Keywords: Media Teaching, Interactive Whiteboard , Virtual Laboratory 1. Introduction The development of today's educational world is entering an era marked by incessant technological innovation, so it requires the adjustment of the education system in tune with the demands of the workplace. Vocational School (SMK) is designed to prepare students or students who are ready to enter the world of work and be able to develop a professional attitude in the field of vocational , and must be able to provide the competencies or skills that can improve the quality of graduates to achieve success [1]. Success in SMK size can not be separated from the name of the learning process and the lab . Some practical subjects other than the need to know the basic concepts and theories supporting , also must perform experiments / experiments in the laboratory to understand a certain concept or the basic theories that have been studied in order to have a broader understanding level. To carry out a lab activities will require several factors, including laboratory space in accordance with the practice subjects, facilities equipment, and a complete practice materials . Fact the field after the observation is found that there are many vocational equipment and materials that have very minimal practice, teaching media is still using conventional methods , there are even schools that do not have laboratory space,  20   20  so that the lab is not running optimally. Hope students are gaining the knowledge and experience of learning outcomes, while the teacher's expectations are practical learning process toward the achievement of cognitive changes, psychomotor , affective , and life skills enhancement students . To overcome these problems, in this study will be developed as a means of teaching media animation and 3 dimensional simulations along with the development of hardware-based touchscreen. To develop this, we need a media research development [2]. Based on the description of the background , so in this study some of the problems can be formulated as follows: 1) how to develop media that can enhance critical thinking skills and life skills of vocational students; 2) how to design media that can enhance students' critical thinking skills.  2 . LAVIR Planning Methodology This research is the development of research [3]. Software development models such as the medium of instruction for the virtual laboratory[4][5][6], carried out with the engineering approach where the stages are : analysis, design, implementation, and evaluation. Having produced a model of teaching media . This study is a type of research and development. In accordance with the understanding that this research aims to produce a product. The products produced in this study is in the form of interactive media and instructional practices touchscreen devices are expected to address the practical activities carried out using conventional equipment . The conceptual model is the embodiment of a multimedia and lab materials that make up the model LaVir ( Figure1). The development of this LaVir consider a few things, namely: 1) audience . Users of this application are the teachers and students of SMK; 2) output equipment . Because the learning materials will be used by teachers and students independently, then the required format suitable for interactive use, the touch-screen -based ; 3) image. Display with 3D images, such as backgrounds and illustrations that need to be made using 2D and 3D graphics software ; 4) audio. This application does not use a specific audio recording, but the recorded audio with the video as a whole ; 5) video . Video used in this application is a video showing the working principle of the working of a system or process that will be more easily understood and explained as compared to using a text ; 6) animation. 3D animation that shows the form in accordance with the scope of lab materials is practiced; 7) simulation. Practicum requires a process of selecting the components, assembling components, and perform testing of components through measurement tools . All processes that occur simulated in accordance with the real situation; 8) interactive tools. This application requires an interactive tool that is a button to switch to a specific view ; 9 ) virtual. Components and design rooms in the 3D shape is made equal to the real situation in terms of coloring, shape and perspective. So that would bring students into the atmosphere like a real laboratory practicum .  Production of CD-ROM is a multimedia stage where the whole object is created. To develop a program of measures required LaVir design as shown in Figure 1.  Fig.1 The design flow Touchscreen-based  teaching media  21   21   Making an application based on storyboards, navigation structure, or flowchart derived from the design stage. At this stage of the design created storyboards that depict the look of each frame. Interactive because that will be made is not simple, it is necessary navigational structure that can be used to define links from one frame to another frame as well as the effects of virtual visualization depicting a similar situation with the real reality. After the creation of application-Virtual Lab, all lab materials stored on a CD-ROM to be duplicated. While the hardware needed for the manufacture of such measures in Figure 2 as follows  Fig. 2 Hardware Design groove LaVir Up to Produce process Touchscreen  In Figure 2 looks LaVir hardware design flow to generate the touchscreen. Starting from the design determines what method will be used further specify what type of circuit that will be used, in this case a series that is designed to function as a touch screen. The design is shown in Figure 3.  Fig.3 Design Media Teaching from Touchscreen  Fig. 4 Position for the calibration process  The series of touchscreen consists of 2 parts namely the transmitter (TX) and receiver sections (RX), the communication between them using Bluetooth communication. For the communication process between them using the installed software testing is then performed either software (software) or hardware (hardware) prior to calibration for the touchscreen. Display Design for Virtual Laboratory Before the beginning of the product development process is a step that must be passed by a collection of material . Collection material can be done in parallel with the production phase . At this stage, the collection of materials such as animated videos that match the topics lab, for background audio, video and others needed for the next stage. If the material sought is not found , then it should make your own by using software that has been predetermined. Researchers in producing software LaVir media using a combination of measures of development measures which have been proposed by Borg and Gall , to adopt instructional design instructional Dick and Carey, and multimedia development in the adoption of Lee &  22   22  Owens . In outline at developing measures undertaken by researchers in this development is to construct a flowchart , story board, CD packaging, and manufacturing series of touchscreen. Products made using the main software Macromedia Flash MX, Macromedia Flash prof. 8, swift 3D, 3Ds Max and then produced the initial product LaVir media. LaVir initial product developed with the material presented by 10 lab experiments . The design of the menu display design model development and then used as the basis of the Virtual Laboratory (LaVir) to generated a learning software that can be used in practice to support activities in the laboratory as shown in Figure 5.10. Activities that occur in the virtual lab consists of modifying the circuit , building a circuit , put the circuit , take measurements and subsequent component is an evaluation of a series that have been made .
