Abstract

Coronavirus Disease 2019 (COVID-19) is a new type of virus from a large family of viruses transmitted between humans and animals (zoonotically transmitted) that was first discovered in Wuhan City, Hubei Province, China in late 2019 which is still widespread and threat throughout the world including Indonesia. This article discussed about the mathematical model of the spread of COVID-19 with vaccinations. In this case, the human population is divided into 5 classes, namely the suspected, vaccine, exposed, infected and recovered classes. The constructed model forms an SVEIR model that has two equilibrium points, namely disease-free and endemic equilibrium points. Stability analysis shows that the equilibrium point is stable local and global asymptotic if R0 1 and unstable if R0 1. Then a sensitivity analysis was carried out to determine the parameters that greatly affect the model as well as furthermore, numerical simulations are given to describe the behavior of the model that has been obtained based on the analysis of the sensitivity of basic reproductive numbers, obtained several parameters that affect the spread of COVID-19. Numerical simulation results show that vaccination can suppress the addition of infected populations and depend on the level of effectiveness of vaccination.

Abstract

This article studies the dynamics of a Gause-type predator-prey model with infectious disease in the prey. The constructed model is a deterministic model which assumes the prey is divided into two compartments i.e. susceptible prey and infected prey, and both of them are hunted by predator bilinearly. It is investigated that there exist five biological equilibrium points such as all population extinction point, infected prey and predator extinction point, infected prey extinction point, predator extinction point, and co-existence point. We find that all population extinction point always unstable while others are conditionally locally asymptotically stable. Numerical simulations, as well as the phase portraits, are given to support the analytical results.

Abstract

Spline is one of the nonparametric approach, to adjust data so the final model has good flexibility. The purpose of this research is to model the time series data in the form of currency exchange rates by using the nonparametric B-spline approach. In B-spline modelling, determination of the order for the model, and the number and the placement of the knot are the criteria that must be considered. The best B-spline model obtained based on the selection of the optimal knot points with minimum Generalized Cross Validation (GCV) criteria. The modelling in this research use data on the exchange rate of the rupiah toward the US dollar in the period January 2014 - December 2018. The best B-spline model obtained by the 2 point knot approach, at points 11935.10 and 12438.29, with GCV valueequals to 55683.09.Keywords: Nonparametric Regression; B-Spline; Generalized Cross Validation

Abstract

The fixed point theory remains the most important and preferred topic studied in mathematical analysis. This study discusses sufficient conditions to prove a unique fixed point in quasi-αb-metric spaces with cyclic mapping. The analysis starts by showing fulfillment of the cyclic Banach contraction and proving the Cauchy sequence as a condition for proving a unique fixed point in quasi-αb-metric spaces with cyclic mapping. Furthermore, it's shown that the cyclic mappings, T have a unique fixed point in quasi-αb-metric spaces. Finally, an example is given to strengthen the proof of the theorems that have been done.Keywords: fixed point theory; Quasi -Metric spaces; Cyclic Banach Contraction; Cauchy sequence. AbstrakTeori titik tetap termasuk salah satu topik penting dan menarik untuk diteliti pada bidang analisis.

Abstract

This study develops a two-dimensional predator-prey model incorporating logistic prey growth, prey group defense, alternative food, and ecological costs to the predator. The novelty of the model lies in the introduction of an alternative food quality parameter, which distinguishes the availability of alternative food from its biological effectiveness in supporting predator growth. The analysis focuses on the existence of equilibrium points, local stability, and forward bifurcation. The analytical results show that the model admits a trivial equilibrium, a predator-free equilibrium, and an interior equilibrium under certain existence conditions. The trivial equilibrium is always unstable, whereas the predator-free equilibrium is locally asymptotically stable when the quality of alternative food is below a critical value and loses its stability when the quality parameter exceeds this threshold. At the critical value, the system undergoes a forward bifurcation characterized by a stability transition from the predator-free equilibrium to a positive interior equilibrium. Numerical simulations confirm the analytical findings and illustrate three main scenarios: predator extinction when the alternative food quality is low, stable coexistence when the alternative food quality is high, and a stability transition through a bifurcation diagram as the alternative food quality parameter crosses its critical value. These results indicate that alternative food quality acts as a threshold parameter determining predator persistence and the transition from predator extinction to stable coexistence.

Abstract

This study discusses the effect of the Problem Based Learning model on students' mathematical creative thinking skills on cube and cuboid material. The research was carried out using an experimental method involving students of SMP Negeri 3 Limboto Barat as research subjects. The research design used is Post Test Only Control Design. Sampling was carried out using the Simple Random Sampling technique. Measuring mathematical creative thinking ability is done using a test instrument that has met the requirements of item validity and instrument reliability requirements. The results showed that applying the Problem-Based Learning model in learning significantly influenced students' creative thinking skills on cube and cuboid material. This can be seen from students' mathematical creative thinking ability in learning using the Problem-Based Learning model, which is higher than students' mathematical creative thinking ability in direct learning.

Abstract

Cluster analysis is a multivariate method that aims to classify objects into a cluster based on different characteristics. The statistical technique that can be used for clustering is Fuzzy C-means (FCM). The FCM uses membership degree to determine the existence of each data point in a cluster. To ensure accurate clustering and that the criteria are met, cluster validation must be done to produce good data clustering. Moreover, this study uses a discriminant analysis test to validate the results of cluster solutions. The study aims to classify 34 provinces in Indonesia based on the level of people's welfare. The data used in this study is data on indicators of people's welfare in Indonesia in 2021. The variables used in this study were age/life expectancy, the average length of schooling, the 16-18 years of enrollment, and households with proper access to water. Based on the study results, two clusters were formed: cluster 1, areas with low people’s welfare indicator values in 16 provinces, and Cluster 2, regions with high people's welfare indicator values in 18 provinces.
