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: Evaluasi Keberhasilan Pelaksanaan Program Inseminasi Buatan (IB) Sapi Potong di Provinsi Kalimantan Selatan
Abstrak: Meningkatnya permintaan daging sapi oleh konsumen tidak diimbangi dengan jumlah populasi sapi potong di Indonesia. Kegiatan Inseminasi Buatan (IB) di Indonesia terus dilakukan guna meningkatkan populasi, mutu, dan produksi ternak sapi. Penelitian ini bertujuan untuk mengetahui tingkat keberhasilan IB melalui evaluasi pelaksanaan program IB di Provinsi Kalimantan Selatan dilihat dari service per conception (S/C) dan conception rate (CR). Data yang digunakan merupakan data sekunder yang diperoleh dari Dinas Perkebunan dan Peternakan Provinsi Kalimanan Selatan dalam kurun waktu 2011-2015, meliputi target dan realisasi pelaksanaan IB, target dan realisasi kelahiran, serta perhitungan S/C dan CR. Data yang terkumpul dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa rataan S/C dan CR dari tahun 2011-2015 berturutturut 1.5 dan 66.4, 1.12 dan 63.1, 2.0 dan 64.9, 1.6 dan 67.6, 1.7 dan 66.3. Dapat disimpulkan bahwa pelaksanaan program IB di Kalimantan Selatan masih berada dalam pencapaian skala nasional.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
