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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
