A A boarding house is a temporary residence that provides several room facilities at a price determined by the owner of the boarding house and the length of time the rental is determined by the tenant of the boarding house. Kosan is usually located near the location of the tertiary institution where students from the area study at the tertiary institution. Trisakti University is a tertiary institution located in the administrative area of West Jakarta. The strategic position of the Trisakti University campus makes students interested in pursuing education at the Trisakti campus. The large number of students both from within the city and immigrants has made many people around the campus open boarding rental services. However, there are many boarding house rental service providers as well as limited information and time, making it difficult for students to find boarding houses. In addition, students want to get a kos with the closest distance to the campus, which has suitable facilities and is in accordance with the price set by the owner of the boarding house. So we need a system that can search the nearest kos around the Trisakti campus. Based on the problems described above, researchers will create a search system for the closest kos using the Website-based Depth-First Search (DFS) method in the Trisakti campus area. So that with a website-based search system for the nearest kos in the Trisakti campus area, it can make it easier for the community, especially Tritsakti students, to search for the closest kos from campus.
