Judul: Feasibility Common Currency pada ASEAN+6 : Analisis Generalized Purchasing Power Parity dan Konvergensi Kurs
Abstrak: Deepening economic integration in ASEAN+6, bring up the idea to form a common currency in this region. Therefore, this study aims to analyze the feasibility to establish a common currency in ASEAN+6 and determine the appropriate currency used as a common currency. The data used in this study are monthly time series data from January 2000 to June 2012. Generalized Approach Purchasing Power Parity (G-PPP) analysis using the Vector Error Correction Model (VECM) method was conducted to answer the first goal. The results show the validity of the G-PPP and Optimum Currency Area in ASEAN+6. Therefore, ASEAN+6 as a whole, could make preparations to conduct monetary union step by step. Subsequently, a second analysis is exchange rate convergence analysis, which is to determine which currency is suitable to be used as a common currency in this region. In this analysis U.S. Dollar, Chinese Yuan, and Japanese Yen are used as based currencies. The selection of those currencies were based on previous studies. The results show that the co-movements of ASEAN+6 countries currency have a strong relationship with U.S. Dollar compared to Chinese Yuan and Japanese Yen. Furthermore, this study suggests the use of China's Yuan as a common currency in ASEAN+6.

Judul: Aplikasi statistika dalam mengkaji kemungkinan pembentukan mata uang ASEAN (ASEAN currency Unit)
Abstrak: Gagasan pembentukan mata uang tunggal di kawasan ASEAN dilatarbelakangi oleh trauma krisis ekonomi di Asia tahun 1997, sehingga apabila terjadi di kemudian hari, negara ASEAN akan lebih kuat dalam menghadapi guncangan yang terjadi. Kecenderungan peningkatan integrasi perdagangan dan keuangan regional di belahan dunia telah mendorong kawasan ASEAN+6 untuk meningkatkan proses kerjasama di wilayah tersebut, seperti yang telah dilakukan negara-negara Eropa. Dengan harapan memiliki kesuksesan yang sama dengan mata uang Euro, maka mendorong negara ASEAN melakukan hal yang serupa yaitu membentuk mata uang ASEAN (ASEAN Currency Unit). Pembentukan mata uang ASEAN ini dengan mengadopsi pembentukan mata uang Euro yaitu dibentuk dari sekumpulan mata uang yang terdiri dari kombinasi linear mata uang negara-negara di ASEAN+6 dengan bobot tertentu, dengan metode weighted average dan analisis komponen utama. Selain itu, diidentifikasi masing-masing negara ASEAN+6 apabila adanya guncangan dari mata uang ASEAN, US Dollar dan Euro, dengan melihat Impulse Response Functions. Hasil pembentukan ASEAN Currency Unit (ACU) yang paling stabil diperoleh dari metode weighted average, dimana pembobotnya adalah volatilitas dari nilai tukar mata uang ASEAN+6. Dengan pembentukan ACU tersebut, negara Indonesia, Malaysia, Singapura, Filiphina, Thailand, Vietnam dan China memiliki manfaat besar apabila ikut serta dalam pembentukan ini, yang dapat dilihat dari grafik Impulse response Functions. Hal ini dikarenakan nilai tukar mata uang negara tersebut mengalami kestabilan apabila terjadi guncangan dengan mata uang ACU.

Judul: Aktivitas Sitotoksik dan Apoptosis Sel Khamir Ekstrak Kloroform Kapang Endofit Evodia suaveolens
Abstrak: Cancer can occur if the cell cannot be sustained in the amount fixed. Cells that have failed apoptosis, they will division continously. Apoptosis is the process of programmed cell death. Apoptosis in yeast cell can be used as model because yeast cell cycle similar to human cell. Evodia suaveolens produce evodiamine, it trigger apoptosis. Endophytic mold produce bioactive compounds that similar to its host plant. Eight isolates endophytic mold have been isolated from steam of Evodia suaveaolens. Endophytic mold then was fermented and secondary metabolites was extracted with chloroform. Then the extracts was tested using cytotoxic activity with BSLT (Brine Shrimp Lethality Test) method. Values of LC50 from each endophytic mold of Evodia suaveolens are 315 ppm (mold 1), 270 ppm (mold 3), 400 ppm (mold 5), 19.7 ppm (mold 7), and 403 ppm (mold 8). Mold 2,4, and 6 is not toxic in 500, 100, 50, and 10 concentration. Each concentration of LC50 used for apoptosis induction in yeast cell. Percentation of yeast cell that have petite from mold 1, mold 3, mold 5, mold 7, and mold 8 are 69%, 75%, 86%, 90%, and 90.4% respectively. This percentation showed that isolate 1, 3, 5, 7, 8 from endophytic mold Evodia suaveolens can induction apoptosis in yeast cell.
