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: Potensi Pengembangan Hutan Kota Berdasarkan Distribusi Suhu Udara di Kota Palu
Abstrak: Pertumbuhan penduduk dan ekonomi mendorong peningkatan kebutuhan lahan di Kota Palu. Hal ini berdampak pada alih fungsi lahan bervegetasi menjadi lahan non vegetasi dan peningkatan suhu. Hutan kota adalah salah satu jenis ruang terbuka hijau yang dapat berperan dalam meredam suhu perkotaan.Tujuan penelitian ini adalah menentukan prioritas dan potensi lokasi pengembangan hutan kota berdasarkan distribusi suhu udara di Kota Palu. Citra Landat 8 OLI/TIRS dianalisis untuk mengetahui suhu udara, tutupan lahan dan nilai NDVI. Semua data diolah di perangkat lunak Arcmap versi 10.5. Prioritas dan potensi lokasi pengembangan hutan kota ditentukan melalui analisis tumpang susun data suhu udara, tutupan lahan, nilai NDVI dan RTRW Kota Palu. Prioritas pengembangan hutan kota terbagi ke dalam tiga kelas prioritas yaitu prioritas 1 seluas 6740,86 ha, prioritas 2 seluas 2743,78 ha dan priotas 3 seluas 20.695,04 ha. Prioritas 1 merupakan area-area yang paling direkomendasikan untuk dikembangkan menjadi hutan kota sebagaimana 98,31% dari luasnya bersuhu ?27,1 ?., Population and economic growth have driven an increase in land demand in Palu City. This causes the conversion of vegetated land to non-vegetated land and increasing temperatures. Urban forests are a type of green open space that can play a role in reducing urban temperatures. The aim of this research is to determine priorities and potential locations for urban forest development based on the distribution of air temperatures in Palu City. Landat 8 OLI/TIRS imagery was analyzed to determine air temperature, land cover and NDVI values. All data were processed in Arcmap software version 10.5. Priority and potential locations for urban forest development are determined through overlap analysis of the gathered data on air temperature, land cover, NDVI and Urban Land Use Plan of Palu City. Urban forest development priorities are divided into three priority classes, namely priority 1 covering an area of 6740.86 ha, priority 2 covering an area of 2743.78 ha and priority 3 covering an area of 20.695.04 ha. Priority 1 is the most recommended areas to be developed into urban forests as 98.31% of the area has a temperature of ?27.1 ?., ,
