Judul: Karakteristik dan Analisis Penjualan Karkas Non Karkas Domba Betina Lokal Berdasarkan Bangsa yang Berbeda di PT. Tawakkal.
Abstrak: Domba betina ekor tipis dan domba betina ekor gemuk merupakan bangsa domba yang banyak dipelihara oleh masyarakat. Penelitian ini bertujuan untuk mengetahui karakteristik karkas dan non karkas berdasarkan bangsa domba berbeda yang terdapat di PT Tawakkal Ternak Indonesia, Caringin Bogor. Penelitian ini menggunakan 140 ekor domba betina terdiri dari 70 ekor domba ekor gemuk dan 70 ekor domba ekor tipis. Data yang didapatkan kemudian dianalisis dengan uji t. Hasil menunjukkan bahwa dari kategori bobot potong, bobot karkas, bobot tubuh kosong, dan persentase karkas tidak berbeda nyata (P>0.05) antara domba ekor tipis dan domba ekor gemuk. Bagian non karkas yang beda nyata ditunjukkan pada bagian kaki dan saluran pencernaan. Hasil analisis juga menunjukkan bahwa persentase karkas domba ekor tipis dan domba ekor gemuk adalah 46.44% dan 45.93%. Perhitungan keuntungan penjualan karkas dan non karkas domba ekor tipis dan domba ekor gemuk berturut-turut adalah Rp123 800 dan Rp171 200 per ekor.

Judul: Karakteristik Karkas dan Non Karkas Domba Lokal Betina yang Berbeda Bangsa di TPH Maleber Bogor
Abstrak: A total of 119 local ewe which consist of 18, 76 and 25 garut sheep, thintailed sheep and fat-tailed sheep was used to evaluate the characteristics of carcass and non carcass at slaughterhouse in Maleber Bogor. The data were analyzed using Analysis of Covariance (ANCOVA), with slaughter weight as a covariable. The results showed that slaughter weight, carcass weight, empty body weight and carcass percentage among these breeds were no significantly different (P>0.05). There were no significantly differences among breeds in the weights of non carcass components, except kidney and shank. There were no significantly among breeds differences in percentage of non carcass components, except kidney percentage. In general, the garut sheep, thin-tailed and fat-tailed slaughtered at weight 20.46 kg, 15.73 kg and 15.98 kg had carcass percentages of 47.14%, 46.61% and 47.65%, and non carcass percentages of 33.56%, 32.73% and 33.32% respectively

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.
