Judul: Pengamatan Lingkungan Kandang Berbasis Internet Of Things (Iot) PadaPertumbuhan Ayam Pedaging
Abstrak: Internet of Things (IoT) merupakan sistem jaringan dengan masing-masing tertanam sensor yang terhubung ke internet. Dengan menerapkan IoT dalam peternakan ayam, diharapkan kegiatan peternakan ayam akan lebih efektif. Ayam broiler merupakan ayam ras untuk menghasilkan daging dan merupakan peralihan vertebrata (berdarah panas) ke avertebrata (berdarah dingin) dengan suhu yang dibutuhkan pada saat pemeliharaan 23 – 24, The Internet of Things (IoT) is a network system with each embedded sensor connected to the internet. By implementing IoT in chicken farming, it is hoped that chicken farming activities will be more effective. Broiler chickens are a breed of chicken that produces meat and is a transition from vertebrates (warm-blooded) to invertebrates (cold-blooded) with the required temperature when rearing 23 – 24

Abstrak: Internet of Things (IoT) merupakan sistem jaringan dengan masing-masing tertanam sensor yang terhubung ke internet. Dengan menerapkan IoT dalam peternakan ayam, diharapkan kegiatan peternakan ayam akan lebih efektif. Ayam broiler merupakan ayam ras untuk menghasilkan daging dan merupakan peralihan vertebrata (berdarah panas) ke avertebrata (berdarah dingin) dengan suhu yang dibutuhkan pada saat pemeliharaan 23 – 24 ºC, sedangkan kelembaban yang ideal yaitu berkisar antara 50% – 70%. Suhu lingkungan Indonesia yang beriklim tropis mencapai rata-rata 27 °C – 28 °C, hal ini dapat mengakibatkan stres pada ayam. Ciri-ciri heat stress pada ayam yaitu terjadinya gangguan terhadap pertumbuhan, konsumsi pakan menurun, gelisah, sayap dikembangkan, konsumsi air meningkat, hingga berujung mati. Penelitian ini bersifat deskriptif dan menggunakan metode pengamatan dengan satu perlakuan lima ulangan. Parameter yang diukur dalam penelitian ini adalah suhu, kelembaban, pakan dan bobot ayam. Parameter tersebut untuk menghitung Temperature-Humidity Index (THI), Konsumsi Pakan, Pertambahan Bobot Badan dan Bobot Badan Akhir, Feed Conversion Ratio (FCR) , dan Indeks Performance (IP) menggunakan metode regresi dan korelasi. Analisis regresi pada penelitian ini diketahui memiliki pengaruh yang sangat signifikan antara variabel terikat (THI) terhadap variabel bebas (konsumsi pakan, FCR, PBB, dan IP) derngan nilai P < 0,01, dan variabel terikat (THI) terhadap variabel bebas (mortalitas) memiliki pengaruh yang signifikan dengan nilai P < 0,05. Sedangkan hasil ANOVA yang digunakan untuk mengetahui perbedaan antar kandang memperoleh superskrip yang sama.

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.
