Judul: Penilaian Data yang Diperlukan untuk Menyusun Strategi Pengelolaan Rajungan di Teluk Jakarta
Abstrak: Teluk Jakarta merupakan kawasan penangkapan rajungan yang harus dikelola oleh Pemerintah Provinsi DKI Jakarta. Dalam mengelola perikanan rajungan. Pemerintah DKI Jakarta memerlukan berbagai data dan informasi sebelum akhirnya dapat merancang strategi pengelolaan. Informasi yang diperlukan berupa: (1) habitat rajungan; (2) sebaran rajungan yang cocok untuk ditangkap; (3) nilai potensi berkelanjutan Teluk Jakarta; dan (4) kapasitas penangkapan rajungan. Tantangan yang dihadapi oleh Pemerintah DKI Jakarta saat ini adalah apakah data/informasi yang dibutuhkan tersebut ada tersedia atau justru tidak ada, bagaimana dengan akses untuk mendapatkan data tersebut apakah mudah atau sulit, dan apakah data tersebut sudah cukup atau belum cukup. Dampak negatif yang akan terjadi apabila rencana strategi pengelolaan tidak dibuat dengan baik antara lain dari aspek efektivitas akan berakibat pada sulitnya pelaksanaan pengelolaan dan peningkatan kinerja dalam kegiatan pengelolaan, dari aspek sasaran pengelolaan yaitu ekosistem dan nelayan Teluk Jakarta akan berakibat pada tidak optimalnya pengelolaan ekosistem rajungan. Penelitian ini dilakukan untuk menilai kualitas dari data dan informasi yang dibutuhkan oleh Pemerintah Daerah DKI Jakarta serta bagaimana hasil informasi yang dapat dibuat, dan menilai secara kualitatif komprehensif keempat informasi yang ada agar dapat dijadikan landasan dalam menyusun rencana strategi pengelolaan rajungan di Teluk Jakarta dengan baik. Data dan informasi yang diperlukan harus baik dan cukup agar dapat digunakan untuk merancang suatu perencanaan dengan menghasilkan rancangan strategi pengelolaan yang efisien dan efektif. Sehingga perlunya indikator yang dapat dijadikan tolak ukur dari kualitas informasi antara lain ketersediaan data, kemudahan dalam memperoleh data, dan kecukupan data Indikator tersebut dapat dijadikan tolak ukur pada setiap data dan informasi yang akan membantu Pemerintah DKI Jakarta dalam menyusun rancangan strategi pengelolaan rajungan di Teluk Jakarta. Data yang dikumpulkan merupakan data yang tersedia atau yang dapat dikumpulkan oleh Pemerintah Daerah DKI Jakarta melalui penelusuran data/informasi statistik di berbagai instansi pemerintah/non pemerintah, survei lapangan, wawancara dengan nelayan dan berbagai sumber lainnya. Analisis skoring dilakukan untuk setiap jenis data, yang terdiri dari: (A) keberadaan data; (M) aksesibilitas data; dan (C) kecukupan data. Penyusunan informasi dilakukan untuk membuktikan apakah data yang tersedia saat ini dapat disusun menjadi informasi atau tidak. Penilaian keempat informasi dilakukan secara kualitatif komprehensif dengan cara menganalisis setiap kategori informasi yang telah ada, apakah setiap informasi tersebut sudah cukup ataukah justru membutuhkan pengumpulan data lebih lanjut dikarenakan kurangnya data dan informasi pada setiap kategori. Hasil skoring menunjukkan bahwa data untuk: pembuatan peta habitat rajungan, pembuatan peta lokasi dan ukuran rajungan yang ditangkap, pendugaan potensi hasil lestari, dan pendugaan kapasitas penangkapan adalah 570, 500, 620,

Judul: Sustainable management of capture fishery in Jakarta Waters, DKI Jakarta Province
Abstrak: Jakarta Waters is categorized as fully exploited water areas which its coastal areas accommodate multifunction services. Therefore, it needs precautionary approach to manage fisheries activity and its resource in the location. This is important to sustain the potential resource, provide prosperity to fishermen as well as coastal communities. The general objectives of this study are to arrange the sustainable fishery management in Jakarta Waters, while specific objectives of this study are to evaluate capture fishery management status; to determine optimum allocation of potential fishing gears and fisheries development areas based on potential fishing gears; to analyze the various components affecting to capture fishery activity based on suitable area and to analyze internal and external conditions in order to arrange the strategies for sustainable fishery management in Jakarta Waters. The methods used in this study were system approach, SWOT analysis, Linear Goal Programming (LGP) analysis, analysis of Location Quotients (LQ), Geographic Information System (GIS) analysis, and Analytical Hierarchy Process (AHP) method. The results revealed that the management of capture fishery in Jakarta Waters was categorized as "kurang baik" with the total scores of 2.529 and 2.747 for internal and external factors analysis, matrix IE pointed out that the position of fishery management at growth level which need strategy to do coordination horizontally with the other stakeholders. By using GIS analysis, it was identified that 52,89% of Jakarta Waters can be used for capture fishery, less than 25% can be used for fish farming (cage culture) and less than 15% can be used for seeweed culture. Meanwhile the potential fishing gears to be developed were pelagic danish seine, drift gillnet, boat lift net, set bottom long line, portable trap and muro ami which have the optimum allocation for each fishing gear; 7 units, 98 units, 23 units, 18 units, 8547 units, and 798 units. The potential fishing gears for pelagic danish seine could be developed in Penjaringan and North Seribu Island Districts; drift gillnet could be developed in Cilincing District; boat lift net could be developed in Penjaringan District; set bottom long line could be developed in Penjaringan District; portable trap could be developed in Cilincing and South Seribu Island Districts while muro ami could be developed in Penjaringan and South Seribu Island Districts. The study identified that there are several important strategies to support sustainable capture fishery management, from the first priority to the last are small-scale fishery standardization, integrated management to conserve the ecosystem function, quality product improvement, fishing days opreration management by implementing closed – open seasons, increasing independent fishermen capability, human resources empowerment, extention for fishermen and increasing capture fishery activities supervision. As the first priority, the standardization of small-scale fishery should be stable against changes in the dimension of biology and quite stable against changes in the ecological, economic, social and technological dimension.

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.
