Judul: Pengetahuan Gizi, Sikap, dan Konsumsi Fast Food serta Serat pada Mahasiswa Non Gizi IPB
Abstrak: Pengetahuan gizi dan sikap merupakan hal yang umumnya berkaitan dengan perilaku atau kebiasaan seseorang dalam mengonsumsi makanan. Transisi tempat tinggal memungkinkan bagi mahasiswa untuk mengalami perubahan kebiasaan makan. Penelitian ini bertujuan menganalisis pengetahuan gizi, persepsi, dan konsumsi fast food serta serat pada mahasiswa. Penelitian ini melibatkan 64 subjek yang dibagi ke dalam 2 kelompok yaitu kelompok contoh yang tinggal dengan orang tua dan contoh yang tidak tinggal bersama orang tua. Data karakteristik contoh, karakteristik keluarga, pengetahuan gizi, dan persepsi terhadap konsumsi fast food diperoleh dengan menggunakan instrumen kuesioner, frekuensi konsumsi fast food diperoleh menggunakan Food Frequency Questionnaire (FFQ), sedangkan data asupan serat diperoleh melalui recall 1 x 24 jam pada hari libur dan kuliah. Tidak terdapat perbedaan yang nyata (p>0.05) antarkelompok contoh pada variabel pengetahuan gizi, sikap, dan asupan serat. Terdapat perbedaan nyata (p=0.012) antara kedua kelompok contoh pada frekuensi konsumsi fast food tradisional. Terdapat hubungan yang signifikan dan negatif (p=0.019 r=-0.294) antara pengetahuan gizi dengan frekuensi konsumsi fast food secara keseluruhan. Hasil uji korelasi Spearman menunjukkan tidak ada hubungan yang signifikan antara konsumsi fast food dan asupan serat dengan status gizi contoh.

Judul: Hubungan Pengetahuan dan Sikap Gizi serta Konsumsi Fast Food dan Asupan Serat dengan Status Gizi Siswa SMA Kornita IPB
Abstrak: ABSTRAK MIFTAH NUR HASANAH. Hubungan Pengetahuan dan Sikap Gizi serta Konsumsi Fast Food dan Asupan Serat dengan Status Gizi Siswa SMA Kornita IPB. Dibimbing oleh IKEU TANZIHA. Era globalisasi memberikan dampak yang sangat besar dalam perkembangan di segala aspek kehidupan dan mengakibatkan perubahan gaya hidup dan kebiasaan makan masyarakat yang cenderung kurang sehat. Kebiasaan makan seseorang dipengaruhi oleh pengetahuan gizi dan sikap. Penelitian ini bertujuan menganalisis hubungan pengetahuan gizi, sikap dan konsumsi fast food, serta asupan serat dengan status gizi siswa SMA Kornita IPB. Desain penelitian ini adalah cross sectional study yang melibatkan 62 subjek yang dipilih dengan metode insidental sampling. Pengumpulan data dilakukan dengan instrument kuesioner google form, wawancara via telepon, dan pengukuran antropometri dilakukan secara langsung. Hasil penelitian menunjukkan bahwa 71,1% subjek memiliki pengetahuan gizi baik dan 72,6% subjek memiliki sikap netral terhadap konsumsi fast food. Tidak terdapat hubungan yang signifikan antara variabel pengetahuan gizi dengan frekuensi konsumsi fast food secara keseluruhan, tradisional, maupun modern. Hasil analisis uji korelasi terdapat hubungan yang tidak signifikan (p>0,05) antara sikap terhadap fast food dengan frekuensi konsumsi fast food secara keseluruhan, tradisional, maupun modern. Terdapat hubungan yang signifikan positif antara konsumsi fast food secara keseluruhan (p=0,050 r=0,250) dan modern (p=0,025 r=0,285) dengan status gizi. Tidak terdapat hubungan yang signifikan antara asupan serat dengan status gizi (p=0,354 r=-0,0120).

Correlation Between Nutritional Knowledge and Perception, Fast Food Consumption and Dietary Fiber Intake with Nutritional Status of SHS Kornita IPB Students. Supervised by IKEU TANZIHA Globalization has caused a rapid growth of all aspect of life and change the lifestyles and eating habits that tend to be unhealthy. Eating habits are influence by nutritional knowledge and attitude. The aim of this study is to analyze the correlation between nutritional knowledge, perception of fast food, fast food consumption, and dietary fiber intake with nutritional status of SMA Kornita IPB students. The design of this research is a cross sectional study with 62 subjects selected by purposive sampling. Data was collected using online questionnaire with google form, interview by phone, and anthropometric measurement. Most of subjects (71.1%) and most of subjects has neutral perception of fast food (72.5%). There was no significant correlation (p>0.05) between nutritional knowledge with frequency of fast food consumption for traditional, modern, and overall. There was no significant correlation (p>0.05) between perception of fast food with frequency of fast food consumption for traditional, modern, and overall. There was significant and positive correlation between frequency of modern and overall fast food consumption with nutritional status (p=0.050 r=0.250) and modern (p=0.025 r=0.285). There was no significant correlation between dietary fiber intake with nutritional status (p=0.354 r=-0.0120).

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
