Judul: Fisheries Industry Development Model of the Kepulauan Seribu Administrative District
Abstrak: kabupaten Administrasi Kepulauan Seribu di Provinsi DKI Jakarta merupakan salah satu kabupaten yang memiliki karakteristik wilayah pesisir dan perairan. Ironisnya, sebagian wilayah perairan Kepulauan Seribu ditetapkan sebagai kawasan konservasi yang dikenal dengan Taman Nasional Laut Kepulauan Seribu. Kondisi in imenghendaki adanya prioritas pembangunan perikanan (TPP) serta strategi mengelola interaksi yang terjadi antarfaktor dalam pembangunan daerah. Beberapa faktor pembangunan perikanan meliputi: kewenangan bagi pemerintah (KBP), Kewenangan bagi Pemerintah Daerah Otonom (KBO), lingkungan usaha perikanan (LUP), kegiatan perikanan tangkap (TKP), kegiatan perikanan budidaya (BDY), dan kegiatan pengolahan hasil perikanan (PROS).

Judul: Kebijakan Pengembangan Ekonomi Perikanan Tangkap Berkelanjutan di Provinsi DKI Jakarta
Abstrak: Capture fisheries subsector in DKI Jakarta Province has been facing serious problems on various dimensions. Those problems threat its sustainability in the future. Fisheries sustainability is determined by several interacting dimensions such ecology, economic, social. technology and institution. The purpose of this research is to 1) estimate optimum alocation of capture fisheries in DKI Jakarta Province, 2) determine the degradation and depreciation level of capture fisheries in DKI Jakarta, 3) determine the sustainability status of capture fisheries in DKI Jakarta according five sustainability dimensions (ecology, economy, social, technology, and institution), 4) determine dynamic optimation management of capture fisheries in DKI Jakarta Province, and 5) formulate policy direction of economic development of sustainable capture fisheries in DKI Jakarta Province. The fisheries resources on this research seperated as pelagic and demersal. The research used bioeconomic analysis, degradation and depreciation analysis, sustainable analysis with Rapfish techniques and dynamic analysis. Result of the bioeconomic analysis showed that the harvest and effort of pelagic and demersal resources were above than optimal level therefore those resources have been over exploited. Degradation and depreciation analysis showed that pelagis resouce have been degraded dan depreciated meanwhile demersal resource have been not degraded dan depreciated. Sustainable analysis with Rapfish techniques using multi dimension scalling (MDS) and modification of AHP showed that the sustainability index of pelagic was 39,63. Based on categorized, it means was in less sustainable with economic dimension as the most priority dimension that influently to sustainability of pelagis resources. Mean while, the sustainability index of demersal resources was 37,15. It means the resource was less sustainable with ecology dimension as the most priority dimension. The dynamic model of this research was composed of three sub models, such as ecology, economic and social. Those sub models were used to predict of sustainability indicators on each dimension. The indicator of ecology, economic and social model were natural stock of resources, profit and profit to UMR. Result of dynamic analysis showed that limiting number of fishing effort can kept the natural stock of fish on sustainable stock. Based on result of all analysis, one of the best policy to improve sustainability of capture fisheries in DKI Jakarta is synergetic policy which consider ecology, economic, and social indicators.

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.
