Judul: Analisis Arsitektur Informasi Situs Web Universitas Terbaik di Dunia dan Indonesia Berbasis Webometrics
Abstrak: University ranking system can be considered as a method to improve the performance at each university. Two popular university ranking systems can be viewed on the site Webometrics and QS World University Rankings. There are three things that affect the rank of universities,i.e,the information architecture, the quality of the content of information, and the activities of the universities. This research emphasizes on the information of architecture by comparing the architecture of information on universities in the world and universities in Indonesia. Menus on the website of 10 universities in the world and 10 universities in Indonesia are compared based on the search level and position the menu located on each website. From the entire menu, only 30 menus are analyzed based on the highest weight values. The analysis showed that the universities in Indonesia are more likely to provide profile information, while universities in the world put forward the research and development based on user information.

Judul: Information Architecture Comparison of the World’s and Indonesia’s Best College Library Websites Based on Webometrics
Abstrak: Situs web perpustakaan perguruan tinggi merupakan sarana peningkatan efisiensi pekerjaan dan kualitas pelayanan bagi penggunanya. Untuk itu perlu diperhatikan arsitektur informasi di dalamnya yang diantaranya meliputi sistem organisasi, sistem pelabelan dan sistem navigasi. Pemeringkatan pada Webometrics menjadi salah satu acuan baik atau tidaknya arsitektur informasi pada sebuah situs web institusi. Penelitian ini membandingkan arsitektur informasi pada sepuluh situs web perpustakaan perguruan tinggi terbaik di Indonesia dan sepuluh situs web perpustakaan perguruan tinggi terbaik dunia berdasarkan tingkat penelusuran dan posisi menu yang ada dalam situs tersebut. Hasil analisis menunjukkan kecenderungan menu dan informasi yang diberikan dari masing-masing situs web perpustakaan perguruan tinggi adalah terkait Services & Tools, Collections & Resources dan Guides. Situs web perpustakaan perguruan tinggi Indonesia juga cenderung lemah dalam menyajikan menu Research yang mendapat nilai 406 dibandingkan dengan dunia yang mendapat nilai 1340., The college library websites increase work efficiency and the quality of services for its users. Therefore, it is necessary to pay attention to its information architecture, including organizational systems, labeling systems and navigation systems. Webometrics’ ranking is one of the benchmarks for good or bad information architecture on an institutional website. This study compares the information architecture of the ten best university library websites in Indonesia and the ten best university library websites globally based on the search level and the position of the menus on these sites. The analysis results show the trend of the menu and the information provided from each college library website related to Services & Tools, Collections & Resources, and Guides. Indonesian university library websites also tend to be weak in presenting the Research menu, which scores 406 compared to the world with 1340.

Judul: Mathematical model of Hematopoietic Stem Cell in Chronic Myelogenous Leukemia with and without Therapy
Abstrak: Leukemia or blood cancer is a diverse group of neoplastic disease, characterized by the multiplication of abnormal leukocytes or malignant transformation of blood-forming cells in bone marrow and lymphoid tissues. One of the most common types of leukemia is Chronic Myelogenous Leukemia (CML), which is usually diagnosed by the presence of certain chromosomal abnormalities, the so-called Philadelphia chromosome (Ph). One of the treatments of CML is Granulocyte Colony-Stimulating Factor (G-CSF). In this paper, we discuss two Hematopoietic Stem Cell (HSC) models, i.e. HSC without treatment and HSC with G-CSF treatment. The model of HSC without treatment included three equations representing the dynamics of HSC, leukocyte and platelet. Whereas, the model of HSC with G-CSF treatment includes the previous three equations and adds two more equations representing G-CSF injection and G-CSF circulation. The stability behavior of the system approaching the equilibrium points in the simulation study is carried out using Mathematica 7.0. The simulation results show that the G-CSF treatment can successfully decrease the number of HSC, which means reducing the CML.
