Abstrak: Students Papua referred to as of Leaving-Home students, who are want to continue their advance study to the university level that are outside the area of origin. The general objectives of this study were to assess nutrition knowledge, food consumption patterns, physical activity and their relationship to the nutritional status of students Papua in Bogor. This research was conducted in May-June 2013 followed a cross-sectional study design. Samples was purposively chosen with the total of 60 students who were fully participative in this study.The study showed that in general the nutritional knowledge of students belong to the category of less (65%); moderate (30%) and the rest (5%) as good. The average level of physical activity (PAL) based on the value of PAL between 1.40-1.69 which belongs to light activity. Most on the them (41.7%) were categorized as deficient energy, wereas most (35%) were categorized as deficient protein. Nutritional Status of students determined based on their BMI, its found that 15 % students are thin, 58.3% normal and 26.7 % student are categorized as obese. Statistical analysis by Rank Spearman correlation test showed that vitamin C consumption of the student in Baranangsiang significantly achieved recommended dietary allowance (p<0.05). Energy consumption significantly associated (p<0.05) with the nutritional status of the student in Dramaga. Sufficiency level of nutrients are still deficits, and need to be socialized to the students by using General Balanced Nutrition Guidelines (PUGS) in order to meet the daily nutritional needs of students.

Abstrak: This study aims to analyze the association between nutrition knowledge with food consumption pattern and physical activity of students in Bogor Agricultural University. Design of this study was cross sectional with purposive sampling 80 students in nutrition science and forest management Bogor Agricultural University. Nutrition knowledge related degenerative disease in sample GIZ (79.3±9.5) was higher than MNH (39.3±17.1). The average frequency of consumption dietary fats, sweetened food, salty and preserved food, fast food, soft drink and caffeinated beverages in sample MNH (8.8±5.2; 2.1±3.7; 16.5±11.2; 7.9±2.2; 4.6±3.7; 3.6±4.2; 2.6±3.0) times/week was higher than sample GIZ (7.8±4.0; 0.9±1.3; 13.5±8.7; 4.1±2.8; 2.3±3.3; 1.3±2.6) times/week, respectively. However, the average vi frequency of consumption vegetables and fruits in the sample GIZ (18.6±12.5; 10.3±8.9) times/week was higher than sample MNH (15.0±11.5; 6.1±5.4) times/week, respectively. Physical activity levels of sample GIZ (1.56±0.21) was relatively similar to the MNH (1.59±0.19). Based on Spearman correlation, there was a significant correlation (p<0.05) between nutrition knowledge related degenerative disease with frequency of consumption salty and preserved food, vegetables, fruits, and caffeinated beverages. There was no significant correlation (p≥0.05) between nutrition knowledge related degenerative disease with frequency consumption of dietary fats, sweetened food, fast food, soft drink, dan physical activity.

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
