PENGARUH TATA HIJAU TERHADAP SUHU DAN KELEMBABAN RELATIF UDARA, PADA BALAI BESAR PENGEMBANGAN MEKANISASI PERTANIAN, SERPONG

Green Open Space on office area essential to be considered to create a comfortable environment. Greenery in BBP MEKTAN need to be improved to increase the climatological comfort, beside built area around. The Study aimed to asses the effect of canopy shape, distance from tree, and tree distance from building. This study also asses the relation between temperature and RH of green open space, and planning for BPP MEKTAN greenery for climatological comfort. The observation was conducted in the area of BBP MEKTAN. The observation was conducted from February to May 2013 in BPP MEKTAN. The Analysis of temperature and humidity was performed by varian analysis and middle value test. The result of this study showed that the shape of canopy affect the temperature and humidity, the crown around and round open decrease the average temperature about 2C and increase humidityabout 5%.he farther the distance from the tree, then the effect of a decrease in temperature and increase in humidity are decreasing. The closer the trees from the buildings and the wider canopy cover, result on a decreasing in temperature and an increasing in RH indoor Cover area of open green space associated with the temperature and humidity, the total area of open green space relationship with temperature. Planning of green open space in BBP MEKTAN was based on the results of previous study 1 and 2, that is conducted by addition of vegetation that provides shade effect in areas close to buildings, roads, and parking areas.

Analysis of Green Space Characteristic Effect to the Comfort Microclimate in the Simple Flats in Jakarta

Existence of green spaces on simple flats (Rusunawa), especially trees, greatly affect the ambient temperature outside and inside the building. Density of tree canopy can modify air temperature under trees or buildings by reducing solar radiation on building facade. The aims of this study is to analize the characteristics of green space in Rusunawa and its influence on the microclimate. The experiment was conducted at four Rusunawa building located in Jakarta, i.e. Rusunawa Jatirawasari, Tambora, Pulogebang, and Marunda Cluster A. Species and number of trees were identified, while the ground cover was identified by its species and coverage. Physical characteristics of trees were measured by tree thrunk, tree height, and width crown. Measurement of temperature, relative humidity (RH), and wind velocity was conducted at seven points in each Rusunawa to determine their effects. The results showed the presence of trees can modify the temperature of building outside similar with in the building. The decrease of temperature was influenced by green coverage area, green coverage index, and environmental condition around Simple flats. In this study, the best microclimate was modification by the ability to reduce largest temperature differences. Further more, green space in Rusunawa Marunda Cluster A was considered as the most effective one in reducing temperature.
