Judul: Sistem Informasi Pengkajian Stok Ikan (Studi Kasus : Ikan Kurisi Nemipterus japonicus, Bloch 1791 di Perairan Selat Sunda yang Didaratkan Di PPP Labuan, Pandeglang, Banten)
Abstrak: Pengelolaan perikanan membutuhkan suatu informasi yang mendasar agar pengambilan keputusan dalam pengelolaan efektif dan efisien. Salah satu informasi yang dibutuhkan yaitu mengenai aspek biologi (pengkajian stok ikan). Namun saat ini masih minimnya sistem informasi mengenai perikanan terutama mengenai aspek biologi (pengkajian stok ikan) akan berakibat pada kesalahan dalam perencanaan pengelolaan perikanan (Tangke 2010). Oleh karena itu diperlukannya sistem informasi mengenai aspek biologi (pengkajian stok ikan) untuk dapat mengurangi masalah tersebut. Tujuan penelitian ini adalah untuk mengembangkan suatu program informasi CIAFISH (Calculation, Information, and Analysis of Fisheries) mengenai pengkajian stok ikan. Program ini dirancang sebagai aplikasi perangkat lunak (software) berbasis Windows dan desktop yang dikembangkan menggunakan Microsoft Visual Studio 2010 dengan bahasa pemrograman C#, XML sebagai DBMS (Database Managament System) dan Microsoft Expression Blend 4 sebagai perangkat lunak untuk desain tampilan. Data hasil penelitian Rahayu 2012 yang berjudul kajian stok sumberdaya Ikan Kurisi (Nemipterus japonicus, Bloch 1791) di Perairan Selat Sunda yang didaratkan di PPP Labuan, Pandeglang, Banten) dan data dari Dinas Kelautan dan Perikanan Provinsi Banten yang digunakan dalam uji coba program CIAFISH. Program CIAFISH bertujuan untuk mengetahui parameter hubungan panjang berat, sebaran frekuensi panjang, nilai K, L∞, dan t0, mortalitas, laju eksploitasi dan model surplus produksi (MSY, Fmsy, dan TAC).

Judul: Sistem Informasi Keberlanjutan Stok Ikan Pelagis di Perairan Selat Sunda
Abstrak: Perkembangan teknologi informasi tumbuh pesat dan berperan hampir di setiap bidang, termasuk bidang perikanan. Beberapa jenis pendataan informasi status stok ikan di wilayah pengelolaan perikanan Indonesia untuk tiap spesies ikan belum tertata secara baik. Penelitian ini bertujuan membangun suatu sistem informasi keberlanjutan stok ikan pelagis di perairan Selat Sunda yang didaratkan di PPP Labuan berbasis web. Metode yang digunakan adalah model waterfall approach dan metode skoring FSSI (Fish Sustainability Stock Index). Model waterfall approach digunakan untuk pengembangan sistem informasi. Sistem informasi berbasis web yang dihasilkan dari penelitian ini adalah sistem informasi keberlanjutan stok ikan pelagis (SI-IKAN). SI-IKAN dirancang untuk dapat menyediakan informasi terkait dengan aspek stok ikan pelagis yang berada di perairan Selat Sunda. Perhitungan nilai indeks keberlanjutan stok menunjukkan bahwa ikan pelagis telah mengalami upaya tangkap dan eksploitasi yang berlebih. Web SI-IKAN menyajikan expert program pada menu Model Produksi Surplus untuk menganalisis produksi surplus.

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
