Judul: Pencarian Varian Gen Miostatin Pada Domba Komposit Sumatera
Abstrak: Domba komposit sumatera merupakan bentuk silangan domba lokal ekor tipis Sumatera (DETS) dengan domba St. Croix (SC) dan Barbados Blackbelly (BB) dengan komposisi 50% DETS: 25% SC: 25%BB (Subandriyo et al. 2000). Miostatin atau growth differentiations factor 8 (GDF 8) merupakan anggota dari superfamili transforming growth factor-â (TGF-â) berfungsi sebagai pengontrol negatif pertumbuhan otot (McPherron et al.1997). Mutasi gen miostatin dapat mengganggu ekspresi dan aktifitasnya sehingga otot kerangka akan mengalami hipertropi ataupun hiperplasia (pertumbuhan otot yang melebihi normal), hal ini dikenal dengan fenomena double muscling. Mutasi pada makhluk hidup dapat terjadi secara alami dalam jangka waktu yang panjang, sehingga menghasilkan varian-varian baru dari makhluk hidup tersebut. Hasil pencarian varian gen miostatin pada domba komposit sumatera menggunakan dengan metode PCR-RFLP dengan enzim restriksi Hae III dan Mbo I tidak menunjukkan adanya keragaman. Metode PCR-SSCP menunjukkan adanya varian gen miostatin ekson 3 pada domba komposit dalam penelitian ini yaitu W, X, Y, dan Z dengan frekuensi berturut-turut 3.62 %, 37.35 %, 37.35 %, dan 21.69 %. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa tipe SSCP gen miostatin ekson 3 tidak nyata mempengaruhi tipe kelahiran, bobot lahir, bobot sapih, dan pertambahan bobot badan pada domba komposit sumatera.

Abstrak: Myostatin is a member of tranforming grown factor B superfamily, know as growth and differentiation factor, which is essensial for proper regulation of skeletal muscle mass in wide range vertebrate species. To pursue potential agricultural application of increasing muscle mass by inhibition of myostatin activities, the aim of this study was to identify the variants of myostatin gene in the Indonesian local sheeps. A total of 151 DNA samples belonging to eight different areas that are Bogor Ciomas (20), Bogor Jonggol (35), Margawati (18), Indramayu (30), Dinggala (24), MAdura (8), Sumbawa (8), and Rote (8) were analyzed with Polymerase Chain Reaction-Single Starnd Conformation Polymorphism. The Myostatin (GDF 8) amplified product was 688 bp(base pair)

Abstrak: Information Literacy (IL) Program is a library program that aims to improve the ability of library users to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information. Information literacy learning is essential to be taught and applied in education from the beginning of the school so that students are able to find and organize information effectively and efficiently particularly regard to the school assignment and learning process. At present, various educational institutions began to implement online learning model to improve the quality of teaching and research quality. Due to the advancement of information technology, the information literacy program should be adjusted with the needs of library users. The purpose of this study was to design web-based information literacy learning for school library. This research conducted through several stages which are: identifying the needs of web-based IL, designing web-based IL, determining the model and the contents of a web-based IL tutorial, creating a prototype webbased IL, testing, and usage tutorial prototype IL. The results showed that 77% of respondents stated the need of web-based learning IL. The prototype of web-based learning IL is consisted of six main units using combination of the Big6 Skills model and 7 Concept of Information Literacy by Shapiro and Hughes. The main sixth units are Library Values, Literacy Resource, Literacy Research, Organization of Information, Critical Literacy and Publishing Literacy. In testing phase the prototype of IL web-based worked properly. After passing the test, the prototype of IL web-based could be used through hyperlink in web school network. This prototype web-based information literacy is expected to support the information literacy learning in a holistic approach.
