Judul: Pengoptimuman Ruang Terbuka Hijau dan Ruang Terbangun di Kota Bogor
Abstrak: Conversion of green open space to built space without planning will lead to the decrease of agricultural land and environmental degradation. The decrease in agricultural land and poor agricultural cropping patterns result in the reduction of food self-sufficiency ability of a region. It is therefore necessary to organize green open space and built space which supports food selfsufficiency program. This plan can be done using mathematical models. In this work we model the land use problem in the framework of a goal programming. The objective of this research is to optimize the built space, green open space, and agricultural cropping pattern in the City of Bogor. The program used to obtain the solution is LINGO 11.0. The optimal solution of the problem is expressed in term of optimum land use, optimum area of agricultural crops, deficit/surplus built space, deficit/surplus green open space, as well as the deficit/surplus consumption demand the fulfillment of local agricultural commodities. This information shows that the fulfillment built space and green open space target is achieved, while the target local consumption demand of farm crops is not reached. The results of this work can be utilized by the government of Bogor in determining land use policy.

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: 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.
