Abstract : As environmental problems could not be easily solved, human interaction with nature is interesting to be studied. It meant that it talks about human behavior which is closely related to the environment. That was why the purpose of this research was aimed at finding out whether personality (Per) and motivation (Mot) affected that behavior (CB toward the environment). Therefore, a causal survey was used by selecting 89 employees of village-owned enterprises (BUMDES) in Indonesia. There were three instruments developed which measured CB employees toward the environment (CB, rel. was 0.84), big-5 personality (Per., rel. = 0.91), and motivation (Mot, rel.= 0.88). Data were analyzed by path analysis. The research results revealed that per. and mot. directly and significantly affected employees' CB, moreover, mot. has been found to be a good mediator between per. with employees' CB. Its indirect effect was found to be significant as well. Based on these findings, it could be concluded that if employees’ CB planned to be minimized its variation, both personality and motivation need to be considered. This will imply that in developing a policy, especially in recruiting new employees, those factors should be not logically neglected.
