Judul: Analisis Risiko Usaha Perikanan Tangkap Skala Kecil di Palabuhanratu
Abstrak: The number of Indonesia’s small scale fishing is huge and growing up, however commonly fisherman’s welfare still below the poverty line. Capital resistance access is one of restrictively factor to the condition. Besides banking system put fisheries capturer activity as a high risk and indeterminancy. Based on the situation we intend to do research for describing the risk of comprehensive small scale fisheries capturer in Palabuhanratu, include in offering a solution. The aim can be approach by several activity, (1) identify and address the risk of fisheries capturer activity, (2) calculate the risk and impact of production, price and income, (3) calculate the fisherman’s attitude about the risk, (4) design an easy solution for the fisherman to get the business capital. The research was held in October 2006 until March 2007 in Palabuhanratu District, Regency of Sukabumi, the data collected and analyzed using descriptive method, deviation standard, variation coefficient, PRT and SWOT. Based on the result we know that risk in small scale fisheries capturer activity generally consist of (1) loose or damage in piscatorial facilities, (2) ineffective of capturing operation and, (3) threat of fisherman safety. Palabuhanratu fisherman tend the act by not to take the risk (risk averter). There are 3 priority solutions for the problem regarding capital accessibility. There are (1) implementing flexible loan regulation which is still in prudential, (2) create a law of capital strengthening, (3) enacting financing scheme suitable with fisheries capturer characteristics

Judul: Penilaian Unit Penangkapan Pancing Rumpon di Palabuhanratu, Kabupaten Sukabumi, Jawa Barat
Abstrak: Tuna total production with rod fishing increase 0.73% in 2011, and total of rod fishing unit increase 1.55% in the same time. Technical and economical analysis must be done for we know how the feasibility of rod fishing unit’s business. The objective of the research is to describe the rod fishing unit, to calculate the benefit, and the investment of rod fishing unit’s business in Palabuhanratu waters. The research is case study of rod fishing unit’s business. Data analysis used description, technical and financial analysis. There are four types of rod fishing, those are troll fishing, pancing jerigen, pancing layanglayang and hand line. The rod fishing is not difficult in operation. Business of the rod fishing unit can give a profit Rp 67,245,500.00 and payback period is 4.2 years. The value of NPV is more than 0 (zero), Net B/C is more than 1 and IRR is more than value of interest rate. The business of rod fishing unit is not sensitive to the fuel’s price increasing. The decision makers can help the fishermen to improve their capital from finance institution, and do the detail technical analysis about rod fishing unit operation and its influence to stock equilibrium

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.
