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: 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
