Judul: Kajian User Experience pada Repositori Institusi Institut Pertanian Bogor
Abstrak: Institutional Repositories adalah platform pengelolaan asset pengetahuan untuk membantu institusi mengatur ruang penyimpanan yang berpusat dengan tujuan mengoleksi, mengatur, menampilkan, melestarikan dan menyebarkan artefak pengetahuan secara sistematis. Repositori IPB merupakan salah satu repositori kampus terbaik di Indonesia. Pengembangan Repositori IPB sebelumnya hanya memerhatikan dari segi fungsionalitas, sehingga masih banyak beberapa task dan konten yang dianggap membingungkan pengunjung dalam mencari suatu dokumen pada Repositori IPB. Penelitian ini berfokus pada pengembangan Repositori IPB yang memerhatikan aspek user experience (UX) menggunakan metode five plane user experience elements. Metode tersebut memiliki lima lapisan yang memiliki keterkaitan antar lapisannya. Tahap pengembangan dilakukan dari lapisan bawah menuju lapisan atas, meliputi lapisan strategy plane, scope plane, structure plane, skeleton plane dan surface plane, Setelah penelitian ini diharapkan Repositori IPB bisa mendapatkan respon yang baik dari admin dan pengunjung dengan meningkatkan layanan yang memerhatikan UX sehingga branding dan pengunjung Repositori IPB bisa terus meningkat., Institutional Repositories is a knowledge asset management platform to help institutions organize centered storage space with the purpose of collecting, organizing, displaying, preserving and disseminating knowledge artifacts in a systematic. Repository IPB is one of the best institutional repositories in Indonesia. Development of IPB Repository previously only noticed in terms of functionality, so many multiple tasks and content considered to confuse the visitor in finding a document on IPB Repository. This research will be focusing in aspect of user experience (UX) using five planes user experience elements to development IPB Repository. The method has five layers that have linkages between the layers. The development phase is done from the bottom layer to the upper layer, includes layer strategy plane, scope plane, structure plane, skeleton plane and surface plane. After this research will expect Repository IPB can get a good response from the admin and visitors by improving services noticed UX so that branding and visitors Repository IPB increase significantly.

Abstrak: Institutional repository is a repository of digital collections published by institutions. Institutional repository is important as a container store and preserve collections produced by the institution. However, before developing the institutional repository feasibility study needs to ensure that the development process will be able to run well. The purpose of this study is to assess/feasibility study analysis in the development of institutional repositories at ITD and make a recommendation for the development of institutional repositories at ITD. Institutional repository element studied is the infrastructure, human resources, budget, rules/SOP, and content. IPB repositories use as a model in this research. The method used is knowledge management systems (KMS) in stages 1 and 2. Weighting interests repository elements using AHP (Analytic Hierarchy Process). The weighting for each component element of institutional repository based on the opinion of experts, the assessment of the four elements are as follows institutional repository infrastructure (22.23%), content (21.32%), rule / SOP (20.00%), human resources (19.36%), budget (16.99%). Based on the weighting that the most important component in building repository is infrastructure and the last one is the budget. Based on the analysis of the feasibility of the ITD infrastructure percentages obtained in building institutional repositories amounted to 51.96%. The percentage is derived from the percentage of the value of the following eligibility is infrastructure (21.44%), human resources (14.33%), budget (0%), rules / SOP (3.40%), and content (12.79%). While the results of the alignment of the management of knowledge shows that knowledge in IPB and ITD focuses on strategies codification where codification in IPB done by (89%) and in the ITD by (78%). This shows that both IPB and ITD focus on storage technology knowledge management, indexing, retrieval and reuse of knowledge that is stored. Furthermore, if the IPB has had a team in developing the knowledge, the ITD has the potential to have a team that consists of a collaboration between Library and Resource Information Team (SDI) ITD. The results of the study referred to the several things that need to be ordered in the effort to develop the institutional repository ITD and refer to the model repository development in IPB is to provide the infrastructure that is software as a tool for transferring media content repository, making decree for institutional repository development team, create standard operational procedure for digital documents and the handover of the scientific work of the academic community ITD and make decree for deposit of scientific work and submit a budget for activities of institutional repository.

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.
