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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
