Judul: Studi Potensi dan Kelayakan Finansial Agoindustri Perikanan Laut di Indonesia
Abstrak: Indonesia merupakan negara yang cukup potensial dalam bidang agroindustri perikanan laut,bila dihitung dengan Zone Ekonomi Eksklusif (ZEE) wilayah laut Indonesia mencapai 5,8 juta km2. Hal ini berarti dua pertiga wilayah Republik Indonesia berupa Lautan, dengan demikian Indonesia memiliki daerah lautan yang cukup luas dan potensial.Kriteria potensi yang dipelajari dalam penelitian ini adalah potensi bahan baku perikanan laut, potensi usaha agroindustri perikanan laut, potensi pangsa pasar perikanan laut, potensi transportasi dan potensi tenaga kerja di Indonesia.

Judul: Analisis saluran pemasaran produk perikanan laut di DKI Jakarta
Abstrak: Potensi perikanan laut Indonesia yang terdiri atas potensi perikanan pelagis dan perikanan demersal. Potensi tersebut tersebar pada hampir semua bagian perairan laut Indonesia yang meliputi perairan laut teritorial, perairan laut nusantara dan perairan laut Zona Ekonomi Eksklusif (ZEE). Luas perairan laut Indonesia diperkirakan sebesar 5,8 juta km² dengan garis pantai terpanjang di dunia sebesar 81.000 km dan gugusan pulau-pulau sebanyak 17.508 yang memiliki kekayaan akan potensi perikanan. Saat ini Indonesia menempati urutan keenam negara produsen ikan terbesar di dunia, setelah Cina, Peru, India, Jepang dan Amerika Serikat. Perhatian terhadap perikanan semakin besar, hal ini antara lain ditunjukkan oleh penetapan tahun 2004-2005 sebagai tahap persiapan memantapkan dasar gerakan perikanan nasional. Beberapa program yang akan dipilih untuk dikembangkan, di antaranya adalah industri tambak udang di Jawa Barat, Sulawesi Selatan, dan Sumatera Selatan. Kemudian, pengembangan usaha perikanan tangkap skala kecil di 30 provinsi serta penyelamatan nilai ekonomi illegal fishing sebesar 2-4 miliar dolar Amerika per tahun (Departemen Perikanan dan Kelautan, April 2004). ...

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
