Judul: Analisis finansial usaha pembenihan ikan nila gift di Desa Caringin Wetan kecamatan Caringin, Kabuaten Sukabumi, Provinsi Jawa Barat
Abstrak: Kabupaten Sukabumi memiliki potensi yang besar dalam budidaya perikanan air tawar, khususnya ikan konsumsi, poterisi tersebut masih memiliki peluang yang besar untuk ditingkatkan lagi pemanfaaiannya karena tingkat pemanfaatan lahan perikanan di Kabupaten Sukabumi masih tergolong rendah. Desa Caringin Wetan merupakan salah satu desa yang berada di Kecamatan Caringin Wetan Kabupaten Sukabumi. Desa Caringin Wetan memiliki keadaan alam yang mendukung bagi usaha pembenihan Ikan Nila Gift. Potensi alam yang baik ini dapat dimanfaatkan secara optimal bagi usaha pembenihan Ikan. Nila Gift.

Judul: Prospek pengembangan usaha pembesaran ikan nila gift pada kolam air deras di Desa Cijambe, Kecamatan Cijambe, Kabupaten Subang
Abstrak: Kecamatan Cijambe merupakan salah satu kecamatan di Kabupaten Subang yang memiliki potensi perikanan kolam air deras yang sangat baik, terutama Desa Cijambe dengan letak lokasi usaha budidaya yang strategis dan unggul, Komoditas unggulan Kecamatan Cijambe adalah ikan Mas, namun karena kondisi air sungai yang mengandung penyakit aeromonas menyebabkan kematian pada ikan Mas. Guna mengefisienkan kolam air deras di Desa Cijambe dan melihat besarnya pangsa pasar maka dikembangkanlah ikan Nila Gift. Sebagai komoditas yang baru dikembangkan belum mampu memenuhi pangsa pasar yang besar, dengan demikian perluasan usaha pembesaran ikan Nila Gift akan diperoleh keuntungan. Besarnya kentungan yang diperoleh dapat dikaji melalui analisis usaha, analisis kriteria investasi dan analisis sensitivitasnya. Tujuan dari penelitian ini adalah untuk menelaah kegiatan usaha pembesaran ikan Nila Gift, menganalisis kriteria investasi dan sensitivitas usaha pembesaran ikan Nila Gift di Desa Cijambe. Metode penelitian yang digunakan adalah studi kasus dengan metode pengambilan sampel berupa purposive sampling. Perhitungan analisis usaha meliputi analisis pendapatan usaha dan analisis imbangan penerimaan dan biaya (R-C ratio), sementara analisis kriteria investasi meliputi Net Present Value (NPV), Net Benefit-Cost Ratio (Net B/C) dan Internal Rate of Return (IRR). Analisis sensitivitas dipengaruhi oleh peningkatan harga pakan ikan Nila Gift sebesar 15,02% dan harga benih ikan Nila Gift sebesar 17,24% Sementara itu, pengkajian terhadap prospek pengembangan usaha meliputi peluang dan kendala pada aspek teknis, aspek alam, aspek finansial, aspek sarana dan prasarana, aspek pemasaran, serta aspek sumberdaya manusia. Perhitungan analisis usaha menunjukan bahwa usaha pembesaran ikan Nila Gift dengan kepemilikan rata-rata 20 unit kolam lebih menguntungkan daripada kepemilikan rata-rata 8 unit kolam. Berdasarkan perhitungan analisis kriteria investasi dan analisis sensitivitas, usaha pembesaran ikan Nila Gift di Desa Cijambe dinyatakan layak untuk diusahakan selama umur proyek

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
