Judul: Pengetahuan Gizi Atlet dan Pelatih, Asupan Gizi, dan Tingkat Kebugaran Atlet Sepak Bola Bhayangkara FC
Abstrak: Sepak bola merupakan salah satu olahraga yang populer di dunia. Tujuan penelitian ini adalah untuk menganalisis hubungan antara asupan gizi dan pengetahuan gizi atlet dengan tingkat kebugaran atlet sepak bola Bhayangkara FC. Desain penelitian ini adalah cross-sectional study dengan jumlah subjek yang dianalisis sebanyak 18 orang yang bersedia mengikuti penelitian dengan menandatangani informed consent dan tidak mengikuti seleksi atau latihan Tim Nasional. Hasil penelitian menunjukkan bahwa rata-rata tingkat kecukupan energi defisit ringan serta tingkat kecukupan protein dan lemak defisit berat. Rata-rata nilai VO2 max subjek sebesar 52.7 ± 2.45 ml/kg/menit. Terdapat hubungan yang signifikan antara asupan energi dengan tingkat kebugaran (p=0.032, r=0.506). Hasil uji menunjukkan tidak adanya hubungan signifikan antara asupan lemak, protein, karbohidrat, dan tingkat pengetahuan gizi atlet terhadap tingkat kebugaran atlet.

Judul: Hubungan Pengetahuan Gizi, Kecukupan Gizi, dan Status Gizi dengan Kebugaran Atlet Sepak Bola di PPOP DKI Jakarta
Abstrak: Prestasi tim sepak bola Indonesia semakin menurun saat ini. Kurangnya prestasi yang dicapai oleh suatu kesebelasan sepakbola dapat dipengaruhi oleh beberapa faktor, salah satunya kondisi fisik. Penelitian ini bertujuan menganalisis faktor-faktor yang berhubungan dengan kebugaran atlet. Studi cross sectional dilakukan pada atlet sepak bola di Pusat Pelatihan Olahraga Pelajar (PPOP) DKI Jakarta. Data primer dikumpulkan dari 22 atlet. Hasil penelitian menunjukkan sebagian besar atlet memiliki pengetahuan gizi sedang (54.5%), status gizi atlet normal (90.9%), tingkat kecukupan energi defisit berat (81.8%), persen kontibusi protein defisit berat (100%), persen kontribusi lemak defisit berat (31.8%), persen kontribusi karbohidrat defisit berat (86.4%), tingkat kecukupan kalsium defisit (100%), tingkat kecukupan zat besi normal (68.2%), tingkat kecukupn vitamin A normal (100%), tingkat kecukupan vitamin C defisit (100%), dan tingkat kebugaran cukup (63.64%). Hasil uji korelasi Spearman menunjukkan terdapat hubungan positif antara persen kontribusi lemak dengan tingkat kebugaran (p<0.05), dan hubungan negatif antara status gizi dengan tingkat kebugaran (p<0.05).

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.
