Judul: Introduksi Gen Aroma (badh2 Termutasi) dari Varietas Pandan Wangi atau Mentik Wangi ke Ciherang
Abstrak: Aroma wangi merupakan karakter potensial pada padi kualitas tinggi yang permintaannya semakin meningkat. Permintaan tersebut sangat tinggi di pasaran Asia dan di seluruh dunia. Perbaikan varietas aromatik baru dengan karakter agronomi sebaik varietas nonaromatik merupakan langkah yang prospektif untuk meningkatkan produksi dan pertanian di Indonesia. Penelitian ini merupakan bagian dari usaha pengembangan varietas aromatik baru nontransgenik dengan mengintroduksikan gen aroma padi (badh2 termutasi) varietas aromatik (Pandan Wangi atau Mentik Wangi) ke varietas nonaromatik (Ciherang). Metode persilangan terarah (site-directed crossing) digunakan untuk menyilangkan tanaman hasil penelitian sebelumnya, yaitu BC3F1 Ciherang/Pandan Wangi (CP) dan BC2F1 Ciherang/Mentik Wangi (CM) untuk menghasilkan tanaman BC4F1 CP dan BC3F1 CM. Seleksi dilakukan menggunakan PCR dengan marka RM223 untuk CP dan marka Bradbury untuk CM. Sampel DNA padi hasil isolasi dari daun muda diamplifikasi dengan PCR dan produknya dielektroforesis agarosa 3% untuk CP dan 1.5% untuk CM. Hasil amplifikasi DNA tanaman padi BC3F1 CP menggunakan marka RM223 dapat membedakan pola pita padi aromatik dan nonaromatik dengan ukuran pita sebesar 140 bp dan 160 bp. Hasil amplifikasi DNA tanaman padi BC2F1 CM menggunakan marka Bradbury menghasilkan pita berukuran 580 bp, 355 bp, dan 257 bp. Pita heterozigot yang terbentuk menunjukkan keberhasilan introgresi gen aroma (heterozigot badh2) dari Pandan Wangi atau Mentik Wangi ke Ciherang.

Judul: Identifikasi Gen Aroma Pada BC5F1 Ciherang-Pandan Wangi dan BC4F1 Ciherang-Mentik Wangi
Abstrak: The demand of high quality rice becomes increasingly in Asian market and around the world. The increase in productivity and quality of Indonesian agriculture has continued, such as improving new aromatic rice variety to have good characteristics (resistant to pest, ) which is like non-aromatic rice. The aim of this research was to develop new varieties of non transgenic aromatic rice by induction of aroma gene (mutated badh2) from aromatic varieties (Pandan Wangi or Mentik Wangi) to non aromatic varieties rice (Ciherang). Rice BC5F1 CP (Ciherang/Pandan Wangi) and BC4F1 CM (Ciherang/Mentik Wangi) that used in this research were the result from previous research with site-directed crossing method. Selection of plant was done by PCR with RM223 marker for CP and Bradbury marker for CM. Visualization of DNA sample by PCR was done by using gel agarose 3% for CP and 2% for CM. DNA amplification result of BC5F1 CP with RM223 marker can distinguish the band pattern of aromatic and non aromatic with band size 140 bp and 160 bp. In addition, DNA amplification result of BC4F1 CM with Bradbury marker produced DNA band size 580 bp, 355 bp and 257 bp. The succeed in introgression of aroma gene from Pandan Wangi or Mentik Wangi to Ciherang was showed by heterozygote band.

Judul: Dynamic New Keynesian Model for Unemployment and Inflation Rate.
Abstrak: This paper deals with a scientific analysis of the equilibrium level of hiring, employment and unemployment. The basic model being used is a standard new Keynesian model, which states that utility function depends on consumptions and working hours. Utility maximization refers to a standard labour supply equation, with the marginal cost’s dynamics on new Keynesian model simply reflects movements in real wages and productivity. Furthermore, trade-off between output and inflation stabilization can be considered using the new Keynesian Phillips curve. Dynamic general equilibrium model is a model that can be used to study interactions between market imperfections and nominal rigidities, which is capable of overcoming the main shortcoming of the standard new Keynesian model. In the general equilibrium model there are three groups of the economy agents, namely households, firms and monetary authority. The results of this research science that bargaining processes between firms and workers will yield optimal wage. Increase in labour will cause wages to fall, but the unemployment rate can be reduced. An increase in the firm’s monopoly power will shift the labour demand curve downward, which will reduce the number of workers that firm is willing to hire for any given bargained wage.
