Judul: Pengaruh pregnant mare serum gonadotrophin terhadap kebuntingan dan jumlah anak kambing jawarandu yang berahinya diserentakan dengan progesteron
Abstrak: Kambing Jawarandu adalah kambing Indonesia, yang berpotensi besar untuk dikembangkan di daerah pedesaan karena bersifat dwi-guna (produksi daging dan air susu}. Pemeliharaannya mudah dan modal yang digunakan relatif sedikit. Disamping itu sumbangan kambing Jawarandu dapat membantu mencukupi kebutuhan protein hewani kita, terciptanya lapangan kerja dan meningkatkan pendapatan peternak. petani Menurut Sabrani dkk. (1982) kambing yang persentase darah Etawahnya makin tinggi, jumlah anak perkelahiran rendah dan lambat menjadi dewasa. Sedang Setiadi dan Sitorus (1986) mengatakan bahwa kambing Jawarandu mempunyai jumlah anak perkelahiran lebih rendah dibanding kambing kacang. Rendahnya jumlah anak yang dilahirkan, bukan hanya disebabkan oleh sedikitnya Jumlah kelahiran, tetapi Juga d sebabkan oleh kegagalan pembuahan, kematian embrio baik sebelum maupun sesudah dilahirk:an ( Singh at a.l 1986) . meningkatkan Jumlah kelahiran dapat digunakan Pregnant

Judul: Penampilan reproduksi kambing jawarandu (Studi kasus di PT Widodo Makmur Perkasa, Propinsi Lampung)
Abstrak: lhis study aimed to learn the reproduction perjonn of Jawarandu goat for the increase in the population cover the aspect of Conception Rate (CR), Service per Conception (S/C), as well as problems that open in the maintenance from 50 Jawarandu goat that consists of 41 heads in natuml breeding and 9 heads in Artrficial Insemination. Method in this study used of descriptive method, and primary data collection through interview with several st& in PT Widodo Makmur Perkasa and secondary data obtained from the available data in PT Widodo Makmur Perkasa, some literature, and the internet. The observation showed that the level success of the reproduction or Conception Rate (CRJ of natural breeding is higher than Artrficial Insemination that is of 82,93% in natural breeding and 66,67% in Artrficial Insentination. The Service per Conception (S'C) of natural breeding is 1,2 and the Artificial Insemination is 1,5. The data showed that S/C of ArhJicial Insemination is higher than natural breeding. The problems that o$en in the maintenance of the Jawarandu goat that is premature, born small, the young goat can't survive because the condition the body too weak, and the fracture.

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.
