This research was made not only to find out scope of green area and total of carbondioxide?s emission in Palangka Raya which can be absorbed by vegetation but also to findout suitability of land use of green area of Palangka Raya with necessity of green openspace in Palangka Raya. The research was a description about environment condition inPalangka Raya which related to total of carbon dioxide?s emission and scope of vegetatedland. The result of the research based on analysis of land cover and carbon dioxideabsorption showed that scope of vegetated land in Palangka Raya was 219.498.7 hectaresand it was still able to absorb all carbon dioxide?s emission amount to 387.366,248 tonswhich came from energy consumption and respiration of Palangka Raya?s inhabitants.Based on the extent of its region, urban area of Palangka Raya needed green open space(RTH) with wide to 14.096,1 hectares, based on the number of inhabitants was needed581,84 hectares RTH which consisted of city park, city forest, median, river border andcemetery, based on equality of water use was needed 323,75 hectares RTH and based oncarbon dioxide?s emission was needed 3.331,38 ha RTH. Based on suitability plan of landuse of green area in urban area of Palangka Raya, there was lack of green open space. Subdistrict Pahandut lack of RTH based on extent of its district (-3.513,23 hectares), number ofinhabitants (-244,85 hectares), need of water (-142,45 hectares) and carbon dioxide?semission (-2.368,88 hectares) while sub district Jekan Raya lack of RTH based on extent ofits district (-9.071,96 hectares) and carbon dioxide?s emission (-5.660,93 hectares).Penelitian ini bertujuan untuk mengetahui luas kawasan hijau dan jumlah emisikarbondioksida yang mampu diserap oleh vegetasi serta untuk mengetahui kesesuaian tataruang kawasan hijau Kota Palangka Raya dengan kebutuhan ruang terbuka hijau KotaPalangka Raya. Penelitian berupa deskripsi tentang keadaan lingkungan di Kota PalangkaRaya yang berkaitan dengan jumlah emisi karbondioksida dan luas lahan bervegetasi.Hasil penelitian menunjukkan bahwa berdasarkan analisis tutupan lahan dan serapankarbondioksida, diketahui luas lahan bervegetasi di Kota Palangka Raya adalah 219.498,7ha dan masih mampu menyerap seluruh emisi karbondioksida sejumlah 387.366,248 tonyang berasal dari konsumsi energi dan respirasi penduduk Kota Palangka Raya.Berdasarkan luas wilayah, kawasan perkotaan Kota Palangka Raya memerlukan RTHseluas 14.096,1 ha, berdasarkan jumlah penduduk diperlukan 581,84 ha RTH yang berupataman kota, hutan kota, jalur hijau jalan, sempadan sungai dan pemakaman, berdasarkankesetaraan penggunaan air diperlukan 323,75 ha RTH dan berdasarkan emisi karbondioksida diperlukan 3.331,38 ha RTH. Berdasarkan kesesuaian rencana tata ruanghijau kawasan perkotaan Kota Palangka Raya, diperoleh adanya kekurangan RTH.Kecamatan Pahandut kekurangan RTH berdasarkan luas wilayah (-3.513,23 ha), jumlahpenduduk (-244,85 ha), kebutuhan air (-142,45 ha) dan emisi karbondioksida (-2.368,88 ha),sedangkan Kecamatan Jekan Raya kekurangan RTH berdasarkan luas wilayah (-8.936,96ha) dan emisi karbondioksida (-2.849,04 ha). |
