Judul: Identifikasi Karakter Aromatik berdasarkan PCR dan Organoleptik BC3F2 Ciherang x Mentikwangi
Abstrak: Aroma character of the original Indonesian aromatic rice varieties have not been widely reported. Identification of aroma character in paddy Mentikwangi will be done using PCR with primer Bradbury and organoleptic using KOH. Use these methods are expected to select rice plants from crosses Ciherang x Mentikwangi BC3F2 be aromatic and non-aromatic, in order to obtain some new promising lines with background Ciherang carrying aromatic trait. Rice crop selection results using primer Bradbury, of the total 266 BC3F2 plants were tested, as many as 55 plants have the same sized DNA fragment with Mentikwangi about 257 bp, 34 plants have the same sized DNA fragments with Ciherang about 355 bp, and 177 plants had a heterozygous DNA fragments or a mixture of both about 355 bp and 257 bp. Organoleptic test results with 1.7% KOH homozygous recessive allele showed most flavorful score.

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.
