Judul: Karakteristik Gen Cytochrome Oxidase subunit I (COI) Parsial pada Amfibi (Famili: Ranidae) di Kampus IPB Dramaga sebagai Dasar Konservasi Genetik
Abstrak: Amfibi memiliki sensitivitas metamorfosis yang tinggi terhadap kualitas suatu perairan di habitatnya, sehingga menjadikan amfibi sebagai organisme bioindikator dari suatu perairan. Data molekuler suatu organisme sangat dibutuhkan sebagai dasar penentuan upaya pelestarian spesies khususnya pada aspek konservasi genetik. Tujuan penelitian ini untuk mengkarakterisasi susunan basa nukleotida dan menganalisis hubungan kekerabatan antar-spesies dari famili Ranidae asal IPB University berdasarkan gen COI. Sampel penelitian terdiri dari tiga spesies famili Ranidae di IPB University. Urutan basa Ranidae didapatkan melalui tahapan ekstrasi DNA, amplifikasi, dan sekuensing. Urutan basa yang telah disejajarkan dengan sekuen jenis lain kemudian dianalisis untuk menghasilkan informasi berupa: karakteristik genetik, jarak genetik, hubungan kekerabatan, keragaman haplotype, dan jarak berpasangan (Fst). Hasil penelitian menjelaskan bahwa tiga spesies famili Ranidae di IPB University terpisahkan secara jelas dan memiliki hubungan dekat berdasarkan jarak genetik dan pohon filogenetika dengan dua situs spesifik bersifat konservatif.

Judul: Characteristic of Nucleotide Sequence of COI Gene of Blue Swimming Crab Portunus pelagicus (Linnaeus, 1758) for Fisheries Management in WPP-NRI 711
Abstrak: Sumberdaya perikanan Indonesia yang bersifat multispesies dapat menimbulkan fenomena cryptic dan complex species, sehingga dibutuhkan metode yang akurat dalam pemastian spesies rajungan, yaitu dengan DNA barcoding. Penelitian ini bertujuan menentukan kepastian spesies dan menganalisis kondisi populasi rajungan (Portunus pelagicus) di perairan WPP-NRI 711 berdasarkan gen COI. DNA contoh rajungan berjumlah 10 individu yang didapatkan dari tiga lokasi, yaitu perairan Bintan, Bangka, dan Ketapang telah diisolasi. Kualitas untaian DNA yang baik digandakan dan diurutkan pada proses sekuensing. Seluruh contoh rajungan tervalidasi secara genetik sebagai spesies Portunus pelagicus. Komposisi basa nukleotida dari contoh rajungan didominasi oleh pasangan basa adenin-timin. Keragaman genetik rajungan di perairan Ketapang dan Bintan tergolong tinggi, sedangkan di perairan Bangka tergolong sedang. Ketiga lokasi penelitian memiliki nilai Fst yang tergolong rendah. Hasil penelitian menunjukkan bahwa populasi rajungan berada pada kondisi yang baik., Indonesia's multi-species fisheries resources can cause cryptic and complex species phenomena, so an accurate method is needed to determine the blue swimming crab species, such as DNA barcoding. This study aimed to determine the species certainty and to analyze the population status of blue swimming crab (Portunus pelagicus) based on the COI gene in WPP-NRI 711. A total of 10 blue swimming crab samples DNA obtained from three locations such as Bintan, Bangka, and Ketapang waters was isolated. High quality DNA strands are duplicated and sequenced. All of the samples have been genetically validated as Portunus pelagicus species. The nucleotide base composition of the COI gene from samples was dominated by adenine-thymine pairs. The genetic diversity value in Ketapang and Bintan are high, while in Bangka is moderate. All sampling sites have a low fixation index value. It can be concluded that the blue swimming crab populations are in a good condition.

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.
