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