Abstrak: Nowdays colleges are required to prepare students to be an entrepreneurs (job creator), not just as a job seeker. Bogor Agricultural University (IPB) has a vision to be an university with an entrepreneurial character to produce graduates who can manage natural resources well, one of them for natural tourism. The aims of these research were to knowing about IPB students interest in entrepreneurship and to identify the factors that influence it. Data collection in this research used a questioner and interview method. Analysis technique in this research used descriptive analysis and inferential analysis (correlation test and multiple linear regression). The result of this research showed that student interested in entrepreneurship, which is known that in good category has average score 69.89 percent. Result of this research also showed that almost students (88%) expressed interest in entrepreneurship in the field of natural tourism. The factors that affect of entrepreneurial interest is family environment, social environment, educational environment, and entrepreneurship experience.

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.
