Plagiarism Enforcement in Indonesia can be said to have not been quite effective because the plagiarism level is still quite high. In 2013 alone it was found that there were at least 808 cases of plagiarism in Indonesia. This needs to be studied more deeply, as was done by the authors in this article. With the subject matter of why this can happen, and whether the arrangement in Indonesia itself is quite effective. The results of the study show that the problem that is a weakness of the Plagiarism enforcement system in Indonesia is that it does not regulate Cryptomnesia-related Plagiarism that occurs when forgotten memories are returned unnoticed by the person concerned, who believes that memory is a new and first thing so that ideas arise without consciously imitating the work of others and as in line with Regulation of the Minister of Education Number 17 of 2010 that in implementing scientific autonomy and academic freedom, students / lecturers / researchers / education personnel are obliged to uphold honesty and academic ethics, especially the prohibition of plagiarism in producing scientific work, so that creativity in the academic field can grow and developing. Therefore, the copyright arrangement in Indonesia should be reconstructed without categorizing Crytomnesia as plagiarism.
