| Summary: | Indonesian coal production is expected to be increase in future due to rising
demand for development. However, coal mining has potential to cause negative
impacts on the environment, both in open pit or underground. Therefore, it is
important to maintain a balance between environmental concerns and priorities of
economic and social development. To monitor the effect of mining on the
environment, the company carries out observations regularly. As the time goes by,
this data will be more and more that require a database system to manage it. These
data generally have a spatial component, so can be visualized on map. Geographic
information system (GIS) has the ability to meet the needs of the above.
This study aims to develop an acid mine drainage (AMD) management model on
GIS using Phyton 2.51 and model builder facility. With the integration of
environmental observation data, environmental analysis, and presentation of
spatial data, GIS developed into DSS. In addition to providing information for
decision makers, the DSS also serves to bridge the various divisions involved in
the process of AMD management so that more efficient. This study uses
watershed approach to identify critical areas, so the management of AMD is more
focused on the area.
This research focused on Ukud catchment in coal mining Lati area, PT. Berau
Coal. There are three groups of regions that have a large influence of pollutant
load on the quality of river flow, namely the A1, A8, and A10, with pH
respectively 3,96, 4,26, and 4,17 and contain dissolved metal over the standard of
quality on Kepmen LH.113/2003. This group requires special attention
considering the effort needed to raise pH and lower dissolved metal content is
quite difficult and expensive. |
