Judul: Aktivitas Pendaratan dan Pemasaran Hasil Tangkapan di Pangkalan-Pangkalan Pendaratan Ikan Kabupaten Ciamis
Abstrak: Marine fisheries activities at Ciamis Regency is supported by the fishing landing bases (PPI) spread out over 5 sub-district. Some of the activities in these PPI are landing and marketing of fish catches. Both of these activities require adequate facilities and careful handling because fish is a perishable commodity. The purpose of this research are to know the actual condition of the fishing ports, the activity of landing and marketing of fish catches in 5 locations of PPI at Ciamis Regency. This research used the survey method and descriptive data analysis. The results showed that fishing port facilities in 5 locations of PPI at Ciamis Regency is still very lacking. All of PPI at Ciamis Regency uses beach and estuary of the river as a place for landing of the fish catches. PPI Batu Karas has the most of number and volume of landing fish catches than the others. The fishes landed on all of PPI at Ciamis Regency are marketed through the fish-trading activity, except at PPI Pangandaran. The fishes are marketed for consumption of local communities around the PPI, inside and outside of the Ciamis Regency. Some types of fish that has high economic value such as shrimp, lobster and hairtails are exported to Japan, China and South Korea. NP/P ratio and relative value of production index gained PPI Kalipucang in 2010 is bigger than the others. This is because the fish were landed at this PPI are homogeneous, consisting only of lobster that has high economic value.

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.
