Development of E-Interactive Module Starter System Maintenance with Discovery Learning Model

The development of ICT has influenced the development of learning media that are increasingly interesting and interactive.  But there are still many students who have  a low enthusiasm for learning, this can be seen with the number  of students who rarely attend,  do not focus on learning, lack of motivation to learn.   Based on the results of observations and interviews, it was found that the learning of  starter system maintenance for some students is difficult to understand learning,  stammering time  and  study space, learning  is only in the form of job sheet handouts and power point slides from the teacher , students  only take notes  and are confused when  repeating lessons at home, lack of reference sources when making assignments, low interest and motivation in learning, teacher-centered  learning  , students are less active and cannot measure their learning outcomes independently so  that it is indispensable   learning by using e-modules. This study aims to develop learning media in the form of  interactive    e-modules for  Starter  System Care with a discovery learning model  that meets the validity aspects of the media. The research method used is the development (R&D) of the 4-D model, including the Define, Design, Develop and Disseminate stages, but the Disseminate stage is not carried out. The results showed validity in the validation of learning media with Validator 1 of 91%,  Validator 2 of 96% and  Validator 3 of 83%  with an average  of  90%  of  very valid categories. In the validation of material in  the e-module, the results  on Validator 1 were 9 3   %,  Validator 2 96% and Validator 3  9 6%   with an average of 9 5% very valid categories. Based on the results obtained, it shows that the learning media of the  Starter  System Care  interactive e-module with the discovery  learning  model is feasible for students in learning.
