Abstract
This study aims to find out how the feasibility and practicality of developing PAIKEM-based modules (Active, Innovative, Creative, Effective and Fun Learning) on colloidal system materials at SMA Negeri 1 Praya Barat. This research method uses research and development with the ADDIE model. The sample in this study was 70 students of class XI science at SMA Negeri 1 Praya Barat consisting of 23 students of XI IPA 1, 25 students of XI IPA 2 and 22 students of class XI IPA 3. Data collection instruments use validation sheets and practicality sheets. The data analysis technique of this study uses descriptive data. The results of this study are: 1) this learning module is declared very valid based on the calculation of the Aiken index, the average validation value of the five validators is 0.88; 2) the results of calculating the average percentage of practicality after the application of modules in class XI IPA 1 by 88%, XI IPA 2 by 81% and XI IPA 3 by 91% with very practical categories. Therefore, it can be concluded that the PAIKEM-based learning module on colloidal system material is worthy of use as a learning medium because it received a positive response with the category "very good" from class XI science students at SMA Negeri 1 Praya Barat.
