| Summary: | Infrastructure development and changes in a land-use change in Surabaya can cause unintentional changes in urban climate. The change that can be felt most directly is the change in air temperature which increases. This increase in air temperature results in the formation of Urban Heat Island. Besides, an increase in temperature can affect the level of comfort in an area. This study uses Landsat 8 satellite imagery data to see the effect of land cover on the distribution pattern and intensity of urban heat island in Surabaya. Also, the Temperature Humidity Index (THI) is used to measure the comfort level in Surabaya.
The results of Landsat 8 satellite image processing show that most land cover changes occur in two Surabaya and surrounding areas is the change in vegetation land cover and vacant land into built space. Land cover for built space has increased by 14% in five years. Besides, there was an increase in the intensity of urban heat island in the period 2013-2017. Areas that have strong urban heat island intensity are in the area of Central Surabaya, North Surabaya, and South Surabaya and spread to the Sidoarjo Regency. Areas that have a strong urban heat island intensity, have more dominant built space land cover. The level of comfort in Surabaya shows a decrease in the level of comfort in the 2013-2017 period. The area that has a low level of comfort (uncomfortable) extends from 2013 to 2017 amounting to 6,913.21 ha.
