Abstract

BP Batam, together with the Banjarnahor Family of Batam City, planted 1000 mahogany trees located in the Water Catchment Area of the Duriangkang Reservoir, Batam City. The development of Batam City as an industrial area must be balanced with sustainable greening to maintain water discharge for the needs of the Batam City community. Batam City's water catchment consists of seven reservoirs that serve as raw water sources for the city, namely: Sei Ladi Reservoir, Sei Harapan Reservoir, Muka Kuning Reservoir, Tembesi Reservoir, Mongak Reservoir, Nongsa Reservoir, and Duriangkang Reservoir. Seeing the increasingly high population growth of Batam City, BP Batam and the Banjarnahor Family jointly carried out a collaborative action to plant 1000 Mahogany trees in the DTA (Water Catchment Area) of the Duriangkang Reservoir. This collaborative tree-planting action by BP Batam and the Banjarnahor Family was also supported by the Sei Jang Duriangkang River Flow Management Center and involved 100 volunteers from the Banjarnahor Family along with BP Batam employees.

Abstract

This study aims to examine the influence of regret aversion bias, herding behavior, and risk tolerance on the investment decisions of generation z in Batam City. A quantitative approach was employed using primary data collected through questionnaires distributed to 100 generation z respondents who have prior investment experience, selected using a purposive sampling technique. The data were analyzed using multiple linear regression with the assistance of IBM SPSS version 26. The results indicate that, on a partial basis, regret aversion bias and herding behavior have a positive and significant effect on investment decisions, while risk tolerance does not show a significant effect. However, when tested simultaneously, all three variables have a significant impact on the investment decisions of generation z. Therefore, this study concludes that psychological and behavioral factors play an important role in shaping generation z’s investment decisions, particularly under conditions of market uncertainty.
