DEVELOPMENT OF MORAL MOVEMENT OF BRING YOUR OWN TUMBLER (BYOT) IN JUNIOR HIGH SCHOOL 3 JATINUNGGAL
School is one of the places that always produces waste every day, especially plastic waste. Of course this will have a bad impact on the environment, especially if the waste is not managed properly or recycled. Based on the results of surveys and observations conducted by researchers in November 2022
- December 2022, it shows that in one day the students of State Junior High School 3 Jatinunggal produce 311 plastic waste used as beverage packaging not including waste from food. Of course, if this continues to be allowed, besides having an impact on the environment, it will also have an impact on the health of the students themselves. In addition to the accumulation of used beverage packaging waste, the risk of diabetes also lurks in the health of students. Moreover, the Indonesian Pediatric Association (IDAI) released data on February 1, 2023 related to diabetes cases in children which increased 70 times as of January 2023 compared to 2010.This study aims to develop a moral movement Bring Your Own Tumbler (BYOT) at SMPN 3 Jatinunggal and measure its effectiveness in improving student behavior in reducing the use of disposable plastic drinking containers. The research method used was Research and Development (R&D) with six stages of development and implementation. The research subjects were seventh grade students at SMPN 3 Jatinunggal. The results showed that the development of the BYOT movement was successful and effective in increasing students' behavior in bringing tumblers to school and reducing the use of single-use drinking plastics. In addition, the BYOT movement also helped increase students' awareness about the importance of protecting the environment and maintaining cleanliness. This research proves that the BYOT movement can be an effective tool in improving students' environmental behavior and concern for the environment. Therefore, it is recommended to implement the BYOT movement in other schools to increase public awareness and concern for the environment.
