Abstract: Indonesia is one of the mineral rich developing countries in the world. Indonesia has a large quantity of mineral resources such as natural oil and gas, hard minerals (metallic, non metallic/industrial mineral, coal, and stone), because it is located in the Pacific ring of fire. Mineral and energy commodities have always been giving contribution to Gross Domestic Product (GDP) of Indonesia besides doing regional development, because of its potential mineral resources. Trade of mineral commodity aims is to gain from trade of mineral to increase economic growth through Balance of Trade (BOT). Mineral commodity markets have been volatile for a long time. The trends of mineral commodity prices have been fluctuated and recently it changed dramatically due to commodity prices to increase within only several years. The aims of this study are to comprehend recent contribution of mining sector to Indonesian economy 1990-2014 and to analyze forecasting of mineral commodity future prices until 2025. The price trends of commodity mineral is increasing from time to time, but sometimes decreasing because of world crisis, scarcity, and other problems in the world related to mining, trade, and relationship between countries, such as fundamentals matter, including long-run demand growth, technical change that opens up new sources of supply, changes that transform the operation of financial markets, and macro-economic shocks, etc. Mining sector contribute about 6-12% of Indonesian Gross Domestic Product and increasing from time to time. Contribution of mining includes trade of mineral commodity, regional development by companies, etc. It is shown that mining is important for Indonesian economy. Methodology applied in this paper is data analysis using dynamic commodity and macroeconomic models and forecast using linear and polynomial regression with its trend line.

Abstract: This article considers the temperature influence of pollution transportation base on the transportation model of pollution in groundwater to finish the article by using Macro and micro method, the combination of theoretical analysis, experimental research methods and numerical simulation. Established the transportation model for consider temperature and solved by soft of Femlab. The result shows that the more close to the pollution source, the concentration is larger, the farther away from the source of pollution; the concentration value is small, which is consistent with the trend of pollution in the general case. With the increase of temperature, the concentration of pollution increased, among them, the higher the temperature, the rising trend is more obvious, that the migration and diffusion of pollution in the role of temperature. The temperature could increase depth of pollution diffusion. The results will also provide theoretical guide and technological support for the sustainable development of Yunnan economy and ecology as well as for the future laboratory experiments.
