Judul: Penggunaan intercom untuk mendukung keberhasilan pelaksanaan program inseminasi buatan pada sapi potong
Abstrak: Keberhasilan pelaksanaan program IB pada peternakan. rakyat ditentukan oleh berbagai faktor, antara lain kesuburan betina, kualitas semen dan keterampilan kerja inseminator disamping pengetahuan dan pelaporan berahi oleh peternak. Faktor lain yang juga sangat penting diperhatikan adalah ketepatan waktu pelayanan IB, sebab sperma yang diinseminasi harus dapat bertemu dengan ovun pada waktu yang tepat supaya terjadi konsepsi.

Judul: Evaluasi Keberhasilan Pelaksanaan Program Inseminasi Buatan (IB) pada Sapi Potong di Kota Sawahlunto
Abstrak: Study in investigating the technical and socio-economic conditions that may affect the successful implementation of Artificial Insemination (AI) program were done in Sawahlunto July 2011 to September 2012. This study was conducted through interviews with survey methods in the form of questionnaires to 44 farmers and 16 inseminators. This study aimed to determine the factors that could affect the successful implementation of the AI program. The results of the study showed that most farmers had low level of education and experience. Raising beef cattle only as a side job, with the majority of main jobs as farmers and cattle ownership below 5 heads. Animal husbandry technique applied by most breeders was a semiintensive and a small portion was applied extensively. Experience of inseminator on duty was low and half of inseminator did not have a License in Performing Artificial Insemination (SIMI). Working system of inseminator has been performed well, but the working capability still less. The success rate of implementation of the AI program were assessed from the number of services per conception (S/C) and conception rate (CR) had been good, but the value of calving interval (CI) still low. Factors that influence the success rate of implementation of the AI program was raising experience and farming system which in use, while the level of education and participation of farmers had no effect

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.
