This sector has the power distribution and a strong degree of sensitivity; (2) the economic activity is concentrated in the center area of Bogor regency, but physical activity has started to spread out from the middle region of Bogor district, namely the western and eastern parts of Bogor Regency; (3) in economic activity, the pattern of regional economic development was still in the near town area of Bogor (center region). But physically (landuse), physical development pattern of the area has moved out of the area west of Bogor regency. (4) variables that have relationships with the regional development disparities in Bogor Regency are the ratio of human resources with the hierarchy of the region in 2006, the ratio of human resource with hierarchy of the region in 2008, and hierarchy of the region in 2006 with hierarchy of the region in 2008.

Judul: Analisis keterkaitan struktur potensi permasalahan pembangunan dan upaya pengembangan wilayah kabupaten Bogor bagian barat
Abstrak: Struktur potensi dan permasalahan pembangunan yang dihadapi oleh tiap-tiap wilayah berbeda-beda. Perbedaan ini dapat berakibat pada ketimpangan pembangunan, baik ketimpangan antar sektor maupun antar wilayah. Untuk itu diperlukan perencanaan pembangunan agar tercipta pemerataan pembangunan dan hasil-hasilnya di setiap lapisan masyarakat pada masing-masing wilayah. Beberapa indikator utama yang berkaitan dengan proses pembangunan antara lain adalah: aktifitas perekonomian yang secara sederhana dapat diukur dengan Produk Domestik Regional Bruto (PDRB) dan tingkat inflasi, pola penggunaan lahan, produktivitas tahan, serta ketersediaan sarana dan prasarana. Dari kelima indikator tersebut dapat dianalisis struktur potensi dan permasalahan dalam proses pembangunan wilayah, dalam hal ini pembangunan daerah. Tujuan dari penelitian ini adalah (1) menganalisis struktur potensi dan permasalahan pengembangan wilayah Kabupaten Bogor bagian Barat berdasarkan lima indikator, yakni: PDRB. tingkat inflasi, pola penggunaan lahan, produktivitas tahan, serta ketersediaan sarana dan prasarana, (2) menentukan hirarki Wilayah Bogor bagian Barat berdasarkan ketersediaan sarana dan prasarana sebagai fasilitas yang dimiliki setiap wilayah, (3) mengelompokkan wilayah-wilayah kecamatan di Kabupaten Bogor bagian Barat berdasarkan potensi dan struktur permasalahan yang terkait dengan kelima indikator tersebut, (4) menentukan rekomendasi pengembangan Wilayah Kabupaten Bogor bagian Barat berdasarkan stuktur potensi dan permasalahan dari kelima indikator tersebut.

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.
