Judul: Perbandingan Arsitektur Informasi Repositori Institusi Terbaik di Indonesia dan Dunia
Abstrak: Sistem perangkingan repositori dapat dinilai sebagai cara untuk meningkatkan kinerja setiap institusi. Sistem perangkingan yang digunakan dalam penelitian ini berbasis Webometric versi Januari 2017. Arsitektur informasi berfokus pada sistem organisasi, sistem navigasi, sistem pelabelan dan sistem pencarian. Tujuan arsitektur informasi adalah untuk membantu pengguna mendapatkan informasi dan penyelesaian tugas. Penelitian ini menekankan kepada perbandingan kualitas arsitektur informasi pada repositori terbaik di dunia dan di Indonesia. Hasil analisis menunjukkan bahwa dari 10 menu yang paling banyak digunakan oleh repositori di Indonesia lebih cenderung menampilkan koleksi dokumen melalui menu document (collection) dengan nilai 154 sementara repositori di dunia lebih cenderung menampilkan berbagai macam pelayanan melalui menu service dengan nilai 242.

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: 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.
