Judul: Aplikasi citra landsat dan sistem informasi geografis untuk mengetahui perubahan penutupan lahan serta suhu permukaan kota (studi kasus : kota Bandung tahun 1997, 2002, dan 2006)
Abstrak: Bandung Cit) has undergone land cover changes indicated by the enlargement of constructed areas. This caused on the decrease of Green Open Space (RTH) which lowered the beauty and comfol-t of the city due to increasing urban surface temperature. Remote sensing data is used to identify the changes on temperature distribution caused by land cover changes. While Geographic Infor~nation System is applied to gain precise spatial data in a short time. The purposes of this study are ( I ) to lcnow and analyze land cover changes in Bandung City year 1997, 2002, and 2006; (2) to know and analyze the distribution of surface temperature due to land cover changes in Bandung City year 1997, 2002 and 2006; and (3) to determine correlation between vegetated Nol-nzalized Diference Vegetation Index (NDVI) and urban surface temperature. The methods of the study include laboratory work and ground check. Processi~lgo f Landsat image TM and ETM used ERDAS Inzcigine 8.5. This work consisted of ( I ) data import. layer stacking, geometric correction, image cropping, land cover classification, and accuracy test for the res~~lotf land cover classification; (2) conversion of Band 6 into surface temperature and classification of urban surface temperature, analysis of land cover impact on the distribution of surface temperature in urban and rural areas; and (3) correlation between vegetated Nornznlized Dijfel-ence Vegetation Index (NDVI) and surface temperature.

Judul: Relationship Between Urban Green Space and Surface Temperature By Using Image LANDSAT TM/ETM+ (Region : DKI Jakarta)
Abstrak: Urban Green Space (RTH) is regions covered by different types of vegetation in order to support direct and indirect benefits for the comfort and well-being. Jakarta has a rapid land cover changes every year, and the increased activity of the city brought an indirect impact on climate in the component elements. RTH reduction affects climate elements, one of which is surface temperature. Surface temperature is strongly influenced by the conditions of closing its land because of the nature of emissivity and thermal conductivity. This study examines the relationship between green space and the surface temperature using remote sensing techniques of LANDSAT satellite in 1992, 1997, 1999, 2000, 2001, 2004, and 2006. The technique used to determine the value of green space that is a supervised classification of various types of closure land use channel 5, 4, 2 (RGB), and to determine the surface temperature is used channel 6 (thermal) by processing the spectral radiance values and the digital number. The area of green space in a row in 1992, 1997, 1999, 2000, 2001, 2004, and 2006, was 42.2%, 32.1%, 29.7%, 27.4%, 26.3%, 22.5%, and 19.3%. While the surface temperature values obtained by the RTB 29oC-42oC, 27oC-30oC RTH, and a body of water 17-26oC. Surface temperature is strongly influenced by the conditions of closing its land, so the reduction in green space contributes to an increase in surface temperature.
