Judul: Asupan Energi-Protein dan Kebiasaan Olahraga Kaitannya dengan Massa Otot dan Daya Tahan Kardiorespirasi pada Mahasiswa Kelompok UKM dan Non-UKM Sepakbola IPB
Abstrak: Exercise habit is useful for health of the present and future, namely to maintain ideal body weight, to increase bone mineral density and to improve cardiorespiratory endurance. The objective of this study was analyze the relationship between energy-protein intake and exercise habit to muscle mass and cardiorespiratory endurance. The study design was cross sectional. Nutritional status subjects was normal in average. Intakes of energy, protein, fat, carbohydrate, and mineral subject in UKM group was higher than intakes in non-UKM group. Exercise habit in UKM group was more frequent than that in non-UKM group. Cardiorespiratory endurance in UKM group better than non-UKM group. There was a significant relationship between intake of energy (p=0.003, r=0.415) and protein (p=0.009, r=0.365) with cardiorespiratory endurance. Similiarly, there was a significant relationship between exercise frequency (p=0.004 r=0.395) and exercise duration (p=0.010, r=0.361) with cardiorespiratory endurance

Abstrak: The objective of this study was to analyze the association of nutritional knowledge, food diversification, exercise habits and fitness in soccer club members in Bogor Agricultural University. A cross sectional study of 25 subjects was conducted. The study showed the average score of subjects’ nutritional knowledge was categorized as moderate (80%) and food consumption of most of the subjects (84%) were not varying. Energy and fat sufficiency levels of the subjects were in normal category. Protein, carbohydrate and vitamin A sufficiency levels of most of the subjects were in below normal category. Calcium Iron, and vitamin C sufficiency levels of subjects were sufficient. Most of the VO2max of 64% subjects were in sufficient category. The study showed that there was correlation (p<0.05) between nutritional knowledge and exercise habits, nutritional knowledge and fitness, exercise habits and fitness. There was no correlation (p>0.05) between nutritional knowledge and food diversification and nutrient sufficiency level.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
