Over the course of three days, an engaging waste management program unfolded at this elementary school, drawing active participation from approximately 100 students. The initial day featured an enlightening presentation by us, elucidating practical waste management strategies for daily living. The following day transpired as a hands-on field activity, where students meticulously collected and sorted waste into organic, inorganic, and residual categories. On the culminating day, a spirited competition ensued, with 17 student groups delivering presentations on various waste management issues, showcased through posters, videos, and other creative mediums. The distinguished winners were awarded vouchers from a prominent stationery shop in Denpasar, affording them the opportunity to procure essential stationery supplies tailored to their needs.
