Judul: Analisis Permintaan Uang dan Disinflasi di Negara ASEAN : Analisis Data Panel
Abstrak: This study empirically examines the state of inflation and the factors that affect the long-term money demand in ASEAN countries (Indonesia, Malaysia, Philippines, Singapore, and Vietnam) during January 2008 to March 2013. This study was performed using a panel cointegration. The results showed that a decline in the rate of inflation (disinflation) in the country from January 2009 to September 2009. In addition, the results also indicate that the demand for money is significantly influenced by the domestic interest rate (proxied by the deposit rate) and output (proxied by manufacturing production index).

Judul: Analisis Faktor Ekonomi yang Mempengaruhi Laju Inflasi Negara Anggota ASEAN dengan Regresi Data Panel
Abstrak: Panel data regression model is the regression model using panel data which is a combination of cross section data and time series data. To estimate the panel data regression model, there are 3 approaches, those are pooled least square, fixed effect model, and random effect model. Parameters on pooled least square approach be estimated by Ordinary Least Square (OLS) method. On fixed effect model approach, parameters be estimated by OLS with the addition of dummy variable. Parameters on random effect model be estimated by Generalized Least Square (GLS). This research aims to estimate the panel data regression model to the data rate of inflation percentage of ASEAN member countries in 2000-2008 to know the economic factors that affect the inflation rate. The results of panel data analysis shows that the appropriate panel data regression model for these data is the fixed effect model with weighting (cross section weights) and white heteroscedasticity. This model indicates that the Consumer Price Index and money growth significantly affected the inflation rate of the ASEAN member countries.

Judul: Pembentukan Tanaman Haploid Ganda dengan Perlakuan Oryzalin Secara In Vitro pada Biji Jagung (Zea mays) Diduga Haploid
Abstrak: BC2 maize purple kernels estimated haploid were resulted from a cross between Bisma variety with haploid inducer line (3490) by backcross. Chromosome doubling to these kernels was done to produce doubled haploid plants (pure lines). This study was conducted to get an in vitro diploidisation method by oryzalin treatment as a chromosome doubling agent, with concentration of 0, 5, 10, and 15 mM for 24 hours on seeds and root of seedlings. Chromosome analysis on the control of purple kernels showed 66.7% of the seeds was haploid and 33.3% was diploid. Oryzalin treatment affected in doubling the chromosome number from haploid to doubled haploid or from diploid to tetraploid. The higher concentration of oryzalin increased the opportunity of chromosome doubling, but increased death rate. Combination of treatment that is most efficient was 5 mM oryzalin on seedling roots that produced the highest number of doubled haploid plants was found by 71.4% with a low mortality rate by 30%. Increasing of the chromosome number caused the growth of the longer canopy length and more number of leaves and the lower stomata density.
