Judul: The marketing efficiency analysis of fisheries result at pangkalan pendaratan ikan muara angke, dki jakarta
Abstrak: Potensi rata-rata hasil perikanan tangkap adalah sekitar 6,5 juta ton/tahun dengan tingkat pemanfaatan pada tahun 2011 mencapai 5,71 juta ton. Tempat Pelelangan Ikan (TPI) memiliki peran sentral sebagai pusat pemasaran. Tujuan dari penelitian ini adalah untuk mengetahui peranan TPI dalam pemasaran hasil perikanan tangkap, mengetahui saluran pemasaran hasil perikanan tangkap yang terjadi di TPI dan bukan TPI, dan menganalisis tingkat efisiensi pemasaran. Metode pengumpulan data melalui kuesioner dan wawancara terstruktur. Penentuan responden menggunakan accidental sampling (convenience sampling) untuk nelayan, dan snowball sampling untuk lembaga pemasaran berikutnya. Hasil penelitian menemukan TPI memiliki peran penting dalam hal pemasaran ikan. Tidak ada saluran pemasaran yang mutlak efisien. Namun, jika dilihat dari nilai total margin yang rendah, fisherman’s share yang tinggi dan biaya pemasaran yang rendah maka saluran pemasaran 3 pada sistem lelang murni cenderung lebih efisien. Tapi jika dilihat dari nilai rasio keuntungan dan biaya yang relatif sama pada setiap lembaga pemasarannya maka saluran pemasaran 1 pada sistem lelang murni dan saluran 3 pada sistem opow cenderung lebih efisien., The potential average of fisheries yield is about 6.5 million tonnes / year by the utilization rate in 2011 reached 5.71 million tons. Tempat Pelelangan Ikan (TPI) has a central role as a marketing center. The purpose of this research was to determine the role TPI in the marketing of fisheries, to knows marketing channel of fisheries yield in TPI or not, and to analyze the level of marketing efficiency. Methods of data collection through questionnaires and structured interviews. Determination of the respondents using simple random sampling for fisherman, and the next marketing institution using snowball sampling. The results of this research shows TPI has an important role in the marketing of fish. There is no absolute efficient marketing channels. However, if viewed from the total value of low margin,fisherman's share of high,and marketing cost of low, marketing channel 3 on a pure auction system is tends to be more efficient. But when viewed from the cost profit ratio with same relative value at each institution marketing, the marketing channel 1 on a pure auction system and the marketing channel 3 on opow systems is tend to be more efficient.

Judul: Efisiensi Pemasaran Ikan Tangkap di Pelabuhan Perikanan Nusantara (PPN) Palabuhanratu Kabupaten Sukabumi
Abstrak: Produksi ikan laut di PPN Palabuhanratu mengalami fluktuasi setiap tahunnya. Rata-rata harga ikan tingkat produsen di PPN Palabuhanratu umumnya masih rendah, ditambah ikan termasuk komoditas yang mudah rusak (perishable). Penelitian ini bertujuan untuk menganalisis efisiensi pemasaran ikan tangkap di PPN Palabuhanratu, khususnya jenis ikan tuna madidihang. Metode yang digunakan yaitu metode purposive sampling, metode accidental sampling dan metode snowball sampling. Jenis data yang digunakan adalah data primer dan sekunder. Metode analisis data yang digunakan adalah margin pemasaran, farmer’s share, dan rasio keuntungan terhadap biaya. Hasil penelitian menunjukkan bahwa terdapat empat saluran pemasaran yaitu saluran pemasaran I (nelayan-pedagang besar-konsumen), saluran pemasaran II (nelayan-pedagang besar-pedagang lapak-konsumen), saluran pemasaran III (nelayan-pedagang lapak-konsumen) dan saluran pemasaran IV (nelayan-pedagang lapak-pedagang bermotor-konsumen). Saluran pemasaran III (nelayan-pedagang lapak-konsumen) merupakan saluran pemasaran yang relatif efisien dibandingkan dengan saluran lainnya, karena memiliki nilai margin terkecil sebesar Rp. 13.439, nilai farmer’s share tertinggi sebesar 65,52 persen dan nilai π/c sebesar 16,30., Production of sea fish in PPN Palabuhanratu fluctuates every year. The average price of fish in PPN Palabuhanratu is generally still low and fish is a perishable commodity. This study aims to analyze the marketing efficiency of catching fish in PPN Palabuhanratu, especially the type of madidihang tuna. The methods used are purposive sampling method, accidental sampling method and snowball sampling method. The types of data used are primary and secondary data. The data analysis methods used are marketing margin, farmer's share, and profit to cost ratio. The results showed that there are four marketing channels, there are marketing channel I (fishermen-wholesalers-consumers), marketing channel II (fishermen-wholesalers-stall traders-consumers), marketing channel III (fishermen-stall traders-consumers) and marketing channel IV (fishermen-stall traders-motorized traders-consumers). Marketing channel III (fisherman-stall merchant-consumer) is a relatively efficient marketing channel compared to other channels, because it has the smallest margin value of Rp. 13,439, the highest farmer's share value of 65,52 percent and the value of profit to cost ratio of 16,30.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
