Waste Management Program to Create Zero Waste in School Level: Communication, Information, and Education (CIE) and Participation Methods.

In low-income countries, 90% waste accumulates in landfills without sorting processes and some are even eliminated by burning it. In 2019, the amount of waste in Depok reaches 1,300 tons every day, there is an increase from the previous year. Data shows that public sectors, such as schools, contributes 5% of the total waste. Based on this condition, the researchers held community service activities in schools to give motivation in managing the waste to reduce the volume of waste in landfills. The methods used were quantitative and qualitative. The activities held were in the form of training, improvement of soft skills in processing waste and preserving the environment, as well as monitoring and evaluation activities. From the results of the post-test scores after the training, it was found that the teachers' insight increased by 28.3%, while in the students by 25%. Adiwiyata school criteria achievement score also increased by more than 60% in each school. However, we need to know that changes in behavior cannot occur in a short time. Continuous change requires time and a strong commitment to ensure that the program continues to run routinely in the coming years. [ABSTRACT FROM AUTHOR]
