Judul: Performa Reproduksi pada Induk Babi di PT Maharkata Farm Sukses Kabupaten Karo Provinsi Sumatera Utara
Abstrak: Reproductive performance needs special attention from farmers, in order to increase litter size number. This research aim to study the reproductive performance of sows. Sixty sows (40 heads secondary and 20 heads were primer data randomly used as a sample) belong to PT Maharkata Farm Sukses. The reproductive performance evaluate were age at first mating, litter size and interval between birth (calving interval) parity and birth weight. The result showed that there were no significantly different on the age of the first mating, number of litter size as well as calving interval of landrace and yorkshire landrace cross breed. The age of first mating were between 237.44±33.82 and 239.95±27.03 days. The litter size between 8.72±2.59 and 7.89±2.37 piglet respectively. The calving interval were 151.06±6.30 and 157.68±20.14 days. The result was also found that there were no difference between number of parity with litter size as well as litter size with birth weight.

Abstrak: This research was held to determine the impact of breeds and parities for the pig reproduction performance. This research has been done at pig's commercial farm PT. Adhi Farm, Solo from July until August 2005. Material that used in this research are 112 Landrace's and 43 Yorkshire's swine. The variable in this research were litter - size of born alive, lactation length, litter size of weaning, litter size of weaning percentage, mortality for suckling pigs, weaning to pregnant interval, and frequency of pregnant per sow per year. Design used in this experiment was Completely Randomized Design Factorial 2 x 4. The first factor was the breeds (Landrace and Yorkshire) and the second factor was the parity (1, 2, 3, and 4). The treatment consists of eight and each treatment was different replicated (unbalance). The statistical analysis in this experiment was ANOVA with the GLM (General Linear Model) procedure and if there were significant difference (P4.05) between the measurements, therefore could continued with the Tukey multiple comparison test.

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.
