Judul: Studi pemasaran Ikan Bandeng (Chanos Cchanos Forsk) dari Desa Tambaksari, Kabupaten Karawang Ke DKI Jakarta
Abstrak: Ikan Bandeng (Chanos chanos Forsk) merupakan produksi utama dari tambak tumpangsari di Desa Tambaksari, Kabupaten Karawang. Sebagai ikan yang tergolong ekonomis penting, ikan bandeng tersebut disalurkan oleh lembaga. pemasaran yang ada ke daerah konsumen di DKI Jakarta. Penelitian ini bertujuan untuk: (1) mengetahui gambaran umum pemasaran ikan bandeng dari Desa Tambaksari, Kabupaten Karawang ke DKI Jakarta yang meliputi saluran pemasaran, fungsi-fungsi pemasaran yang dilakukan oleh lembaga pemasaran yang terlibat dan permasalahan yang ada dalam kegiatan pemasaran tersebut, (2) mempelajari penyebaran margin pemasaran diantara lembaga pemasaran dan mengetahui besarnya farmers' share, (3) mengetahui hubungan antara farmers' share dengan total biaya pemasaran dan total keuntungan pemasaran.

Judul: Analisis Efisiensi Pemasaran Ikan Bandeng di Kecamatan Tirtajaya Kabupaten Karawang
Abstrak: Kabupaten Karawang merupakan sentra produksi ikan bandeng di Jawa Barat. Produksi ikan bandeng terus meningkat, namun harga ikan bandeng berfluktuasi. Fluktuasi harga menyebabkan ketidakpastian pendapatan baik bagi petani sebagai produsen maupun pedagang sebagai lembaga pemasaran. Fluktuasi harga sangat erat kaitannya dengan sistem pemasaran. Tujuan penelitian ini adalah mengetahui sistem pemasaran dan efisiensi pemasaran ikan bandeng di Kecamatan Tirtajaya Kabupaten Karawang. Hasil penelitian menunjukkan bahwa terdapat enam saluran pemasaran ikan bandeng di Kecamatan Tirtajaya, Kabupaten Karawang. Lembaga pemasaran yang terlibat didalamnya antara lain petani, pedagang pengumpul desa, pedagang besar, pedagang pengecer dan pengolah. Dilihat dari nilai marjin pemasaran dan farmer’s share, seluruh saluran pemasaran ikan bandeng sudah efisien. Dari seluruh saluran pemasaran, saluran pemasaran 1 merupakan saluran yang relatif lebih efisien dengan nilai marjin terendah sebesar 9.71 persen dan farmer’s share tertinggi sebesar 90.29 persen. Nilai rasio keuntungan atas biaya pada seluruh lembaga pemasaran telah menyebar secara merata.

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
