Abstract

This research is to see the impact of coal mining activities between before and after the rise of coal mining; since the Regional Autonomy Regulation executed to the latest conditions, based on the hydrological behavior of the Batang Ombilin Catchment in Sawahlunto. The Batang Ombilin Catchment is one of the significant drains in Sawahlunto with 2215 km2 of its area. Henceforth, this research focus is only on the analysis of ten sub-catchments with area 348.42 km2 of 2215 km2 total of the catchment area that they contribute significantly to the catchment. This research uses Land cover data from Landsat images of the United States Geological Survey (USGS) Earth Explorer. Henceforward, the Interpretation used is Guided Interpretation with the Maximum Likelihood method. This such Interpretation is to ease the distinction of vegetated lands classification (i.e., densely vegetated land, sparsely vegetated land (bare), and open land; due to rivers, housing, gardens, fields, and mining areas). The research results that changes in government regulations have a significant impact on the growth of the mining industry in Sawahlunto, which is direct, impacted the land utilization to the mining industry utilization for years. The regulations also guide the behavior of the people involved in the mining industry of the land utilization management directly. This indication based on the decrease of the land utilized for the open area that the mining industry boomed after the reclamation went through. In short, the change in land utilization has a direct impact on hydrological behavior.
