jailcd2020086: Tangerang as Urban Dense Area: Its Contribution on Micro Climate and Thermal Perception

Abstract

Development activities in high-density populated city of Tangerang have a direct impact on the area of conversion of vegetation land to non-vegetation land. In 2015, the area of agricultural land decreased from 37 million hectares from 2010 and the existence of these building structure, shape, and orientation of towering buildings in Tangerang causes more heat or heat reception because it has broader areas of reflection or absorption of solar radiation that causes an increase in temperature, led to Urban Heat Island phenomenon. This research aims to determine the condition of the microclimate in high-density urban environment through the evaluation of Tmrt (Mean Radian Temperature). The measurement of air temperature (Ta), humidity (Rh). and wind speed (V) connected to the thermal perception and related to human well-being shown by PETl (Psychologically Equivalent Temperature), thermal index derived from the human energy balance, in four districts; Neglasari, Jatiuwung, Periuk, and Cipondoh were measured in January 16th with four spots per each district. The evaluations of thermal comfort related to human The final result shows that Jatiuwung sub-district had the highest PET value of 51.5° with 32.6°C, 63.2%, 0. 1m/s exceeding the 'Very Hot' sensation. The research also shows that there are no regions that have PET values below 41.1', which is included in the 'Hot' sensation.
