Abstract

Urban Heat Island (UHI) merupakan fenomena suhu di daerah perkotaan yang lebih tinggi dibandingkan dengan daerah sekitarnya. Fenomena UHI sudah terjadi di kota-kota dunia termasuk Kota Surabaya. Konversi lahan tak terbangun menjadi lahan terbangun diduga menyebabkan fenomena UHI tersebut. Oleh karenanya penelitian ini dilakukan untuk mengetahui pengaruh tutupan lahan terhadap suhu permukaan Kota Surabaya.Untuk itu, penelitian ini menguji hubungan antara tutupan lahan, Normalized Difference Built-up Index (NDBI), Normalized Difference Vegetation Index (NDVI), dan Land Surface Temperature (LST) dari data citra landsat tahun 2001 dan 2015. Analisis korelasi dan regresi dilakukan untuk mengetahui hubungan antara tutupan lahan, NDBI, NDVI, dan LST. Hasil penelitian menunjukkan selama tahun 2001 hingga 2015 terjadi peningkatan rata-rata LST di Kota Surabaya sebesar 3 oC. Dibandingkan tahun 2001, wilayah sebaran suhu tinggi (> 30 oC) semakin meluas sekitar 19.523,61 Ha yang tersebar hampir ke seluruh wilayah Kota Surabaya di tahun 2015. Perluasan suhu tinggi tersebut sejalan dengan perluasan wilayah terbangun baik berupa permukiman maupun industri-pergudangan. Berdasarkan hasil analisis diketahui bahwa kenaikan LST secara signifikan dipengaruhi oleh NDBI, dengan koefisien determinasi (R2) sebesar 0,72 (tahun 2001) dan 0,653 (tahun 2015) ================================================================================ Urban Heat Island (UHI) is a global phenomenon where a city or a metropolitan area is significantly warmer than its surrounding rural area. Land conversion into a built-up area supposedly is one of the main cause of UHI phenomenon. The purpose of this research is to identify the impact of land cover change on Surabaya’s surface temperature by conducting a test to check the correlation between land cover, Normalized Difference Built-up Index (NDBI), Normalized Difference Vegetation Index (NDVI), dan Land Surface Temperature (LST) from landsat imagery data of 2001 and 2015 using correlation and regression analysis. The result shows that for fourteen years, between 2001 and 2015, LST in Surabaya has been increased for about 3 oC. Compared to 2001, in 2015, high-temperature area (> 30 oC) has been expanded for about 19.523,61 Ha in various locations in Surabaya. The increasing temperature is parallel with the built-up area expansion, both for industrial or housing necessities. According to the analysis, LST has been significantly affected by NDBI, with coefficient of determination (R2) is 0,72 (in 2001) and 0,653 (in 2015)
