I agree. Teacher code of ethics is very important and should be enforced. Due to the existence of the code of ethics, the teacher will be more responsible and can perform their duties professionally.
The code of ethics is the "rambu-rambu" atau “fence” for teachers to avoid or prevent unhealthy behaviors and actions. In essence, the task of the teacher is very noble, because it becomes a light for the students as future generations of the nation.
Therefore, teachers need to adhere to the code of ethics for the good of the teacher profession itself.
