The one of increasing learning quality is used module, because it (module) more easier to learn by learner withself access centre in home and learning with it (module) to be focused on mastery competence from material study bylearner be based on time surely with potential and condition until the result of study be increase. The purpose of thisresearch is to produce of learning instrument in the form of conventional ignition system module at following CD oflearning. Wich used on learning and teaching activities. There is a problem to be presence of how to make module afollowing CD of learning on vocational competence refer to repaired ignition system and how to used it (module) withCD of learning. Wich the implementation at Kasiman vocational high school (specially second grade/TKR 2) andBojonegoro vocational high school (specialy second grade/TKR3).This research is the one of frame work research to used the module instrument and CD of learningwith the title is“repairing conventional ignition system”. This type of research to module of adoption development learning 4-D (fourD model) by Sivasailam Thiagarajan, Dorothy S, Semmel and Melvyn I. Semmel 1974 is consist of four slep that isdefine, design, develop and disseminate. The advisability module to be determines of result validity language divisionby professional lecture and two professional teacher. Validity of design area by one professional lecture and twoprofessional teacher. Validity of technique area by one. Professional lecture and two professional lecture and twoprofessional teacher. And validity of evaluation scoring question by one lecture professional. After the validationmodule and improvement/revition. To do that about scoring module on the student at kasiman vocational high schoolfor to know about the positive respon from student to learning activities used the module.The achived result is had been finished a module about repairing ignition system with following CD of learningis good. Validation result and to take experiment data directly at two school. Difference is to get good result. So themodule of conventional ignition system with following CD of learning is a good and prefer to used in the next learningactivities.
