Judul: Pengaruh bangsa dan paritas terhadap penampilan reproduksi ternak babi di usaha peternakan babi PT. Adhi farm, Solo
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: Pengaruh Sistem Pengawinan(Alami dan IB)< Paritas dan Frekuensi Pengawinan terhadap Laju Kebuntingan Ternak Babi di Usaha Peternakan Babi PT. Adhi Farm, Solo
Abstrak: Penelitian ini dilakukan di usaha peternakan babi PT. Adhi Farm, Solo, Propinsi Jawa Tengah. Penelitian dilaksanakan pada awal bulan Juli sampai dengan akhir bulan Agustus 2005. Latar belakang dari penelitian ini adalah ternak babi memiliki daya reproduksi dan litter size yang tinggi jika dibandingkan dengan ternak lain seperti sapi, domba, kerbau dan kuda. Tujuan penelitian adalah untuk mengetahui pengaruh dari sistem pengawinan (alami dan IB), paritas dan frekuensi pengawinan terhadap laju kebuntingan ternak babi di usaha peternakan babi PT. Adhi Farm, Solo. Teknik pengumpulan data dilakukan dengan dua cara yaitu primer dan sekunder. Data primer diperoleh dari pengamatan langsung yang meliputi penampungan semen, evaluasi semen, pengawinan secara alami dan IB serta pemeriksaan kebuntingan. Data sekunder diperoleh dari catatan induk babi. Materi yang digunakan adalah 56 ekor babi betina, 10 ekor pejantan (data primer) dan 116 ekor induk babi (data sekunder).

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.
