Mental Health and Learning Achievement during the Covid-19 Outbreak: A Lesson from Online Learning among Indonesian College Students

Introduction. All educational institutions have to adjust the learning format, from face-to-face to online learning, due to the COVID-19 outbreak. The sudden shifting of the learning format raised several problems for the students and led to mental health issues.Aim. This study aimed to examine the effect of mental health on students' learning achievement during online learning in the COVID-19 outbreak.Methodology and research methods. This study used partial least square structural equation model- ling (PLS-SEM) to examine the research model on a random sample of 518 respondents.Results. The online learning activities during the COVID-19 outbreak have developed mental health issues, such as anxiety and depression. Furthermore, the results indicated that mental health negatively predicted the students' learning achievement. Scientific novelty. This study reveals certain situations and conditions that could be affected to the student's mental health and learning achievement.Practical significance. This study can be useful to the government as policymakers and administra- tors of the university as current research provides a critical understanding of the online learning influ- ence on mental health and learning achievements of students. The government and administrators of the university should consider the right policy for learning activities during the COVID-19 outbreak. The government and administrators of the university also should provide student services to minimise the mental health issues among college students during online learning activities.

Covid-19 Pandemic: Empirical Study of Determinants of Purchase Decision

The purpose of this study was to determine the impact of lifestyle and price on purchasing decisions. Individual variables include lifestyle and price. The regulatory variable is the Covid-19 plague, and the dependent variable is the purchase decision. The survey data were obtained from a food factory (coffee shop) in Semarang. Population sampling is used. Data are collected through research methods such as direct surveys. Structural Equation Modeling (SEM) testing is used for data analysis. The model of the mathematical equation is used in a statistical test to show the effects of the independent variables on the dependent and controlled variables. The results of the study suggest that: 1) Purchasing decisions do not directly affect lifestyle. 2) The decision to buy has a negative effect on the price. 3) During the COVID-19 epidemic, lifestyle had a positive effect on purchasing decisions. 4) Transmission variable COVID-19 had a positive effect on purchasing decisions during the epidemic. Before the plague, prices were lower than usual, but coffee experts kept their distance, avoided crowds, and cared about their health. © 2022, World Scientific and Engineering Academy and Society.
