Actual Land Use and Allocation of Space and Land Status (Case Study Bogor
District of West Section).
Abstrak: Pemekaran wilayah sudah banyak dilakukan dan tampaknya akan terus terjadi, seperti wacana pemekaran Kabupaten Bogor bagian Barat. Pembentukan wilayah otonomi baru memerlukan persiapan yang penting. Antara lain dalam level pemanfaatan sumberdaya fisik wilayah. Tujuan dari penelitian ini adalah : (1) Mengidentifikasi jenis-jenis penggunaan lahan saat ini di Kabupaten Bogor bagian Barat dan, (2) Mengevaluasi keserasian antara penggunaan lahan dengan alokasi ruang dan status lahan di wilayah ini berdasarkan RTRW Kabupaten Bogor Tahun 2005-2025. Analisis yang dilakukan dalam penelitian adalah analisis keselarasan dan analisis tumpang-tindih, kedua analisis tersebut sangat relevan dilakukan dalam rencana pemekaran suatu wilayah. Informasi yang diperoleh merupakan dasar dalam penataan ruang wilayah baru. Hasil analisis penggunaan lahan didapatkan 10 jenis penggunaan lahan yaitu hutan yang merupakan penggunaan lahan terluas, diikuti oleh kebun campuran, tegalan, sawah, pemukiman, semak, perkebunan, tubuh air, pertambangan, danau dan industri. Informasi mengenai status lahan terbagi menjadi 4 status lahan , yaitu : tanah negara dikuasai , hak milik, hak adat dan hak guna usaha. Berdasarkan RTRW Kabupaten Bogor Tahun 2005-2025 alokasi ruang wilayah Kabupaten Bogor bagian barat terdiri atas Kawasan Lindung 16890 Ha (15,0 %) dan Kawasan Budidaya dengan luas 92580 Ha (82,4 %). Analisis tumpangtindih antara penggunaan lahan saat ini, status lahan yang ada dan alokasi ruang di wilayah Kabupaten Bogor bagian Barat telah dilakukan. Hasilnya menjelaskan bahwa terdapat ketidakserasian antara Kawasan Hutan Konservasi terdapat penggunaan lahan lain selain hutan yaitu : kebun campuran, permukiman, perkebunan, pertambangan, sawah dan tegalan dengan status lahan Hak Guna Usaha dan Hak Milik. Dalam Kawasan Perkebunan status Hak Guna Usaha terdapat aktivitas masyarakat bercocok tanam. Kebun campuran hasil dari aktivitas masyarakat yang dijumpai pada seluruh alokasi ruang dan status lahan yang berbeda dengan luas yang beragam.

Judul: Analisis Perubahan Penggunaan Lahan, Pola Ruang dan Tingkat Perkembangan Wilayah di Kota Bogor
Abstrak: Bogor City is located 60 kms from the Indonesian Capital Jakarta and 120 kms from Bandung the capital of West Java Province. Strategic agricultural land and inexpensive land price have encouraged stakeholders to invest in agricultural sector and also non agricultural sector. Land use conversion is inevitable, although the goverment has set up the regulation to control land usage (Act No 26 year 2007). This research are conducted: (1) To analyze existing land use of Bogor City (land use in 2014). (2) To analyze the land use change in period of 2005-2012. (3) To analyze the consistency of existing land use compare to land allocation in the RTRW of Bogor City. (4) To identify regional development hierarchy level in Bogor City. (5) To determine factors that influencing land use change. This research was started with land usage map designing which retrieved from digitized result on administrative map 1: 5000 scales to ikonos image of Bogor City in years of 2005 and 2012. Consistency and inconsistency is obtained by overlaying land use map in 2012 and land allocation map of Bogor City years 2011-2031 (RTRW map). PODES is used to determine the regional hierarchy level by multiple regression method. Existing land use classified into 9 land use, in sequence from the largest one are: mixed garden, non-wellarrang ed settlement, paddy field, well arranged settlement, trade area, water body, dryland farm, open field and goverment office area. Dryland farm land use changes into 2 land use, open field land use change into 6 land use and paddy field land use change into 6 land use. The consistent existing land use compare to RTRW is 40.95% while inconsistence existing land use is 59.05%. During period of 2006 to 2012, most of regional development hierarchy in Bogor City are the relative constant hierarchy (42 villages/61.8%). 12 villages (17.6%) are increase in the hierarchy whilst 14 villages (20.6%) are decrease in the hierarchy. Factors that influencing land use change of Bogor City in period of 2005-2012 are: area of agricultural land in the years of 2005, social facilities growth, and economy facilities growth

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
