This study aims to explore how TikTok content is related to elementary school students' learning motivation. Using a descriptive qualitative approach, data was collected through interviews, observations, and documentation from five students, three teachers, and two student guardians at SDN 02 Serang. The results show that TikTok content has mixed effects on students' learning motivation; some students feel motivated by educational content, while others experience a decline in learning enthusiasm due to watching too much entertainment content. In addition, TikTok also plays a role in shaping students' social aspects, such as self-confidence and interaction skills. Proper mentoring is needed so that the use of TikTok can optimally support the learning process.

This study aims to extensively research the effects of cognitive biases on individual investment decisions. The population of this research is investors in Indonesia and the sampling technique used is random sampling, obtained 574 respondents from 34 provinces in Indonesia. Quantitative data were collected through structured questionnaires and analyzed using multiple linear regression and moderated-moderation model in the PROCESS Procedure for SPSS Version 4.1 by Hayes. Results indicate that herding bias has a negative influence, discouraging investors from following market trends, while loss aversion, framing, anchoring, and mental accounting positively impact investment decisions; these biases are moderated by demographic factors. The findings imply that demographic factors do not interact jointly but operate independently to impact investment behavior. This research is novel in its exploration of moderated-moderation effects to reveal nuanced interactions between cognitive biases and demographics in shaping investment decisions.
