Judul: Faktor-Faktor yang Mempengaruhi Minat Berwirausaha Mahasiswa S1 IPB di Bidang Wisata Alam
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: The Influence of Internal and External Factors on the Entrepreneurial Interests of Students of the Faculty of Economics and Management IPB University
Abstrak: Jumlah pengangguran di Indonesia mengalami peningkatan. Salah satu langkah upaya untuk mengatasi pengangguran yaitu berwirausaha. Fakultas Ekonomi dan Manajemen (FEM) yang memiliki basis ilmu ekonomi dan manajemen, namun menurut survey menyebutkan bahwa minat wirausaha mahasiswanya rendah dibandingkan dengan fakultas-fakultas lain. Penelitian ini bertujuan untuk mengetahui kondisi faktor internal dan eksternal mahasiswa dan pengaruhnya terhadap minat wirausaha mahasiswa. Penelitian ini menggunakan data primer yang disebar melalui kuesioner pada bulan agustus 2022. Responden pada penelitian ini berjumlah 150 orang. Data dianalisis dengan menggunakan analisis deskriptif dan analisis SEM-PLS. Hasil penelitian ini menunjukkan bahwa kondisi internal mahasiswa memiliki kategori yang sangat baik yaitu sebesar 79,4 persen. Variabel harga diri, ekspektasi pendapatan, lingkungan universitas, dan lingkungan keluarga berpengaruh sigifikan terhadap minat wirausaha, namun variabel berani mengambil risiko tidak berpengaruh signifikan terhadap minat wirausaha mahasiswa FEM IPB University., The number of unemployed in Indonesia has increased. One of the efforts to overcome unemployment is entrepreneurship. The Faculty of Economics and Management (FEM) has a basis in economics and management, but according to a survey, it is stated that the entrepreneurial interest of students is low compared to other faculties. This study aims to determine the condition of students' internal and external factors and their influence on students' entrepreneurial interests. This study uses primary data distributed through questionnaires in August 2022. The respondents in this study amounted to 150 people. Data were analyzed using descriptive analysis and SEM-PLS analysis. The results of this study indicate that the students' internal condition has a very good category, which is 79.4 percent. The variables of self-esteem, income expectations, university environment, and family environment have a significant effect on entrepreneurial interest, but the risk-taking variable has no significant effect on entrepreneurial interests of FEM IPB University students.

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.
