How to fix is that our group will make signage regarding use dining hall clean like the garbage that is on the table, to throw or not to throw garbage onto the dining table.
The solution is for us to prepare the information board about the cleanliness of the cafeteria, such as garbage collection, which is on the table to the left. Do not leave trash or food on the table.
The solution is a group of us will also sign relations about cleanliness in the use of plant foods such as garbage on the table away. Or junk on the dining table.
