This research aims to reveal the perceptions, concept mastery and respondent action on micro plastics toward plastics in their surroundings. The subject of this research is chemistry teachers (n = 42) and university prospective teachers (n = 60) from Mataram city and suburb, Lombok Island Indonesia. The study focus on microplatics, including discussion about the definition, awareness, man and seawater biota health problem and chemistry concept. The data gained were analyzed by using descriptive-statistics. In this research, mix of qualitative-quantitative descriptive methods were implemented (conducted in two sessions of online learning) and observation offline meeting to do assessment that used instruments such as essay test, questionnaire sheets and CCTV recording in order to collect data. Our results show that the lesson was well received by teachers and student teachers, who also thought it was fascinating and positive. Respondents' understanding was boosted by incorporating different viewpoints on microplastics. From this work, we expect some of them will be ready to be hero/heroines to battle plastics debris due to reach zero plastics waste.
