Abstract

Indonesia is a country rich in tin minerals. Indonesia has 17% of the world's total tin reserves but produces 26% in 2020. This shows an unequal value between income and expenditure. Therefore it is necessary to calculate tin resources on a regular basis so that their availability is maintained. Here, two methods of calculating the estimated tin resources are used, namely the inverse distance weighted (IDW) and nearest neighbor point (NNP) methods. The estimation results using both methods are tin resources using the IDW method of 1,501,300 tons while using the NNP method 1,270,222 tons. In conclusion, there is a difference in the estimation results using the two methods of 231,078 tons or 18%. This difference is caused by the working of the two methods, namely the principle IDW method considers several closest points, while the NNP method considers the closest point.

Abstract

Coal is one of the fuels sourced from solid hydrocarbons. Bataubara itself is formed from plants and microorganism that solidifies due to the influence of pressure. The use of coal as a fuel is widely used in large industries, such as the cement industry and in steam power plants. administratively the mining concession of PT. Bukit Asam, Tbk. is included in the Tanjung Enim City, South Sumatra Province. In July 2022, there was a torn Coal Conveyor-07 (CC-07) incident that disrupted productivity at TLS 2 (Train Loading Station) so that it could not deliver coal, causing losses to the company with a total of 42,562 tons. With a total loss of Rp. 28,372,329,681.
