Abstract

This study examines the influence of cognitive dissonance bias, overconfidence bias, and herding bias on investment decisions in stocks listed on the Indonesia Stock Exchange. The study employs a questionnaire method as a data collection technique, involving a sample of 150 respondents, all of whom are residents of West Kalimantan who invest in stocks on the Indonesia Stock Exchange. The data analysis techniques used include multiple linear regression analysis, multiple correlation coefficient (R), coefficient of determination (R²), simultaneous test (F-test), and partial test (t-test). The results of the study indicate that cognitive dissonance bias, overconfidence bias, and herding bias have a positive and significant influence on investment decisions. This suggests that these three types of behavioral biases play an important role in the individual investment decision-making process. In other words, when investors experience a mismatch between their beliefs and new information, exhibit excessive self-confidence, or tend to follow the decisions of the majority, they are more likely to make investment decisions without thoroughly considering rational analysis. These findings highlight the importance of understanding investor psychology and financial literacy in minimizing the impact of cognitive biases. Proper education and enhanced awareness of financial behavior are expected to help investors make more objective and rational decisions, thereby reducing potential losses and improving the quality of investment decisions in the capital market.

This type of research is quantitative research. The method used in this study is a quasi-experimental design with a non-equivalent control group. The study population was 543 students with a sample of 66 students determined randomly purposive sampling. The data were analyzed using descriptive statistics, normality test, homogeneity test, and hypothesis test in the form of t-test with the help of SPSS versi 29 for windows program. Based on the results of the study on students communication skills, the average postest results of students in the experimental class were 81.15 after being given learning using the RADEC learning model, while in the control class it was 71.67 after being given learning using the lecture model. Meanwhile, based on the results of the study on students higher order thinking skills, the average postest results of students in the experimental class were 82.09 after being given learning using the RADEC learning model, while in the control class it was 71.09 after being given learning using the lecture model. Based on the results of the t-test on students communication skills, it is known that t count is 5.666>t table of 2.000. While the results of the t-test on students higher order thinking skills are known that t count is 3.900>t table of 2.000. Thus, it can be concluded that the RADEC (Read, Answer, Discuss, Explain, and Create) learning model has an influence on communication and high level thinking skills in elementary school science learning.

Using a positive data collection strategy and a sample size of 150 participants, this study adopts an associative methodology. Eligible participants are Pontianak City residents aged 17–44 years and PayLater users. Statistical methods employed in the analysis include multiple linear regression, correlation and determination coefficients, simultaneous testing (F test), and partial testing (t test). The analyzed data is linear, normally distributed, and shows no signs of multicollinearity, as confirmed by the classical assumption test. The research variables exhibit a strong relationship, as indicated by a correlation value of 0.753. According to the coefficient of determination (R²), the variables examined in this study explain 56.7% of the variance in financial behavior, while the remaining 43.3% is influenced by other factors not addressed in this study. Preliminary findings indicate that financial literacy and financial self-efficacy significantly influence financial behavior positively. In contrast, financial stress has a positive effect but is not statistically significant in influencing financial behavior.

Abstract

This study aims to analyze the level of cognitive presence among lecturers and students in MOOCs-based online learning at ICE Institute using the Community of Inquiry (CoI) framework. The study employed a quantitative descriptive approach. The instrument was adapted from the CoI Survey and validated through expert judgment. The respondents consisted of 38 students and 10 lecturers who actively participated in courses at ICE Institute during the odd semester of 2024. The sampling technique used purposive sampling with the criterion that respondents had completed at least four weeks of lectures. Data were analyzed using descriptive percentage statistics and proportion difference tests. The results showed that 80% of lecturers were categorized as having a high level of cognitive presence, while only 50% of students reached a similar level. Furthermore, 47.3% of students were categorized at a moderate level and 2.7% at a low level. This 30% gap indicates differences in perception and cognitive capacity between lecturers and students. Lecturers were considered highly competent in designing learning activities based on critical reflection; however, students had not fully utilized these opportunities. The study recommends the need for pedagogical interventions such as cognitive scaffolding, collaborative project-based learning, and self-regulated learning training for MOOCs students.

Abstract

Background: Micro, Small, and Medium Enterprises (MSMEs) in West Kalimantan face substantial financial management challenges amid accelerating digital transformation. As a border province geographically distant from Indonesia’s primary economic centers, Pontianak’s entrepreneurial ecosystem is characterized by informal financial practices, uneven digital infrastructure and limited access to formal financial services. These structural conditions create disparities in financial capability and digital readiness among MSME actors.Purpose: This study examines the effects of financial behavior, fintech development, online shopping platforms, and present bias on MSMEs’ financial planning, with digital literacy as a moderating variable within an integrated behavioral–technological framework.Methods: A quantitative causal research design was employed using structured online questionnaires distributed to 262 MSME owners selected through purposive sampling. Six validated constructs were measured using a five-point Likert scale and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS 4.0 to assess both direct and moderating effects.Results: Financial behavior was the strongest predictor of financial planning, followed by online shopping platform utilization and fintech development. The present bias did not have a significant direct effect. Digital literacy showed no direct influence on financial planning; however, it negatively moderated the relationship between online shopping platforms and financial planning, indicating diminishing marginal returns of e-commerce utilization among MSMEs with higher digital capabilities.Conclusion: Behavioral financial discipline remains the cornerstone of MSME financial planning, regardless of technological sophistication. Digital tools contribute to financial planning when they are integrated with structured managerial practices rather than functioning as standalone solutions.Originality/value: This study extends behavioral finance and technology adoption theories within the urban entrepreneurial ecosystem of Pontianak. The identification of a negative moderating effect of digital literacy reveals non-linear and context-dependent dynamics between digital capability and financial planning outcomes, offering policy-relevant insights into inclusive digital transformation strategies in developing urban economies.
