THE EFFECT OF VEGETATION EXISTENCE AS CLIMATE ADAPTATION IN THE OLD CITY OF SEMARANG

Abstract

The increase in air temperature, which is quite extreme due to climate change, causes the comfort level of outdoor activities to be increasingly disturbed. Various efforts have been made to overcome the increase in air temperature by creating a greener environment and providing vegetation. This study aims to produce a pattern of vegetation distribution and its effect on the climate for decreasing outdoor air temperature in the Old City of Semarang, Indonesia. The data used in this study are primary in the form of air temperature data at 09.30 WIB and data on regional vegetation conditions at four stations. Secondary data is also used, mainly in real-time monitoring of regional activities on CCTV Online media owned by the Semarang City government. The data analysis method uses GIS and Ecotec-based spatial simulations and descriptive statistical data analysis methods to obtain vegetation distribution patterns and characteristics. The result is that the presence of vegetation as much as 5% of the total land area is still less influential in reducing air temperature due to climate change. The difference between this research and previous research is that it is located in a cultural heritage area. It requires special attention in providing vegetation so as not to damage the physical structure of the building. This study also found that the density of human activities around the vegetation site can inhibit microclimate modification. The vegetation coverage factor greatly affects the microclimate produced in the surrounding area.
