Abstract
Plagiarism in research can occur due to accident or intentional. Plagiarism is an act that violates copyright and includes actions that harm others. In submitting the title of the research, for example, for the final assignment research, not a few students who repeatedly submitted titles were rejected and considered doing plagiarism because the title proposed had already existed before. Then we need a system that can detect the similarity between the titles to be submitted and the existing titles so that it is expected to reduce the occurrence of plagiarism. This study uses a winnowing algorithm to find the percentage similarity between titles. The Google Scholar will be used to obtain data on research titles that have been previously available as comparison titles. Web scraping with CURL (Client URLs) and simple HTML DOM parser is used to retrieve title data from Google Scholar. The results of the study with the application of a Winnowing algorithm to find the percentage similarity to data from Google Scholar were able to present a percentage of similarities in percent with the category of mild, moderate or severe plagiarism, while also helping early detection as prevention of plagiarism.
Highlights
Determination of whether or not a title of the Final Project is acceptable and to find out whether the title already exists or not currently done is through control and selection of the lecturers or supervisors

Data from research titles that have been available on Google Scholar, which include online journals from scientific publications [4] can be used to assist in obtaining other pre-existing titles as a reference or similar titles
Summary
Determination of whether or not a title of the Final Project is acceptable and to find out whether the title already exists or not currently done is through control and selection of the lecturers or supervisors. Previous research [16], [17], [18], [19], [20] has been carried out, but each study has not collaborated and utilized Google Scholar resources, as comparable data for the Final Project title using the Winnowing Algorithm. Based on these problems, to reduce plagiarism and detect early submission of student research titles, a study was conducted entitled "Web Scraping and Winnowing Algorithms for Plagiarism Detection of Final Project Titles"
