This research is motivated by the amount of information offered on various webs. The large number of relevant websites related to the information sought causes users to have to search for the desired information one by one on the web so that the time required becomes longer. This research uses web scraping and TF-IDF method. Web scraping is a technique for getting information from web pages. In doing scraping, curl and simple html dom are needed to parse the scraped data. TF-IDF is a method to perform a search by looking for similarity of data with the keywords entered so that by using TF-IDF it is hoped that information that is more in line with the keywords entered is obtained. By using web scraping, additional data can be added to the system without using a web service. The use of TF-IDF results in a better search because the search is done by comparing the similarity of words between the data in the system and the search keywords.
