Abstract
Plastic litter is a global problem that threatens marine environment. The increase in plastic production is in line with the increase in the amount of plastic litter that pollutes the marine environment. This is due to a lack of awareness of the dangers of plastic litter which threatens the marine environment. This research was quantitative descriptive research in the form of a survey. The research aimed to find out how aware biology teacher candidates (BTC) are of marine plastic litter (MPL) issues. This research involved 204 biology education students of FKIP UMRAH. The research was carried out in June 2022. Data was collected using a questionnaire. Data was analyzed descriptively quantitatively. The results showed that students have good awareness of the MPL issues. This could be seen from students’ perceptions regarding the causes of the MPL issues and the impact of MPL. It was also demonstrated by students’ active participation in overcoming the MPL issues with a good category, as well as students’ behavior towards MPL which can threaten the marine ecosystem and the life within it with a very good category.
