Judul: Studi Pelacakan Alumni Departemen Statistika FMIPA IPB (Studi Kasus pada Angkatan 36-45)
Abstrak: Department of Statistics, Bogor Agricultural University (IPB) many top producing graduates that are spread throughout the field work. One indicator of success is the contribution of graduates of higher education in society and the development and engagement of alumni in the dynamics of the workplace. Alumni tracking studies can provide information about the profile of graduates of the Department of Statistics 36-45 IPB particular class (year in 1999-2008). Alumni are expected to provide information on the relevance of knowledge and skills (relationship between competencies acquired during the lectures with field work), the relationship between grade point average (GPA) of the waiting time work, field work of alumni present, the extent to which the use/ knowledge of statistics to the field of work. Adequacy analysis, interests, and purposes related to competencies Department of Statistics. Respondents who responded to this study of 204 respondents (40.8 %) of the total population of 500 respondents. Area of origin of respondents were mostly from the Greater Jakarta area by 43.1 %, driveways Admission Exam IPB (USMI) as much as 76 %, as many as 20.1 % of respondents have a High GPA (GPA ≥ 3.51), cum laude by 5 %. The average wait for a job for 2 months with an average salary of first job after being transformed to the present value of Rp 3,370,000.00. There is a tendency of working first salary differences between respondents who have a High GPA with a low GPA. Respondents gender pay gap also has a tendency of work the first time, respondents have a tendency of female sex work first salary higher than the respondents gender male. Predicate graduation also has the distinction of first salary job, graduation cum laude predicate has a higher salary than the predicate is very satisfying and fulfilling graduation. Field work consisted of alumi academia, finance, administration, research, and advertising. As many as 40 % of alumni working in the field of research. Alumni statistics also been doing moving work, 63.3 % among respondents had changed jobs done. Statistics have a role in the world of work, amounting to 38.6 % pretty much using statistical science in the workplace. Adequacy analysis, interests, and purposes related to competencies Department of Statistics. Competency skills survey design, experimental design, data management is widely used in the field of research work.

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.
