Judul: Studi Kasus di Jakarta Timur
Abstrak: Makanan sangat besar pengaruhnya terhadap keadaan gizi seseorang khususnya pada usia bayi sampai balita karena kekurangan gizi pada masa ini dapat berpengaruh buruk terhadap pertumbuhan fisik dan mental tahapan selanjutnya. Kebutuhan akan makanan bayi siap saji khususnya bubur bayi semakin meningkat sejalan dengan perkembangan jumlah bayi dan balita dan peningkatan angkatan kerja wanita. Meningkatnya potensi pasar ini diikuti dengan meningkatnya kompetisi antar produsen produk makanan bayi yang terlihat dari munculnya berbagai merek dan jenis makanan bayi di pasaran.

Judul: Pengaruh pengetahuan gizi, konsumsi makanan ibu dan konsumsi makanan bayi terhadap status gizi bayi
Abstrak: Tujuan penelitian ini adalah mengetahui pengaruh pengetahuan gizi ibu terhadap konsumsi makanan ibu, pengaruh pengetahuan gizi ibu terhadap konsumsi makanan bayi, pengaruh konsumsi makanan ibu terhadap konsumsi ASI bayi dan pengaruh konsumsi makanan bayi terhadap status gizi bayi. Penelitian ini dilakukan di Kelurahan Pela Mampang, Kecamatan Mampang Prapatan, Jakarta Selatan. Penelitian berlangsung dari awal bulan Oktober sampai dengan akhir bulan Nopember 1988. Sampel adalah bayi yang berumur 0 12 bulan. Pengambilan sampel dilakukan secara "purposive" dengan kriteria bayi dalam keadaan sehat yaitu sebanyak 36 bayi yang menyusu ASI dan lima bayi (kasus) yang tidak menyusu ASI.

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.
