Abstract

The necessity of sand gravel in the development is become larger along with the advance of economic and population growth. Baro river has big enough natural resources in the form of excavated materials such as sand and gravel. Because of that reason, the stock taking of sand and gravel materials is needed in Baro river to serve as reference for the Government about the potential of owned excavated materials. Study about the potential of excavated minerals in Baro river is done in the form of research such as surface geological mapping, geoelectric survey, test pit, measurements of potential spacious and volume, as well as economic analysis. From the above researches, the informations obtained are about the potential area of the minerals, the quality of sand – gravel materials through the laboratory test, and the economical feasibility.In the research location, there are found excavated materials in the form of sand – gravel with the potential area and volume that can be mined appropriated with the government regulation is about 2.997.319,15 m2. The volume of excavated materials is about 14.986.595 m3 with the depth of 5 meters. The result of laboratory test, the grain size is dominated by gravel and sand with the percentage of gravel is about 28,41% up to 66.53%, the percentage of sand is about 33.21% to 71,44%, and the percentage of silt and clay about 0.10% to 0.48%. According to loss angeles abrassion test, the maximum value is 43.70% and minimum value is 38,53%. As well as the results of soundness test, the maximum value is 0,239%, making the aggregate is very resistant to weathering process. In the economical analysis, the result of the NPV >0, BCR > 1, and IRR > MARR with the value about 7.5%, so that mean the location is recommended for mined economically.

Abstract

Meru Betiri National Park (TNMB) is a natural conservation area related to land use that impact on the environment. Land-use suitability with land capability is essential so that the impact of the geological environment that can occur can be reduced and controlled. The research aims to determine the aspects of environmental geology and zoning land capability for governance of TNMB. Geological aspects of the environmental order that support this research are morphology (slope), lithology, hydrogeology (river density), and land cover. Each aspect is a parameter in the Analytical Hierarchy Process (AHP) evaluation method. The weight of each parameter of the AHP evaluation result is 26% for slope, 19% for lithology, 11% for river density, and 44% for land cover. The result of overlay parameters yields a score of each zoning and is classified into 4 (four) zoning land capabilities for governance of TNMB. The land use zone for governance of TNMB is divided into high capability zones, medium capability, low capability, and very low capability. High and medium capability zones can be used as conservation of TNMB primary forests.
