Abstract

This research examines the implementation of the Panca Jiwa Program at the Annakhil Darunnajah Islamic Boarding School 6 Mukomuko, Bengkulu, which includes five main values: sincerity, simplicity, independence, ukhuwah Islamiyah, and freedom. Through qualitative methods, it was found that these values ​​were implemented through student activities, OSDA, and graduate service. Support from all elements of the lodge and routine activities are the main supporting factors, even though there are obstacles to limited resources and consistency of implementation. As a result, the Panca Jiwa Program is effective in shaping the character of students, but evaluation and monitoring need to be improved to optimize the program.

Abstract

Rubella is a common cause of childhood rash and fever. It is typically a mild infection but it can be serious condition in pregnant women, as it may cause Congenital Rubella Syndrome (CRS) in the fetus. The study aimed to model and analyze it in order to get picture about the dynamics of the rubella virus transmission. The paper discussed two models of rubella transmission involving child-bearing age women and newly born infants of infected mothers. The models are SEIR-IR without seasonality and SEIR-IR with seasonality. The results from the first model showed that a pitchfork bifurcation occurred in the dynamics of the solution of the system with constant infection rate and the increase of the infection rate value do not make impact to the incidence of rubella among infants. The second model involving seasonality gave interesting dynamics where big seasonality may lead to a more complex dynamics of the solution.

Abstract

This research develops a mathematical model of a natural phenomenon, namely sea snails that can release toxins (allelopathy) so that non-toxic sea snails become afraid. In addition, toxic and non-toxic sea snails share biotic resources. Based on the existing phenomenon, the model of fear effect caused by allelopathy in the competitive interaction model with shared biotic resources will be studied. In this system, three equilibrium points are obtained: extinction point of prey, extinction point of predator, and coexisting point under certain conditions. Analysis of local stability at equilibrium points by linearization shows that all equilibrium points are asymptotically stable with certain conditions. Numerical simulations at the equilibrium point show the same results as the analysis results. Then, numerical continuity was carried out by selecting variation of the fear effect parameter for Numerical continuity results show that changes in these parameters affect the population of toxic and non-toxic species, marked by the emergence of Transcritical bifurcations, Bifurcation occurs at the first Saddle-Node bifurcation at and the second Saddle-Node bifurcation at

Abstract

Chimeric Antigen Receptor (CAR) T cell therapy has shown remarkable clinical outcomes in B cell Acute Lymphoblastic Leukemia (B-ALL). The treatment can utilize the immune system to recognize and kill leukemia cells through the CD19 antigen target.  However, the CD19 antigen is also expressed on normal B cells, which can cause side effects in B cell aplasia.  This study modifies a mathematical model of the interaction between CAR T cells, leukemia cells, and normal B cells by introducing the assumption that leukemia cells follow logistic growth dynamics. Determined the equilibrium point and continues to analyze stability using linearization and the Routh-Hurwitz criterion.  The analysis reveals four equilibrium points, including a state where leukemia cells grow at maximum capacity in the absence of CAR T cells.  Bifurcation analysis shows the occurrence of both transcritical and subcritical Hopf bifurcations, with distinct patterns compared to previous models.   A heteroclinic cycle was also identified, indicating that relapse may occur even after remission.   The logistic growth and B cell progenitors not only shape remission and relapse dynamics but also explain the dual role of B cells in sustaining CAR T activation and causing complications such as Cytokine Release Syndrome (CRS). This provides new insights for understanding therapy outcomes and optimizing CAR T cell treatment strategies.

Abstract

Despite the growing advocacy for integrating financial literacy into mathematics education, existing models rarely align financial concepts explicitly with mathematical competencies. This study introduces Mathematics-based Financial Literacy (MFL) and develops a novel conceptual framework that integrates financial literacy with key mathematical competencies, aiming to enhance students’ critical financial decision-making skills. The framework was constructed using a systematic methodology adapted from Jabareen, comprising four phases: literature review, pattern identification, category synthesis, and framework conceptualization, complemented by expert consultation. The development process involved deconstructing financial literacy concepts, identifying elements influenced by mathematical competencies, and synthesizing these elements into coherent categories to form a unified framework. The resulting MFL framework consists of four core content areas: financial calculations and transactions; risk and benefit analysis of financial products; tax calculations; and mathematics-based financial planning and management. These content areas are supported by six key mathematical competencies, which include reasoning and argumentation, communication, modelling, representation, problem solving, and the use of symbols and formalism, spanning three mathematical domains: quantity, change and relationships, and uncertainty and data. This structured mapping explicitly integrates mathematical competencies with financial literacy domains, providing a comprehensive and practical model for classroom implementation, while enabling teachers to design effective learning tasks and assessments that foster students’ financial comprehension and informed decision-making. Thus, this study offers a novel contribution to mathematics education by presenting a conceptual framework that systematically links financial literacy and mathematical competencies, supporting the implementation of measurable and relevant financial skills-based learning for students.

Abstract

Several species in the world have experienced extinction. To save species from extinction, a system needs to be formulated, one of which is protecting prey. Changes in physical and biological processes also have a role in the environment, namely resulting in dynamically changing carrying capacity. The rate of prey consumption by the average predator, i.e. the response function is also important in the system formulation. In this study, a prey-predator system was constructed with a Beddington-DeAngelis response function that considers prey protection and variable carrying capacity as well as a predation process that takes into account the predator population. In this research, the equilibrium point for prey-predator extinction, predator extinction, and coexistence was determined and then continued to analyze its stability. With a large prey protection value, the predator extinction equilibrium point is asymptotically stable and the coexistence equilibrium point is asymptotically stable, if and only if within a certain range of prey protection parameter values. In addition, simulations were carried out and it was concluded that at certain prey protection values, changes occurred in the stability of the system which depended on the limits of its carrying capacity.
