This study aims to improve the environmental literacy of the community around ASGM regarding the mercury dangers to health and environment. Raising the community environmental literacy is carried out through a mercury dangers awareness campaign by playing videos of mercury dangers, distributing mercury-free gold processing leaflets, resources person explanation concerning mercury impact. Public knowledge about the dangers of mercury before and after the campaign was measured through questions.
