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: Analisis Ketimpangan Pembangunan Wilayah di Kabupaten Bogor
Abstrak: The purpose of these study are: (1) understand and identify the linkages between economic sectors in Bogor Regency, (2) understand the inter-area development districts in Bogor, (3) understand and identify the pattern of development activity in the sector, Bogor regency, and (4) recommend policy direction to sectoral development priorities in Bogor to reduce regional development disparities. This research was conducted in Bogor, West Java, with unit area of observation there were 40 subdistricts in Bogor. The result of updating the 2008 IO table analysis is showed that, (1) the sector of non-oil & gas industry (INM), and sector of electricity, gas and water supply (LGA) has a key sector in Bogor regency. 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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
