Judul: Identification to Confirm Death after Sheep Slaughtered
Abstrak: Kematian yang sempurna setelah penyembelihan berkaitan erat dengan aspek kesejahteraan hewan dan menjamin kualitas produk yang dihasilkan. Penelitian ini bertujuan mengidentifikasi kesempurnaan kematian pasca penyembelihan domba. Sebanyak 18 ekor domba dilakukan identifikasi selama proses penyembelihan dengan indikator yang diamati mencakup respon fisiologis saat penyembelihan serta karakteristik karkas dan non karkasnya. Hasil penelitian menunjukkan waktu rata-rata darah berhenti memancar adalah selama 149,53±27,31 detik. Darah yang keluar sebanyak 0,72±0,20 kg dengan efisiensi 4,20±0,77 %. Sebanyak 15 ekor domba mengalami proses eksanguinasi dengan baik yakni darah yang keluar menyembur dengan deras, sedangkan sebanyak 3 ekor kondisi darah menyembur tidak deras. Rata-rata waktu domba mengalami hilang reflek kelopak mata yaitu 95,31±28,14 detik, penurunan suhu terjadi setelah penyembelihan yaitu turun dari 39,40±0,44 0C menjadi 39,01±0,46 0C. Domba dengan bobot potong >20 kg memiliki bobot karkas dan bobot non karkas yang lebih tinggi dibandingkan dengan domba pada bobot potong <20 kg. Indikator terakhir telah tercapainya kematian adalah berhentinya sistem kardiovaskular yang ditandai darah sudah tidak mengalir, ternak domba yang disembelih membutuhkan waktu rata-rata hingga tercapai kematian yang sempurna selama 149,53±27,31 detik.

Judul: Waktu henti darah memancar pada penyembelihan Sapi dengan pemingsanan dan tanpa pemingsanan
Abstrak: Palpebra reflex and gushing blood downtime can be used as parameters to see animals death after slaughtered. Stop bleeding time was an indication that the heart is unable to pump blood out of the body due to no more oxygen in the blood of the heart, so that the cattle can be said has been dead perfectly. The aims of this study was to calculate the stop bleeding time of cattle slaughtered by stunning and non stunning methods, thus obtained the avaraging data of perfectly death time of animals. Thirty catlles’s Brahman Cross divided into two treatment groups, firstly 15 cattle’s were slaughtered by stunning method (group 1) and the second one 15 cattle’s were slaughtered by non stunning method (group 2). Blood gushing downtime was calculated immediately after the animal is slaughtered until the blood stops radiating. The results showed the average blood gushing downtime in cattles that were stunning before slaughtered is 3.02 minutes and the average time to stop blood gushing in cattles of non stunning group is 2.13 minutes. The interval blood gushing downtime between the cattles' slaughtered by stunning and non stunning was 53.4 seconds. Blood gushing downtime was affected by the treatment of animals before they were slaughtered.

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.
