Judul: Implikasi kebijakan perbibitan sapi terhadap adopsi inovasi inseminasi buatan pada peternak sapi potong
Abstrak: The general objective of the research is to describe and analyze the implementation and rate of adopted artificial insemination (AI) innovation on slaughter cattle’s farmers. The result showed that the internal, external and bussiness farm characteristic of slaughter cattle’s farmers and their perception on AI were signifcantly different among the locations of the research. The average of AI implementation by the farmers was 51.1%. There were significant different of average implementation of AI aspects among all locations. The average of the rate of AI adoption was 2.39 years. There are significant different between locations where the cross breeding policy have been applied (Lamongan and Bangkalan districts) and the location where the pure breeding policy have been applied (Tabanan district). In adoption of AI, the farmers in the Tabanan district were relatively faster than other districts. Based on the result of structural equation modelling analysis, the relationship among variables were (1) the variables of internal characteristic of slaughter cattle’s farmers and their perception to AI significantly influenced to the implementation of AI, but the variables of external and farm bussiness characteristic of slaughter cattle’s farmers did not significantly influence to the implementation of AI. The variable of the perception of the farmer to AI contributed to the implementation of AI relatively bigger than the internal characteristic of slaughter cattle’s farmers variable; (2) the variables of internal, external and farm bussiness characteristic of slaughter cattle’s farmers and their perception to AI significantly influenced to the rate of AI adoption. The most influence variable to the rate of AI adoption was the external characteristic of slaughter cattle’s farmers; (3) the perception of slaughter cattle’s farmers on AI influenced both to the implementation of AI and to the rate of AI adoption; (4) cumulatively, the influence of the internal, external, farm bussiness characteristics of slaughter cattle’s farmers and their perception to AI implementation aspects and to the rate of AI adoption was 0.51 (51%) and 0,86 (86%) respectively. The implementation of AI as an instrument to achieve breeding policy’s purposes on slaughter cattle did not give yield yet as it was hoped. This case was caused by the breeding policy on slaughter cattle still have not clear and the implementation of the AI in the field have not been controlled.

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: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
