Judul: Hubungan Pola Konsumsi Pangan Sumber Protein serta Aktivitas Fisik dengan Massa Otot pada Remaja di Perdesaan dan Perkotaan.
Abstrak: Penelitian ini bertujuan menganalisis hubungan pola konsumsi pangan sumber protein, aktivitas fisik dan massa otot pada remaja di perdesaan dan perkotaan. Desain yang digunakan adalah cross sectional study. Subjek dalam penelitian ini berjumlah 152 remaja usia 12-15 tahun. Penelitian menggunakan data sekunder yaitu sebagian data penelitian “Gaya Hidup dan Aspek Gizi pada Remaja di Perdesaan dan Perkotaan” (Dwiriani et al. 2013). Usia contoh di perdesaan lebih tua, sementara uang saku dan pendidikan orang tua contoh lebih tinggi di perkotaan dibandingkan perdesaan. Frekuensi konsumsi daging sapi, ikan pindang, dan susu lebih tinggi di perkotaan, tetapi contoh di perdesaan mempunyai tingkat aktivitas fisik dan massa otot lebih tinggi dibandingkan perkotaan. Contoh yang mempunyai status gizi gemuk dan obesitas lebih banyak di perkotaan dibandingkan perdesaan. Tidak terdapat hubungan antara pola konsumsi pangan sumber protein, aktivitas fisik dan massa otot, tetapi hanya status gizi yang mempunyai hubungan signifikan dengan massa otot.

Judul: Hubungan Pola Konsumsi Pangan dan Aktivitas Fisik Anak Sekolah dengan Status Gizi Lebih di Daerah Perkotaan dan Perdesaan Bogor
Abstrak: The prevalence of obesity continues to increase, including in childhood, not only in urban areas (10.4%) but also in rural areas (8.1%). The purpose of this research was to analyze the relationship between the pattern of food consumption and physical activity of elementary school children with overweight and obese status in urban and rural areas of Bogor. The research was conducted by applying a cross sectional study design. Subjects consist of 60 elementary school children of 4th and 5th graders in SDN Polisi 5 and SDN Babakan Dramaga 4, that had overweight and obese status, and in good health. Data was collected include child and family characteristics, patterns of consumption and physical activity. The average z-score (BMI/A), energy intake, protein intake and fat intake was higher in urban areas than in rural areas, whereas intake of carbohydrates was lower in urban than rural. The majority of physical activity in urban areas and rural were in the mild category. Family income, age of parents and children allowance of urban area were higher significantly (p<0.05) than rural area. There were a significant correlation between maternal nutritional status (p=0.040, r=0.266), energy intake (p=0.000, r=0.505), protein intake (p=0.003, r=0.381), and fat intake (p=0.001, r=0.426) with overweight and obese status of children.

Judul: Isolasi dan pemurnian bahan aktif dari mikroalga BTM 11 sebagai inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus is the cause of hepatitis C disease which has high virulence. Recent therapy using combination of ribavirin and alpha interferon has short efficiency < 80%. Thus, the discovery of new drug is needed. Antiviral drugs can be discovered through molecular target therapy by finding the inhibitor of RNA helicase that play role in viral replication. Inhibitor can be derived from chemical compound produced by microalgae. The aim of this research was to isolate the active compound from microalgae BTM 11 which had inhibitory activity against RNA helicase. Inhibitory activity was measured by releasing of phospate inorganic in colorimetric ATPase assay. Crude extract was fractionated using gel filtration chromatography with methanol in chloroform solvent. The result showed that Fraction 3 has the highest inhibitory activity which (81.205%). Phytochemical test of crude extract indicated positive flavonoids and coumarin. Thin layer chromatography (TLC) analysis with eluent chloroform: methanol gave 2 spots with Rf value of 0.8 and 0.37. Moreover, high performance liquid chromatography (HPLC) analysis showed absorption peak with the highest abundance at the retention time of 12.483 minute and 16.617 minute was 266 nm and 230 nm. According to these of phytochemical, TLC, and HPLC, inhibitor compound from BTM 11 belongs to flavonoids.
