Abstract
Many researchers make blind people the object of research to help them to provide solutions to the difficulties faced by these people, especially in carrying out daily activities. The oldest foundation that protects blind people in Indonesia is PERTUNI, as well as many other foundations such as the Karya Tunanetra Peduli Bangsa Foundation which has approximately 400 people with visual impairments spread across several regional coordinators in Jabodetabek d Bandung. One of the expectations of the foundation management is to be able to monitor the condition of its members when they are doing outside activities and be able to provide immediate assistance when such members face an emergency. This is the background of the problem that the researchers are trying to solve, by building a portal that can be integrated with visual aids, latitude, and longitude data for people who are registered in the portal, processed using the Haversine Method and Google Maps as support. The haversine formula is an equation that gives the distance of a large circle (radius) between two points on the surface of the sphere (Earth) based on longitude and latitude. Tests were carried out on the system using Blackbox and the accuracy of the haversine method using MAPE is 79% accuracy
