Judul: Pemodelan hutan kota untuk ameliorasi iklim mikro di Kota Palu
Abstrak: Climate characteristic of Palu city is very specific, which is indicated by high air temperature and low precipitation. The objectives of research are : (1) to analyze the dynamics of changes in area and distribution of land cover types in Palu, (2) to analyze the relationships between dynamics of greenery open space area, temperature distribution, and the role and needs of urban forest to improve microclimate in Palu, (3) to develope dynamics model system of urban forest for micro climate amelioration, (4) to formulate policies that can be recommended for the development of urban forest in Palu. The research was carried out based on field survey, questionnaire, and expert judgement. GIS and Arcview approaches for spatial dynamic analysis, to develop dynamics model system of urban forest using program powersim studio expert 2005 version, to formulate policies that can be recommended for the development of the urban forest using policy analysis with AHP. The results obtained are: (1) for 13 years from 1997 up to 2010 was found that greenery open spaces have decreased from 80.4 % to 78.8 %, (2) the increasing greenery open spaces will decrease the maximum of air temperatur, significantly. The regression is Y = -0.1203 X + 39.51 with R2 = 0.503, (3) Based on the model simulation, it is predicted that the urban forest will be decreased in the future, (4) Base on results of AHP, it’s known that needs of settlement is the priority factor, government is the priority actor, environmental sustainability is the priority purpose and to improvement of regulation and the provision of green open spaces and plants were the priority strategy of development of the urban forest in Palu.

Judul: Evaluasi Hutan Kota Berdasarkan Fungsi Ameliorasi Iklim Mikro di Kota Semarang
Abstrak: City developments have an impact on increasing the conversion of green open spaces (GOS) to builded spaces. The reduction of GOS areas cause the increase of the air temperature in the atmosphere. One way to overcome that problems by urban forest development for micro climate improvement. The function of the urban forest will be felt if the selection of tree species fits with micro climate amelioration function. The objectives of this research were to (1) study the characteristic of urban forest which is effective for the micro climate amelioration, (2) evaluate the suitability of tree physical characters for the micro climate amelioration, and (3) determine the potention of shade trees for the micro climate amelioration. The result shows that urban forest which is effective for the micro climate amelioration have an canopy areas as much as 19927 m2 with 720 of trees. The trees at Tinjomoyo Recreational Forest, Krobokan Urban Forest, and Menteri Supeno Park have the suitability value at the range of 61–80%, while Beringin Park have the suitability value at the range of 41–60%. The value of Key Performance Indicator (KPI) shows that the very potention trees for micro climate amelioration were Albizia saman, Delonix regia, Ficus benjamina, Pterocarpus indicus, Swietenia mahagoni, and Terminalia catappa.
