Judul: Pengembangan Hutan Kota berdasarkan Distribusi Suhu Permukaan Kota Denpasar
Abstrak: Denpasar is capital city of Bali Province. Denpasar city has been developing due to its population growth and development in many sectors. This condition resulted in environmental problem especially surface temperature increase which creates uncomfortable condition. One of important component to create comfortable environment in the city is urban forest. Appropriate planning of Open Green Space is needed to lowering surface temperature. The aims of this study are as follows : (1) identify surface temperature distribution of various land covers in Denpasar, (2) identify surface temperature which is predicted by converting band 6 Landsat 7 ETM, (3) determine the alternative of urban forest type based on surface temperature distribution which appropriate to Denpasar spatial planning. This study was conducted in Denpasar. Materials that were used in this study consisted of image Landsat 7 ETM (Path 116 Row 066) taken on 15th October 2009, and administrative map of Denpasar. Data were processed using ArcGIS 9.3 and ERDAS Imagine 9.1 such as layer stack, geometric correction, subset image, image classification and accuracy test. Band 6 was used to determine surface temperature distribution. Denpasar was dominated by built up areas (49,45 %) out of 12.891,6 ha of its total area. Based on band 6 estimation, the highest surface temperature was 33-34 °C in barren land of South Denpasar Subdistrict (Sesetan), meanwhile the lowest surface temperature was 17,9 °C in mangrove area in South Denpasar District. The result showed that the highest surface temperature was 30 °C in the form of barren land, meanwhile the lowest was 27,89 °C in the form of dense vegetation space. Green Space in Denpasar in 2009 was 43,11% out of total area. Based on surface temperature distribution, there are some appropriate alternatives to develop urban forest. Urban forest type green belt, yard-park, green roof are appropriate in Developing area I that consists of security, industrial and recreational characteristics. Urban forest of park type is appropriate in Development area II, which has function as protection. Yard-park and green belt are appropriate in Developing area III that consists of settlements and and security. Garden city urban forest is appropriate in Developing area IV that consists of recreational characteristics. Urban forest type green belt along the arterial roads (solid line of vehicles) are appropriate in Developing area V that consists of security and recreational characteristics.

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 ?., ,
