Abstract

This study explores the social functioning of persons with disabilities who use modified three wheeled motorcycles as a means of mobility and daily activity support. Using a qualitative approach with a phenomenological perspective, the research examines lived experiences related to independence, social participation, and role fulfillment within the community. Data were collected through in depth interviews and observations, then analyzed thematically to identify recurring meanings and patterns. The findings indicate that the use of three wheeled motorcycles contributes positively to mobility autonomy, access to social interaction, and the ability to perform economic and social roles. The vehicle functions not only as a transportation tool but also as a symbol of independence and self confidence. However, several challenges remain, including technical limitations, environmental barriers, maintenance issues, and social perceptions. Overall, the study highlights the importance of accessible transportation in strengthening social functioning and emphasizes the need for supportive policies, inclusive infrastructure, and community awareness to enhance the quality of life of persons with disabilities.

Abstract

Investment decision-making plays a crucial role in achieving optimal financial outcomes. However, investors frequently make irrational decisions due to psychological biases, one of which is overconfidence behavior. This study aims to empirically examine the effect of overconfidence behavior on investment decision-making among Indonesian investors. A quantitative research approach with an explanatory design was employed. Data were collected through an online questionnaire distributed to 52 investors selected using purposive sampling. The research instruments consisted of a six-item Overconfidence Behavior scale and a twelve-item Investment Decision-Making scale measured using a five-point Likert scale. Data were analyzed using descriptive statistics, reliability testing, normality testing, and simple linear regression analysis with IBM SPSS Statistics 24. The findings reveal that the measurement instruments are reliable, with Cronbach's Alpha values of 0.809 and 0.914, respectively, and that the data satisfy the normality assumption. Hypothesis testing indicates that overconfidence behavior has a significant positive effect on investment decision-making (F = 49.141; p < 0.001). The coefficient of determination (R² = 0.496) demonstrates that overconfidence behavior explains 49.6% of the variance in investment decision-making, while the remaining 50.4% is influenced by other factors. These findings support Behavioral Finance Theory by confirming that psychological biases significantly influence investment decisions and suggest that investors should balance self-confidence with objective financial analysis and comprehensive risk assessment.
