Judul: Representasi Word Graph Menggunakan XML untuk Kata Benda dalam Bahasa Indonesia
Abstrak: Grafik pengetahuan merupakan salah satu metode yang dapat merepresentasikan semantik suatu bahasa. Dalam bahasa alami, ada banyak kasus di mana makna sebuah kalimat bersifat ambigu. Representasi grafik pengetahuan yang digunakan dalam bahasa alami dapat mengatasi masalah ini. Salah satu bagian terkecil dari grafik pengetahuan adalah grafik kata. Grafik kata adalah grafik yang merepresentasikan makna sebuah kata. Pada penelitian ini, kami merepresentasikan grafik kata untuk kata benda bahasa Indonesia menggunakan eXtensible Markup Language (XML). Dengan menggunakan XML, data dapat dengan mudah dipertukarkan dan menyediakan data yang lebih dinamis. Terdapat 20 pola grafik kata nominal yang digunakan dalam penelitian ini. Semua pola tersebut dihasilkan dari penelitian sebelumnya. Setiap dokumen XML memiliki elemen root yang disebut elemen grafik. Elemen grafik memiliki dua elemen turunan, komponen dan hubungan. Komponen berisi semua komponen yang membentuk grafik kata, dan elemen relasi berisi semua relasi yang ada dalam grafik kata. Grafik pengetahuan kata benda bahasa Indonesia telah berhasil direpresentasikan dalam XML. Hasil dari penelitian ini adalah 20 dokumen XML pola grafik kata nomina bahasa Indonesia, dan setiap dokumen XML sesuai dengan pola asli pada penelitian sebelumnya.

Judul: Representasi Word Graph Menggunakan XML untuk Kata Sifat dalam Bahasa Indonesia
Abstrak: Knowledge Graph (KG) is a method in natural language processing. A part of knowledge graph is known as word graph, a graph which describes the semantic of a word. In this research, we represent word graphs for Indonesian adjectives using eXtensible Markup Language (XML). XML is used to provide facilities in the publication and exchange of data for the next research. Indonesian adjectives in this research are based on the third edition of Kamus Besar Bahasa Indonesia (KBBI). The general pattern in adjective word graph consists of 20 patterns generated from previous research. KG concept has successfully represented in XML forms to facilitate the exchange of data. The result of this research are 21 documents formated in XML forms and the testing result has an accuracy of 100%.

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
