Abstract

Jurang Piji Forest is a forest located in Argosari Village, Jabung District, Malang Regency. This forest is the main water source for the Argosari Village community. This water source is very important because it is used by the surrounding community for daily needs, livestock, and agriculture. The main problem faced is the decreasing number of springs in the Piji Ravine Forest every year and 40% of deforested land around the water area due to illegal logging. Based on these conditions, reforestation efforts are needed to restore the function of the tree itself, which is to absorb water into the soil to preserve the springs. The reforestation activity was carried out in three stages, namely field observation, purchasing 200 seedlings, and planting trees in the Jurang Piji Forest. This reforestation activity aims to preserve the forest and maintain the sustainability of spring water sources in the long term. The result of this reforestation activity is the successful planting of 200 trees along the waters of Jurang Piji Forest. The benefits of all this are expected to become a routine program for the village and for future KKN.

Abstract

Positioning risk tolerance as a mediating variable, this study investigates the extent to which overconfidence, optimism bias, and financial literacy shape stock trading frequency among Generation Z investors in Malang City. A quantitative approach with an explanatory design was employed, with purposive sampling used to select 100 respondents. Data were gathered through a questionnaire instrument and subsequently analyzed using SmartPLS 4.0 software via SEM-PLS method. The results indicate that overconfidence, optimism bias, and financial literacy all bear a positive and significant influence on risk tolerance. Interestingly, not one of these three variables was found to produce a direct effect on stock trading frequency. Risk tolerance was demonstrated to serve as a full mediator in the relationship between the independent and dependent variables, while at the same time yielding a significant positive effect on trading frequency. These findings point to the conclusion that the trading behavior of Generation Z investors in Malang City is governed far more by their individual level of risk tolerance than by psychological or cognitive factors operating in isolation.
