Judul: Analisis Dan Desain Sistem Informasi Bisnis  Pada Koperasi Susu Menggunakan Uml  (Unified Modelling Language)
Abstrak: This work proposes an application for business information system in a cooperation of diary enterprise. UML (Unified Modelling Language) diagrams were deployed to analyze and design all requirements in the development by using a CASE (Computer-Aided Software Engineering) tool called Sybase Power Designer 15.3. The object oriented analysis was conducted by creating use case diagram, activity diagram, and sequence diagram. The designing process was conducted by creating a class diagram from the diagrams which are already created in the analysis. The main diagram in this research was the class diagram from which the PDM (Physical Data Model) would be generated. From this PDM, a database was generated as the inputs to this application. This system was developed by using NetBeans with MVC method, which separates the system into three components, which are the model, the view, and the controller. This system could produce reports which were generated by plug-in iReport 4.0.1. These reports are sales report, farmers report, customers report, loans report, purchasing report, remuneration report, and products report. System testing was conducted by black-box method by inputting some samples of data to the system by the user. This system should be able to manage sales data, loans data, products data, farmers data, and other transactions data

Judul: Sistem informasi bisnis berbasis UML(Unified Modeling Language) untuk agroindustri biopelet limbah pelepah sawit
Abstrak: Development of palm oil midrib biopellet business needed complete, integrated and up to date information. The objectives of this work is to identify critical factors in biopellet midrib palm oil business, to design an UML-based business information systems for biopellet agro-industry, and to evaluate the results of business information systems. The modeling is based on the object-oriented system development using UML (Unified Modeling Language) which consisted of use case diagrams, activity diagrams, collaboration diagrams, sequence diagrams, class diagrams, and physical data model. Critical factors in biopellet midrib palm oil business were the availability of raw materials or oil palm plantations, the balance of energy produced versus the energy required, the determination of industrial location, and scheduling the location of raw materials and investment feasibility. The developed business information system, more efficient in program code usage and easy to develop. Keyword: UML, biopellet, business information system, object oriented system, petiole, midrib palm oil.

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.
