Abstrak: This study was aimed to analyze the correlation between food preferences and energy protein intake with physical endurance in Indonesian Military Student Center. Cross sectional design was applied in this study at Pusdikzi and Pusdikintel Strat Kodiklat TNI. Total subject were 107 students. The result showed that food preferences between two kinds student had no difference. The recommended daily allowances, intake also level adequacy of energy and protein on Pusdikzi was higher with Pusdikintel Strat significanly (p<0.05). The physical endurance of two kinds showed Pusdikzi was higher significanly between Pusdikintel Strat. Spearman test correlation result showed there was an association between age (p<0.051, r=0.245) and nutritional status (p>0.05, r=0.017) with food preferences. There no association between food preferences with energy (p>0.05, r=0.021) and protein level intake (p>0.05, r=-0.048). There was an association between energy (p<0.05, r=0.395) and protein adequacy level (p<0.05, r=0.588) with physical endurance.

Abstrak: The purposes of this study were to analyze the correlation of energy and protein intake with physical endurance, water consumption with physical endurance and supplements with physical endurance. Cross sectional design was applied in this study at Education Center of Engineers (Pusdikzi) and the Education Center for Strategic Intelligence (Pusdikintel Strat) Kodiklat TNI. Total sample are 107 male students. Drinks frequencies in both Pusdikzi (62.2%) and Pusdikintel (72.2%) were > 8 glass/day, prefered drinking time was after wake up in Pusdikzi (58.5%) and in Pusdikintel Strat (53.7%), plain water in Pusdikzi was bottled plain water (55.6%) because it is safe and healthy (57.4%). Subject in Pusdikintel Strat prefered non-bottled plain water (68.9%) because safe and healthy (54.7%). Pearson correlation test result showed that there was significant correlation between energy (p<0.05, r=0.395 ) and protein level intake (p<0.05, r=0.588) with physical endurance (VO2max). There was also significant correlation between water sufficient level with physical endurance (VO2max) (p<0.05). Rank Spearman correlation test result showed that there was significant correlation between supplement consumption and physical endurance (VO2max) (p<0.05.)

Judul: Sintesis Krisin dari Floroglusinol
Abstrak: Flavone is a class of flavonoid, widely distributed in vascular plants. Flavones containing hydroxyl groups at 5 and 7 position are quite important regarding their biological activities and their abiquity in nature. Flavone having hydroxyl groups only at position 5 and 7 or 5,7-dihydroxyflavone is known as chrysin. In this study, crude chrysin had been successfully synthesized in 3 steps from phloroglucinol as starting material. Phloroglucinol was acetylated with acetonitrile and HCl gas, resulting phloroacetophenone amount to 74%. Phloroacetophenone benzoylation with 4.5 equivalents of benzoyl chloride produced tribenzoyl phloroacetophenone in 103–107% of yield and the subsequent Baker-Venkataraman rearrangement of the ester by using KOH in dried pyridine produced crude chrysin, with conversion percentage of 71.62%. All synthetic products had been characterized by melting point and spectroscopically.
