- ABSTRACT Urban reforestation which emphasized the regreening of the non-building block open space is aimed at reducing air temperature, accelerating air-flow, absorbing solar radiation, absorbing air pollutant, increasing air moisture, and providing comfort, coolness and freshness for urban environment. This research which was conducted over the Urban Evergreen Open Space (Ruang Terbuka Hijau Kota) of Kudus Plaza Parking Garden and Tugu Identitas Garden areas, was aimed at studying the difference in microclimate condition and discomfort index based on canopy coverage and tree density, and to find out the capability of trees (vegetation) in reducing air temperature and increasing air moisture. The parameters measured in this study were: air temperature, air moisture, wind velocity, solar radiation, canopy coverage, tree density, tree height, and (three) density. An experimental method was applied for this research, where the sample of study was taken random by using a transect method. Variances analysis with a Completely Randomized Design followed with multiple and partial regressions. From the analysis result of a Completely Randomized Design, significant difference from microclimate elements (temperature, moisture, wind velocity, and solar radiation) and comfort level (implemented in discomfort index) was shown in both studies. The regression analysis showed significant effects of canopy thickness and coverage on air temperature and moisture. Whereas, the effect of tree height was not significant. Based on the results of study, it was concluded that the differences in tree densities and canopy coverage percentage would exert some effect on the condition of microclimate elements. In addition, the canopy thickness and coverage factors also influenced temperature change and air moisture. Keywords: urban evergreen open space, microclimate, discomfort index
