Judul: Karakterisasi Ragam Genetik Ikan Sepat ( Trichogaster Pectoralis) Berdasarkan Analisis RAPD ( RAndom Amplified Polymorphic DNA) dan Morfometrik
Abstrak: Penelitian ini bertujuan untuk mengidentifikasi keragaman genetik ikan sepat yang berasal dari tiga lokasi berbeda yaitu Jawa (Tasikmalaya), Sumatra (Jambi) dan Kalimantan (Kalimantan Selatan) menggunakan metode RAPD dan karakter morfometrik. Hasil menunjukkan bahwa polimorfisme dan heterosigositas tertinggi yaitu populasi ikan sepat Kalimantan (26,67%) dan (0,12). Ukuran fragmen pada setiap populasi berkisar antara 125-2000 bp. Jarak genetik yang paling jauh adalah populasi Jawa dengan Kalimantan (0,343) sedangkan jarak genetik yang paling dekat adalah populasi Sumatra dengan Jawa (0,257). Berdasarkan uji karakter morfometrik diketahui terdapat 3 karakter yang berbeda nyata yaitu B2 (jarak antara awal sirip dorsal dengan akhir sirip dorsal), B6 (jarak antara akhir sirip dorsal dengan sirip pektoral) dan C2 (jarak antara sirip pektoral dengan sirip ventral). Hasil analisis fungsi kanonikal menunjukkan karakter morfologi ikan sepat Kalimantan memiliki nilai indeks kesamaan dengan Sepat Jawa sebesar 20%.

Judul: Analisis Ragam Genotip RAPD dan Fenotip Truss Morfometrik Tiga Populasi Ikan Gabus Channa Striata (Bloch, 1793)
Abstrak: In order to manage genetic resouces for aquaculture development of snakehead fish, the evaluation of genetic variability of three populations from different geographical areas is needed to be performed. The purpose of this study is to identify the genotype and phenotype of snakehead fish from Jawa, Sumatera and Kalimantan using RAPD and truss morphometric. RAPD method used OPA-02, OPA-04 and OPA-07 primers was conducted to type the genotypes. Twenty one measurement of truss morphometric was done on the body of fish observed. The results showed that population from Java had highest percentage of polymorphism and heterozygosity than Sumatera and Kalimantan fish population that was, 83,33% and 0,3655. The population from Kalimantan and Jawa had the highest genetic distance was 0,1908. Population from Sumatera and Kalimantan had interpopulation relationship based on the similarity of truss morphometric was 50%. Coefficien of morphometric variation data showed that population of snakehead fish from Kalimantan was higher than Jawa and Sumatera.

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.
