Bachelor : Surface Temperature Distribution for Consideration of Green Space Development in Sidoarjo Regency


Under supervision : Lilik B.Prasetyo & Badriyah Rushayati

Sidoarjo Regency had an advantage economic development due to its location bordered  to Surabaya City. The increased space requirement for trade & industrial area forced  to green space conversion., resulted in temperature increase.  Research aims is to evaluate  and build the relationship models between the green space distance with surface temperature and provide an alternative green space development in Sidoarjo Regency.

To achieve this goal  remote sensing data of  Landsat 7 ETM were used. Satellite image processing is done to determine the land cover classification and surface temperature estimation in Sidoarjo Regency. Sample points  for  regression analysis were determined manually, on the buil-up areas. Distance the points to each land cover types (grass and bush, rice field, farm, close vegetation and sparse vegetation ) were made based on Eucledian Distance.

The regression result was presented in the formula below.

y = 28,7 + 0,00348 x1 + 0,593 Ln x2 + 0,565 Ln x3


where x1 is a distance of observation point to grass and bush, x2 is a distance of observation point to farm and x3 is a distance of observation point to rare vegetation.

Based the above equation,  close vegetation does not affect significantly to surface temperature because its area was very small.  Alternative green space development  should be done on location with a high surface temperature, namely : area is around PT Tjiwi Kimia, Sidoarjo and Waru district, Krian-Tarik by pass roads, and roads around the area of  Porong mudflow.



Green space development at Sidoarjo Regency could  be also promoted by planting trees, creating a vertical garden on home yard, planting and enriching the river border green space, planting and enriching green space of roads and creating a vertical garden at the office or industrial site.
