Judul: The Reproduction Performans of Cross Boer and Kacang Goat’s “Case Study in PT. Widodo Makmur Perkasa, Province of Lampung”
Abstrak: This case study aimed as to know about management and the problems that often in the maintenance of the Cross Boer and Kacang Goat’s, pregnancy rate in the natural breeding and artificial insemination of the Cross Boer and Kacang Goat’s, to know the reproductive performance of the Cross Boer and Kacang Goat’s and to know the value of the conception rate (CR) and service per conception (S/C) from the Cross Boer and Kacang Goat’s. this study was carried on November 2007 until July in 2008, based on the method survey descriptive with the primary data collection through the interview from the employee in the PT. Widodo Makmur Perkasa, immediately observation, and the activity data in 2006-2007. The data was analysed qualitatively. The observation showed that maintenance management of the goat is good and need to improvement in feeding management and health management. Appear of pregnant in the cross Boer and Kacang Goat’s with the natural breeding higher than artificial insemination, and the value of service per conception (S/C) 1,2 and the value of the conception rate (CR) 80% in the cross Boer and Kacang Goat’s included normal showed that the artificial insemination was success.

Judul: Penampilan Reproduksi Kambing Cross Boer (Jawarandu-Boer) “Studi Kasus di PT. Widodo Makmur Perkasa, Propinsi Lampung”
Abstrak: This case study aimed at knowing the management and problems that often in the maintenance of the Cross Boer goat, identify the level of the precnancy in the natural breeding and artificial insemination, and to know the appearance of the Cross Boer goat reproduction. This study was carried on November 2007 until July 2008, based on the method survey descriptive with the primary data collection through the interview from several staff in PT Widodo Makmur Perkasa. The other data was collect from the available data in PT Widodo Makmur Perkasa. The data that was received afterwards was analysed qualitatively. The observation showed that level success of the Conseption Rate value (CR) or the level success of the reproduction by means of being natural breeding was higher (83%) compared with the Artificial Insemination method (70%). The Service per Conseption (S/C) of i natural breeding is 1,2 and the Artificial Insemination is 1,4. This data showed that S/C of Artificial Insemination is higher than Natural Breeding.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
