Abstrak: Availability of Green Open Space in urban areas is decreasing and could result in environmental degradation. One form of environmental degradation particularly in the city of Bogor is the threatened habitat of Bats (Pteropus vampyrus) in Bogor Botanical Garden. Bats act as pollinators for the trees with high commercial value such as banana, durian, mangrove, kapok, mango and other types of other woods in mangrove forests. Biological diversity is increased by the pollen from the trees brought by the bats that flies long distances. In addition to these benefits, the presence of wildlife in urban environments bats also promises an interesting tourism attraction for tourists. Unfortunately, there is a recent declining population of bats, and it’s greatest threat is its’ habitat loss due to the reduction of food availability due to the decreasing of the existing green space. This study aims to plan a green open space based on an ecological approach to conservation of habitat of bats (Pteropus vampyrus) in the city of Bogor. From the analysis of green space, it can be concluded that the green space to the city of Bogor enrichment plant species like bats (with the architectural characteristics: an average height of 45-65 m, average trunk diameter of 50-95 cm, canopy width reaches 5-25 m and leaf density reached 10-75%) as a place to live that makes it easy to perch and fly. In addition the plant is the source of feed is a plant that produces honey / nectar, small amounts of pollen (pollen) and flowers in large quantities. Planning green open space as a supporter of wildlife conservation of bats (Pteropus vampyrus) follows the pattern of converging to the center of the City Park Botanical Garden in Bogor District Central. Botanical Gardens can be focused as a "home base" for wildlife bats. Green open space in Bogor City Planning must be integrated with urban planning. Other forms of green space in urban areas laid out so that continuous scale ranging from environment to form neighborhood parks and park districts. Then the green areas that have a relatively elongated shape (green line) as a connector or fastener parks and green space areas (node or district). Green open space this pathway may serve as a corridor for wildlife movement in any urban area. Protection of the green line (border river / electric transmission tower/ rail) needs to be done to protect the border functions of the human activities that can disrupt and damage the condition of securing it. Broad demarcation in the city of Bogor area of 1858.08 hectares, or approximately 15.51% of the total area.

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: Konversi Asam Oleat Menjadi 1-Hidroksietil-2-alkil-2-Imidazolina dengan Dipandu Kalorimetri Pemayaran Diferensial.
Abstrak: Suhu efektif untuk konversi asam oleat menjadi 1-hidroksietil-2-alkil-2-imidazolina (HEAI) perlu ditentukan karena berpengaruh pada kemurnian produk konversi. Pemantauan reaksi menggunakan analisis kalorimetri pemayaran diferensial merupakan salah satu solusi untuk memecahkan masalah ini. Tujuan penelitian ini adalah mendapatkan suhu yang efektif untuk memperoleh HEAI dengan kemurnian tinggi. Konversi dilakukan dengan memanaskan asam oleat dan aminoetiletanolamina (AEEA) menggunakan metode distilasi. Pembentukan HEAI dikonfirmasi dengan uji kromatografi lapis tipis, spektrofotometer inframerah transformasi Fourier, dan ultraviolet-tampak. Suhu efektif untuk konversi asam oleat menjadi HEAI adalah 190 oC dengan kemurnian HEAI mencapai 65%. Akan tetapi, kemurnian HEAI tidak berbanding lurus dengan jumlah kalor yang diserap oleh reaksi pada suhu tertentu.
