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: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
