Judul: Penggunaan Distillers Dried Grains with Solubles (DDGS) dan hominy feed pada pakan ikan kerapu bebek cromileptes altivelis
Abstrak: DDGS is a by-product in the production of bioethanol that is mainly derived from corn, while the hominy feed is a by-product of corn milling process on the production of corn flour for food. This study aims to examine the influence of the use of DDGS and hominy feed on the growth performance of humpback grouper Cromileptes altivelis. This research was conducted in June to October 2010 in floating net cage in Suak Panjang, Pahawang Island, Punduh Pidada sub-district, Pesawaran district, South Lampung and Fish Nutrition Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University. This research used experimental methods Completely Randomized Design (CRD) with three treatments and two replicates respectively. The treatment in this study namely Diet A (diet without DDGS and hominy feed), Diet B (diet with DDGS and hominy feed 10%), and Diet C (diet with DDGS and hominy feed 19%). Fish weights 11.6-14.6 gram were reared in net cage (3x1x2)m3 at densities of 55-56 fish/m2. Fish were fed 3 times daily at satiation level. In ordered to keep fish in good condition net cage were wash weekly. The results showed that fish fed Diet B (DDGS and hominy feed 10%) have similar growth performance to those fish fed Diet A and higher when being compared to the rest. It is concluded that DDGS and hominy feed at the level of 10% can be used in the diet of humpback grouper.

Judul: Growth Response, Biochemical Composition and Innate Immunity of the Juvenile Humpback Grouper after Treatment with Recombinant Growth Hormone.
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).

Judul: Analisis dan Implementasi Certificate Authorities (CA) pada Public Switched Telephone Network (PSTN)
Abstrak: Secure Telephone Protocol has ability to authenticate involved party and keep the secrecy of the message sent over the protocol. The secrecy of the message archieved by using symmetric key cryptographic scheme, and authentication archieved using public key cryptographic scheme. One of several party involved in the protocol and hold an important function called Certificate Authorities or CA. CA responsible for generating public key pair for other party involved in the protocol. When CA generates public key pair, several primitive cryptographic scheme used for guarantee the security of the key. Two of them are hash function SHA-1 and El-Gamal public key scheme embedded in Digital Signature Algorithm scheme. The prototype implementing the scheme above developed using Java programming language with JCE addition from Bauncy Castle. The analysis towards implemented prototype indicates that the prototype still has some flaws to be implemented in real world.
