Judul: Hubungan Pola Konsumsi Pangan Sumber Lemak dan Kebiasaan Olahraga dengan Komposisi Lemak Tubuh dan Kebugaran pada Mahasiswi IPB
Abstrak: According to the World Health Organization ( WHO )it is predicted that 2020 around 60 % of deaths is caused by low physical fitness. The purpose of this study was to analyze the relationship pattern of food consumption and exercise habits with the composition of the IPB students body fat and fitness. The design of this study was cross sectional. Examples were 34 IPB students who were willing to be examples and in good health. Average nutritional status was normal, intake of energy, protein, fat, carbohydrate, and mineral examples like sports more than in the sample who do not like sports. Most of the examples of the type of exercise jogging exercise with a duration of 30 minutes per week . Body fat composition examples are not sports lower than the example that exercise. There is a significant relationship between the frequency of consumption of food sources of fat (p=0.000, r=0.628) and body fat composition. Similarly, there is a significant relationship between fat intake (p=0.001, r=0.530 ), exercise duration (p = 0.000 , r = 0.71 ) with fitness.

Abstrak: Economical progress in developing countries, including Indonesia, has generated many changes. There has been changes in lifestyle from active to less active as well as advances is technology. This resulted in changes in consumption which are generally use food instant. These changes can easily lead to degenerative diseases at a young age. The general objective of this study was to analyze the relationship between nutritional status and fitness levels of students with the specific objectives including 1) assess the characteristics, nutritional status and fitness level of samples; 2) analyze the relationship between the sample’s characteristics and BMI, body composition and fitness levels; 3) analyze the relationship between the adequacy level of energy - nutrient and BMI (Body Mass Index), body composition and fitness level; 4) analyze the relationship between BMI and fitness level; 5) analyze the relationship between body composition and BMI and fitness levels. The research was conducted using Cross Sectional study design with 75 students as samples. Primary data used included characteristics, nutritional status, body composition and fitness level of samples. The results showed that nutritional status of male students was not significantly different from the female students. In contrast, the percentage of body fat of men is lower than those in women. The level of fitness (flexibility and VO2max) was significantly higher in the men than of the women. BMI was significantly decreased with the level of fitness. Body fat percentage were significantly increased with BMI and body fat percentage were significantly decreased with the fitness level. The study suggested that students should improved the nutrients intake and do the exercise in order to have a good level of fitness.

Judul: Sintesis nanopartikel Cu2ZnSnS4 menggunakan teknik hidrotermal
Abstrak: Nanopartikel Cu2ZnSnS4 (CZTS) merupakan semikonduktor yang berpotensi sebagai fotokatalis untuk reaksi fotodegradasi zat pewarna. Semikonduktor ini memiliki sela pita yang jauh lebih kecil dibandingkan dengan semikonduktor TiO2, sehingga memungkinkan dapat berkerja hanya dengan paparan sinar matahari. Nanopartikel Cu2ZnSnS4 telah berhasil disintesis menggunakan teknik hidrotermal dengan suhu 200 oC selama 24 jam. Larutan Cu2ZnSnS4 dinetralkan menggunakan amonium hidroksida dan dialiri gas N2 sebelum proses hidrotermal. Hasil analisis mikroskop elektron pemayaran menunjukkan nanopartikel Cu2ZnSnS4 mengalami aglomerasi karena memiliki ukuran partikel yang besar. Hasil analisis difraktogram sinar-X menunjukkan bahwa Cu2ZnSnS4 yang dihasilkan memiliki struktur kesterit dengan senyawa fase sekunder yang terbentuk adalah CuS, ZnS, dan Cu2SnS3. Hasil uji fotodegradasi menunjukkan bahwa senyawa hasil sintesis memiliki kemampuan degradasi dibawah sinar matahari lebih baik dibandingkan dengan TiO2. Namun, pada paparan sinar UV, TiO2 mendegradasi biru metilena lebih baik daripada senyawa hasil sintesis. Kapasitas adsorbsi terhadap biru metilena sebesar 2.6780 mg/g menunjukkan bahwa senyawa hasil sintesis tidak mampu mengadsorpsi dengan baik, sehingga disimpulkan bahwa hilangnya biru metilena dari larutan disebabkan oleh fotodegradasi, bukan oleh adsorpsi
