      Abstract
      Pembangunan berbagai sektor di Kecamatan Cikampek menyebabkan perubahan tutupan lahan yang berdampak pada perubahan suhu permukaan dan suhu udara. Penelitian ini bertujuan untuk mengetahui dampak perubahan tutupan lahan selama tahun 1990-2020 terhadap suhu permukaan dan suhu udara Suhu permukaan didefinisikan sebagai suhu permukaan terluar suatu objek yang tergantung pada karakteristik fisik objek. Sementara itu, suhu udara adalah energi kinetik rata-rata dari pergerakan molekul-molekul udara. Nilai suhu udara diperoleh dari ekstraksi Land Surface Temperature (LST) dan pengukuran lapang. Hasil penelitian menunjukkan bahwa telah terjadi perubahan tutupan lahan di Kecamatan Cikampek yaitu peningkatan luas yang terjadi pada lahan terbangun dan penurunan luas lahan vegetasi. Perubahan tutupan lahan mengakibatkan peningkatan suhu permukaan yang berimplikasi pada peningkatan suhu udara. Suhu permukaan dan suhu udara memiliki korelasi positif yang kuat dengan koefisien korelasi sebesar 0,67. Suhu udara di Kecamatan Cikampek tahun 1990-2020 berada pada rentang 27,5°C hingga 29,3°C. Suhu udara memiliki nilai yang lebih tinggi pada lahan terbangun dan nilai yang lebih rendah pada lahan vegetasi.
       
      The development of various sectors in Cikampek District causes changes in land cover which have an impact on changes in surface temperature and air temperature. This study aims to determine the impact of land cover change during 1990-2020 on surface temperature and air temperature. Surface temperature is defined as the temperature of an object’s outer surface which depends on the physical characteristics of the object. Meanwhile, air temperature is the average kinetic energy of the movement of air molecules. Air temperature values are obtained from Land Surface Temperature (LST) extraction and field measurements. The results showed that there has been a change in land cover in Cikampek District, either an increase in the area that occurs on built-up land or a decrease in the area of vegetation. Changes in land cover result in an increase in surface temperature which has implications for an increase in air temperature. Surface temperature and air temperature have a strong positive correlation with a correlation coefficient is 0,67. The air temperature in Cikampek District in 1990-2020 has a value in the range of 27.5°C to 29.3°C. The air temperature has a higher value on built-up land and the lower value on vegetation land.
