Judul: Abstraksi teks berbahasa Indonesia menggunakan teori knowledge graph
Abstrak: Text summarization system has been developed in order to select several sentences based on certain criteria. However, this method tends to omit some informations contained in unselected sentences. Therefore, a system is needed to get a text abstraction, which represents the whole informations contained in the original text. Knowledge graph offers the way to built such system. Knowledge Graph is a new method in Natural Language Processing (NLP) that represents a knowledge in a form of graph. Using this method, every sentence in the full text version can be represented into graphs which can be further analyzed and gathered into a single graph that describes the meaning of the full text. The result of this research is a procedure to implement knowledge graph theory to get an abstraction 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: Provision of vaccine effectiveness against Ichthyophthirius multifiliis common carp (Cyprinus carpio L) at different temperatures of media
Abstrak: The aims of this study were to assess the physiological and haematological responses of fish due to different water temperatures, Ichthyophthirius multifiliis (ich) infection, and vaccination with ich theront stadia. The research was conducted in three stages. The first stage was designed to determine the temperature range that could cause stress in fish and had potency to cause ich infection. In the second stage, fish was infected with ich. The last stage was carried out to investigate the effect of vaccination. Physiological changes in fish from each stage were determined. The results of the first stage showed that cortisol levels at 20, 24, and 28⁰C and glucose levels at 24 and 28oC increased until 21st day. Fish that was kept at 24oC had the lowest survival rate (87±3.35%) and fish that was kept at 32oC had the highest survival rate (100%). In the second stage, infected fish at 20oC was under great stress, which was characterized by the increase in cortisol levels by 51.38% on 3rd day, increase in glucose levels by 60.93%, decrease in osmolarity by 18.40%, decrease lymphocytes percentage by 16.44%, and the lowest survival rate (58.11±2.16%). The damage that was affected by I. multifiliis could be seen by the presence of hypercellular, many goblet cells, and infiltration of lymphocytes cells. Lastly, vaccination caused the decrease in cortisol levels and increase in glucose levels until 14th day. The prevalence of I. multifiliis in the vaccinated fish decreased with the increase in temperature, and I. multifiliis prevalence at 20⁰C was 80.03±10.00% and at 28⁰C was 0%, and the highest survival rate was obtained at 28⁰C (100%).
