Judul: Perancangan Sistem Informasi Usaha Perikanan Budidaya Udang Galah di Provinsi Bali Berbasis Internet
Abstrak: Produksi udang galah (Macrobrachium rosenbergii) yang tems meningkat, potensi pasar yang besar serta dukungan dad Pemerintah Daerah Bali mempakan modal besar bagi pengembangan usaha perikanan budidaya udang galah di Provinsi Bali. Pengembangan us aha budidaya udang galah di daerah Bali melibatkan berbagai pihak yang terkait seperti produsen udang galah, industri pakan, balai benih, lembaga pemasaran, lembaga keuangan, investor, dan pemerintah. Aliran informasi yang kompleks jelas memerlukan adanya teknik pengelolaan informasi yang baik, sehingga mampu memenuhi kebutuhan informasi dari banyak pihak terkait dalam kegiatan usaha perikanan budidaya udang galah di Provinsi Bali. Untrrk dapat memenuhi kebutuhan tersebut maka sistem informasi yang berbasis jaringan luas (Internet) perlu dikel1lbangkan. Penelitian ini bertujuan untuk mengetahui usaha perikanan budidaya udang galah di Provinsi Bali dan merancang suam sistem informasi yang berbasis Internet (Internetbase information system) mengenai usaha perikanan budidaya udang galah di Provinsi Bali. Metodologi yang digunakan dalam penelitian ini adalah Eksperimen eksploratif. Dalal1l perancangan sistem informasi ini menggunakan pendekatan tahapan Siklus Hidup Pembangunan Sistem, yang terdiri dari fase analisis, fase desain, fase inrplementasi, dan fase pemeliharaan. Hasil perancangan sistem informasi (httpj/giantprawn.hipod.com) usaha udang galah ini l1lengelol1lpokkan informasi menjadi 10 kelompok, yaitu karakteristik udang galah, upaya rintisan dan perkembangan usaha budidaya udang galah, potensi pengembangan budidaya udang galah, usaha pembenihan udang galah, teknologi anjuran usaha pembesaran udang galah, sistem pemasaran dan konsumen udang galah, biaya dan pendapatan usaha budidaya udang galah, hasil-hasil penelitian tentang udang galah, informasi lain dan kelompok disknsi udang galah (Mailing List), serta kritik dan saran.

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.
