The steps of this study are namely; pre-study observation, analysis of learners, format design, prototyping encyclopedia, validation validator to three experts, instructional simulation, then revision 2, analysis results, publications and complete. However, research conducted groove only to the revision of the results of validation, further trials instructional simulation Encyclopedia Archipelago in the Context of the Homeland, which aims to determine the students' responses. This is caused by the limited learning time refers to the curriculum.The end result can be seen product validationon an average of the three validators expert and gain a percentage of 607.7%. while the resultsinstructional simulation product testing to students showa positive response of 96.9%. and the response was negative 0.31%.This proves that the encyclopedia is very interesting, it is effective to use in learning PPKn.
