Judul: Analisis Densitas Energi Konsumsi dan Status Gizi serta Pengaruhnya terhadap Daya Ingat Sesaat
Abstrak: The aim of this study was to analyze the correlation between dietary energy density, nutritional status and influence towards Bogor elementary students’s short term memory. Design of this study is cross sectional study with purpossive sampling 111 elementary school students in Bogor. Children’s allowance, parents educational background and income, nutritional knowledge, food consumption, physical activity and short term memory were analyzed by chi square and logistic regression. The results showed that most of student consumed high energy density with average of dietary energy density was 2,13 kkal/g for girls and 1,98 kkal/g for boys. Children’s allowance and mother’s educational were variabels that had significant correlation with dietary energy density. Most of them had normal nutritional status but 27% of them were overweight and obese. Nutritional knowledge and breakfast habit were variabels that had significant correlation with nutritional status. Only nutritional knowledge and nutritional status that has significant influence towards their short term memory

Judul: Analisis Densitas asupan zat gizi dan hubungannya dengan status gizi siswa sekolah dasar di kota Bogor
Abstrak: AHMAD FAUZI. Analisis Densitas Asupan Zat Gizi dan Hubungannya dengan Status Gizi Siswa Sekolah Dasar di Kota Bogor. Dibimbing oleh IKEU TANZIHA. Penelitian ini bertujuan untuk menganalisis densitas zat gizi dan hubungannya dengan status gizi siswa sekolah dasar di Kota Bogor. Desain yang digunakan adalah cross sectional study dengan metode random sampling di empat sekolah dasar, kemudian dari masing-masing kelas diambil seluruh siswa sebagai contoh. Contoh berjumlah 123 siswa sekolah dasar. Jenis data yang dikumpulkan adalah data primer dan sekunder serta analisis statistik yang digunakan adalah uji korelasi chi square dan uji beda Mann Whitney. Hasil penelitian menunjukkan bahwa sebagian besar contoh memiliki densitas asupan protein (61%) dan zat besi (51%) yang cukup, sedangkan densitas asupan kalsium (61.8%), Vitamin A (95.9%) dan vitamin C (89.4%) tergolong kurang. Sebagian besar densitas pangan sarapan contoh termasuk kurang baik (78.8%). Jenis kelamin pada setiap kategori densitas asupan zat gizi tidak berbeda signifikan. Sebagian besar status gizi contoh normal tetapi 25% contoh mengalami kegemukan. Terdapat hubungan signifikan antara densitas asupan protein dengan status gizi., AHMAD FAUZI. The analysis of nutrient intake density and correlation with nutritional status at Elementary School Children in Bogor. Supervised by IKEU TANZIHA. The purpose of this study was to analyze nutrient intake density and correlation with nutritional status of elementary school student in Bogor. The design of this study was cross-sectional study by random sampling method in four elementary schools. The subject of this study were all students taken from each class, with the total number of subject were 123 students of elementary school. The data collected were primary and secondary data. The data were further anlyzed by Chi Square correlation and Mann Whitney test. The result showed that most of subject had adequate density nutrients score in proteins (61 %) and iron (51 %), while density nutrients score in calcium (61.8 %), vitamin A (95.9 %) and vitamin C (89.4 %) were less. Most of subject's nutrient density in breakfast were categorized poor (78.8 %). There is no significant difference in each category of nutrient intake density for different gender. Most of subject's nutritional status were normal, but 25% of them were obese. The density of proteins intake had significant correlations with nutritional status.

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.
