Abstract

Pengencer semen babi telah banyak diteliti dan dikembangkan untuk mendukung program Inseminasi Buatan (AI). Dalam proses pengenceran semen babi, tersedia berbagai macam pengencer dengan berbagai merk dan harga di pasaran. Dalam memilih pengencer ini, kandungan nutrisi dan daya simpan menjadi pertimbangan. Beberapa pengencer yang tersedia perlu diketahui kualitasnya dalam menjaga kualitas sperma babi. Berdasarkan hal tersebut, perlu dilakukan uji coba terhadap berbagai produk pengencer semen babi yang beredar di pasaran. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan empat perlakuan dan empat ulangan. Perlakuan yang diuji pada penelitian ini adalah penggunaan pengencer MIII, Biopig, Semenlife dan VIM. Pengencer dilarutkan dalam aquades sesuai dengan instruksi dari produsen pengencer. Semen babi yang digunakan dalam penelitian ini berasal dari babi jenis Yorkshire. Parameter yang diukur pada penelitian ini adalah motilitas, viabilitas dan abnormalitas spermatozoa. Pengamatan dilakukan 12 jam setelah pengambilan semen segar. Data yang diperoleh diolah dengan analisis varians (ANOVA) menggunakan Software SAS 9.1. Hasil penelitian menunjukkan bahwa penggunaan pengencer yang berbeda tidak memberikan pengaruh nyata (P>0,05) terhadap motilitas, kelainan dan viabilitas sperma babi yang disimpan selama 12 jam. Motilitas dan viabilitas sperma pada penelitian ini tidak berbeda dengan penelitian sebelumnya, namun abnormalitas sel sperma hampir dua kali lebih tinggi dibandingkan penelitian sebelumnya. Meskipun demikian, pengencer Semenlife menunjukkan motilitas dan abnormalitas yang lebih baik.

Abstract

Mirah chickens are Indonesian indigenous chickens that originate from Simalungun Regency, North Sumatera Province of Indonesia. The study aimed to determine the genetic characterization of Mirah chicken based on the mitochondrial D-loop region (838 bp). Twenty Mirah cocks from Simalungun Regency of Indonesia were used in the present study. The results showed that fourteen haplotypes were found in the studies of birds based on sixteen mutation sites. Therefore, these haplotype and nucleotide diversities in the partial D-loop region of the Mirah chicken were classified as high. The Median-joining tree revealed that the Mirah chickens were classified in a similar cluster with the Red jungle fowl (Gallus gallus). Ten haplotypes of birds were close to G. g. bankiva, and four haplotypes of birds were close to G. g. gallus. In conclusion, Mirah chickens had the genetic introgression from two sub-species of Red junglefowl, i.e., G.g. gallus and G.g. bankiva. Hence, the pure breeding program for Mirah chickens is important to conserve their genetic resources from extinction.

Abstract

Kuliah Praktek Pengabdian pada Masyasyarakat (KPPM) merupakan salah satu bentuk pengabdian mahasiswa terhadap masyarakat. Lokasi pengapdian di lakukan di desa parparean I, Sebagai desa yang masih berkembang, desa parparean I memiliki sumber daya alam yang dapat dimanfaatkan untuk meningkatkan kesejahteraan masyarakat terutama dalam sektor pertanian perikanan dan pariwisata. Namun desa ini juga memiliki kekurangan, kurangnya pemberdayaan para petani terhadap sumber daya alam yang ada, termasuk pada buah kakao. Harga yang tidak stabil sering kali menjadi penyebab utama. Ketika harga turun drastis, petani tidak termotivasi untuk memanen karena biaya panen dan transportasi bisa melebihi pendapatan yang diperoleh. Oleh karena itu keterlibatan mahasiswa dalam kppm di desa parparean I dapat memberikan konstribusi positif dalam mengatasi serta mengoptimalkan permasalahan desa Parparean I.
