IMPLEMENTATION OF BIOTECHNOLOGY IN INCREASING THE ENVIRONMENTAL SUPPORTING CAPACITY OF EX-COAL MINING SOIL

Abstract

Indonesia is a country that is rich in minerals and coal. Its management must provide real added value to the national economy to achieve prosperity and welfare of the people in a just manner. In this mineral and coal management, it is necessary to have supervisory authority to achieve the management objectives. Supervision of environmental management, reclamation, and post-mining must be carried out with the principles of good mining techniques to create a sustainable life for the environment. The purpose of this research is to apply appropriate and effective biotechnology methods in increasing the carrying capacity of the environment based on parameters of soil fertility, green plant growth, review of biotic and abiotic environmental influences and their effects on the social environment, cultural life of the community which in this case refers to economic factors. Based on the results of the research, it can be concluded that Cattle Rumen Microorganisms increase the carrying capacity of the soil of ex-coal mining land by improving soil nutrients with evidence from the research results, namely: increased plant height, increased number of plant leaves, and development of root nodules Tarum Nuts (Indigofera sp.)
