Abstract

The purpose of this study was to determine the validity of the project based learning model development on buffer solution materials with soft skill entrepreneur oriented, examine the effectiveness of the model, its influence on the soft skills of the entrepreneur, and study the response of students to the model. This study is the kind of R & D with project based learning model, scientific approach, method of discussion and experimentation. The results of the research in the category of very valid with a mean 94.77. Effective learning model with average learning outcomes 83.78 (> 80), N-Gain results of the Pre-test post-test of 0.74 (high category), t test of 4.11 (significant) and classical completeness 91.67% (higher than 85%). There is an effect of the project model on soft skills entrepreneur demonstrated by significance level calculation 0.00 (responsibility), 0.00 (confidence), 0.00 (cooperation), 0.01 (leadership), 0.03 (communication) , and 0.00 (problem solving) respectively <0.05. Learners provide an excellent response with a mean gain of 87.5%. From the results it can be concluded that the model and the device is valid, effective, has influence on the soft skills entrepreneur who developed, gets a positive response from students.
