Judul: Analisis kelayakan usaha budidaya anggrek dalam menunjang tujuan program sentra anggrek Kota Tangerang Selatan
Abstrak: Pemerintah Kota Tangerang Selatan bekerjasama dengan Badan Pengkajian dan Penerapan Teknologi untuk menjadikan Kota Tangerang Selatan menjadi sentra anggrek. Pemerintah mencanangkan program sentra anggrek dengan salah satu tujuannya untuk menggerakkan perekonomian masyarakat. Tujuan dari skripsi ini adalah menganalisis kelayakan aspek non finansial, finansial, dan tingkat kepekaan usaha budidaya anggrek dalam menunjang tujuan program sentra anggrek Kota Tangerang Selatan. Untuk mencapai tujuan ini digunakan metode kelayakan aspek non finansial maupun finansial. Secara umum, budidaya anggrek dikatakan layak baik secara non finansial maupun finansial pada berbagai skala. Sedangkan, program sentra anggrek hanya layak dijalankan pada skala usaha besar karena memiliki NPV lebih dari present value UMK Kota Tangerang Selatan.

Judul: Analisis kelayakan usaha Anggrek pot Mita Permata Anggrek di Kelurahan Pasir Mulya Kota Bogor
Abstrak: Orchid pot is one of floriculture product that has the potential to be developed . The purpose of this study is to analyze the feasibility of orchid pots business Mitra Permata Anggrek, by analyzing the 3 varieties of varieties of Dendrobium, Vanda and Phalaenopsis. The analytical method used is the analysis is non-financial aspects such us the market, technical aspects, management and legal aspects, social aspects of economic, and environmental aspects. Financial analysis of investments is determined on several criteria such as NPV, IRR, Net B / C and Payback Period. Non-financial analysis is done with 4 scenarios, and the result is business orchid pots is proper to operation. Sensitivity analysis is performed to test the feasibility of the two conditions that the rising price of inputs (seeds) and reduction in the amount of production with calculate switching value. Results of test sensitivity for 4 scenarios show in conditions that the rising price of inputs (seeds), Orchid pot business use the 3 scenario its more sensitif. The results of test sensitivity reduction in the amount of production is Orchid pot business use the 3 scenario its more sensitif.

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.
