Judul: Peranan dan Strategi Pengembangan Sektor Kelautan dan Perikanan di Era Otonomi Daerah Kabupaten Ciamis, Provinsi Jawa Barat
Abstrak: Pembangunan Daerah pada intinya adalah pemberdayaan wilayah dan masyarakat, pertumbuhan prakarsa serta kreativitas. Salah satu indikator tingkat kemajuan dan kesejahteraan masyarakat di suatu daerah adalah Pendapatan Domestik Regional Bruto (PDRB) per kapita yang menggambarkan besarnya pendapatan rata-rata yang mungkin dicapai masyarakat. Suatu sektor digolongkan sebagai basis ekonomi di suatu daerah jika sektor tersebut telah mampu berswasembada dalam memenuhi konsumsi daerah dan menghasilkan surplus untuk ekspor ke luar daerah. Keterkaitan dalam pelaksanaan otonomi daerah yaitu Undang-Undang Nomor 22 Tahun 1999 tentang Otonomi Daerah dan Undang-Undang Nomor 25 Tahun 1999 tentang Perimbangan Keuangan Pusat dan Daerah, mendasari perlunya penelitian terhadap sektor kelautan dan perikanan sebelum dan setelah undang-undang tersebut diberlakukan. Penelitian ini bertujuan untuk mengetahui peranan dan kontribusi sektor kelautan dan perikanan di era otonomi daerah, sehingga dapat dirumuskan strategi pengembangannya

Judul: Peranan Subsektor Perikanan Tangkap terhadap Pembangunan Wilayah Kabupaten Sukabumi, Provinsi Jawa Barat
Abstrak: Dalam rangka meningkatkan peranan dan kontribusi suatu sektor terhadap PDRB mau pun PDRB per kapita terus dilakukan, diantaranya melalui optimalisasi penggunaan sumberdaya alam yang dimiliki. Penggunaan sumberdaya alam harus diprioritaskan pada sektor antara lain komoditas yang belum dimanfaatkan secara optimal. Penelitian ini bertujuan untuk melihat sejauh mana kontribusi sektor perikanan dan kelautan khususnya subsektor perikanan tangkap terhadap pembangunan wilayah Kabupaten Sukabumi, Provinsi Jawa Barat. Penelitian ini menggunakan metode studi kasus, data dianalisis menggunakan analisis Location Quotient, Multiplier Effect dan penentuan sektor unggulan. Selama periode 2000-2006 peranan sektor perikanan dan kelautan Kabupaten Sukabumi berdasarkan hasil analisis Location Quotient dengan indikator pendapatan wilayah menunjukkan bahwa sektor perikanan dan kelautan Kabupaten Sukabumi merupakan sektor basis. Dengan demikian, sektor perikanan dan kelautan Kabupaten Sukabumi mampu menciptakan kesempatan kerja untuk memenuhi kebutuhan pasar di dalam wilayah maupun permintaan pasar di luar wilayah atau ekspor. Selama periode tahun 2000-2006 subsektor perikanan tangkap berdasarkan indikator pendapatan wilayah, memberikan dampak positif dan cenderung meningkat terhadap pembangunan wilayah Kabupaten Sukabumi.

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
