Judul: Analisis perilaku konsumen terhadap konsumsi susu bubuk dan susu kental manis di kota Bogor
Abstrak: Konsumsi suatu masyarakat Indonesia masih tergolong rendah jika dibandingkan dengan negara-negara berkembang lainnya di Asia. Rata-rata konsumsi susu di Indonesia hanya tercatat 8 Kg/thn, sedangkan Malaysia 51 Kg/thn, Filipina 22 kG/Thn dan Thailandc20 Kg/Thn. Data ini menunjukan bahwa konsumsi susu di Indonesia masih sangat tertinggal, terlebih bila dibandingkan dengan negara maju seperti Irlandia dan Swedia yang tingkat konsumsinya mencapai 163 Kg/Thn dan 157 Kg/Thn.

Judul: Analisis Pola Konsumsi susu bubuk, Susu Kental Manis, da Susu Cair Konsumen Rumah Tangga (Survey Pada Perumahan TaMan PAgelaran, Kelurahan Padasuka, Kecamatan Ciomas, bogor)
Abstrak: Susu merupakan salah satu bahan makanan asal hewan yang sangat penting bagi manusia karena kandungan gizinya yang tinggi. Hal itu menyebabkan susu banyak dipilih oleh rumah tangga guna memenuhi kebutuhan gizi bagi keluarga. Termasuk pada rumah tangga di Perumahan Taman Pagelaran. Warga Perumahan Taman Pagelaran mempunyai karakteristik yang beragam. Keragaman tersebut akan menyebabkan perbedaan tiap rumah tangga dalam memenuhi kebutuhan gizi bagi keluarganya. Hal tersebut juga akan menyebabkan terjadinya perbedaan permintaan susu, sehingga akan menyebabkan perbedaan pola konsumsi susu pada tiap rumah tangga tersebut. Tujuan dari penelitian ini adalah 1) mempelajari pola konsumsi susu bubuk, susu kental manis, dan susu cair pada konsumen rumah tangga di Perumahan Taman Pagelaran, dan 2) mempelajari faktor-faktor apa saja yang mempengaruhi pola konsumsi susu bubuk, susu kental manis dan susu cair pada konsumen rumah tangga di Perumahan Taman Pagelaran.

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.
