Judul: Evaluasi marka simple sequence repeat (ssr) untuk membedakan 17 genotip klon karet (hevea brasiliensis).
Abstrak: Masa seleksi tanaman karet (hevea brasiliensis) secara konvensional tergolong cukup lama sekitar 25-30 tahun, sehingga dibutuhkan identifikasi secara molekuler untuk mempercepat masa seleksi. Marka ssr merupakan marka polimorfis, kodominan dan sudah banyak digunakan pada penelitian dna tanaman karet. Penelitian ini dilakukan untuk mengevaluasi kemampuan sembilan pasang marka ssr dalam membedakan tujuh belas klon tanaman karet (hevea brasiliensis) melalui pola pita hasil pcr ssr dan nilai pic-nya. Berdasarkan nilai pic dan skoring, kesembilan primer ini dapat mengamplifikasi sebagian besar klon karet yang digunakan dalam penelitian ini namun hanya enam primer yang dapat digunakan untuk membedakan klon karet sehingga dapat dimanfaatkan dalam mempercepat proses seleksi tanaman karet.

Judul: Seleksi Primer Simple Sequence Repeat (SSR) untuk Identifikasi 17 Klon Karet (Hevea brasiliensis)
Abstrak: Rubber tree (Hevea brasiliensis) breeding have problem because it takes long time and wide area to select new superior clones. On the other hand, the effort to increase rubber trees planting is not followed by availability of original clone seeds. Quick and accurate identification is needed to solve these problems. One of strategy that can be used to solve these problems is by using Simple Sequence Repeats (SSR) molecular marker. The aim of this research was to select SSR primer that identify the 17 rubber clones specifically by its DNA pattern and polymorphism degree. Nine primers used to amplified the 17 DNA of rubber clones. SSR results was evaluated by 3% agarose and 6% polyacrilamide. Eight of nine primers in this research can identify some rubber clones. Those primers are SSRH403, SSRH548, gSSR165, gSSR212, gSSR268, EHB109, EHB169, and HBE280. The most informative primer that is SSRH403 (PIC: 0.7069) can identify five clones, while the weakest primer that is HBE280 (PIC: 0) can identify just one clone.

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.
