Abstract

Tuberculosis, a highly contagious and lethal infectious disease, remains a global health concern with challenging treatment options. To combat its widespread impact, prevention strategies, such as vaccination, are imperative. This research focuses on developing a mathematical model with the addition of a vaccination compartment to understand the dynamics of tuberculosis transmission with vaccination. Subsequently, the study proceeds to identify the equilibrium points and calculate the basic reproduction number (ℜ0). Following this, a comprehensive stability analysis is conducted, and a numerical simulation is executed to observe the population dynamics. Furthermore, parameter sensitivity analysis is undertaken to assess the extent to which these parameters impact ℜ0. Preliminary analysis shows that the modified model has a solution that remains in the non-negative and bounded region. Furthermore, model analysis reveals two equilibrium points, namely the disease-free equilibrium and the endemic equilibrium. It is established that the disease-free equilibrium exhibits local asymptotic stability when ℜ0 1. Remarkably, the numerical simulation aligns with the analytical findings, reinforcing the robustness of the results. Analysis of the sensitivity of the parameter to ℜ0 shows that the parameter of the proportion of susceptible population entering the vaccination class has a significant effect on the value of ℜ0. The parameter of proportion of susceptible population entering the vaccination class has a negative effect on the number of populations with infection.

Abstract

The training on using the Mendeley application for Public Administration students at the Faculty of Social and Political Sciences, Universitas Pattimura, aims to enhance skills in managing references and citations systematically. The main issue faced by students is the difficulty in organizing references structurally and the risk of citation errors that can affect academic quality. This activity includes preparation, material delivery, and hands-on practice using the Mendeley application. The training is based on the Theory of Technology Acceptance Model (TAM), which explains how technology adoption can influence its effectiveness. The results show that students can manage references more systematically and gain confidence in writing academic papers, including final assignments. Moreover, the training positively contributes to improving the overall academic quality on campus. Beyond teaching the technical aspects of using the application, this training also raises students' awareness of the importance of academic ethics in reference management. Thus, this training serves as a strategic step to prepare students for academic challenges while promoting a stronger culture of scientific writing.

Abstract

Ebola Virus Disease (EVD) is an infectious disease with a high mortality rate which is caused by the virus from the family of Filoviridae, genus of Ebolavirus. Therefore, this research works on the developing model of Ebola disease spread with SLSHVEQIHR type. The purpose of this study is to analyze the spread of Ebola disease with the treatments, which are quarantine and vaccination. Then determine the equilibrium point and basic reproduction number (R0). There are two equilibrium points, the disease free equilibrium point and the endemic equilibrium point. The analysis results in the model show that if R0<1 than the disease free equilibrium point is locally asymptotically stable. If R0>1 than the endemic equilibrium point is locally assymptotically stable. Numerical simulations are performed to show the population dynamics when R0<1and R0>1.

Abstract

Mathematics learning has not yet integrated students’ entrepreneurial character and reasoning abilities. In response, this study aimed to develop a Problem–Project Based Learning (PPjBL) model to strengthen both aspects within the Linear Programming course. The PPjBL model was developed using the Borg & Gall research and development framework through stages of design, validation, and classroom trials. The final PPjBL syntax consists of six stages: problem orientation, organizing students for learning, guiding investigation, designing the project, implementing the project, and documenting project reports. Results from expert validation and two implementation trials showed that the model is practical and effective. The entrepreneurial character of students improved from the “start to grow” to the “being habit”. Meanwhile, mathematical reasoning ability increased in the high category, indicating progress in problem formulation, logical construction, deduction, interpretation, and generalization. These findings affirm that PPjBL serves as a transformative pedagogical framework capable of integrating cognitive reasoning and affective character development through authentic learning experiences. The model positions students as active problem solvers through engagement with real-world entrepreneurial problems. Future research may extend the application of PPjBL to other mathematical domains, emphasizing the cultivation of critical thinking, creativity, and collaboration as integrated outcomes of holistic mathematical education.
