Implementation of Load Balancing Technology Using Raspberry Pi as a Server for Computer Based Examination

Since 2014, the Indonesian government has implemented a computer-based National Examination as a substitute for paper-based National Examination. Schools that conduct computer-based National Examinations should provide the Server as a provider of questions for students to work on. Not all schools have sufficient funds for server procurement. This research demonstrates load balancing technology in the server of computer-based examination at an educational institution using Raspberry Pi as a first step to handling the computer-based National Examination. Raspberry PI is a relatively low-cost single-board computer technology that will serve as a solution to reduce costs for conducting the computer-based examination. This research using PPDIOO method as a research methodology to design and implement the Raspberry Pi as a load balancing server for the computer-based examination server. The result shows that Rasberry Pi can be used as a server and the load balancing technology can also be implemented to improve the access quality of user in the server.
