Judul: Analisis Penyelenggaraan Penyuluhan Perikanan di Kabupaten Halmahera Utara
Abstrak: Pembangunan dapat memiliki makna sebagai upaya membangun masyarakat sekaligus mempertahankan kelestarian sumberdaya alam, termasuk sumberdaya kelautan dan perikanan. Oleh karena itu pembangunan masyarakat dan sumberdaya kelautan dan perikanan, tidak dapat dipisahkan. Hal ini didasarkan atas sebuah anggapan yang menyebutkan bahwa salah satu penyebab kemiskinan adalah sumberdaya alam yang dipandang terbatas atau tidak tersedianya sumberdaya alam konvensional yang biasanya digunakan oleh masyarakat nelayan, Dahuri (2000). Hal tersebut bisa terjadi karena dua hal yaitu pertama kondisi geografi dan ekologi yang memang tidak mendukung dan kedua teknologi yang dimanfaatkan oleh masyarakat masih sangat sederhana. Untuk itu dalam melaksanakan pembangunan seharusnya dipandang sebagai suatu kesatuan agar tidak terjadi tumpang tindih yang akan mengakibatkan kerusakan di bagian lainnya. Berkenaan dengan itu, Dahuri (2003) menganjurkan agar perlunya penerapan konsep pembangunan berkelanjutan dalam pengelolaan perikanan, yang secara teknis dapat didefenisikan bahwa pembangunan perikanan berkelanjutan adalah suatu upaya pemanfaatan sumberdaya alam kelautan dan jasa-jasa lingkungan yang terdapat didalamnya untuk kesejahteraan manusia dengan tetap memperhatikan aspek ekologi, sosial dan ekonomi. Dalam hal ini pembangunan perikanan harus menghasilkan sesuatu yang bermanfaat bagi kesejahteraan masyarakat tanpa mengabaikan prinsip-prinsip kelestarian sumberdaya alam dan lingkungan hidup agar dapat memenuhi kebutuhan generasi kini dan akan datang. Menuju tercapainya tujuan pembangunan kelautan dan perikanan, pengembangan sumberdaya manusia merupakan faktor kunci yang harus diperhatikan. Salah satu upaya dalam mewujudkan hal tersebut adalah melalui pengembangan program kegiatan penyuluhan perikanan. Kabupaten Halmahera Utara yang cukup besar dan memiliki daya tarik untuk pengembangan perikanan tangkap. Namun kondisi ini pada kenyataannya belum meningkatkan pendapatan masyarakat nelayan, oleh karena berbagai kendala terutama sumberdaya nelayan masih rendah....dst

Abstrak: The objectives this research were : (1) to assess the impact of fishing unit assistance to increasing fisheries income level, in North Halmahera Regency, (2) to assess influence mayor factors of fisheries income level (3) to selection of alternative policy strategy for sustainable increasing fisheries income level. Result of this research show that, most of the level of fishing technology used is relatively simple, except pajeko fishing technology has relatively advanced technology. The fishing unit’s empowerment program significantly positive impact on improving the income of fishermen. Based on feasible and investment criteria analysis indicate pajeko fishing unit of gillnet, bottom long line and mini purse seine more feasible to be developed in North Halmahera regency. Result of matrix internal factors analysis summary (IFAS) indicated that total factor internal value in IFAS between 3,1 ³ 2,5, its mean internal condition had strength to overcome weakness state. Whereas result external factors analysis summary (EFAS) show that the total EFAS value between 2,6 ³ 2,5, its mean system capable to response external state. Base on SWOT (strenght–weakness, opportunity-threat) analysis obtain six development strategies of increasing fisheries income: (1) Scale business fisheries development; (2) Improved fishing infrastructure; (3) Development of market aces (4) Training programs for fisheries capacity development; (5) The Law enforcements; (6) Partnership development.

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
