Gym information system using collaborative filtering for supplement recommendations

Gym and fitness are very important needs lately. Especially in today's era, where exercise is very important to increase endurance. The One Gym is a fitness center located on Jl. Bangau Pabean Sedati Sidoarjo. Currently, The One Gym still collects gym member data, recaps payments manually in books and does not yet use a system. Therefore, the purpose of this study is to design a website-based management information system where this system uses a collaborative filtering method. This information system will provide benefits not only to The One Gym but to new customers in the form of information needed and can be obtained quickly, precisely, completely and accurately which is certainly more effective and efficient without having to go through a difficult information search process. Based on the test results on the nine main functional aspects of the system, all features show a 99% success rate, which indicates that the system has met user needs and is ready to be implemented optimally.
