Penggunaan Penginderaan Jauh dan SIG untuk Mengetahui Perubahan Penutupan Lahan dan Kecukupan Ruang Terbuka Hijau sebagai Rosot Karbondioksida (Studi Kasus; Kota Bogor Tahun 1991, 2000, dan 2012)

Abstract

Bogor city is a residential as well as services city. The city have been experiencing land cover change, from nature to variety of infrastructure purpose. As a result, it will increase the air pollution especially CO2 in the atmosphere. One way that can be used to reduce level of air pollution is development of green open space in spatial planning in the city of Bogor. The results of the analysis of spatial and temporal Landsat imagery Bogor City area in 1991, 2000, and 2012 showed this land cover in general is dominated by sparse vegetation amounted to 3.221,09 hectares or 28,01%, 4.009,90 hectares or 34,86%, 4.114,36 hectares or 27,07%. Land cover changes during the two periods was decrease of agricultural land, sparse vegetation, shrubs, and open land. Meanwhile land cover the increase vegetation. The need for green space in the city of Bogor area could be determined by the approach of CO2 absorption. Based on the level of CO2 emissions in the city of Bogor need 29.770,25 hectares open space, the available open space only 4.040,28 hectares or 35,13%. The Bogor city need addition green open space approximately 25.729,97 hectares. Value of CO2 emissions in 2025 amounted to 61.103,38 Gg, so the vast green space required is 1.048.848,17 hectares of area assuming the actual circumstances in the field using image data 2012.
