Development of Information Retrieval Method and Haversine Formula to Determine Clinic Recommendation in Jember

Clinic is a facility where people seek treatment and obtain medical advice and a place where medical students observe cases of illness suffered by patients. Currently, the presence of the Corona Virus (COVID-19) has made many clinics accommodate patients who have been exposed to the virus. From these cases, recommendations for determining the clinic are needed because the conditions are very emergency and positive cases are increasing every day. In this paper, information retrieval methods are added, namely the TF-IDF and BM25 methods to determine clinical recommendations in Jember based on keyword from users and sorted by similarity from the largest to the smallest. Meanwhile, the Haversine Formula method is used to select a clinic with a distance.
