Judul: Karakteristik Karkas dan Non Karkas Domba Ekor Tipis Betina dengan Bobot Potong yang Berbeda di TPH Maleber Bogor
Abstrak: The purpose of the research was to evaluate the characteristics of carcass and non carcass of thin-tailed sheep (DET) on different live weight in TPH Maleber, West Java. Research used 56 heads of DET ewes. The sheep grouped into live weights at 10 kg, 20 kg and 30 kg. Data were analyzed by Analysis of Variance (ANOVA). The result of the research showed that the differences of live weight were significantly (P<0.01) influenced on empty body weight and carcass weight. DET that were slaughtered at 30 kg was heavier on carcass percentage compared to 20 kg. The average percentage of carcass at live weight 10 kg, 20 kg and 30 kg was 46.09%, 42.87% and 49.56% respectively. Non carcass components of DET were slaughtered at 30 kg was significant (P<0.01) heavier than live weight of 20 and 10 kg. The percentage of edible portion of non carcass was of 42%-48% of empty body weight.

Judul: Karakteristik Karkas dan Non Karkas Domba Ekor Tipis Berdasarkan Body Condition Score di TPH Maleber Bogor
Abstrak: Body condition score (BCS) is one indicator to know high or low of fat and meat deposit on carcass and non carcass from an animal. The purpose of the research to evaluated carcass and non carcass characteristic of thin-tailed sheep (DET) on Body condition score (BCS) effect at slaughter house Maleber, Bogor. Research used 99 heads of DET. The sheep grouped into 3 group BCS, thin (1), medium (2) and fat (3) . Data were analyzed by Analysis of Variance (ANOVA). The result showed DET with BCS 3 (fat) were significant different higher live weight, carcass weight, and empty body weight from the other BCS (thin and medium). Carcass’s percentage on BCS effect showed same value from efect value of BCS 1, 2, and 3 . The differences of body condition score effect to non carcass characteristic were significantly (P<0.01) on weight and diverse on percentage whereby on the percentage of liver and rumen is different (P<0.05) but peresentase other components except heart, spleen and skin very different (P<0.01) . The percentage of weight from spleen, skin, and blood is not effected by BCS.

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.
