Judul: Pengaruh pemberian biskuit tinggi protein dari tepung Ikan Lele Dumbo (Clarias gariepinus) terhadap status gizi anak balita gizi kurang di Kabupaten Sukabumi
Abstrak: Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian ikan lele berprotein tinggi (Clarias gariepinus) pemberian biskuit terhadap status gizi balita anak-anak. Pra-eksperimental dengan desain one group pretest-posttest diterapkan pelajaran ini. Penelitian dilaksanakan pada bulan Maret sampai Juni 2011, di Simpenan dan Kecamatan Pelabuhanratu Kabupaten Sukabumi. Kriteria inklusi bersifat purposif pengambilan sampel adalah anak-anak dengan berat badan kurang (-3,0≤ Z score<-2,0) yang dikarakterisasi tanpa penambahan berat badan selama tiga kali penimbangan bulanan eksekutif, dan sukarela mengikuti observasi selama 88 hari. Sebanyak 42 balita berpartisipasi penuh dalam penelitian ini. Data primer (karakteristik sosial ekonomi balita dan keluarganya, kondisi lingkungan, konsumsi makanan, pola makan dan kesehatan orang tua, konsumsi biskuit selama 88 hari dan angka kesakitan) dan data sekunder (deskripsi wilayah Sukabumi dan daftar nama anak balita) adalah dikumpulkan seluruhnya. Analisis statistik menggunakan uji Spearman dan uji t sampel berpasangan untuk menganalisis hubungan dan perbedaan rata-rata variabel data. Hasil penelitian menunjukkan ada hubungan yang signifikan antara status gizi balita dengan tingkat kepatuhan (r = 0,718, p<0,05), kecukupan energi tingkat (r = 0,741, p<0,05) dan tingkat kecukupan protein (r = 0,775, p<0,05). Pemberian biskuit ikan lele (Clarias gariepinus) berprotein tinggi meningkatkan status gizi balita secara signifikan (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.
