Judul: Seleksi Primer RAPD-PCR untuk Menampilkan Pola Pita DNA Meniran (Phyllanthus sp.) dan Kapulaga Lokal (Amomum cardamomum).
Abstrak: Phyllanthus sp. (meniran) and Amomum cardamomum (local cardamom) are widely used as herbal medicinal plant in Indonesia. Exploration of genetic information of these plants is needed for developing prime seeds for herbal medicinal plant. The objective of this research was selecting some RAPD random primers to generate amplicons that can show DNA bands pattern of some meniran and local cardamom samples. Optimization of RAPD-PCR was performed on samples of meniran indicating the absence of DNA amplified using universal primers OPE-19 and OPH-5, while for the optimized sample cardamom (cardamom red) showed the amplified DNA. RAPD primer used about 20 of OPA-OPD series 11-15. Results showed that 15 primers were successful in amplifying the local cardamom DNA detected by agarose gel 1.5%.

Judul: Analisis Keragaman Genetika Tanaman Kunyit dan Temulawak secara Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) Menggunakan Primer OPA-OPD 6-10
Abstrak: There are many studies on turmeric (Curcuma domestica Val.) and wild ginger (Curcuma xanthorrizha Roxb.) from Indonesia is only about the content of secondary metabolites, but research on the genetic diversity information of turmeric and wild ginger plants has never been done before. This study was aimed to analyze the fingerprint pattern of Indonesian native turmeric and wild ginger plants by using OPA-OPD 6-10 primer series to obtain a phylogenetic tree of these plants. The steps of this research were DNA isolation, amplification of DNA, then analysis and construction of phylogenetic trees using the UPGMA (unweighted pair group method arithmetic mean) with NTSYS software. The resulted DNA showed good bands and had a size between 11000-12000 bp with the range of purity between 1091-2625. DNA amplification with 20 random OPA-OPD 6-10 primers produced 259 bands (100% polymorphic). Analysis of genetic similarity indicated a genetic similarity coefficient 0.3033-0.6721 for turmeric plant and 0.1939-0.9082 for wild ginger plant. This value indicated that the turmeric and wild ginger plants from Indonesia has a high level of genetic diversity.

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.
