Judul: Isolasi dan karakterisasi cDNA hormon pertumbuhan ikan kerapu bebek (cromileptes altivelis)
Abstrak: Hormon pertumbuhan (GH) merupakan protein 22 kDa pituitari yang terkonservasi akibat evaluasi vertebrata. Hormon pertumbuhan ikan berperan dalam pertumbuhan, adaptasi air laut, reproduksi dan fungsi imun. Kerapu bebek (C.altivelis) adalah salah satu ikan air laut yang mempunyai nilai ekonomis penting.

Abstrak: Ikan kerapu bebek Cromileptes altivelis (Valenciennes, 1828) adalah salah satu jenis ikan laut bernilai ekonomi tinggi untuk ekspor ikan hidup yang dibudidayakan di Indonesia. Problem utama budidaya ikan kerapu bebek adalah pertumbuhannya yang lambat, sehingga perlu upaya mempercepat pertumbuhannya untuk efisiensi ongkos produksi dan menekan risiko kegagalan. Seiring dengan berkembangnya bioteknologi modern, pertumbuhan dapat dipercepat dengan memanfaatkan hormon pertumbuhan rekombinan. Penelitian ini bertujuan untuk menguji respons pertumbuhan, komposisi biokimia dan imunitas bawaan benih ikan kerapu bebek setelah perlakuan hormon pertumbuhan rekombinan ikan kerapu kertang Epinephelus lanceolatus (rElGH)., The humpback grouper Cromileptes altivelis (Valenciennes, 1828) is one of the most expensive marine fish cultured in Indonesia. The main problem encountered in the culture of this species is its low growth rate, therefore effort to fastening growth rate was needed for making aquaculture more efficient in terms of minimizing cost production and risk. With the development of modern biotechnology, growth has been improved through the use of various preparations of exogenous homologous or heterologous growth hormone (GH). In the present study, we investigated the growth response, biochemical composition and innate immunity of the juvenile humpback grouper after treatment with recombinant Epinephelus lanceolatus growth hormone (rElGH).

Abstrak: Traffic flow phenomenon can be described through mathematical model such as continuous dynamic model with an ordinary differential equation so that it can be solved with integral factors. In this paper three simple models of traffic flow are discussed, i.e, two macroscopic and one microscopic models. Macroscopic model formulates dynamics of the traffic flow that occurs on a large number of vehicles on a road. While the microscopic model explains drivers’ behavior in their interaction with other vehicles ahead, i.e, car-following model. This paper shows the existence of ordinary differential equation found in the traffic flow model and indicates some different representations in the context of the same model. It also reviews a simple model of traffic flow along a single link, which leads to some unexpected results, i.e, it can express the solution model in term of link outflows as well as trip time. In the microscopic model, simulation is done to illustrate the behavior of the drivers with a sensitivity coefficient as a benchmark parameter.
