What is Plagiarism?

Plagiarism is the act of taking credit for someone else's words or ideas. It's an act of intellectual dishonesty, and it comes with serious consequences. It violates university honor codes and can cause irreparable damage to a person's reputation. A plagiarized assignment may lead to a failing grade, a suspension, or an expulsion.

Clearly, the issue is not to be taken lightly. However, if you act with academic integrity, it's also nothing to fear. The best way to avoid accidental plagiarism is to understand the concept itself. 

Types of Plagiarism

Some forms of plagiarism are obvious. Copying someone else's essay word for word and submitting it as your own? Plagiarism, of course. Turning in an essay you bought from a paper mill is, too. The issue is not always so blatant, however. In addition to overt acts of academic dishonesty, other, more complex forms of plagiarism nonetheless lead to similar consequences :

1.  Direct plagiarism is the act of copying another person's work word for word. Inserting a paragraph from a book or article into your essay, without including attribution or quotation marks, is direct plagiarism. Paying someone to write an essay for you and submitting the essay as your own work is also direct plagiarism. If you commit direct plagiarism, you're likely to be caught thanks to software and tools such as Turnitin.

2.  Paraphrase plagiarism involves making a few changes (often cosmetic) to someone else’s work, then passing it off as your own. Unless an idea is common knowledge, you cannot include it in your paper without providing a citation—even if you do not include any direct quotes.

3.  "Mosaic" plagiarism is a combination of direct and paraphrase plagiarism. This type involves tossing various words, phrases, and sentences (some word for word, some paraphrased) into your essay without providing quotation marks or attributions.  

4. Accidental plagiarism occurs when citations are missing or sources are cited incorrectly. Accidental plagiarism is often the result of a disorganized research process and a last-minute time crunch. Ultimately, if you fail to cite your sources appropriately, you've committed plagiarism—even if you had every intention of giving credit.

So, If you want to copy and paste, don’t forget to insert the credit of source of the essay, the work even the opinion from other people (oral or writer) because if you do plagiarism you will get punishment. There is a law of plagiarism from Republic of Indonesia Law Article paragraph (2) “Lulusan perguruan tinggi yang karya ilmiahnya digunakan untuk memperoleh gelar akademik, profesi, atau vokasi terbukti merupakan jiplakan dicabut gelarnya.” Law Article 70 “Lulusan yang karya ilmiah yang digunakan untuk mendapatkan gelar akademik, profesi, atau vokasi sebagaimana dimaksud dalam pasal 25 atau (2) terbukti merupakan jiplakan dipidana dengan pidana penjara paling lama dua tahun dan/atau pidana denda paling banyak Rp. 200.000.000,- (dua ratus juta rupiah).”
