Judul: Pengaruh Tata Letak Sisiran Baru terhadap Pertambahan Luas Permukaan Sarang Koloni Lebah Madu (Apis ceranp)
Abstrak: Lebah madu adalah serangga sosial yang bertempat tinggal di dalam sarang yang terdiri dari sisiran-sisiran yang dibentuk menggantung vertikal ke bawah. Sarang tersebut berfungsi sebagai tempat penyimpanan makanan (madu dan tepungsari) dan pemeliharaan tetasan (telur, larva dan pupa). Sarang lebah pentjng bagi kehidupan lebah madu, oleh sebab itu perlu diperhatikan teknik untuk mempercepat pembentukkannya.

Judul: Pengaruh Pemberian Ransum Makanan Buatan terhadap Pertumbuhan dan Perkembangan Koloni Lebah Madu Apis mellifera Linn
Abstrak: Lebah madu merupakan salah satu serangga yang banyak hidup di hutan dan menghasilkan hasil hutan non kayu yang berupa antara lain madu dan lilin lebah. Salah satu syarat untuk pengembangan budidaya lebah madu adalah tersedianya sumber pakan lebah (*bee forage*) yang cukup dan berkesinambungan. Dalam hal ini pengembangan koloni lebah madu memerlukan ketersediaan serbuk sari bunga/polen dan nektar yang memadai dari beraneka ragam bunga jenis tanaman pakan lebah.

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.
