Planets around active stars
We present the results of radial velocity measurements of two samples of
active stars. The first sample contains field G and K giants across the Red
Giant Branch, whereas the second sample consists of nearby young stars (d < 150
pc) with ages between 10 - 300 Myrs. The radial velocity monitoring program has
been carried out with FEROS at 1.52 m ESO telescope (1999 - 2002) and continued
since 2003 at 2.2 m MPG/ESO telescope. We observed stellar radial velocity
variations which originate either from the stellar activity or the presence of
stellar/substellar companions. By means of a bisector technique we are able to
distinguish the sources of the radial velocity variation. Among them we found
few candidates of planetary companions, both of young stars and G-K giants
sample.Comment: 4 pages, 5 figures, to appear in the Proceedings of the ESO Workshop

Abstract
In this project, I would like to expose the reality happening in the Indonesian society through Science fiction graphic novel script and samples. This project focuses on how the live of my main character that represent particular condition of an individual in the society. It also focuses on the surival of the character as the individual in changing her future. The theme that is used in this project is the survival of the individual. I would also explore how fear distorted human in making a crucial decision in order to survive the adverse and unusual circumstance. To depict this reality through fiction, I am using the Timepunk, a sub-genre of science fiction as the genre of my work and bringing out the issue of the cure of leukemia as the main concern of my main character
The Value Transformation of Betty Warren in Mona Lisa Smile
This study analyzes a movie entitled Mona Lisa Smile. It is interesting that the movie contains the message about women's liberation movement reflected through the value transformation done by one of the characters, Betty Warren, which is why we decided to emphasize on the transformation as our main focus. We attempt to reveal the process of Betty Warren's value transformation by applying two concepts, which are the concept of Angel in the House and the concept of New Woman. We find out that Warren's experience of value transformation goes through several stages, which are from believing in her old values, going against the new modern values, finding disappointment toward her old values, then having a conflict within herself, and as the result, starting to consider and absorb the new values. The analysis leads to the fact that patriarchal values can be so strong because sometimes, women themselves are subconsciously acting as the agents
The Reactions of the Minority Towards Racism in Crash
Crash shows the life of a community in a multicultural city of Los Angeles in a variety of separate scenes. At the end of the story will be seen a common thread that connects each of the characters and events that they experience with other characters. The interaction of the players in the movie Crash is highly dominated by racial conflict as a result of racism. In the society nowadays, most people usually see racism only by how the majority discriminate the minority like what is reflected in Crash without knowing that Crash also portrays as vividly how the minority react towards the discrimination by the majority. For this reason, I am really interested in analyzing how the minority react towards racial discrimination by the majority and how the main characters of the minority react towards racism by the majority in Crash based on John P. Myers definition of reactions which are deviance, defiance, and avoidanc
Pemodelan Pertumbuhan Ekonomi Indonesia Menggunakan Data Panel Dinamis Dengan Pendekatan Generalized Method of Moment Arellano-Bond
Pertumbuhan ekonomi merupakan Perubahan aktivitas perekonomian dalam menghasilkan tambahan pendapatan masyarakat suatu negara dalam periode tertentu. Variabel-variabel ekonomi bersifat dinamis sehingga pada penelitian ini digunakan pemodelan menggunakan metode regresi data panel dinamis. Metode regresi data panel dinamis tidak hanya untuk mengetahui efek jangka pendek (short-run effect), namun juga efek jangka panjang (long-run effect). Faktor-faktor yang diduga mempengaruhi pertumbuhan ekonomi di Indonesia adalah investasi luar negeri, pengeluaran pemerintah dan penyerapan tenaga kerja. Berdasarkan hasil analisis estimasi Generalized Method of Moment (GMM) Arellano-Bond, variabel yang berpengaruh signifikan terhadap pertumbuhan ekonomi adalah investasi luar negeri dan pengeluaran pemerintah. Selanjutnya mendapatkan pemodelan dan mengetahui elastisitas jangka pendek dan jangka panjang. Elastisitas jangka pendek investasi luar negeri sebesar 0,00269 dan jangka panjang sebesar 0,08661. Hal ini menunjukkan bahwa setiap peningkatan 10 persen investasi luar negeri suatu provinsi, maka akan meningkatkan Produk Domestik Regional Bruto (PDRB) secara jangka pendek sebesar 0,0269 persen dan jangka panjang sebesar 0,8661 persen. Elastisitas jangka pendek pengeluaran pemerintah sebesar 0,00198 dan jangka panjang sebesar 0,06384. Hal ini menunjukkan bahwa setiap peningkatan 10 persen pengeluaran pemerintah suatu provinsi, maka akan meningkatkan PDRB secara jangka pendek sebesar 0,0198 persen dan jangka panjang sebesar 0,6384 persen

Peramalan Total Market Sepeda Motor dan Total Penjualan Motor X di Propinsi Jawa Timur dengan Pendekatan ARIMA Box-Jenkins dan Autoregressive Integrated Moving Average With Exogenous Input (ARIMAX)
Pertumbuhan penduduk di Jawa Timur berdampak pada meningkatnya kebutuhan transportasi. Sepeda motor menjadi pilihan utama dikarenakan lebih murah dan efisien. Tentunya peningkatan penjualan sepeda motor memberikan keuntungan bagi produsen. Di Jawa Timur, distributor utama sepeda motor X adalah PT. Y. Penelitian ini bertujuan untuk meramalkan penjualan sepeda motor X dan total market sepeda motor di Jawa Timur, sehingga dapat diperkirakan market share penjualan sepeda motor X periode berikutnya. Metode yang digunakan dalam penelitian ini adalah ARIMA Box-Jenkins dan ARIMAX. Dalam penelitian ini, data yang digunakan yaitu data total market sepeda motor dan penjualan sepeda motor X di Jawa Timur. Data terbagi menjadi dua, yaitu in-sample periode Januari 2003 sampai dengan Desember 2013 serta data out-sample periode Januari 2014 sampai dengan Maret 2014. Hasil analisis menunjukkan bahwa model terbaik total market sepeda motor adalah ARIMA (0,1,1)(0,1,1)12, sedangkan penjualan sepeda motor X yaitu model ARIMA ([1,13],1,0)(1,1,0)12 dikarenakan memiliki nilai sMAPE terkecil berdasarkan out-sample
Pemodelan Indeks Harga Saham Gabungan (IHSG), Kurs, dan Harga Minyak Dunia dengan Pendekatan Vector Autoregressive
Vector autoregressive (VAR) merupakan salah satu analisis time series multivariate dimana dapat digunakan dalam memprediksi variabel dan berguna untuk menilai keterkaitan antara variabel. Tahapan-tahapan dalam metode VAR meliputi tahap identifikasi, estimasi parameter, dan cek diagnosa. Data yang digunakan dalam penelitian ini adalah Indek Harga Saham Gabungan (IHSG), kurs, dan harga minyak dunia pada periode 2011-2012. Dari hasil analisis didapatkan model VAR yang sesuai adalah VAR(4,1,0) dengan nilai AIC terkecil sebesar 15,7437. Selain itu hasil MAPE dan RMSE pada ketiga variabel yaitu variabel IHSG sebesar 1,85 dan 88,076; variabel kurs sebesar 0,89 dan 84,9237; sedangkan variabel harga minyak dunia sebesar 0,83 dan 0,009694
