Judul: Perancangan sistem informasi perikanan berbasis web di Kepulauan Seribu DKI Jakarta
Abstrak: Ketersediaan data dan informasi mengenai sumberdaya perikanan di Indonesia masih jauh dari sempurna. Tersedianya data dan informasi yang lengkap merupakan salah satu penunjang dalam keberhasilan pembangunan perikanan di Indonesia. Daerah Kepulauan Seribu yang terdiri atas banyak gugusan pulau menyimpan banyak kekayaan sumberdaya perikanan yang belum terdata secara lengkap. Penelitian ini berusaha untuk mengetahui keadaan umum perikanan di Kepulauan Seribu serta bagaimana menciptakan suatu sistem informasi yang dapat menampilkan data-data serta informasi perikanan yang lengkap untuk daerah Kepulauan Seribu Hasil dari penelitian ini adalah terciptanya suatu model sistem informasi perikanan berbasis web yang didalamnya terdapat potensi-potensi perikanan daerah Kepulauan Seribu…

Judul: Sistem Informasi Sebaran Ikan Ekonomis Penting di Indonesia Berbasis Web
Abstrak: Regulations of the Republic of Indonesia Number 45 of 2009 stated that government and local government have to establish information system of fisheries so that the fisheries information can be easily and quickly accessed by the community. However, in particular information systems of fisheries that contain distribution and statistical data of economically important fishes in Indonesia are still less than optimal. The purpose of this research is to build the application of information system that contains the spatial distribution of economically important fishes in Indonesia and to determine the distribution of shrimp, tuna, skipjack tuna and bullet tuna based on statistical data of marine capture fisheries. The result of this study is web-based application called Information System of Distribution of Economically Important Fishes in Indonesia. This application can be accessed at http://siikan.site90.net. The main information presented in this application is time series of fisheries statistical data from 2003 to 2011 based on province in Indonesia. Through this information system, it can be seen that the shrimp, skipjack tuna and bullet tuna are found in all provinces in Indonesia, while the tuna are not found in the province of Riau, Riau Islands, Bangka Belitung Islands, Jambi, South Sumatra, and Central Kalimantan.

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
