The purpose of this research is to produce practical module charging system IC Regulator to help study on courses Teaching of Automotive Electrical, and to obtain a response to the practical module chargingsystem IC regulators are to be tested against the students of the D3 in Mechanical Engineering Faculty ofEngineering Unesa. This research use approach to research the development of Dick and Carey with adescriptive quantitative analysis. Research conducted in the Department of Mechanical EngineeringUnesa. The object of research is the development of practical module system of charging IC Regulator.The techniques used in the development of data collection modules and question form which aims toknow appropriateness and the response of the module. Measures the process of developing practicalmodule charging system IC Regulator through several stages: (1) identification of the problem, (2) datacollection, (3) design products, (4) validation, (5) testing, (6) revision, (7) the finished product and can beused to study mechanical engineering student D3 Unesa 2009. Based on research results, obtained theresults that the module charging system IC Regulators developed viable for use in Automotive Electricalcourses. This can be seen on the basis of the results of the validation of the module by expert lecturerscontents of 81,81%, 77,08% of design experts and linguists of 85,71%, with average percentage of81,53% so categorized is well worth. The practical module system charging IC Regulators developed alsogets a good response by the student. It is shown with a percentage assessment of the readability module of78,43%. So based on the results of the validation of the module and an assessment of the readability bythe student module charging system IC Regulator can be categorized is worthy to be used as learningmaterials.
