Judul: 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)
Abstrak: 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.

Judul: Projection of Bogor City Green Open Space Area and Spatial Distribution Pattern Requirement
Abstrak: A growing number of inhabitant of the Bogor City increase urban space requirements, this broad impact on the reduction of green open spaces (greenery) yearly. Proportion of greenery in accordance with National Act No. 26 of 2007 on spatial planning in urban areas, representing 30% of the city area. Bogor occupies 11.850 ha, and need as consisting of 20% of city areas (± 2.370 ha) public green open space and 10% private green open space (±1.185 ha). In the next year, to avoid land-use change with green open space becomes more awake, it is needed to find the method to justify the priority of green open space to be conserved. This study calculated the appropriate green space to meet the needs of the urban population and total oxygen demand of the city. Calculation of the projected need for green space based on population was conducted by using population data and timeseries population projection in the year to be calculated. Calculation the need for green open space based on oxygen requirement was conducted by employing population data, number of livestock, the number of motor vehicles and the number of industries located in Bogor City, where the unit of analysis was per sub district. Estimated population of Bogor City in 2030 will be 1.428.488 inhabitants, and need greenery as much as 361,4 ha. Details of projected population and the need for green spaces as follows: (1) South Bogor Sub District, 269.070 inhabitants and 68,07 ha; (2) East Bogor, 151.362 inhabitants and 38,29 ha; (3) North Bogor, 238.372 inhabitants and 60,31 ha; (4) Central Bogor, 115.449 inhabitants and 29,21 ha; (5) West Bogor, 371.615 inhabitants and 94,02 ha; and (6) Tanah Sareal, 282.620 inhabitants and 71,50 ha. The projected requirements for greenery in accordance with the requirements of oxygen is 943,73 ha. It is distributed to South Bogor district 188,65 ha, East Bogor Areas 94,38 ha, North Bogor area 169,85 ha, Central Bogor area 103,71 ha, West Bogor 207,76 ha, Tanah Sareal area 179,39 ha. The final result of this research is a map of the direction and the distribution of green space in each district in Bogor City, where distribution is based on existing land use, with emphasis on the use of land with a low value of land rent, namely vacant land, shrubs and trees.

Judul: Karakteristik Anatomi Skelet Tubuh Buaya Senyulong (Tomistoma schlegelii)
Abstrak: Buaya senyulong (Tomistoma schlegelii) merupakan buaya besar yang rentan punah dan hanya dapat ditemukan di rawa dataran rendah, danau dan sungai di Sumatera bagian timur, Kalimantan dan Jawa Barat (Indonesia), Serawak, Semenanjung Malaysia (Malaysia) serta Brunei Darussalam. Tujuan dari penelitian ini adalah mempelajari karakteristik anatomi skelet tubuh buaya senyulong yang dikaitkan dengan fungsi dan perilakunya. Penelitian ini menggunakan satu set preparat skelet tubuh buaya senyulong. Parameter penelitian meliputi pengamatan bentuk bagian skelet yang khas, mengukur panjang dan lebar tulang, serta dibandingkan dengan skelet tubuh jenis buaya lain, biawak air (Varanus salvator) maupun literatur yang terkait dengan sistem skelet tubuh hewan. Karakteristik anatomi skelet tubuh buaya senyulong relatif mirip pada jenis buaya lain. Beberapa karakteristik yang ditemukan yaitu, proatlas pada os atlas, os axis hanya memiliki zygapophysis caudalis, bagian lateral dari ossa vertebrae cervicales yang dilengkapi dengan cervical ribs, memiliki jumlah costae sternalis yang banyak, rangkaian ossa gastralia pada abdomen, ossa vertebrae lumbales memiliki zygapophysis cranialis dengan sudut >90o dari sumbu tubuh. Selain itu, os vertebrae caudalis I memiliki caput cranial dan caudal, ossa vertebrae caudales memiliki processus transversus yang semakin memendek ke arah caudal. Di medioventral tulang ini ditemukan ossa chevron dengan hemal arch sampai menjelang akhir ossa vertebrae caudalis. Skelet tubuh buaya senyulong memiliki hubungan yang kokoh dan kompak untuk menunjang fleksibilitas tubuh untuk berjalan, berenang dan berburu mangsa
