Judul: Perencanaan pengembangan perikanan budidaya air tawar di Kabupaten Bogor Provinsi Jawa Barat
Abstrak: Bogor regency as a buffer zone of Jakarta has long been known as one of the central production of freshwater aquaculture in West Java Province. Beside for self-sufficient, Bogor regency also required to meet the needs of freshwater edible fish for the city of Jakarta. Increasing of development in Bogor regency has affect land use change, such as reducing area for freshwater aquaculture. The objectives of the study were: (1) to identify the existing condition of freshwater aquaculture in Bogor regency, (2) to analyze the role of fisheries and its lingkages with other sectors, (3) to analyze potential area for development of freshwater aquaculture, (4) to explore the perception of stakeholders about the development of freshwater aquaculture, and (5) to analyze the external and internal factors for the development of freshwater aquaculture in Bogor regency, including its strategic plan development. The results have shown that aquaculture production reached 36.007,73 tons with 6.782 farmer and productivity of 5,31 tons/farmer in 2010. Fish consumption rate is 20,95 kg/capita/year with population of 4.763.209. Input-output analysis shown that the fisheries sector has high backward with low foreward power of dispersion. From the stakeholders point of view, the most influential aspect is the economical and the utilization of fishing hatchery aspects. Moreover, further analysis shows that even though the freshwater aquaculture in Bogor regency experiencing many threats, however, at the same time it also has its internal strength. Therefore, the appropriate strategic development of aquaculture in Bogor regency, recommended are: retaining potential fisheries area and preventing land use change; utilizing fish species which are tolerant to water quality; increasing the use of technology and new discovery in cheap protein feed manufacturing; and the utilization of stem and improved seeds.

Judul: Peranan Sektor Perikanan dalam Pembangunan Wilayah Kabupaten Bogor, Provinsi Jawa Barat
Abstrak: Kabupaten Bogor merupakan salah satu kabupaten di Provinsi Jawa Barat yang tidak mempunyai laut, namun memiliki potensi perikanan air tawar yang cukup besar. Untuk mengetahui kontribusi sektor perikanan terhadap PDRB digunakan analisis Shift share, sedangkan untuk mengetahui peranan sektor perikanan dalam pembangunan wilayah Kabupaten Bogor digunakan analisis LQ yaitu untuk menentukan apakah sektor perikanan merupakan sektor basis ekonomi atau tidak, baik dari indikator pendapatan wilayah dan penyerapan tenaga kerja, selain itu digunakan anilisis SWOT untuk mengetahui alternatif strategi pengembangan sektor perikanan. Hasil penelitian menunjukkan bahwa sektor perikanan di Kabupaten Bogor bukan merupakan sektor basis dilihat dari indikator pendapatan maupun tenaga kerja hal ini disebabkan nilai LQ sektor perikanan berdasarkan indikator pendapatan dan tenaga kerja kurang dari satu (<1), sehingga untuk memenuhi kebutuhan akan sektor perikanan Kabupaten Bogor harus mengimpor dari iuar daerah. Sedangkan berdasarkan analisis Shift share, kontribusi sektor perikanan dari tahun 1996-2000 tidak banyak mengalami perubahan yaitu dari 0,19;0,16;0,18;0,19;0,18. Berdasarkan analisis SWOT alternatif strategi yang dapat diterapkan dalam upaya pengembangan usaha perikanan di Kabupaten Bogor adalah pemanfaatan potensi dalam peningkatan produksi untuk memenuhi kebutuhan lokal maupun luar daerah dan untuk meningkatkan laju pertumbuhan ekonomi; pengembangan usaha perikanan dengan memanfaatkan fasilitas-fasilitas yang ada; meningkatkan peran masyarakat dalam pengelolaan sumberdaya dengan meningkatkan pengetahuan, keterampilan, dan kesadaran masyarakat untuk melindungi sumberdaya perikanan.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
