Judul: Optimizing Ornamental Fish Production at Bogorian Aquatics Farm, Bogor, West Java
Abstrak: Usaha budidaya ikan hias merupakan sektor industri perikanan yang berpotensi untuk lebih dikembangkan. Potensi ikan hias air tawar di Kabupaten Bogor sangat besar karena termasuk salah satu wilayah sentra produksi. Bogorian Aquatics Farm merupakan salah satu perusahaan budidaya ikan hias yang berpotensi untuk berkembang di Bogor. Perusahaan ingin mengetahui kombinasi produksi yang optimal, sehingga tujuan perusahaan dalam memaksimalkan keuntungan dapat tercapai. Penelitian ini bertujuan menganalisis optimalisasi produksi dan usaha ikan hias air tawar di Bogorian Aquatics Farm. Pengumpulan data dilakukan dengan observasi dan wawancara menggunakan metode studi kasus. Analisis data menggunakan linear programming serta perhitungan analisis usaha. Hasil menunjukkan bahwa penggunaan input produksi di perusahaan belum optimal karena masih terdapat nilai slack atau surplus pada faktor kendala serta diperoleh perbedaan antara kombinasi produksi aktual dan optimal. Perbandingan analisis usaha pada kondisi aktual dan optimal diperoleh keuntungan yang lebih tinggi pada kondisi optimal dengan peningkatan keuntungan dalam satu tahun produksi sebesar 18,08% dari kondisi aktual., Ornamental fish farming is a fisheries industry sector that has the potential to be more developed. The potential for freshwater ornamental fish in Bogor Regency is very large because it is one of the production center areas. Bogorian Aquatics Farm is one of the ornamental fish farming companies that has the potential to develop in Bogor. Companies want to know the optimal production combination, so that the company's goal of maximizing profits can be achieved. This study aims to analyze the optimization of production and freshwater ornamental fish business at Bogorian Aquatics Farm. Data collection was carried out by observation and interviews using the case study method. Data analysis used linear programming and business analysis calculations. The results showed that the use of production inputs in the company was not optimal because there was still a slack or surplus value in the constraint factor and a difference was obtained between the combination of actual and optimal production. Comparison of business analysis in actual and optimal conditions obtained higher profits in optimal conditions with an increase in profits in one year of production of 18,08% from actual conditions.

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.
