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 Gelatin Kulit Ikan dan Pemanfaatannya untuk Kapsul Keras
Abstrak: Gelatin merupakan produk yang banyak dimanfaatkan, salah satunya sebagai bahan baku pembuat kapsul keras. Tujuan penelitian ini ialah menentukan karakteristik gelatin dari kulit ikan tuna sirip kuning dan kulit ikan patin serta menentukan karakteristik cangkang kapsul keras. Gelatin dihidrolisis menggunakan asam sitrat 0,25%. Pembuatan kapsul keras terdiri dari kapsul gelatin tuna sirip kuning, kapsul gelatin patin, serta kapsul campuran antara gelatin tuna-patin yang dibandingkan dengan kapsul komersial. Rancangan percobaan dalam penelitian ini ialah Rancangan Acak Lengkap. Karakteristik gelatin kulit ikan tuna sirip kuning dan patin masing-masing yaitu pH 4,85±0,12 dan 5,06±0,03; kekuatan gel 184,33±8,00 g bloom dan 129,83±8,52 g bloom; kadar air 7,03±0,72% dan 5,87±0,37%; kadar abu 0,52±0,04% dan 0,58±0,04%; setting point 23,17±1,04oC dan 18,00±1,32oC; viskositas 31,13±3,02 cP dan 9,97±0,60 cP; warna L 37±0,51 dan 57,92±0,6; serta whiteness 34,91±0,46% dan 51,47±0,52%. Hasil analisis SDS-PAGE menunjukkan adanya ikatan β, α1 dan α2 pada gelatin tuna dan ikatan α1 dan α2 pada gelatin patin. Kapsul patin dan campuran tuna-patin memiliki sifat yang relatif sama.

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.
