Judul: Faktor-faktor yang Mempengaruhi Perilaku Konsumsi Pangan Organik pada Kelompok Vegetarian di Kota Bogor
Abstrak: Trend of healthy lifestyle is increasing in modern society. Healthy lifestyle becomes one of quality standards. One of the efforts to live a healthy lifestyle has been practised in Indonesia, including by introduce organic foods. Studies about organic food consumption in Indonesia are still limited. The purpose of this study was to determine the factors associated with behavior of organic foods consumption among vegetarian in Bogor City. The method used in this study was cross sectional design with 42 vegetarians as study participants. The study was conducted in August until September 2014. Data were collected using questionnaire and Food Frequency Questionnaire (FFQ). The data analysis was performed using univariate analysis for frequency distributions, bivariate analysis for Chi Square test, and double logistic regression test with prediction model. The study results shout that factors related to organic food consumption behavior in vegetarian were age, gender, education, income, and knowledge (Pvalue < 0.05 ). Further more, the variables that were not associated in this study were the number of family member, job, and illness history. The most dominant factor was the income.

Judul: Pola Konsumsi dan Status Gizi pada Kelompok Vegetarian di Kota Bogor
Abstrak: The objective of this study was to analyze consumption patterns and nutritional status of vegetarian groups in Bogor. The study used cross sectional design and study participants were recruited purposively. The number of subjects was 42 vegetarian consisted of 22 men and 20 women. The result showed that nutritional adequacy level of energy of the vegetarian groups experienced deficiency of men (50%) and women (60%). Nutritional adequacy level of protein of the vegetarian groups of men experienced deficient (59%) and women (65%). Nutritional adequacy level of fat of the vegetarian groups experienced a shortage of men (52%) and women (48%). Nutritional adequacy level of carbohydrates of the vegetarian groups were good of men (64%) while women were deficient (75%). Nutritional adequacy level of vitamins and minerals of the vegetarian groups experienced a shortage of men (100%) and women (100%). The Spearman statistical analysis showed that there was no correlation (p>0.05) between type of vegetarian (vegan, lacto vegetarian vegetarian dan lacto-ovo vegetarian vegetarian) and old vegetarian with the level of recommended dietary allowance.

Judul: Formulasi Hamilton Untuk Menggambarkan Deformasi Gelombang Soliter Dengan Dasar Tidak Rata Pada Fluida Dua Lapisan
Abstrak: Gelombang internal adalah suatu gelombang yang muncul di bawah permukaan laut sehingga gelombang ini tidak teramati secara kasat mata. Formulasi Hamilton dirumuskan untuk menjelaskan gerak gelombang ini. Dalam hal ini diasumsikan bahwa fluida yang ditinjau terdiri atas dua lapisan dengan masing-masing lapisan memiliki rapat massa yang konstan. Selain itu, diasumsikan pula fluida yang ditinjau berupa fluida tak mampat (incompressible) dan tak kental (invicid). Formulasi Hamilton dilakukan dengan meninjau fluida dua lapisan yang berada pada domain yang dibatasi oleh batas atas yang rata dan batas bawah yang tidak rata. Hamilton (energi total)-nya didefinisikan sebagai penjumlahan antara energi kinetik dan energi potensialnya. Karena energi kinetik tidak secara eksplisit dinyatakan dalam peubah fisis, maka digunakan metode asimtotik untuk menentukan energi totalnya. Dalam hal ini diasumsikan bahwa gelombang interfacial yang ditinjau cukup panjang, dan amplitudo yang cukup kecil. Persamaan Korteweg de- Vries (KdV) diperoleh, jika disumsikan bahwa gelombang interfacial hanya merambat pada satu arah, sedangkan jika gelombang tersebut merambat ke dua arah, diperoleh persamaan Boussinesq.
