Judul: Systems development of fisheries extension on decentralize circumstance in Indonesia
Abstrak: Secara terminologi, desentralisasi diartikan sebagai penyerahan wewenang oleh Pemerintah kepada daerah otonom untuk mengatur dan mengurus urusan pemerintahan dalam sistem Negara Kesatuan Republik Indonesia. Mengacu pada pengertian tersebut tersirat harapan bahwa dalam era desentralisasi masingmasing daerah dapat memanfaatkan sumberdaya produktif secara berkelanjutan. Sebagai negara yang memiliki potensi besar di bidang perikanan dan kelautan, tidak salah jika banyak daerah yang sangat bergantung pada sektor tersebut. Permasalahannya adalah kualitas sumberdaya manusia (SDM) sebagai motor penggerak utama masih rendah kualitasnya. Salah satu cara yang dinilai efektif untuk meningkatkan kualitas SDM adalah penyuluhan. Berdasarkan pemikiran bahwa pendelegasian wewenang penyuluhan dari pemerintah pusat ke daerah dapat mempercepat akselerasi peningkatan kualitas SDM, maka penyuluhan perikanan termasuk urusan yang didesentralisasikan. Meskipun penyerahan kewenangan penyuluhan perikanan kepada pemerintah daerah (desentralisasi) di satu sisi memberikan manfaat langsung terhadap daerah namun disisi lain membawa persoalan terkait dengan institusionalisasi.

Judul: Pengembangan perikanan berbasis karakteristik spesifik dari potensi daerah
Abstrak: Pengembangan kegiatan perikanan hendaknya dilakukan berdasarkan karakteristik potensi yang dimiliki suatu wilayah. Perairan Selatan Jawa mewakili kondisi karakteristik sumberdaya perikanan yang memerlukan pengelolaan secara spesifik. Potensi sumberdaya ikan yang dimiliki sangat besar, namun kegiatan perikanan baru berkembang di beberapa tempat saja yaitu di Palabuhanratu, Cilacap dan Prigi. Penelitian ini bertujuan: 1) menentukan implikasi karakteristik aspek geo-topografi, biologi, teknologi, sosial, ekonomi dan politik terhadap kinerja perikanan, 2) membangun model pengembangan perikanan sesuai karakteristik wilayah, dan 3) merumuskan kebijakan strategis pengembangan perikanan berbasis kewilayahan. Metode pendekatan sistem digunakan untuk menganalisis permasalahan dan membangun model. Rekayasa sistem disusun dalam suatu model, dengan tiga submodel yaitu 1) usaha perikanan (submodel USAHA), 2) kebutuhan pelabuhan perikanan: fungsionalitas dan aksesibilitas (submodel PELABUHAN) serta 3) kebijakan dan kelembagaan (submodel LEMBAGA). Model diawali dengan penentuan sumberdaya ikan unggulan. Perumusan kebijakan strategis menggunakan analisis SWOT dan balanced scorecard. Strategi implementasi model menggunakan teknik interpretative structural modelling (ISM).

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
