Abstrak: Mackerel tuna is one of the commodities that are targeted by fishermen catchment of Anambas Island District. This is because the mackerel tuna is an important economic fish in Anambas Islands District. The production of the catch in Anambas Islands District in 2015 was 7497.8 tons and 20% of the total catch was a tuna. The marketing of mackerel tuna in Anambas includes the Anambas Islands district and the surrounding big cities such as Tanjung Pinang and Batam, not including inter-provincial or export markets. This study aims to analyze the patterns of marketing channels of mackerel tuna, marketing functions and marketing institutions involved, and to know the marketing efficiency of tuna by marketing margin and fisherman's share. This research was conducted in Tebang Village, Palmatak District, Anambas Islands Regency. The research was conducted in March 2016. The data collection method used in this research is triangulation. Informants and respondents were determined by purposive sampling and snowball sampling techniques. Respondents who are determined in this study are fishermen and the Department of Marine and Fisheries Anambas Islands District. Channel marketing channels in Anambas Islands involve fishermen, collecting traders, retailers and end consumers. The highest margin occurred in collecting merchants with the value of Rp 15.000 per kg, the percentage of 60% and the lowest was in the local market traders and the long-distance market with the value of Rp 5,000, the percentage of 17% and 33%. The most efficient marketing channel for tuna is first marketing channel.

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: 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.
