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: 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: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
