Judul: Alternatif pola bagi hasil nelayan gillnet di Muara Baru, Jakarta Utara
Abstrak: Bagi hasil merupakan salah satu cara yang dilakukan pemilik kapal untuk membagi hasil tangkapan dengan nelayan buruh. Pembagian proporsi yang selama ini terjadi adalah sepenuhnya sesuai kehendak pemilik kapal. Hampir tak ada peluang bagi nelayan buruh untuk mengajukan proporsi yang lebih adil. Nelayan buruh hanya menjadi pihak yang selalu menerima setiap keputusan pemilik kapal. Hal ini dikarenakan nelayan buruh tidak memiliki penguasaan kapital yang tinggi terhadap usaha Gillnet sehingga meyebabkan posisi tawar nelayan buruh menjadi rendah.

Judul: Analisis mata pencaharian alternatif nelayan gillnet di Desa Batukaras, Kecamatan Cijulang, Pangandaran, Jawa Barat
Abstrak: Fishermen in Batukaras generally using bottom set gillnets. Activities of fishing operations using the hunting system and depend on the season. The purpose of this study is to describe the gillnet fishing unit and analyze the work done by the fishermen, both fisheries and alternative livelihoods (non-fisheries). The method of this research using survey methods and data collection techniques by purposive sampling. Analysis of the data used in the form of analysis of fishing unit and financial analysis that includes the analysis of income and revenue cost ratio (R/C). The results of the analysis of fishing unit showed that gillnet construction consist of buoys, head and ground ropes, net body, neck strap, and sinker. Gillnet was operated by 2-3 fishermen using the boat which its length (L) 9.00 meters, breadth (B) of 1.50 meters, and depth (D) 1.00 meters. The work done by gillnet fishermen is fisheries effort and alternative livelihoods. Based on the financial analysis has result that average of fishermen income is Rp 693.297 per month and the value of R/C of 1.31 (R/C> 1), so fisheries effort is profitable and feasible to be developed. alternative livelihoods undertaken by the fishermen including agriculture, albizia wood cultivation, collecting firewood, collecting coconuts, used goods sellers, kiosk, and gardening cardamom. Based on the financial analysis has result that average of alternative livelihoods is Rp 445.347 per month and the value of R/C obtained from all alternative livelihoods is more than one, so the alternative livelihoods businesses profitable and feasible to be developed. This is supported by the result of the pattern of business implementation, in which all alternative livelihood done on famine and moderate, so it does not interfere the main work of the fishermen.

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.
