Judul: Model Dinamika Sistem Penyerapan Emisi CO2 di Kota Bogor
Abstrak: Most of the urban pollution is the result of carbon dioxide (CO2) emission from human activities. Green city is a concept of handling these problems by including the environmental aspects in every urban activity. Bogor is one of the cities that have implemented that concept. This research identified CO2 absorption in Bogor and the alternatives to solve the emission problem. CO2 absorption system model was created using software Stella 9.0.2 based on loss – gain emission concept for 30 years prediction. Many urban activities are assumed to increase CO2 emission, while the decrease factor is green open spaces as CO2 sequester. Human activities that contribute to CO2 emission are transportation, industries, energy consumption such as fuel or electricity, house hold waste, and farms. The result of this research, the CO2 emission of Bogor reached 20 027 878 tons in 2042. Combined mitigation in several sectors could reduce CO2 emission by 2 797 667 tons. CO2 emission could be neutralized by reforestation in 2036.

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: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
