Judul: Korelasi antara Umur dengan Bobot Badan dan Body Condition Score (BCS) di Pedagang Lapak Hewan Kurban di Daerah Lampung
Abstrak: Bobot badan dan Body Condition Score (BCS) ternak merupakan indikator yang sangat penting dalam pemilihan hewan kurban. Penelitian ini bertujuan menganalisa hubungan umur dengan bobot badan dan BCS pada hewan kurban. Jenis dan jumlah hewan kurban yang digunakan adalah 10 ekor sapi, 8 ekor domba dan 333 ekor kambing dengan peubah yang diukur dan diamati berupa bangsa ternak, umur ternak, bobot badan ternak, dan BCS ternak. Hubungan antara umur dengan bobot badan dan BCS pada ternak diamati dengan metode korelasi rank Spearman. Koefisien korelasi pada domba antara umur dengan bobot badan sebesar 1.00 dan umur dengan BCS sebesar 1.00. Koefisien korelasi pada kambing antara umur dengan bobot badan sebesar 0.713 dan umur dengan BCS sebesar 0.743. Korelasi tersebut menunjukkan bahwa umur dengan bobot badan dan BCS pada ternak domba memiliki korelasi yang sangat kuat dan pada ternak kambing memiliki korelasi kuat., Body weight and Body Condition Score (BCS) are important indicators in the selection of Kurban animals. This research aim to analyze the correlation between age with body weight and body condition score in Kurban animals. The Kurban animals used were 10 beef cattles, 8 sheeps and 333 goats with measured and observed variables such as breed, age, body weight and body condition score (BCS). Correlation between age with body weight and BCS was observed by the Spearmann rank correlation method. The coefficient of correlation between age with body weight was 1.00 and with BCS was 1.00 in sheep. The correlation coefficient between age and body weight was 0.713, while with BCS was 0.743 in goat. The correlation shows that age with body weight and body condition score in sheep have a very strong correlation and strong correlation in goat.

Judul: Estimation Of Body Weight Kisar Sheep with Linear  Regression Analysis Approach to Body Size
Abstrak: Bobot badan merupakan salah satu tolak ukur dalam menentukan pakan, produksi daging, penentuan harga jual beli benih dan pemilihan generasi ternak. Penelitian ini bertujuan untuk mengkaji hubungan lingkar dada, panjang badan, tinggi pundak, lebar dada, dalam dada dengan bobot badan domba kisar menggunakan rumus analisis regresi. Sebanyak 90 ekor domba kisar yang terbagi dalam 45 ekor domba jantan dan 45 ekor domba betina yang dikelompokkan berdasarkan umur dan jenis kelamin digunakan untuk menentukan pendugaan bobot badan domba kisar berdasarkan ukuran linear tubuh. Analisis data yang digunakan dalam penelitian ini menganalisis hubungan antara ukuran tubuh dan berat badan domba, rumus yang digunakan adalah analisis regresi linear dengan persamaan y = a + (b ± Sb). Rumus pendugaan bobot badan domba kisar melalui variabel ukuran linear tubuh menunjukkan hasil yang paling akurat dengan nilai korelasi tertinggi ialah pada domba kisar betina umur I0 dan umur I2 ialah variabel lebar dada, sedangkan pada domba kisar betina umur I1 nilai korelasi tertinggi terjadi pada variabel panjang badan. Sedangkan domba kisar jantan umur I0 variabel lebar dada memiliki nilai korelasi tertinggi, pada umur I1 nilai korelasi tertinggi terjadi pada variabel tinggi pundak, dan pada umur I2 variabel tertinggi yaitu pada panjang badan. Rumus pendugaan bobot badan pada domba kisar jantan dan betina menunjukkan hasil yang berbeda nyata pada nilai intersep dan koefisien regresinya, sehingga perlu adanya pemisahan rumus. Sebaran data yang diperoleh pada hasil penelitian ini berbentuk linear., Bodyweight is one of the criteria used to determine feed, meat production, buying and selling prices, and livestock generation selection. Using the regression analysis formula, this study will look at the relationship between sheep's chest circumference, body length, shoulder height, chest breadth, chest depth, and body weight. To estimate the body weight of the Kisar sheeps based on morphometric size, a total of 90 kisar sheeps were used, divided into 45 male and 45 female sheep and grouped by age and sex. The data in this study was analyzed using age equalization, and then linear regression analysis with the equation y = a + (b Sb) x was used to determine the relationship between body size and bodyweight of sheep. The chest width variable had the highest correlation value in female Kisar sheep aged I0 and I2, while the body length variable had the best correlation value in Kisar sheep aged I1. While the male Kisar sheep's variable chest width had the highest correlation value at age I0, shoulder height had the highest correlation value at age I1, and body length had the highest correlation value at age I2.

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
