Judul: Penggunaan/Penutupan Lahan dan Kaitannya dengan Pertumbuhan Ekonomi Wilayah (Studi Kasus Kota Bogor)
Abstrak: Rapid population growth will implied the need for space to accommodate their activity. And one of it manifested in the shape of built up area. On this land then this population do their activity, individually or in a group. The aims of this study were namely, to analyzes changes in land use/land cover of Bogor Municipality between 2005 and 2007, to analyzes the influence of economic factor to the land use/land cover compositions, and to analyzes the consistency between land use of the Bogor Municipality in 2007 and Regional Spatial Plan (RTRW). In 2005, Bogor Municipality land use/land cover was dominated by settlement with 31,1% (3.563,01 Ha), followed by paddy with 23,2 % (2.656,07 Ha) and urban forest with 13,9% (1.592,75 Ha). There were no change in the land use/land cover domination in 2007. Settlement still dominating Bogor Municipality land use/land cover with a little increase, which is 31,3% (3583,98 Ha). Paddy with the same percentage, which is 23,2% (2658,88 Ha) on second place and urban forest with 13.9% (1592,79 Ha) in third place. Between 2005 and 2007, there were 109,14 Ha land use/land cover change that occurs in Bogor Municipality. The transformation from non used space became a residential is the most dominating transformation, which reach 45 Ha. Followed by the transformation from field became a residential with 21,75 Ha and the transformation from non used space became fields is on the third place with 12,67 Ha. The growth of the population equal to the demand for housing. This is the reason for the developer to build new residential. The Bogor outer ring road project is also suspected as the trigger to the growth of residential area. With this infrastructure built, these new residential will have the best accessibility to or from Jakarta, which is the centre of economic activity in Indonesia. Bogor Municipality consist of two hierarchy, first hierarchy and third hierarchy. The third hierarchy consist of 57 villages. While another eleven 11 were classified as the first hierarchy. Essentially, the first hierarchy is the centre v of general activity and economic activity, which is why the first hierarchy is dominated by built up area, while the third hierarchy is commonly dominated by the non built area. There are two kinds of the inappropriateness between Regional Spatial Plan and 2007 land use. The first one is the Regional Spatial Plan which was built less than the allocated plan, which is dominated by the allocation for health facilities, with 1,8 Ha over 18,3Ha which was allocated. The second is the Regional Spatial Plan which was built more the allocated plan, which is dominated by the allocation for agriculture with 128,4 Ha allocated, but built up to 408,1 Ha. By identifying the inconsistencies of actual land use to Regional Spatial Plan (RTRW), spatial plan deviations in Bogor Municipality can be identified.

Judul: Perubahan Penggunaan/Penutupan Lahan dan Keterkaitannya dengan Luas Ruang Terbuka Hijau ( Studi Kasus Kota Bogor )
Abstrak: The presence of a city has a goal to meet the needs of the population in order to survive and continue living and improve quality of life. However, with the development of a city, there are some fairly complicated urban problems to overcome. Rapid increase in population accompanied by an increase in income per capita has resulted in the need for land to meet the needs of food, clothing, and shelter. Urban developments lead to negative consequences for the environment. Urban environment tends to develop economically and decline ecologically where the city tends to lead to physical development such as infrastructure development. This research was conducted to analyze the change of land use/land cover of Bogor City period 2000-2011, analyzed the level consistent/inconsistent RTH development based on RTRW Bogor City allotment, and analyzed the level of development of Bogor City based on the RTH condition. Land use/land cover in Bogor City in 2000 and 2011 divided into land use/land cover of land classified as RTH and Non-RTH. Land use/land cover which is classified as RTH such as paddy, upland fields, botanical garden, sport fields, public cemeteries, trees, and bushes. While land use/land cover which is classified as non RTH such as bare soil, pools, situ, rivers, settlement, build non settlement (industry, state palace, health area, educations area, station and terminal, commerce area, offices roads, railway stations, and road). Distribution of land use/land cover in the City of Bogor both in 2000 and 2011, dominated by settlements, paddy, and trees. The size of settlements hectares increased from 4.469,9 Ha to 5.289,8 Ha, the large of paddy decreased from 2.904 Ha to 2.452 Ha, and the area of trees decreased from 2.341,2 Ha to 2.108,1 Ha. Settlements experiencing the largest increase due to 360,3 Ha consequence paddy conversion. Appropriateness criteria based RTRW divided into consistent, undeveloped consistent, and inconsistent. The large of land use/land cover which is consistent with the designation is 6.352,2 Ha, undeveloped consistent is in the amount of 5.300 Ha, while the inconsistent is in the amount of 41,6 Ha. The 5 greatest inconsistency occurred in the area should be designated as an agricultural area, but has been 11,3 Ha settlement. Bogor City has 7 villages which belong to the hierarchy I, 22 villages belonging to the hierarchy II, and 39 villages belonging to the hierarchy III. Based on the calculations of data, the large percentage of Bogor City green open space is 46,6% where the area with the hierarchy I has the RTH by 3,4%, 11.4% hierarchy II, and 31,8% hierarchy III. While connected to the level of inconsistency, the region of hierarchy I, there are inconsistencies in large of land use/land cover of 0,2%, 0,3% hierarchy II, and hierarchy III by 0,4%.

Judul: Aplikasi Nano Kitosan Sebagai Pengawet Alami Fillet Nila Merah (Oreochromis Sp.) Selama Penyimpanan Suhu Chilling
Abstrak: Nano kitosan diketahui berpotensi dalam memperpanjang masa simpan produk perikanan karena sifatnya yang tidak beracun, biodegradable, dan memiliki aktivitas antibakteri. Penelitian ini bertujuan menentukan karakteristik nano kitosan dan membandingkan penggunaan nano kitosan dengan formalin dalam mengawetkan fillet ikan nila merah pada penyimpanan suhu chilling. Nano kitosan dibuat dengan metode gelasi ionik dan dikarakterisasi melalui analisis Particle Size Analyzer, mikroskop elektronik payaran, dan Fourier Transform Infrared. Fillet direndam dalam larutan formalin (F), akuades (T), dan nano kitosan (L) selama 5 menit dan nano kitosan 10 menit (S). Fillet disimpan pada suhu 4±1 oC dan dianalisis total mikroba aerob, Total Volatile Base, dan pH pada hari ke-0, 2, 4, 6, 8, 10, dan 12. Karakteristik nano kitosan yang dihasilkan berukuran 512,58 nm dengan morfologi berbentuk bulat dan derajat deasetilasi sebesar 79,49%. Perendaman dengan nano kitosan selama 5 menit merupakan perlakuan terbaik untuk pengawetan fillet. Nilai total mikroba aerob, TVB, dan pH fillet S, L, dan F belum melewati batas aman konsumsi (<5 log cfu/g, <20 mg N/100 g, dan <7) hingga penyimpanan hari ke-12 dan tidak berbeda nyata satu sama lain (p>0,05), sehingga nano kitosan dapat dijadikan pengawet alami fillet nila merah dan dapat menggantikan formalin bila dilihat dari parameter total mikroba aerob, TVB, dan pH.
