Judul: Perancangan Aturan Abstraksi Teks Berbahasa Inggris Menggunakan Metode Knowledge Graph
Abstrak: Reading the whole text of document could take a long time. There has been developed a method of summarizing text. However this method loses a large amount of information content in text so that get an overview of the contents of the text.

Judul: Implementasi Knowledge Graph untuk Abstraksi Teks
Abstrak: Knowledge is an important factor in human life. Knowledge can be obtained from various sources and one of them is from a text. The text used in this study is Indonesian text on food security. To gain knowledge in the text, we use a so called Knowledge Graphs (KG) method. This study implements KG method in selecting sentences to represent the knowledge contained in the text. The selection of the sentences in the text is based on the number of nouns in each sentence and position of main sentence in the paragraph. Generally, we select about half of the number of the sentences in each paragraph. In this research, we used four texts on food security; three texts for experimenting and one text for testing. Since some of the sentences were discarded from the paragraph, the selection process caused loss of information in the text. However, the method is relatively simple since only few sentences need to be transformed into a graph. For the long time goal, KG is believed to be a potential method for developing an abstraction system for Indonesian text.

Judul: Bivalent vaccine for Motile Aeromonas Septicemia and Streptococcocis in Nile Tilapia (Oreochromis niloticus)
Abstrak: Etiological agents of common fish diseases are the Gram-negative Aeromonas hydrophila and the Gram-positive Streptococcus agalactiae, both are considered severe fish pathogens on account of their ability to cause damaging disease outbreaks in Nile Tilapia (Oreochromis niloticus). The occurence of co-infections between A. hydrophila and S. agalactiae at Waduk Cirata was about 20% per populations. Clinical signs appeared soon after infection, and include depression or excitability, anorexia, C-shaped body posturing, erratic swimming and whirling, and death. Aeromonas hydrophila and S. agalactiae cultures were not able to inhibit each other and showed negative results from antimicrobial activity, both are succeptible to antibitoics Tetracycline and Chloramphenicol. Nile Tilapia also were clinically examined and necropsied for histopathology, samples were taken from kidney, brain, liver, and spleen. Histopathological lesions were grouped into two characteristic patterns. The first pattern consisted focal lesion and inflammation. The second pattern consisted of multifocal lesion, necrotic, and inflammatory lesions resulting organ deformation. The mortality patterns of Nile Tilapias showed acute and chronic infections to Motile Aeromonas Septicemia, sub-acute infection to Streptococcocis. There was a homeostatic balances on hematological respons during co-infection. Aeromonas hydrophila AHL0905-2 and Streptococcus agalactiae N14G, were used as an inactivated A. hydrophila and S. agalactiae vaccine. Different vaccine preparations and formulations for vaccination of Nile Tilapia species were tried by adding neutral buffered formalin 3% to the bacterial culture (bacterin). The safety of formalin inactivated vaccine is still questionable by some aquaculture practitioners, but the sterility and safety test results of the bivalent vaccine was safe to use through intraperitoneal injection route. An antibody response was detected at the 1st week that rose significantly (p<0.05) at the 3th week post immunization in all the immunized groups. Similarly, there were significant difference (p<0.05) in the humoral immune response between groups immunized with single and mixed bacterial antigens. Upon challenge with single pathogen, a high relative percent survival was recorded in the group immunized with mixed bacterial antigens and was comparable to those fish immunized with the single bacteria. The value of relative per cent survival from bivalent vaccine mixed whole cell+ECP was 100% and 86.2% to single infections and 56.7% to co-infections, indicate that this vaccine was eficient in Nile Tilapia.
