Abstract. The purpose of this research is a computer system can assist in detecting and
measuring plagiarism of scientific work quickly. There are many techniques that can be used to
measure the level of plagiarism of a document. in paper, we will use the Vector Space Model
and the research method used namely Cosine Similarity to measure the level of similarity of the
thesis. The result of this method was comparing the level of thesis similarity with the dataset
using the TF and TF-IDF techniques in graphical form. It can be concluded from the
experimental process, using the TF-IDF technique produces a smaller value compared to using
the TF technique.
