to ensure this generation and future generations.

Tin Mining in Indonesia
Mining is one of the important sectors in the economy of Indonesia, especially in his role as a foreign exchange earner. The mining sector is composed of sub-sectors of the oil and gas, General mining and minerals C. Tin mining is one of the sub-sectors General mining has been done since the reign of the Netherlands East Indies in the 17th century to now [4] and is one of the sectors of the economy, the mainstay of Bangka Belitung Islands province. Development that is based on the extraction of natural resources such as mining of tin will ultimately be stalled when the lead reserves run out. According to the US Geological Survey year 2006, the measured reserves of Tin in Indonesia around 800.000 to 900.000 tons, of which the islands of Bangka Belitung is a major producer of Tin. The average production level of about 60.000 tons/year, or the equivalent of 90.000 tons/year of lead sand. According to the Industrial Technology Research Institute (ITRI), PT Timah Tbk (TINS) managed to record the performance is good enough where this achievement is measured from lead production tonnage results. It is characterized by the inclusion of large TINS in 10 best years of refined Tin produced 2017. Source : [5] In the fifties, tin had been the result of the second mining commodity after oil, which contributes to the revenue of the State. Although history tin mining has been going on for more than two hundred years, the potential lead resources still remain unanswered. The tin mining business ranging from exploration activities to ongoing, intensive marketing, even though the business activities have been lasting quite a long time in Indonesia. Tin mining activity still requires exploration for the discovery of new reserves, particularly offshore deposits. Resources and reserves that have been revealed have not represented the overall offshore deposits particularly located at a depth of more than 50 meters, as well as the potential for low levels with respect to price increases, become high potentially economic. Indonesia as the world's largest tin exporter has the opportunity to maintain or control the price of tin in the world market. This needs to be managed optimally to keep and protect the mining business activities in order to produce a contribution to a more optimal development.

Enviroment Management and Protection
Management used in minimizing the degradation of land, water, and vegetation through the use of early rehabilitation (restoration) and to other (reclamation), as well as the socialeconomic interests through planning, organizing, coordination, and controlling the tin resources which is carried out jointly with stakeholders. The term has been described as a general process of reclamation where the surface of the land recovered for allocation to another. Reclaiming is based on the principles of ecological recovery and integrated is called restoration. The restoration of the environment is basically intended to return towards the original ecosystem aspects of structure and function. Rehabilitation is the term used for the process ahead of the return to the original ecosystem, ecosystem by creating alternative towards the original ecosystem through replacement.
In 1. Protection of the quality of surface water, ground water, sea water, air, and soil, as well as on the basis of the standard quality raw or raw damage criteria of the environment in accordance with the provisions of regulation ; 2. Protection and restoration of biodiversity; 3. Guarantee against stability and security a heap of rocks and tailings pond, cover, landmines, and other man-made structures; 4. Utilization of landmines in accordance with the allocation; 5. Pay attention to the social values and local cultures; and 6. Protection against the quantity of groundwater in accordance with the provisions of the legislation.

Tin Mining Environment Sustainability
The mining sector is one of the sectors of economic activity in addition to its activities producing the production results of the mines, also raises the impact of land use and landscape damage which is difficult to be returned to its original form. The existence of the concept of green mining is expected to create a balanced relationship between the company, the mining community, and offender nature. Nevertheless, it is very difficult to make a choice between the exploitation of resources and the protection of the ecological environment [6].
Forms management of tin mining and environmental protection has been done can be seen from mining activities conducted by PT Timah in its annual report, namely through environmental policy by obeying all regulations and legislation covering related environmental management related to the company's business. As proof of the seriousness of the company in maintaining the balance of the environment, PT Timah has gained several certificates. Source : Annual Report (2017) In addition, PT Timah has also shown its commitment by setting up environmental management costs and post mine for environmental management and monitoring activities of the amount set in accordance the standards of financial accounting. The Company has allocated budget for Environmental management and monitoring activities of which the amount is determined as provision per weight unit of refined tin produced. adapted to the impact happened. In the year 2017, the company has set a work plan Social responsibility towards the development of social and the majority of the affected community at the company's business operations.

As a form of corporate responsibility towards the environment has been explored, the company has performed an action reclamation of the former mining location gradually. The company has a reclamation program made during the five year 2015-2019. In the year 2017, The company has been conducting the reclamation of the former exploration mine is as follows:

Conclusion
Tin mining can be done in order to economically benefit the State, employers and the community; social giving progress for society through the enhancement of human resources, health and social harmony; and in the environment can be maintained and properly managed not only to the current generation but also for generations to come.
