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.

Abstrak: Greenery open space is a fundamental part of urban development and management in sustaining the quality of urban environment and the welfare of urban dwellers. A high rate of population growth and limited land owned causing the growth of physical development in the city is done by converting such green open space, agricultural land, forest and other open space for urban development purposes. This study is intended to analyze total value of greenery open space ecological benefits of Bogor City, and provide possible recommendations in order to increase the capacity of its urban ecosystem. This analytical framework is applied to Bogor City considering its peculiarities of greenery open space existence and architectures. The research was conducted by spatial approach through CITYGreen 5.4 software to determine the ecological benefits of greenery open space, based on the trees canopy cover and non trees canopy cover to predict the economic value. CityGreen is a software tool developed by American Forest that helps people understand the value of trees to the local environment. The result showed that CITYGreen 5.4 software can be used to conduct complex analysis of ecosystem services and create easy to understand reports.The software calculate dollar benefits for the services provided by the trees and other greenery open space in absorbed such harmfull pollutants, carbon storage and sequestration, and reducing storm water volumes as natural flood control. The capacity of ecological benefit can still be improved to provide greater benefits in various ways. This software will be very beneficial for city planners in evaluate site plan, and model development scenario that capture the benefits of trees.

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.
