Judul: Kajian Fonnulasi, Kelayakan, dan Pengukuran Nilai Tambah Usaha Kecil Kerupuk Singkong (Manihot utilissima Pohl) dengan Penambahan Daging Lele Dumbo (Clarias gariepinus)
Abstrak: Kerupuk merupakan salah satu jenis makanan ringan yang telah lama dikenal sebagai makanan tambahan untuk lauk-pauk atau sebagai makanan kecil (snack food). Berbagai jenis kerupuk banyak dijumpai di pasaran, baik dalam bentuk mentah maupun yang telah digoreng. Pembuatan kerupuk dapat dilakukan sccara sederhana dan tidak harus menggunakan teknologi proses yang rumit, sehingga dapat diterapkan dalam usaha skala kecil atau skala rumah tangga. Scbagai komoditi perdagangan, kcrupuk termasuk ke dalam jenis produk industri yang mempunyai potensi cukup baik dengan pemasaran yang tersebar di dalam dan luar ncgcri.

Judul: Analisis kelayakan usaha penggorengan kerupuk (studi kasus usaha kecil sumber makmur sentosa di Darmaga, Kabupaten Bogor)
Abstrak: Kinerja Usaha Kecil Menengah (UKM) dalam beberapa tahun terakhir terus meningkat. Besaran Produk Domestik Bruto yang diciptakan UKM tahun 2003 mencapai nilai Rp. 1.0135 triliun (56.7 persen dari total PDB Nasional) dengan perincian 41.1 persen berasal dari Usaha Kecil dan 15.6 persen dari Usaha Menengah. Pertumbuhan ekonomi pada usaha menengah lebih tinggi dibandingkan dengan pertumbuhan ekonomi pada usaha kecil. Namun demikian pertumbuhan yang tinggi tidak menjadikan usaha menengah sebagai kelompok yang memeberikan sumbangan paling tinggi dalam pertumbuhan ekonomi nasional. Sebaliknya walaupun pertumbuhan kelompok usaha kecil tidak secepat usaha menengah namun peranannya cukup besar dalam penciptaan nilai tambah nasional. Industri pengolahan kerupuk merupakan salah satu diantara beragam jenis UKM dalam bidang pengolahan makanan dan minuman yang ada. Kerupuk merupakan salah ssatu jenis makanan ringan yang sangat digemari oleh masyarakat luas dari berbagai macam golongan ekonomi.

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.
