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 Karakter Aromatik secara Molekuler dan Organoleptik pada Galur Padi BC5F2 Hasil Persilangan Ciherang dan Pandanwangi
Abstrak: Aroma in rice has become an important consideration in increasing consumer appetite. Genetic mapping of molecular marker related to the responsible for fragrance in rice was previouslyreported and it was closely linked with microsatellite marker RM223. This study aimed to identify the aromatic character of the gene badh2 in BC5F2 populations derived from crosses between Ciherang and Pandanwangi, both with molecular marker RM223 and organoleptic analysis using KOH 1.7% solution. Based on the foreground selection analysis of the total 272 individual tested lines, 105 lines were found to be homozygous for Pandanwangi (160 bp), 46 lines were homozygous for Ciherang (140 bp) and 121 lines were heterozygous (140 bp and 160 bp). Evaluation of aroma with KOH in selected BC5F2 lines showed variation in quality value, such as slight, moderate, and strong aroma. Thus, through these two selection methods, we were able to select several BC5F2 lines carrying aromatic trait introgressed from Pandanwangi at target region.

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.
