Development of Desktop Application with Three Dimensional (3D) Pageflip Professional Based on Network Design and Construction Class XI TKJ

– This research and development aims to produce products in the form of E-Modules or electronic modules based on three dimensions (3d) Pageflip Professional in NETWORK DESIGN AND BUILDING Subjects (RBJ) Class XI Computer and Network Engineering (TKJ) at SMK Negeri 2 Padang. After the validity test has been carried out by the experts, the overall assessment of the validator test on the E-Modul or electronic applicationbased on three dimensions (3d) Pageflip Professional in the NETWORK DESIGN AND BUILDING (RBJ) Subject is 89.94%, so that the level of validity can be interpreted as valid. . The results of the overall practicality test assessment of the E-applicationbased on 3d Pageflip Professional in the NETWORK DESIGN AND BUILDING (RBJ) Eye is 89.50%, so that the practicality level can be interpreted as very practical to use. The results of the overall effectiveness test assessment of the effectiveness of the 3d Pageflip Professional-based E-Modul in NETWORK DESIGN AND BUILDING (RBJ) subjects are 90.63%, so that the level of effectiveness can be interpreted as very effective to use.


INTRODUCTION
Along with the development of the times and modern technology in the era of globalization, media is needed to advance an education and provide innovation in the learning process. The use of electronic modules as a tool in learning is expected to help students increase motivation, understand and understand the material presented [1]- [3].
The e-applicationin this study will be compiled and developed into a Desktop Application where the desktop application itself is an application that can operate offline, but we have to install it ourselves on a laptop or computer. Web application is a web-based application that can operate if there is a network/internet connection. so that later the model of a book page that can be animated is like a book that is turned over for each page that contains related material [4]- [6].
Based on the observations of researchers in Class XI TKJ of SMK Negeri 2 Padang, the learning outcomes obtained by class XI students of TKJ SMK Negeri 2 Padang in the subject of NETWORK DESIGN (RBJ) are still much below the Minimum Completeness Criteria (KKM). The cause of the low student learning outcomes is the lack of understanding and mastery of basic concepts in the NETWORK DESIGN AND BUILDING (RBJ) subject because students are lazy to carry and read textbooks on the grounds that they are heavy and bored with reading books that look static so that learning is still focused on teacher.
With this interactive electronic learning module, it is hoped that it will motivate students to learn, because it can display the presentation of material in an interesting and innovative way. By using this learning module, it is hoped that the learning process will be more active and students will be more skilled in solving the problems they face. Based on these problems, the authors feel it is important to develop modules with modules in this.

RESEARCH METHODOLOGY
This study uses the Research and Development (R&D) method, according to development research is a research method used to produce certain products and test the effectiveness of these products. Development research is not research that is intended to produce theory but to produce certain products, using the learning media development model used which refers to the type of development of four-D models which consists of 4 stages, namely Define (defining), Design (design), Develop (development) and Dessiminate (spread) [7]- [9].
The research method used in this research is the R&D method (Research and Development). Research and development methods or inResearch and Development in English is a research method thatused to produce a specific product, and test the effectiveness of the product. According to Amile and Reesnes (2015:297), Research and Development (R&D) is a research method used to produce a particular product, and test the effectiveness of the product. Based on the above definition can be explained that the R&D method is a research method used to produce certain products and to improve a product that is in accordance with the references and criteria of the products made so as to produce products that are through various stages and validation or testing. Researchers do research in advance to collect the required amount of data [10]- [13].
Next, system development is carried out and testing and evaluation of the system created. The flow of the development of Desktop Application with PageFlip Professional's three-dimensional (3D) based on productive subjects of TKJ RANCANG BANGUN NETWORK with a four-D model.
