Judul: Pengaruh Penambahan Daging Lumat Ikan Nila (Oreochromis Niloticus) Pada Simping Sebagai Makanan Camilan
Abstrak: Dewasa ini telah banyak bentuk olahan ikan ldmsusnya pada jenis makanan camilan yang umumnya disukai oleh semua kalangan. Diversifikasi bentuk olahan ikan adalah upaya untuk menyediakan kebutuhan masyarakat terhadap gizi dan upaya untuk menggalakan makan ikan untuk keluarga sehat, kuat dan cerdas. Pemanfaatan daging lumat ikan nila (Oreochromis niloticus) sebagai bahan suplementasi pada simping merupakan salah satu alternatif untuk menghasilkan produk pangan dengan nilai gizi tinggi. Tujuan dari penelitian ini adalah untuk mempelajari cara pembuatan simping dan simping ikan nila, mempelajari kandungan gizi simping ikan nila, mendapatkan formula yang tepat untuk pembuatan simping ikan nila dan mengetahui pengaruh daging lumat ikan nila pada simping. Penelitian ini dilaksanakan pada bulan April sampai dengan bulan Juni 2002. Penelitian dilakukan di CV Ibu Entin, Desa Sawah Kulon, Kecamatan Pasawahan, Kabupaten Purwakarta, Jawa Barat. Pengujian mutu simping dilaksanakan di Laboratorium PAU-IPB, Laboratorium fisika dan kimia hasil perikanan dan Laboratorium industri hasil perikanan.

Judul: Pengaruh Penambahan Daging Lumat Ikan Nilem (Csteochilus hasselti) pada Pembuatan Simping sebagai Makanan Camilan
Abstrak: Simping adalah salah satu bentuk produk makanan tradisional daerah Purwakarta (Jawa Barat) dengan bahan baku utama tepung tapioka dan terigu. Untuk meningkatkan variasi rasa dan nilai gizi pada produk simping maka dilakukan penambahan daging lumatan. Daging lumatan yang dipakai adalah dari ikan nilem (Osteochilus hasselti) yang merupakan salah satu ikan budidaya. Penggunaan ikan budidaya dimaksudkan dalam ha1 penyediaan ikan, lebih mudah diperoleh dibanding dengan ikan laut, yang penyediaanya tidak tergantung pada musim di daerah penangkapan.

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.
