Abstract

The field of mathematics is a scientific discipline that can solve economic problems. This is because the field of mathematics can be used in dealing with financial audit problems that use images and numerical ideas in critical thinking. Apart from that, branches of mathematics such as the application of systems of linear equations can influence economics. Therefore, this research is intended to find out in more depth about the Application of Systems of Linear Equations in Economics. The aim of this research is to find the effect of implementing systems of linear equations in economics. To achieve this goal, the author uses library research methods with the aim of collecting data or information with the help of technology in the form of computers and various sources in libraries such as books, journals, articles and similar research results. From this research, several explanations regarding the Application of Systems of Linear Equations which can influence the field of Economics are produced, including: 1). The application of the Linear Equation system can influence Demand in the economic sector; 2). The application of the Linear Equation system can influence supply in the economic sector; 3). Application of a Linear Equation System can result in market balance (market equilibrium); 4). Implementation of a Linear Equation System can affect Tax; 5). Application of the Linear Equation System can affect subsidies. From the research conducted, the author hopes that it will become a reference in the world of economics and become a reference in carrying out efforts to improve the economy.

Abstract

The purpose of community service is to provide assistance to increase the acceptance of parents of children with special needs in the Autistic category. The method used is Psychoeducation. Psychoeducation is a method carried out to increase the acceptance of parents of Children with Special Needs in the Autistic Category. The participants in the dimming activity were parents of Children with Special Needs in the Autistic category, totaling 25 participants. Service participants have a pre-score, which is a low category in terms of parental acceptance. The method of psychoeducational activities consists of three main stages, as well as evaluation. In the preparation stage, the team first analyzed the needs of psychoeducation by conducting interviews with parents who have children with special needs in the Autistic category. Then, at the implementation stage, the activity included the delivery of material about parental acceptance of autistic children, the definition of Autism, the factors that cause Autism, sharing of the problems faced, and discussions. The results of the evaluation of this psychoeducational activity showed an increase in the average score from 22.40 in the pre-test to 67.20 in the post-test. Psychoeducation makes a positive contribution to the acceptance of parents of Children with Special Needs of autistic children. So that with increased acceptance from parents, it can increase the growth and development of autistic children through proper parenting.

Abstract

This study investigates the mediating role of Fear of Missing Out (FoMO) in the relationship among phubbing and social media addiction among undergraduate students. Excessive social media use and problematic smartphone behavior have increasingly been associated with psychological distress and addictive digital behaviors among young adults. Using a quantitative explanatory research design, data were collected from 291 undergraduate students through convenience sampling and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The measurement instruments were adapted from previously validated scales assessing phubbing, FoMO, and social media addiction. The findings revealed that phubbing had a significant positive effect on FoMO (β = 0.334, p < 0.001) and social media addiction (β = 0.359, p < 0.001). Furthermore, FoMO significantly predicted social media addiction (β = 0.671, p < 0.001). Mediation analysis demonstrated that FoMO significantly mediated the relationship between phubbing and social media addiction (β = 0.224, t = 4.98, p < 0.001), indicating a partial mediation effect. The structural model showed moderate explanatory power, with R² values of 0.540 for FoMO and 0.573 for social media addiction. These results recommed that psychological factors, particularly FoMO, provude to explaining how phubbing behavior is associated with dificult social media use among university students. This study contributes to the increasing theory on digital behavior by integrating behavioral and cognitive-emotional factors within a single structural framework.
