The Impact of Green Open Spaces Changes on Temperature and Humidity and the Livable City Index of Banda Aceh

Abstract

Construction of physical infrastructure resulted in reducing vegetation cover land. This problem has an impact on weather conditions, namely temperature and humidity, and the index of comfort for the citizens of the city. This study aims to find out (1) Changes in Open Space City of Banda Aceh for five years, from 2012 - 2017; (2) the connection between temperature and RTH relative humidity; (3) Comfort index based on the Temperature Humadity Index (THI) in the city of Banda Aceh; and (4) Comfort index based on the adequacy of green open space. The research method uses a quantitative approach. Sources of research data are Landsat Remote Sensing imagery and field measurements for temperature and humidity data. Data is processed by using GIS, product moment correlation analysis, determine the comfort index using the Temperature Humadity Index (THI) formula. Additionally, based on the results of data processing, it was concluded that (1) there was a reduction in green open space of 299 ha for five years in Banda Aceh, only Syiah Kuala District had a proportional open space area; (2) The correlation coefficient between temperature and relative humidity is -0.78 or in the strong category; (3) Comfort index based on THI Banda Aceh in the uncomfortable category; and (4) the lowest RTH with THI is 28.1 in Hutan Kota Trembesi, Jaya Baru District, while the highest THI RTH is 30.8 in Blang Padang Field, Baiturrahman District.
