| dc.description.abstract | Urbanization and population growth are the main factors causing land conversion.
Cities with high population density will be at risk of experiencing decrease in
vegetation density (Normalized Different Vegetation Index) and increase surface
temperature (Land Surface Temperature) which impact on various lines of life,
especially the comfort due to heat. The availability of green open space in urban
areas is becoming rare thing due to the high land use change in urban areas. This
study aims to determine the effect of urban parks on changes in environmental
temperature in Binjai City and Medan City by utilizing remote sensing technology
and Landsat images combined with temperature analysis using buffer zones from
urban parks. Results show in Binjai City, found the highest LST in 29-32 class with
an area of 1.057,72 Ha 0r 11,18% of area, while highest NDVI in >0.6 class with
area 1.58 Ha or only 0.02% of the Binjai city. In Medan city, the highest LST in 31-
34 class covering 1,545.37 Ha or 5.510% of area, while the highest NDVI was in
the >0.6 class covering 0.60 Ha or only 0.002% of the Medan city area. The results
showed that the urban park influenced the temperature reduction up to 300 m buffer
distance. The results of statistical analysis include classical assumption test,
multiple linear regression and partial t-test obtained variable presence of
vegetation (NDVI) is inversely proportional to the increase in surface temperature
with an adjusted R square value of 0.627 | en_US |
