Design and Build Smart Presence Applications Using Android Based Location Based Services (Case Study: Polytechnic Caltex Riau)
AbstractThe process of student attendace at Politeknik Caltex Riau (PCR) still uses manual method. However, this method has several disadvantages, such as the risk of loss or destruction of attendance sheets, a long process of recapitulation time, and the possibility of falsifying attendance data. To overcome this problem the use of smart attendance application using Location Based Service (LBS) technology based on Android can be an alternative medium for students and lecturer. The result is that students can attend only by entering the room according Usability testing found that 56.4% of students and 73.3% of lecturers agreed that the application could reduce the cheating presence filling process. Then, the success rate of application in conducting presence in a room in an open corridor area is up to 60% and in a room in a closed corridor area up to 45%. When inside the room, being near a window is an area with a good degree of accuracy. The success rate is issued by a barrier that can blocking GPS signal or cellular signal. In addition, smartphones with dual-frequency GPS connectivity have the lowest accuracy error rate than smartphones with single-frequency GPS connectivity.
