Judul: Tingkat Pendapatan Dan konsumsi Giz Keluarga Petani Kecil : Studi kasus Di desa Mekarsari, Kecamatan Cikajang Kabupaten Garut Propinsi Jawa barat
Abstrak: Tujuan Umum penelitian ini adalah untuk mengetahui pengaruh pelaksanaan Proyek Pembinaan Peningkatan Pendapatan Petani Kecil (P4K) terhadap tingkat hidup keluarga petani kecil, sedangkan tujuan khusus adalah melihat perbedaan pendapatan, alokasi pengeluaran, tingkat kecukupan konsumsi energi, protein, vitamin A dan zat besi keluarga petani kecil peserta dengan bukan peserta Proyek P4K. Penilaian pengaruh pelaksanaan Proyek P4K terhadap tingkat hidup keluarga petani kecil dilakukan dengan membandingkan dua golongan responden, yaitu keluarga petani kecil peserta dan bukan peserta Proyek P4K. Tingkat hidup petani kecil digambarkan sebagai besarnya pendapatan, pengeluaran pangan dan non pangan, tingkat kecukupan konsumsi energi, protein, vitamin A dan zat besi keluarga. Untuk melihat perbedaan tersebut digunakan uji beda T-Student.

Judul: Mempelajari upah buruh tani dan hubungan pendapatan dengan konsumsi energi-protein pada keluarga petani kecil : studi kasus di Desa Karangsari, Kecamatan Karanganyar, Kabupaten Pekalongan
Abstrak: Penelitian ini bertujuan untuk mempelajari upah buruh tani, pengeluaran pangan dan non pangan, tingkat konsumsi energi dan protein dan hubungan pendapatan dengan konsumsi energi dan protein pada keluarga petani kecil. Penelitian menggunakan data sekunder, yang merupakan sebagian data dari penelitian Faktor Gizi sebagai determinan Produktivitas Kerja Buruh Tani di Daerah Pertanian Supra Insus. Data yang digunakan adalah 1) identitas keluarga, 2) konsumsi pangan, dan 3) pendapatan keluarga. Analisis data dilakukan secara deskriptif dan analisa statistik. Data pendapatan merupakan data pendapatan dari berburuh tani dan sumber lain. Besar upah dibandingkan dengan upah berwawasan gizi dan Kebutuhan Fisik Minimum. Konsumsi dievaluasi dengan kecukupan menurut WKNPG (1993) berdasarkan Unit Konsumen Energi dan Unit Konsumen Protein. Analisis Regresi digunakan untuk melihat bentuk hubungan antara pendapatan dan konsumsi energi dan protein.

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.
