Judul: Pengaruh jenis alat penggiling terhadap karakteristik kitin dari kulit rajungan
Abstrak: Kitin adalah senyawa polimer alami, yang memiliki rantai molekul panjang dan tidak bercabang serta bobot molekulnya tinggi, yang dihasilkan dari limbah hasil laut khususnya golongan udang, kepiting, ketam, dan kerang. Selain sifat fisika dan kimia, penelitian mengenai proses penggiliigan perlu dilakukan untuk melihat ukuran serpihan kitin yang dihasilkan. Dengan dilakukannya proses penggilingan, dapat dilihat faktor keseragaman ukuran serpihan kitin yang dihasilkan dari penggunaan dua alat penggiling berbeda, tanpa mengubah sifat kimia dari bahan.

Judul: Karakteristik Sifat Fisik Tepung Ikan Serta Tepung Daging dan Tulang
Abstrak: Bahan pakan sumber protein hewani sangat penting bagi ternak, karena kandungan protein dan asam aminonya tinggi, tetapi harganya lebih mahal dibandingkan sumber energi dan sumber protein nabati, maka diperlukan perhatian khusus terhadap pengawasan mutu dan penyimpanan agar kualitas bahan pakan sumber protein hewani tidak menurun. Sifat fisik merupakan salah satu pengujian secara cepat untuk menentukan bahan baku pakan diterima atau tidak dalam proses quality control, maka penelitian tentang sifat fisik bahan baku pakan perlu dilakukan. Penelitian ini dilaksanakan selama tiga bulan mulai dari bulan Juni sampai dengan bulan Agustus 2005 di Bagian Ilmu dan Teknologi Pakan, Departemen Ilmu Nutrisi dan Teknologi Pakan, Fakultas Peternakan, Institut Pertanian Bogor. Metode yang digunakan dalam penelitian ini adalah metode Rancangan Acak Lengkap (RAL) untuk tepung daging dan tulang dengan 2 perlakuan dan 4 ulangan. dan tepung ikan menggunakan Rancangan Acak Lengkap (RAL) Faktorial 2×2×4, dua untuk asal pemasok dari industri besar dan kecil, 2 asal tepung ikan dari lokal dan impor dengan 4 kali ulangan. Peubah yang diamati adalah kadar air (%), berat jenis (g/ml), kerapatan tumpukan (g/ml), kerapatan pemadatan tumpukan (g/ml), sudut tumpukan (0), dan daya ambang (m/det).

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.
