Judul: Perencanaan Pembangunan Wilayah Berbasis Perikanan Tangkap secara Terpadu di Kecamaan Tanjung Mutiara Kabupaten Agam Propinsi Sumatera Barat
Abstrak: Pembangunan perikanan tangkap di Kecamatan Tanjung Mutiara membutuhkan sebuah perencanaan secara terpadu agar terjamin keberlanjutan dan kebersinambungan dengan sektor lain di wilayah pesisir. Perencanaan pembangunan perikanan tangkap dimulai dari menentukan peranan, komponen-komponen dan berakhir dengan menghasilkan kebijakan pembangunan perikanan tangkap.

Judul: Analisis pembangunan perikanan tangkap di kabupaten paisir selatan Sumatera Barat
Abstrak: Tujuan penelitian ini adalah menganalisis perkernbangan tenaga kerja sub sektor perikanan di kecamatan pesisir Kabupaten Pesisir Selatan, menganalisis status keberlanjutan sumber daya ikan yang dirnanfaatkan oleh pukat pantai, payang, bagan, pancing tonda dan mini trawl. Selanjutnya berdasarkan hail kedua analisis tersebut, dirumuskan alternatif kebij akan y ang hams dilakukan agar pembangunan perhnan tangkap Kabupaten Pesisir Selatan bisa berkembang secara optimal dan tetap mempertimbangkan aspek kelestarian. Penelitian ini menggunakan dua me& evaluasi yaitu metode Location Quotient untuk menganalisis ekonomi wilayah dan metoda Rapfish untuk menganalisis tingkat keberlanjutan. Metoda Rapfish mengevduasi pembangunan berkelanjutan dengan mempertimbangkan krbagai dimensi seperti dimensi ekologi, ekonomi, sosial, teknologi, dan etika. Beberapa atribut dalam Rapfish juga dapat diverifikasi dengan hasil analisis LQ. Berdasarkan Analisis LQ, didapat beberapa kecamatan yang mempunyai sektor basis pada penkanan tangkap yaitu: Kecamatan Koto XI Tarusan, Sutera, Lengayang, Linggo Sari, Baganti dan Ranah Pesisir. Selanjutnya perbandingan antara jurnlah tenaga kerja yang beke j a pada sub sektor perikanan dengan kontribusi pertumbuhan sub sektor perikanan dalam pembentukan PDRB ternyata tidak seimbang. Dimana pertumbuhan tenaga kerj a jauh lebih tinggi dibandingkan kontribusi sub sektor perikanan terhadap pertumbuhan PDRB, sehingga berimplikasi pa& penman produktivitas nelayan dari tahun-ketahun. Ini menandakm j umlah tenaga kerja yang bekerja pada sub sektor perikanan melebihi kapasitas surnber daya ikan yang tersedia. Ini merupakan faktor penting yang mengakibstkan terjadinya Malthusian over fishing.

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
