Judul: Development Analysis on Gillnet Fisheries in Karangantu Waters, Serang District - Banten Province
Abstrak: Research on gillnet fisheries in Karangantu waters of Serang District has been conducted from November 2005 to April 2006. This research was aimed to : 1) Identifying factors influencing the gillnet productivity, 2) Analysing economic performance of the gillnet fisheries and 3) Formulating alternative policies on gillnet fisheries development in the area. Data collecting was carried out trought purposive sampling of respondents, interviewing by using prepared questionnares, with using descriptive and survey method. Cobb-Douglas ( Soekartawi, 1999) method was used to determine the factors influencing the gillnet productivity. SWOT analysis ( Mulyono, 1996) and Analytical Hierarchy Process, AHP ( Saaty, 1993) were used for the formulation of the policies. Result of the research shows that from seven independent factors, the net size was indicated to be the most factors influencing the gillnet fisheries productivity. The production model of Cobb-Douglas was Y=0,31-0,041X1+0,78X2+0173X3- 0,0453+0,057X5+0,83X6-0,472X7 with its accuracy data 95% and determinant factor 83,3%. Gillnet fisheries in Karangantu is most dominantly used and show profitable performance (BEP Rp.10.915.000,-/year at the production volume of 4.461 kg/year, net B/C value 1,54, NPV Rp. 54.738.293,- and IRR 74,49%). The earnings of gillnet fishers is above Serang District regional minimum wage rate (2005). The following development strategies were recommended: 1) Controlling the number of fishing gear and fishing effort, 2) Arrangement and controlling the fishing ground (DPI) based on fishing gear and increasing the security assurance, 3) Skill improvement for the gillnet fishers, providing capital investment and marketing, 4) Increasing the size of fishing boat and gillnet size, accurate and timely statistic data are desperately needed.

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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
