Abstract

The calculation of population projections in Indonesia at the provincial level is carried out by BPS using the component method, while at the district level it is done using the geometric method with the basic reference of calculating compound interest. From this, it is necessary to take another approach in calculating the projected population in the province of the Special Region of Yogyakarta. This study aims to determine population projections in the Special Region of Yogyakarta using exponential and logistic models based on growth rate and carrying capacity. The data used in this study is secondary data from the Central Bureau of Statistics of the Special Region of Yogyakarta in 2017–2022. The research method used is to determine the research subject, collect data, analyze the data, and draw conclusions. The result of this research is that the carrying capacity of the Special Region of Yogyakarta is 10,652,814 and the population growth rate for the logistic model is 0,02048.

Abstract

Leukemia, a type of blood cancer that originates in the bone marrow, is characterized by the uncontrolled growth of abnormal blood cells, which disrupt the normal functioning of blood cells. Chimeric antigen receptor (CAR) T-cell treatment, a form of immunotherapy, utilizes genetically modified T cells to specifically target and eliminate cancer cells. This treatment has shown promising results for leukemia patients who are unresponsive to chemotherapy or other therapies, as well as those who experience relapses.  In this study, we develop a mathematical model of leukemia that incorporates chimeric antigen receptor (CAR) T-cell therapy. The model takes into account the logistic intrinsic growth rate of leukemia cells, which gradually declines over time due to limited resources within the body. There are four compartments in this model: susceptible blood cells, infected blood cells, leukemia cells, and immune cells. We have analyzed the equilibrium points and their local stability, determined the basic reproduction number, and conducted a sensitivity analysis.  Through numerical simulations, we observed that prior to treatment, the number of leukemia cells in the blood escalated rapidly towards endemic conditions. However, after receiving CAR T-cell therapy through external infusion, the leukemia cells either became extinct or took a significant amount of time to reach endemic levels in the blood. Sensitivity analysis revealed that the growth rate of cancer cells (r) and the death rate of immune cells (significantly contribute to the increase in the basic reproduction number (.
