Judul: Pengembangan Perikanan Tangkap Untuk Pemberdayaan N '  Di Kepulauan Riau Daiam Perspekti Otonomi Daerah
Abstrak: Penelitian ini bertujuan untuk menentukan jenis teknologi penangkapan ikan untuk pemberdayaan nelayan Kabupaten Kepulauan Riau berdasarkan kriteria aspek biologis, teknis, sosial, ekonomis dan kebijakan melalui pendekatan skoring dan analytical hierarchy process (AHP). Jenis teknologi penangkapan ikan yang potensial dikembangkan adalah pukat cincin, jaring insang hanyut, jaring udang, jaring kembung, bagan tancap, bubu dasar, rawai dasar dan sero tanam. Dari kedelapan jenis tersebut akan dipilih tiga teknologi peikanan tangkap.

Judul: Teknologi penangkapan ikan pilihan untuk pengembangan penangkapan ikan di Pariaman Sumatera Barat
Abstrak: Penelitian ini bertujuan untuk mencari atau menye- leksi jenis teknologi penangkapan ikan yang sesuai untuk dikembangkan di wilayah perairan Pariaman dari beberapa alternatif jenis teknologi yang ada. Metoda yang digunakan dalam penelitian ini adalah metoda survei. Data diperoleh dari nelayan dan instansi- instansi yang berkaitan dengan materi penelitian. Sedang- kan analisa terhadap teknologi penangkapan ikan dilakukan melalui penilaian aspek biologi, sosial, teknis dan eko- nomi dengan cara skoring. Skoring tersebut dilakukan un- tuk penilaian-penilaian pada kriteria yang mempunyai sa- tuan berbeda. Pada penilaian dari semua kriteria secara terpadu, maka dilakukan penstandaran nilai dengan cara fungsi nilai dari analisa keputusan. Potensi lestari sumberdaya perikanan laut di Kecama- tan Pariaman sebesar 11.778,7 ton/tahun. Tingkat peman- faatan pada tahun 1987 sebesar 3.781,3 ton (32,10%) se- hingga potensi lestari yang masih dapat dimanfaatkan se- besar 7.997,4 ton (67,90 %). Hasil produksi perikanan laut Kecamatan Pariaman bagian besar terdiri dari ikan pelagis dan demersal. Selain untuk konsumsi lokal, produksi ikan juga dipasarkan ke luar kota maupun ke luar daerah Sumatera Barat. Dari hasil analisa aspek biologi, unit penangkapan tonda baik untuk dikembangkan, ditinjau dari aspek sosial unit penangkapan bagan motor baik untuk dikembangkan, se- dangkan secara teknis maupun ekonomis unit penangkapan bagan motor juga yang baik untuk dikembangkan. Penilaian terhadap keempat aspek di atas secara kese- luruhan menempatkan unit penangkapan bagan motor pada urutan prioritas pertama yang baik untuk dikembangkan, kemudian diikuti oleh unit tonda, payang, jaring insang dan akhirnya pukat tepi….

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
