Implementation of Haversine Formula on Location Based Mobile Application in Syiah Kuala University

Syiah Kuala University (Unsyiah) is one of the leading public universities in Sumatera where thousands of students are accepted and graduated every year. This means, that Unsyiah is visited by many people from various regions and backgrounds. Most visitors find it difficult to locate the building they want to visit. This is due to the lack of information regarding the buildings situated around Unsyiah. Based on this problem, an application is developed to solve the problem. The application built is an Android-based application by using the Location Based Service method. This application is useful as a guide map for visitors to reach the location and explore Unsyiah. The distance computation between two points is calculated using Haversine Formula. The Android based application is called Unsyiah Guidance Map and a web-based application is developed for administrator to insert building data. The application was successfully tested with blackbox testing. The usability testing for the application was using the System Usability Scale (SUS) method. The SUS score obtained was 84.36 that falls into B grade; this means that the application is acceptable and easy to use. The distance calculations tested 10 times using Haversine Formula and Google Maps Distance. These tests yielded an average difference value of 0.088 meters. With the help of SPSS software, it shows that both Haversine Formula and Google Maps Distance do not have significant differences. It can be concluded that Haversine Formula that was used on the nearest distance computation has small difference compared to Google Maps Distance.
