Land use and cover (LUC) changes are one of the main factors in global environmental change. It directly affects the welfare of society through changes in environmental conditions, such as land degradation and ecosystem services value (ESV). These ecosystem services have a large impact on quality of life in urban areas in the highlands, such as the region of Takengon, and must be addressed in land use planning. The purpose of this study is to identify the impact of LUC on ESV in 2009 and 2014.Both LUC maps divided into four categories, namely built-up area, water body, forest, and non built-up area, using the ArcGIS ® 10.1, with a supervised classification. Furthermore, an assessment of several environmental service variables was carried out, namely gas regulation, water supply, waste treatment, food production, raw material, and recreation. The classification results show that the LUC2009 and LUC 2014 were dominated by forests, with 10,064 ha of forest in 2009 and 8,959 ha of forest in 2014. The decrease in forest area from 2009 to 2014 also reduced the ESV by 12.33%. The government needs to consider landscape conservation and sustainable urban development planning.
