Implementation of Digital Signage Based on Embedded System and IoT Using Mac Address as an Identifier on Laboratory In-Out Announcer Board Heruwanto Department of Electrical Engineering and Information Technology Engineering Faculty, UGM Yogyakarta, Indonesia heruwanto@ugm.ac.id I Wayan Mustika Department of Electrical Engineering and Information Technology Engineering Faculty, UGM Yogyakarta, Indonesia wmustika@ugm.ac.id Selo Department of Electrical Engineering and Information Technology Engineering Faculty, UGM Yogyakarta, Indonesia selo@ugm.ac.id Abstract— The rapid development and utilization of information technology, mostly in the use of digital signage and Internet of Thing (IoT) have penetrated into all areas where the implementation has so many benefits and convenience. Hence, the implementation of IoT-based digital signage for in-out lecturer announcement board and staff is deemed important to be done, particularly in supporting the concept of smart laboratory applied in the Laboratory of Electronic Systems Department Electrical Engineering and Information Technology, Faculty of Engineering UGM. The implementation of IoT-based digital signage for in-out lecturers and staff members of the Electronic Systems Laboratory is developed by means of WEB-based interface, while for the identification of laboratory members existence it uses Raspberry P as an embedded system by utilizing user-owned device mac address connected to the laboratory Wi- Fi hotspot. The in-out status is always updated automatically according to the connectivity of laboratory member's devices with Wi-Fi hotspot. Keywords—Digital signage, Embedded system, IoT, Mac Address I. INTRODUCTION Nowadays the use of digital signage by means of embedded system and IoT is commonly to find in modern smart building. Digital signage is a centrally managed through digital media network aimed to display information, entertainment, and advertising [1]. The use of this medium until today has been very extensive and can be found in several scenarios, such as information on departure at the airport, guide visitors in a building, and the menu information in a restaurant. However, the main focus of this medium is to display information with dynamic and manageable content. Embedded System is a computing system or mini single board computer that has hardware specifications that almost resembles a PC in general but with hardware capacity such as hard drives, RAM, and a limited processor and with one particular purpose. Generally, Embedded System is commonly used by the developers of embedded technology to create a tool requiring the PC as the main media. but by using a relatively less power level. Usually Embedded System is widely used as a mini server up to remote devices, which can be controlled remotely. The power used varies from 5 VA to 12 VA. For the specification itself vary according to the provider's of Embedded PC [2]. Raspberry Pi is an Embedded System in the size of a credit card with high performance. It is programmable, affordable price, and applicable as a platform to interface with various devices [3]. Like most microcomputers, Raspberry Pi also uses a basic operating system, which is Raspbian - a development of Linux. There are a number of basic applications on the Raspbian operating system such as browsers that can display the webpages [4]. Also, Raspberry Pi can run the python programs to access the database. The current condition in the Electronic System Laboratory actually has the available status board in-out lecturers as well as board announcement Laboratory in the form of whiteboards. In practice, the use of status boards becomes ineffective as the information is very limited and often not updated properly. For this, the students looking for a certain lecturer in turn are forced to ask Laboran, or people who are in the Laboratory. The addition of Lab members is very troublesome because they have to order the stickers to be attached, and when the backup slot is exhausted, then it can no longer be added. From the existing condition, the Implementation of Digital Signage Based on Embedded System and IoT Using Mac Address as Identifier on Laboratory In-Out Announcer Board will make the board annaouncement more interactive because it is replaced by digital signage. Whilst, the identifier method will be replaced from manual to automatic using the Mac address connected with the wifi hotspot in the laboratory. II. METHOD The method used in the Implementation of Embedded Digital Signage and IoT Based System Using Mac Address As an Identifier on In-Out Laboratory Announcement Board is incremental prototyping. The incremental prototyping approach resembles to build some blocks in which the increment in each of new component has been added or integrated based upon an overall design solution. When all of the components were in place, the solution was complete. An advantage of this method is that we 2018 4th International Conference on Science and Technology (ICST), Yogyakarta, Indonesia 978-1-5386-5813-0/18/$31.00 ©2018 IEEE
