Judul: Analisis Hubungan antara Kecukupan Gizi dan Status Gizi dengan Tingkat Kebugaran Mahasiswa IPB
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: Pengetahuan Gizi, Kebiasaan Makan, Konsumsi Minuman Manis, Tingkat Kecukupan Gizi, dan Status Gizi Mahasiswa IPB University.
Abstrak: Penelitian ini bertujuan untuk menganalisis pengetahuan gizi, kebiasaan makan, konsumsi minuman manis, dan tingkat kecukupan energi dan zat gizi dengan status gizi pada mahasiswa IPB University. Desain penelitian ini adalah cross sectional study dengan melibatkan 46 mahasiswa berstatus gizi normal dan 46 mahasiswa berstatus gizi gemuk/obesitas. Sebagian subjek memperoleh tingkat pengetahuan gizi rendah (50%), skor kebiasaan makan rendah (81,5%), asupan energi minuman manis sedang (45,7%), frekuensi konsumsi minuman manis sering (75%), dan tingkat kecukupan energi (76,1%), protein (68,5%), lemak (67,4%), dan karbohidrat (78,3%) kurang. Terdapat perbedaan yang signifikan antara kelompok status gizi normal dan gemuk pada variabel asupan energi minuman manis dan frekuensi konsumsi minuman manis (p<0,05). Uji korelasi menunjukkan terdapat hubungan yang signifikan antara frekuensi konsumsi minuman manis, tingkat kecukupan protein dan lemak dengan status gizi (p<0,05). Hasil uji regresi menunjukkan secara keseluruhan terdapat pengaruh antara frekuensi konsumsi minuman manis terhadap status gizi., This study aims to analyze the nutritional knowledge, eating habits, consumption of sweetened beverages, energy and nutrients adequacy level with the nutritional status of IPB University students. The design of this study was cross sectional study involved 46 students with normal nutritional status and 46 students with overweight/obese nutritional status. Most subject has low nutritional knowledge (50%), low eating habits’ score (81,5%), moderate energy intake of sweetened beverages (45,7%), high frequency of sweetened beverages consumption (75%), and low adequacy level of energy (76,1%), protein (68,5%), fat (67,4%) dan carbohydrate (78,3%). There was a significant difference of normal and overweight/obese students in energy intake of sweetened beverages and frequency of sweetened beverages consumption (p<0,05). There was a significant correlation between frequency of sweet beverages consumption, adequacy level of protein and fat with nutritional status (p<0,05). Regression test result showed over all there was an effect in frequency of sweetened beverages consumption to nutritional status.

Judul: Sintesis Nanorod Seng Oksida (ZnO) dengan Metode Sonokimia
Abstrak: Gelombang ultrasonik telah digunakan untuk membantu sintesis ZnO. ZnO terbentuk dari campuran ZnAc dan NaOH. ZnO disintesis dengan variasi konsentrasi ZnAc 0.5 M ( ZnO 1:1 ) dan 1.5 M ( ZnO 3:1 ) yang dicampurkan dengan NaOH konsentrasi 0.5 M. Sampel yang diporoleh dikarakterisasi dengan XRD dan SEM. Karakterisasi difraksi sinar-X menunjukkan bahwa struktur kristal ZnO yang dihasilkan merupakan heksagonal dengan pertumbuhan yang dominan pada orientasi bidang nonpolar a dengan indeks hkl 101. Kristalinitas dan kemurnian kristal ZnO 1:1 lebih baik dibandingkan ZnO 3:1 ditunjukan dengan intensitas puncak difraksi sinar-X yang lebih tinggi, sempit dan tajam. Untuk ukuran kristalit ZnO 1:1 mempunyai rata-rata ukuran kristalit 30.57 ± 4.31 nm sedangkan ZnO 3:1 mempunyai ukuran rata-rata 20.25 ± 7.12 nm. Dari ukuran kristal yang terbentuk partikel ZnO termasuk nanokristal. ZnO 1:1 terbentuk batang-batang nano (nanorods) sedangkan pada ZnO 3:1 tidak terbentuk batang-batang nano (nanorods). Untuk ukuran morfologi, ZnO 1:1 mempunyai rata-rata ukuran butiran kristal 230 nm dan lebih besar dibandingkan ukuran ZnO 3:1 yang mempunyai rata-rata ukuran butiran kristal 50 nm.
