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: Analisis kebijaksanaan Bisnis Tuna Beku pada PT.Sumber Haslindo, Muara Baru, Jakarta Utara
Abstrak: Perairan laut Indonesia terdiri dari laut teritorial 0,3 juta km, Nusantara 2,8 juta km dan perairan ZEE seluas 2,7 juta km dengan potensi sekitar 2,1 juta ton/tahun. Potensi lestari perairan Indonesia tercatat sebesar 6.635. 826 ton/tahun yang meliputi berbagai jenis komoditi seper- ti ikan pelagis, demersal, ikan karang, ikan cakalang, ikan tuna dan udang. Selain dikonsumsi untuk memenuhi kebutuhan dalam negeri, hasil perikanan tersebut juga diolah dan dipa- sarkan untuk diekspor ke luar negeri. Selama pembangunan jangka panjang pertama ekspor perikanan Indonesia mengala- mi peningkatan 46 kali lebih banyak dalam volume dan 500 kali dalam nilai (Ditjen Perikanan, 1995). Salah satu komoditas perikanan Indonesia yang memili- ki prospek cerah dalam hal ekspor ke luar negeri adalah tuna. Pada periode 1989-1993 nilai dan volume ekspor tuna selalu mengalami peningkatan. Komoditas tuna terutama diekspor ke Jepang, USA, Filiphina dan Singapura. PT. Sumber Haslindo merupakan salah satu perusahaan perikanan yang bergerak dalam kegiatan ekspor ikan tuna ...

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
